Presentation on switching, routing concepts and configuration II. 1. OVERVIEW OF SWITCH What is switching? Networking concept has two basic concepts and they are Switching and Routing . They using one of these methods. are fundamental concepts in Networking ,other topics like network security are based on these concept. Routing and Switching are the base packet or data delivering methods in When we are talking about the switching ,the protocols and concepts are related to the layer 2 and data packets with in this layer that are called frame . re bigger and bigger and also more expensive. 10base5, 10base-T for cabling were used . . Better switches have more choices than 2 condition and because of this capacity, they In Networking there is a long history for switches. At first time the direct connection network and each device like router , switch , hub , firewall , proxy , cash server, modem are As you know the switch refers to the device that can select one condition from 2 or more conditions .For example an electrical switch can select 0 as turn off and select 1 for turn on between to or more computer used to make a network and such technology like 10base2, In those technologies , the base topology was BUS Technology and the most advanced of more devices for sending and receiving data , and when a device wants to send data for figure below we can see a logical view to a hub and the meaning of bus . II. 2. CONCEPTS OF SWITCHING this technology is HUB. A bus or data bus refers to the one link(shared link) between 2 or another device ,this bus should be empty and none of devices should not use the bus . In INTERNSHIP REPORT FIGURE 1: SWITCH II. 3.

OVERVIEW OF ROUTING is the process of selecting paths in a network along which to send network traffic. Routing is performed for many kinds of networks, including the telephone network (circuit switching technology.R outers switching), electronic data networks (such as the Internet), and transportation networks. This article is concerned primarily with routing in electronic data networks using packet II. II. 2. CONCEPTS OF ROUTING Whereas switches and bridges operate at OSI Layer 2 (the data link layer), routers primarily operate at OSI Layer 3 (the network layer). Like bridging, make the forwarding decisions. Routers make decisions based on network layer protocols such as Internet Protocol (IP) and Novell NetWare Internetwork Packet Exchange (IPX). growing beyond the capability of bridges. Before this popularity, networ he primary act of routing involves moving packets across a network from a source to a destination. The difference involves the information that is used to Routing gained popularity in the mid- to late 1980s as a result of internetworks Figure 2: Image of Router II. II. 3. SOME CONFIGURATION OF ROUTING modes, and the resulting prompts. The prompt helps you identify which mode you are in and, therefore, which commands are available to you: Mode of Operation Usage Mode How to Enter the Prompt The following table describes some of the most commonly used modes, how to enter the INTERNSHIP REPORT 10User EXEC Change terminal settings on a temporary basis, perform basic tests, and list system information. First level accessed. Router> Privileged EXEC Global Config System administration, set operating parameters. Modify configuration that affect the system as a whole. Modify the operation of an interface. Create the initial configuration. From user EXEC mode, enter enable password command Interface Config Setup From privileged EXEC, enter configure terminal. From global mode, enter interface type number. Router# Router(config)# Router(config-if)# Prompted dialog From privileged EXEC mode, enter command setup. User EXEC Mode:When you are connected to the router, you are started in user EXEC mode. The user EXEC commands are a subset of the privileged EXEC commands. P rivileged EXEC Mode: Privileged commands include the following: †¢ Configure – Changes the software configuration. Enter the command disable to exit from the privileged EXEC mode and return to user EXEC mode. †¢ Debug – Display process and hardware event messages. †¢ Setup – Enter configuration information at the prompts. INTERNSHIP REPORT 11 Configuration Mode Configuration mode has a set of submodes that you use for modifying interface settings, routing protocol settings, line settings, and so forth.Use caution with configuration mode because all changes you enter take effect immediately. Note: To enter configuration mode, enter the command configure terminal and exit by pressing Ctrl-Z. Almost every configuration command also has a no form. In general, use the no form to disable a feature or function. Use the command without the keyword no to re-enable a disabled feature or to enable a feature that is disabled by default. For example, IP routin g is enabled by default. To disable IP routing, enter the no ip routing command and enter ip routing to re-enable it.INTERNSHIP REPORT 12 Getting Help In any command mode, you can get a list of available commands by entering a question mark (? ). To obtain a list of commands that begin with a particular character sequence, type in those characters followed immediately by the question mark (? ). Router#co? configure connect copy Router>? To list keywords or arguments, enter a question mark in place of a keyword or argument. Include a space before the question mark. Router#configure ? memory Configure from NV memory network Configure from a TFTP network host terminal Configure from the terminalYou can also abbreviate commands and keywords by entering just enough characters to make the command unique from other commands. For example, you can abbreviate the show command to sh. INTERNSHIP REPORT 13 Configuration Files Any time you make changes to the router configuration, you must save t he changes to memory because if you do not they will be lost if there is a system reload or power outage. There are two types of configuration files: the running (current operating) configuration and the startup configuration. Use the following privileged mode commands to work with configuration files. show running-config – display the running configuration. †¢ show startup-config – display the startup configuration. †¢ configure terminal – modify the running configuration manually from the terminal. †¢ copy running-config startup-config – copy the running configuration to the startup configuration. †¢ copy startup-config running-config – copy the startup configuration to the running configuration. †¢ erase startup-config – erase the startup-configuration in NVRAM. †¢ copy tftp running-config – load a configuration file stored on a Trivial File Transfer Protocol (TFTP) server into the running configuratio n. copy running-config tftp – store the running configuration on a TFTP server. INTERNSHIP REPORT 14 IP Address Configuration Take the following steps to configure the IP address of an interface. Step 1: Enter privileged EXEC mode: Router>enable password Router#config terminal Example: Example, Step 2: Enter the configure terminal command to enter global configuration mode. Step 3: Enter the interface type slot/port (for Cisco 7000 series) or interface type port (for Cisco 2500 series) to enter the interface configuration mode. Step 4: Enter the IP address and subnet mask of the interface using the ip address ipaddress subnetmask command.Step 5: Exit the configuration mode by pressing Ctrl-Z Router(config-if)#[Ctrl-Z Router (config-if)#ip address 192. 168. 10. 1 255. 255. 255. 0 Router (config)#interface ethernet 0/1 II. III. NETWORK LAYER II. III. 1. OVERVIEW OF NETWORK LAYER INTERNSHIP REPORT II. III. 2. CISCO HIERARCHIAL LAYER 15 Hierarchy has many of the same benefits in network design that it does in other areas of life. When used properly, it makes networks more predictable. It helps us define at which levels of hierarchy we should perform certain functions.Likewise, you can use tools such as access lists at certain levels in hierarchical networks and avoid them at others. large networks can be extremely complicated, with multiple protocols, detailed configurations, and diverse technologies. Hierarchy helps us summarize a complex collection of details into an understandable model. Then, as specific configurations are needed, the model dictates the appropriate manner to apply them. The Cisco hierarchical model can help you design, implement, and maintain a scalable, reliable, cost-effective hierarchical internetwork.The following are the three layers: ? ? ? FIGURE 3 : CISCONHIERARCHIAL Each layer has specific responsibilities. However, that the three layers are logical and are not necessarily physical devices. Consider the OSI model, another logica l hierarchy. The seven layers describe functions but not necessarily protocols. Now, let's take a closer look at each of the layers. II. III. 3. CORE LAYER the core layer is responsible for transporting large amounts of data quickly The Core layer or Backbone The Distribution layer The Access layer and reliably.The designer must ensure that the core layer is designed with fault tolerance, especially because all users in the network can be affected by a failure. The ability to avoid unnecessary delays INTERNSHIP REPORT in network traffic quickly becomes a top priority for the network designer. What Happens at the Core Layer? 16 The core layer is sometimes called the network backbone. Routers and switches at the core layer provide high-speed connectivity. In an enterprise LAN, the core layer, shown in Figure 1-7, may connect multiple buildings or multiple sites, and may provide connectivity to the server farm.Goals of the Core Layer The core layer design enables the efficient, high-sp eed transfer of data between one section of the network and another. The primary design goals at the core layer are as follows: – Provide 100% uptime. -Maximize throughput. -Facilitate network growth. Core Layer Technologies Technologies used at the core layer include the following: – Routers or multilayer switches that combine routing and switching in the same device -Redundancy and load balancing – High-speed and aggregate links II. III. 4. DISTRIBUTION LAYERThe distribution layer is sometimes referred to as the workgroup layer and is the major communication point between the access layer and the core. The primary function of the distribution layer is to provide routing, filtering, and WAN access and to determine how packets can access the core, if needed. The distribution layer must determine the fastest way that network service requests are handled; for example, how a file request is forwarded to a server. After the distribution layer determines the best pat h, it forwards the request to the core layer. The core layer then quickly transports the request to the correct service.II. III. 5. ACCESS LAYER The access layer controls user and workgroup access to internetwork resources. The access layer is sometimes referred to as the desktop layer. The network resources most users need will be available locally. The distribution layer handles any traffic for remote services. INTERNSHIP REPORT The following are some of the functions to be included at the access layer: ? ? ? 17 Technologies such as DDR and Ethernet switching are frequently seen in the access layer. Static routing is seen here as well. As already noted, three separate levels does not imply three separate routers.It could be fewer, or it could be more. Remember, this is a layered approach. II. IV. NETWORK DESIGN CONCEPT My second part of my internship dealt with network design concept. In this I have been able to read different theories of network design from eBooks downloaded from the internet, doing exercises on subnetting, VLSM and VLANs and finally I had opportunity to do some practices on network documentation and laboratories on virtual LAN. II. IV. 1. THEORIES ON NETWORK DESIGN Designing a network for a better performance of data access and resource sharing of any institution is an extremely important thing to consider.I learned different concept of designing a network whether by reading eBooks or discussing it with my supervisor. A good network design is composed of four parts in general: Continued access control and policies Creation of separate collision domains Workgroup connectivity into the distribution layer through layer 2 switching Identification of customer’s needs and goals: In this part you deal with identifying business goals and technical requirements which include the task of characterizing the existing network, analysis of the network traffic. Logical network design: Here, it’s all about developing a network topology.Durin g this phase, you devise a network layer addressing model, and selects switching and routing protocols. It also includes security planning, network management design. Finally you make a study of the service provider on how he can meet your WAN and remote access requirements Physical network design: The physical design phase deals with specific technologies and products to realize the logical design. It starts with the selection of technologies and devices for campus networks that includes cabling, Ethernet switches, wireless access points, wireless bridges, and routers.There is also a selection of technologies and devices for remote-access and WAN needs. INTERNSHIP REPORT Testing, Optimizing and Documentation: The final step is to write and implement a test plan, build a prototype or pilot, optimize the network design, and document your work with a network design proposal. If your test results indicate any performance problems, then during this phase you have to update your design t o include such optimization features. 18 In all this different network design steps, I have been able to do some practices on logical network design where I did exercises on subnetting, VLAN as network management requires it.II. IV. 2. OVERVIEW VIRTUAL LOCAL AREA NETWORK (VLAN) Definition A VLAN (Virtual Local Network) is a logically separate IP subnetwork. VLANs allow multiple IP networks and subnets to exist on the same-switched network. A VLAN is a logical broadcast domain that can span multiple physical LAN segments. It allows an administrator to group together stations by logical function. A VLAN has three major functions: i. Limits the size of broadcast domains ii. Improves network performance ii. Provides a level of securitySecurity – Security of sensitive data are separated from the rest of the network, decreasing the chances of confidential information breaches. Advantages of VLAN: Higher performance – Division of Layer 2 networks into multiple logical workgro ups (broadcast domains) reduces unnecessary traffic on the network and boosts performance. Cost reduction – Cost savings result from less need for expensive network upgrades and more on this network. Types of VLAN There are different types of VLANs. The type of network traffic they carry defines a particular type of VLAN and others INTERNSHIP REPORT 9 names due to the type or a specific function the VLAN performs. The following describes common VLAN: Default VLAN At the initial boot up of the switch, All switch ports become a member of the default VLAN, which makes them all part of the same broadcast domain. This allows any network device connected to any of the switch port to communicate with other devices on other switch ports. On Cisco switches the default VLAN is VLAN 1. VLAN 1 has all the features of any VLAN, except that you cannot rename or delete it. Data VLAN A data VLAN that can also be referred to as user VLAN.This is configured to carry only usergenerated traffic. The importance of separating user data from other type of VLAN is proper switch management and control. Native VLAN A native VLAN is assigned to trunk port. An trunk port supports traffic coming from many VLANs as well as traffic that do not come from a VLAN. The trunk port places untagged traffic (traffic that does not come from a VLAN) on the native VLAN. In summary, the native VLAN observes and identifies traffic coming from each end of a trunk link. Management VLAN A management VLAN is any VLAN you configure to access the management capabilities of a switch.Your configured management VLAN is to be assign with an IP address and subnet mask. Any of a switch VLAN could be configured as the management VLAN if you has not configured or define a unique VLAN to serve as the management VLAN. In some cases, a network administrator proactively defines VLAN 1 as the management VLAN; this enables a loophole for an unauthorized connection to a switch. Voice VLAN Voice VLAN is configured to carry voice traffic. Voice VLANs are mostly given transmission priority over other types of network traffic. Communication over the network is not complete without phone calls.More calls are made over the network than other forms of a message transmission. Sending emails and text messages are also forms of inter-relations but listening to a real voice provides legitimacy and assurance. SOME EXAMPLE OF VLAN INTERNSHIP REPORT There I was design a network that are composed with 1 router ,2 switch ,6machine. 20 And each switch have 3 computer . one switch to three machine . on the network we have default vlan ,native vlan ,management vlan. Management vlan can control other machine on network. this network have the vlan and trunk . e have design it by using a outils that called packet tracer FIGURE 4: DESIGN OF A NETWORK Example of same machine i ping Machine ip 196. 168. 40. 105 are pinging a switch3 ip address 196. 168. 40. 106 INTERNSHIP REPORT 21 FIGURE 5 : Command Prompt INTERNSHIP REPORT 22 II. IV. 3. ROUTER PASSWORD RECOVERY 1. Connect the router to the PC using a console cable/port. 2. Open an emulation software (Hyper Terminal or Terra Term or Secure CRT, Putty) + setup (Com port and bits=9600, etc. ) 3. Switch on the router HOLDING DOWN CTRL + BREAK (keys) a. The router will boot and display the ROMMON prompt (Rommon;) 4.Type the CONFREG command to view current status 5. Change the configuration register (this is a hexadecimal number that tells the IOS where to fetch the configuration file. 0x142 bypasses the NVRAM contents, 0x2102 gets the configuration file from the NVRAM) a. Rommon;confreg 0x142 b. Reset (reboot i. e. power-cycle the router) The router will boot in normal but asking for a new configuration. 6. Router; (after saying NO to the configuration wizard) 7. Go to privilege mode (enable) and copy the startup-config to the running-config (Router#copy startup-config running-config).This will load the configuration with an unkown password back to RAM). 8. As you are already in privilege, the unkown password won’t prevent you from changing the configuration. You can now change the privilege password (LAB#config t ; LAB(config)#enable secret cisco). Also change the console and vty passwords. 9. Change the configuration register back to 0x2102 (LAB(config)# config-register 0x2102) then reload (in privilege mode). 10. Save your configuration.

Research Paper - Essay Example The monism argues that the body and the mind make one physical being. This is the basis of this research project. Dualists assert that human beings are a combination of two different units, the mind and the body. Dualists claim that the body and the mind are not connected and therefore, do not influence the working of each other. Dualists argue that after the death, the mind continues to existing on its own but in incorporeal form while the body putrefies or decays (Wingerter, 2011). One such dualist is Rene Descartes, who is one of the most modern philosophers. He believes that the body an the mind are two distinct elements. He formulated the Cartesian dualism theory that was named after him. The theory was put on the method and the meditation. Descartes, in the Cartesian dualism, claims that a human being is made up of two different elements: the body and the mind. This has been used as a proof why the mind has no immortality. Descartes argue that a human being is totally discrete and different to their material body. Descartes believed that the powers of human reason, a faculty of the mind, is the sole basis of knowledge. According to him, faculties of reason through intuition and deduction are natural characteristics of the human mind. Descartes also argues that the body is similar to a machine that is maneuvered by mechanical schemes, and that the mind has nothing to do with the processes underwent by the physical body. Mind and body and not connected to each other, just like the oyster has no connection with the pearl. To further this, Descartes believes that animals are just â€Å"automata† and act without the use of mind or consciousness, and are merely driven by mechanical schemes. This mechanical scheme, as discussed by Descartes, furthers the reasoning that the mind is totally independent of the body. Descartes claims that the brain controls the body mechanically by sending fluids through the neurotransmitters of the brain. This analogy reduce s the brain and the body to pure mechanical objects and puts into context that the it is possible for the mind to exist without the body, and the body to exist without the mind. He states that while the body is a non-thinking, extended thing, the mind is the complete opposite as it is a thinking, non-extended thing. Descartes has also given more evidence to prove that the body and mind are two different and disconnected elements but working in partnership. He argues that the body is by itself dividable while the mind does not have such divisible capability. â€Å"There is a great difference between the mind and the body in as much as the body is by its very nature always divisible, while the mind is utterly indivisible† (First meditation). This was the case in the transplantation of organs. If a person was to receive a heart from another person, where the heart is considered as the key organ for a human being’s body existence, the person does not become a new different person because of this. Transplantation shows how the body can be divided into different parts due to donation of body organs. Descartes argues that a person is made of different molecular structures, a variety of fluids, numerous nerves and body networks. Conversely, if a person dies, we are unable to form a construction of their mind. We cannot detach their thoughts into one part and their personality into another part. This shows therefore, that the mind is not dividable. Critics of this view

The Atlantic Economys Contribution to the Industrial Revolution Essay

The Atlantic Economys Contribution to the Industrial Revolution - Essay Example In addition, the bullion trade with the Americas created a concentration of capital that allowed for the economies of scale required for the promotion of the specialization of labor and large-scale investments. While all these components contributed to the Industrial Revolution, they were in fact small contributions that hastened and enforced the Revolution, but were not the primary cause. Transportation was instrumental in stimulating trade in the centuries before the Industrial Revolution, but may of made only small contributions to the overall economy. Bristol, during the 17th century was the central hub for the voyage to the Americas. While by 1630 there were relatively few vessels making the trans-Atlantic crossing to the American plantations, by the turn of the 18th century this number would swell to over half of the vessels leaving the port (Sacks). These ships were bound for Virginia, the West Indies, or Newfoundland, and by 1700 commercial American sugar and tobacco had become a trading staple (Sacks). Certainly trade was important for Britain during this period for raw materials as well as exports of goods to the slave driven plantation system. However, even as late as 1790, after the Industrial Revolution was well under way, the Americas only accounted for 18% of European exports, while exports to Africa to support the slave trade amounted to only 1% (O'Bri en, 4). The real growth in trade would not take place until the 1840s when Clipper Ships were able to make more voyages and handle more fragile cargo (Jones). Trade and transportation to the Americas may have contributed to the growing export market, but was not a major cause for the Industrial Revolution. While the export market had only a marginal effect, the importation of agricultural products may have been even less significant. The agricultural processes necessary to support a growing urban population had been in effect well before the discovery of the Americas. In addition, raw materials needed to sustain long-term production and growth were already available in Europe. According to O'Brien, sugar and cotton had been transplanted to Italy, Iberia, and Southern France prior to 1492 (11). The introduction of maize from the Americas would have no substantial impact on the English diet until the middle 19th century after the Industrial Revolution had been under way for some decades (O'Brien, 11). More important to the Industrial Revolution than raw materials was the mercantilist system of protections and the reservation of the final processing into finished goods (Darity, 165). This assured that capital would continue to flow into Europe. Raw materials and the foodstuffs necessary t o sustain the factory system and an exploding population were all available outside the Atlantic economy well before the Industrial Revolution. The formulation of the Industrial Revolution demanded a ready supply of capital for investment. Bullion from the Americas created a hard international currency, but it was not been instrumental in developing concentrated capital.

Controlling Child Pornography on the Usenet Article

Controlling Child Pornography on the Usenet - Article Example So it is easily understandable that anonymity serves as the key for such criminals, which they feasibly use as a protective shell. The catch-22 is that the complete censorship of CP on Usenet cannot be implemented easily since that is somewhat impossible without banning the internet because Usenet is basically served by the internet. And why just strike out a war against Usenet when the percentage of CP on the internet is basically even larger? The cutting truth is, pornography can never be simply rooted out and finished forever since it really grows vigorously. Amidst darkness, the scintillating hope is that lately many Usenet communities have been reported to be curbed after important measures observed at the Government level. Internet Service Providers have been forced to shut down Usenet access at many places in order to cut down the incessant demand of child porn. Cuomo crackdown is a well known open war happening against the erotic newsgroups of Usenet. â€Å"NY State attorney Andrew Cuomo has managed to get two more ISPs to join his ‘Crusade’ against Usenet child porn.† (Roettgers, 2008). America Online is among the ISPs who have agreed to do something about blocking CP and once it denies access to newsgroup servers, the Usenet is sure to become a less attractive magnet for cybercriminals. Another fact supporting the rampage against Usenet is that Recording Industry Association of America sued Usenet for trillions of dollars, criticizing it as the network of illicit file sharing sites. Still saying that cyber censo rship alone can play a vital role in stemming down CP is not actually true, since a large number of new Usenet groups and web servers are created daily.

Paradise Now and Then Essay Example for Free

Paradise Now and Then Essay Understanding who the characters were and the reasoning for their actions was missing. Learning on how and why they started fighting was a challenge faced while watching this film. The lack of seeing relationships form and how the fighting started was a major difference compared to Paradise Now and then. During this ninety-minute production it was very clear on the relationships the characters held with one another. The roles each character played were easily connected back to the plot and helped unfold later scenes because of the apparent character attitude due to the time span of the film. The tactical plans behind the film’s attacks are showcased in very different ways. In The Battle of Algiers that attacks don’t show any planning before the actual attacks. The attacks on the street all just occur without planning. The attack upon the Palestinians is all of a car ride over to their community and a bomb explodes the building. The third attack from the Palestinians is all of three women changing their appearance to cross the border and the man creating the bomb. All that is left is the execution. Within Paradise Now and then the planning initially started nearly ten minutes into the film and wasn’t executed until eighty minutes later at the end. Since this plot takes so long to actually play out, it shows the emotions of the characters as to how they feel about their assignment. This also helps grasp an emotional level with Said and Khaled. Watching them go through the process and make decisions contributes to understanding of their different personalities. The Battle of Algiers, is a continuous strike to one side, then a counterattack from the other side. An in depth reason as to how the battle was started, the tactics behind the different attacks, and why specific person(s) were responsible for performing the attack was unclear because of the short time span. The music in The Battle of Algiers helped lead the viewer to certain feelings in various scenes. During the first attack scene from the Palestinians the music was dark and evil. This music type didn’t support the attacks of the Palestinians and seemed to take the other side. But when the Palestinians were attacked, the music was sad and remorseful suggesting feeling bad for the victims and their loss. The same music type took place while the French colonists bombed the Palestinian building. The music was dark and evil but when the French were bombed, the music was depressing and gloomy. Within the twenty-six minutes the film never chose protagonists and antagonists. The setting of the films played a big role on what the sides were actually fighting for. In the beginning of Paradise Now and then, while Said and Khaled are smoking they are sitting upon a hill. The camera is set from behind them looking down over their town suggestion they have power and control. This is showing whom they would be fighting for and the mass number of people who would be affected. Said crosses the border and walks along a highway of huge open land. Also Said and Khaled walk downtown together through towering buildings. The two scenes suggest the size of the opponent. In The Battle of Algiers, all of the scenes occur in the small streets of France and it appears as if the battle is being fought within one community. The camera is taking the view of a character on the street during the battles suggestion that neither side has power over the other. While one story crosses the street to fight for their people, the other crosses the border. Film making decisions can very easily pull in a viewer to the themes and motives of a plot. In The Battle of Algiers, the viewer does not get pulled into the battle. The film lacks the interest of one side over another and without this choosing of a protagonist verse an antagonist, the viewer cannot feel emotionally tied into the battle. Also without being introduced to any characters, the viewer in unclear to who is really being put at risk with each attack, who is gaining or losing what from the attacks, and what is actually being gained or lost. The only influence on the attacks that the viewer is aware of is that one side attacked another, so they must strike back. The filmmaking decisions do not shape the viewers attitude toward any character in this film. In Paradise Now and then, the viewer follows Said and Khaled through their journey to supposedly the end of their lives. The viewer is able to feel why the characters choose to go along with their mission, what is at stake if the mission is attempted, and what will be gained and lost if the mission is successful. Religion is a big factor that influences Said and Khaled to become suicide bombers. Khaled asks, â€Å"What happens after death? † He gets an answer of â€Å"Two angels will pick you up. † This is very satisfying for Khaled and Said to hear. Remarks are often made throughout the film regarding God. That they are doing their people and God a favor. Also â€Å"We do what we have to, God decides the rest. † At first they know what they will do will affect their people and help solve this fight, but then when Khaled talks to Suha, she talks him out of the bombing telling him that maybe if they don’t strike back that Israel will back off. The viewer is drawn to the fact that Khaled and Said are not fighting for violence or to kill, they are fighting for their people and God. The camera work while Said is talking about his father helps the viewer feel sympathetic for his loss of his father. The camera slowly zooms in on Said as he describes his father and this captures the viewer’s attention and pulls the viewer in as if Said is talking directly to the viewer. The viewer is also influenced to want Said and Suha together. Suha is only around when she is with Said. After the first scene Khaled tells Said that he thinks Suha likes him. After that the viewer is drawn to believe there is a connection between the two. This affects the later scene when Suha tries to influence Said not to fight because now the viewer is torn between having Said sacrifice himself for his people and God, or wanting Suha and Said to be together. Suha’s last appearance is while she is siting down at her table gazing at a picture of Said. The films do not showcase the political issues at stake in the historical situations. In the stories, all that is at stake within the plots are peoples’ lives. Whether it is a shooting on the street or a suicide bombing across the boarder, which kills the bomber and the victim. No other issue takes a bigger role in these two plots that the loss of peoples’ lives. It does seem correct as Suha said; if the opposing side doesn’t have a reason to strike back, the fighting will stop. The two films are stories of bombings between two different sides but are introduced through different means of filmmaking decisions. These different tactics shape the viewer’ attitude towards the bombing itself and the characters within the plot. In The Battle of Algiers, the viewer is influenced to oppose fighting due to one strategy, which is music choice. In Paradise Now and then, the viewer is influenced by the will to fight, which is an example of setting. Both films are stories about bombing but draw the audience into the plot with different tactics and strategies.
