2. Type the following paragraph correctly in a new word document file (.docx). What is Network The network used to interconnect computers in a single room, rooms inside a building or buildings are normally called local area networks (LANs). LANs normally transmit data in a digital form using media such as coaxial cable or multithreaded cable. Local Area Network can be used only on one side of a building. The terminals and workstations can connect either one of the 'two' host computers when required. The network has a file server and a print server. The file server is a special computer that provides a form of auxiliary storage that can be used by any other computer on the network. The print server is a special printer that can receive data from other computers on the network and print it. It is possible to connect external communications server on the LAN with a device which makes the communication possible between the equipment of the network and system elsewhere, e.g. modem. For…

Problem Solving. Category5 cable, commonly referred to as CAT-5, is a twisted pair cable for data networks. Since 2001, the variant commonly in use is the Category5e specification (CAT-5e). The cable standard provides performance of up to 100MHz and is suitable for most varieties of Ethernet over twisted pair up to 1000BASE-T(Gigabit Ethernet). We would like to transmit information over a CAT-5 twisted pair cable at 500 Mbps. (a)What is the signal-to-noise ratio (SNR) of 30 dB adequate to transmit 500 Mbps?  (Convert the SNR of 30 dB to a numerical value then apply the Shannon Theorem). (b) What is the SNR required to just adequately transmit at 500 Mbps?  Express your answer in decibels for the SNR(that is, SNRdB)

Coaxial cable has been around since local area networking was in its invented. The original designers of Ethernet picked coaxial cable as their "ether" because the coaxial cable is well it has high bandwidth capabilities and low and is easy to install. Coaxial cables are identified by their RG standard. Coaxial cable can have a or stranded core and impedance of 50, 75, or 92 ohms. The Coaxial has wire that carries the signal surrounded by a layer of and another concentric ; both the shield and the inner conductor run along the same axis. The shield also serves as a ground and should be grounded to be effective. Coaxial cable is still widely used for video applications; in fact, its use is increasing due to the greater demand for However, it is not recommended for data installations and is not recognized by the Standard for such.

) With the aid of well labelled diagrams, design a network system using a combination(at least two) of any of the network topologies. Consider the following: i. Choose a Network Address for you network systemii. Base on your Network Address, assign IP addresses to the devices in your network.There should be a Server, a Switch and a Router in your network. AP (7)4NB: Discuss the design of your network as part of the answer to this question in your answer booklet. The discussion should include the type of topology used, the Network Address used, the class of IP address and the general concept of your choice of design.

SDN is an acronym that stands for "software-defined networking," and it refers to a collection of standards for digital transmission via conventional copper wire telephone lines, in addition to other forms of media.a. CCITT b. ITU c. Both a and b and d. None of the options presented.None of the things listed above

Part II:    In ADSL service, there is a single UTP pair running from the end office switch to the individual household. In cable modem service, the thick coaxial cable in the neighborhood is shared by many subscribers. Yet typically, cable modem service provides faster service to individual customers than ADSL. How can this be?

PROJECT 2 - Data Transfer Efficiency A packet consists of a header and a payload. The header is fixed at 20 bytes. The range of the user data to be transferred over the network is from 64 bytes to 1518 bytes with an increment of 1 byte, i.e., 64, 65, 66, ..., 1518. Plot transfer efficiency vs size of user data (y-axis is efficiency, x-axis is size of user data) on three different plots corresponding to these cases: (a) Maximum packet size = 100 bytes (b) Maximum packet size = 500 bytes (c) Maximum packet size = 2000 bytes Clearly label the axes and the ranges. What can you conclude looking at those three plots? You may use Excel or your favorite programming language to generate the plots. Submit the following on Canvas: The plots AND the answer to the above question in PDF format. • Your code.

SUBJECT : COMPUTER NETWORKING (PLEASE PROVIDE COMPLETE RELEVANT SOLUTION) One important issue in networking is the performance of the network. The question is how can measure the performance of heterogeneous networks. For example, UIIT  University network which provides access to students at both wired and wireless networks. In this kind of scenario: You may need to define key performance parameters that can be used to evaluate the network performance.  If UIIT has a total bandwidth of 100Mbps and 40Mbps is reserved for admin and faculty. Due to COVID-19 pandemic total students coming daily altogether in morning and evening are 500. How much bandwidth a student can achieve if all students are using internet at the same time?

In Figure Z, S1 connects to Computer A with an Ethernet Cable. In the older days, you needed to be very specific regarding the Ethernet Cable that should connect from S1 to Computer A. (Hint: We are talking about Straight through vs. Crossover Cables.) What type of cable should be used to connect S1 and A? What about the cable connecting S1 and R1? What if R1 is directly connected to Computer A (without the switch). What about two computers connecting to each other directly through an Ethernet Cable? why do we not need to worry about whether the cable is Straight through or Crossover Cable when connecting devices these days?
