HDLC (High-level Data Link Control) is a group of protocols or rules for transmitting data between network end points. In more technical terms, HDLC is a bit-oriented, synchronous data link layer protocol created by ISO. In your report discuss the following: introduction about HDLC, types of stations, mode operation, frame formats, HDLC flow control and OSI layer for HDLC.

Describe the basic operation of ARP (Address Resolution Protocol) and its role in local network communication.

Could you maybe provide a more in-depth explanation of each of the four components that make up the IEEE 802.11 architecture so that I can have a better grasp on how it works?

If 10 devices are added to each network constructed with a star, mesh, ring, or bus topology, what modifications would be required to each topology, and which of these topologies requires the most and least changes?

Synchronous Optical Network (SONET) is high speed communication protocol which is used to transmit a large amount of data. It is a standard for synchronous data transmission on optical fibers.Based on the description given above, ELABORATE your answer from the questions below:a) Briefly EXPLAIN the SONET protocol with its network elements. b) ANALYSE the interrelation between SONET and ATM.

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)

Explain the concepts of NAT (Network Address Translation) and PAT (Port Address Translation) in detail, along with their use cases in modern network configurations.

[ ] As the data packet moves from the lower to the upper  layers, headers are added. [ ] Every network device implements the transport layer.  [ ] In the Ring topology, each computer acts as repeater make error detection and boosts the signal before sending it on. [ ] In bus topology network media is inexpensive and easy to work with, so it is easier to trouble shoot than other topology. [ ] Error control only detects errors [ ] Ethernet is a LAN so it is placed in the second layer of the OSI reference model. [ ] UDP provides connectionless service and delivers packets quickly. In case of packet loss, UDP does not provide retransmission. [ ] UDP is the preferred over TCP for transferring a real-time voice over IP networks. [ ] In a bus topology, each station on the network is connected to two other stations, forming a loop or ring. [ ] IEEE international Telecommunication Union for creating protocols of internet. [       ] TCP protocol is slower than UDP?

How does a bridge function in the OSI model, and which layer does it primarily operate in?

Write an essay on ODVA implementations. Your Essay should have at least four (4) pages (double spaced) and should briefly describe each of the four (4) data link infrastructures over which CIP can operate, and include a table where you compare each data link protocol with a set of at least 5 characteristics (compatibilities with IOT, message size, cost of minimal implementation, etc.) and mark which characteristics is/are present on each infrastructure for CIP. Comment on why these DL infrastructure alternatives.

Question 1: True or False: [ F ] Telephone network is an example of Packet Switching network. [ F ] It is the network layer’s responsibility to forward packets reliably from the source to the destination [. T ] Flow control is required to assure that the source does not overwhelm the destination by sending data faster than they can be processed and absorbed. [ ] The key elements of a Protocol are syntax, semantics, and error control [ ] User Datagram Protocol (UDP) can guarantee data delivery. [ ] Routing decision is always required for every packet of a message at each node in packet switched network. [ ] In OSI model data link layer provides for the reliable transfer of information across the physical link; sends blocks (frames) with the necessary synchronization, error control, and flow control. [ ] The transport layer is responsible for hop-by-hop communication. [ ] Because the boundaries between layer are well defined change in standard in one layer effect  already existing…
