Network communications protocols are a way to send data between two systems. They define rules for syntax, semantics, synchronization, and error recovery. There are numerous protocols that are used in communication, from HTTP to ICMP. Let’s look at some of them. Then, learn about their advantages and disadvantages.
TCP/IP is a network communication protocol that divides a single message into several packets. These packets can then be forwarded by network devices such as routers and switches. Each packet is numbered so that it can be routed to its destination. This type of protocol is connection-oriented, which means that it ensures that a link is formed between the source and destination computers.
HTTP is a standard for web-based computer communications. It uses ASCII text format to specify the request and response. It defines three basic methods, GET, PUT, and DELETE, which are all derived from the name of the resource. The GET method is the most commonly used. This method asks for a specific resource that corresponds to an existing or dynamic file on the server. The POST method, on the other hand, uses an entity body, which is the user’s input.
FTP is a network communications protocol used to exchange files between computers. It uses a control connection to transmit data and responds to commands from the client. The protocol can be used with binary or text files and uses a variety of different transmission modes. In the default mode, data is transformed into a stream of …View More Network Communications Protocols
