Computer Networking - Protocol - Essay Example

Computer Networking Computer Networking There are certain advantages of using circuit switching in computer networks. A significant advantage is that there is the possibility of putting data paths in a way that allows for connection that can be regarded as smooth. There is also a possibility of removing buffers that may be witnessed in the paths. In addition, this mode of network switching enhances the use of a higher capacity for switching. Despite the advantages of circuit switching, there are also some disadvantages that relate to this method of networking.

One such disadvantage includes inefficiency, which results from the fact that there is a guarantee of capacity in connections that may not be in use.Packet switching can be regarded as advantageous since it allows for the groping of all data under transmission. As such, data is grouped without consideration of its structure, or even the contents of the data. Packet switching also allows for the sharing of data networks among various users. Packet switching can be discredited because it is slower than other methods used in data transmission.

The advantage of Frame Relay is that it allows the connection between routers, as well as Local Area Networks. Frame relay can be regarded as disadvantageous since there is a lot of congestion between the networks. The use of Asynchronous Transfer Mode 2 can be regarded as beneficial based on a number of advantages that result from its use. ATM enhances the use of multimedia services within a single network since it facilitates the transmission of video and voice at the same time. ATM can also be regarded as useful since it allows ease of connection between Wide Area Networks and Local Area Networks (White, 20130.

The primary disadvantage of ATM is that it is costly; as such, it brings with it financial challenges to an organization. There is also a need to install new software and hardware to serve new customers. Transmission Control Protocol (TCP) can be regarded as the main language used in internet communication. The primary advantage of TCP is that it allows for ease of communication between servers in a computer network. TCP also allows for the resending of data packets that may be lost during the transmission of data.

In addition, there is order in the sending and receiving of data when TCP is used. The main disadvantage that can be attributed to this mode of data transmission is that slow transmission may be experienced (White, 2013).There are significant protocols in both packet switching and circuit switching. In packet switching, there is division of messages into packets before such messages are sent through the networks. The major protocols in packet switching include most WAN protocols, most of which entail Frame Relay, Internet Protocol, as well as X.25. On the other hand, circuit switching includes telephone conversations that can be regarded as normal.

The main protocols in this form of network switching include sending of data, which can be considered to have been sent in real time. Other protocols in this form of data transmission include web pages, which serve purposes such as email (White, 2013).References White, C. M. (2013).
