Computer networks: please answer the question correctly ATM is a link layer technology that uses a short packet, called an ATM cell, with a total length of 53 bytes. Find the ATM protocol efficiency (in %) if the cell header is 5 bytes. Use only one digit after the decimal point.

Transmittal protocols There are advantages and disadvantages to using both TCP and UPD in the current state of network design.

The transport layer protocols The challenges that inevitably come from the use of TCP and UPD in modern networks

Repeaters are often used on an 802.3 network to help strengthen the signals being transmitted. As with the length of segments and the number of segments, a limit exists as to how many repeaters can be used between any two nodes. What is the maximum number of repeaters that can be used? a. 1 b. 4 c. 9 d. 12

In the context of computer networking, explain the differences between fiber optic and copper Ethernet cables, considering factors like speed, distance, and susceptibility to interference.

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.

In the context of cable standards, delve into the differences between TIA/EIA-568A and TIA/EIA-568B wiring schemes for Ethernet cables. When would you use one over the other?

computer network: Draw a structural diagram of IEEE 802 standard chart. Also, illustrate in detail IEEE 802.1-802.16 standard

Explain the concept of OSI model and the seven layers of network protocols.

When you send a particular packet of information across a network, it needs to be routed from the sender to the intended receiver. (a) Explain how information is communicated over a network, including mentioning the equipment you need to direct the information. (b) Outline different cabled approaches you could use to create an ethernet network. (c) Draw a schematic of a local area network that can connect 10 users to 100Gbps data rates, mentioning the equipment you would use.
