- Assume that Computer A, which is connected through an Ethernet cable to the Switch S1, is just powered on. The user opens a browser and then types a website address to receive the website from the Server (as shown in Figure 1). Write down all the important protocols that come into play by the time the first frame containing HTTP request reaches R1. (Note: Before HTTP frame, other frames have already been sent by other protocol(s).) Write down all the protocols with reference to the TCP Model as follows?

- Computer Science Networks and should be done in C language. Create a UDP client and server program that not only is able to locally transfer files but it gives the client the ability to send multiple copies of the file to multiple servers. Once the server program is initiated, it waits until it receives client packets. It then reads and saves the payload of the packets. The client reads a file from the disk and sends it to each server over a UDP socket by breaking the file up into mtu-byte sized packets. Client needs to be concurrent in sending the packets to all of the servers using threads7.1 In IEEE 802.11, open system authentication is accomplished via a simple two-way communication. The client requests authentication, which includes the station ID, which is provided by the server (typically the MAC address). A successful or unsuccessful authentication response from the AP/router is received in response to the previous request from the client. For instance, if the client's MAC address has been expressly omitted from the AP/router setup, a failure may occur.a. What are the advantages of using this kind of authentication scheme?b. What are the security flaws in this authentication method and how may they be mitigated?Consider the scenario in which one computer sends a packet to another computer by using the transport layer of the Internet. No process using the destination port address is currently active on the machine that is the target. What exactly is going to take place here?
- For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.A. “Security is different in wireless” Discuss the statement above. The answer needs to take into account all aspects of the debate. Provide example if. Support your answer with reference. B. In IEEE 802.11, open system authentication simply consists of two communications. An authentication is requested by the client, which contains the station ID (typically the MAC address). This is followed by an authentication response from the AP/router containing a success or failure message. An example of when a failure may occur is if the client’s MAC address is explicitly excluded in the AP/router configuration. What are the benefits of this authentication scheme? What are the security vulnerabilities of this authentication scheme?In IEEE 802.11, two-way communication is used to authenticate an open system. In order to authenticate the client, the server must give the station ID (typically the MAC address). Response to the client's previous request is either a successful or failed authentication response from the access point/router. An error may arise if, for example, an AP/router configuration does not include the client's MAC address.In what ways is it advantageous to use this kind of authentication scheme?In what ways does this authentication technique have security vulnerabilities that might be mitigated?
