Communication protocols provide an avenue through which information can be sent and received from one location to another. Different protocols serve different purposes. Some are used for security reasons, while others are used for convenience. SSH, for example, is used to protect computers connected to an unsecure network. It is also useful for network administrators who want to remotely control a system. SMS, which allows users to send SMS via cellular networks, is another common protocol. SMS is only useful for sending text messages. It doesn't allow you to upload pictures or videos. Multimedia Messaging Software (MMS), an extension to SMS, is required in order to send these types message.
Functions
Protocols allow data to be transferred between two devices. They offer a variety of techniques for managing data traffic including data flow control, address, and synchronization. Each process helps to ensure data arrives at the intended recipient in the correct order. Other functions may also be performed by protocols, including limiting the flow of data.
A protocol specifies the type of data to be transmitted, as well as the commands to transmit and receive data. Protocols are similar to languages. They contain rules that regulate the meaning of data. These rules are known as the syntax and semantics of communications, and can be specified in formal ways.
Layers
Layers in communication protocols refer to the different parts of a network. Each layer performs different functions and can handle different types of data. For example, the network layer handles addresses, while that of the physical layer handles the physical medium. Both physical and logical layers have rules governing the way data can be transmitted through a network.
Generally, a single protocol can be divided into multiple layers, and these are then organized by functionalities. Each layer addresses a specific problem. Messages can be sent through these layers by selecting one protocol from each layer and adding a protocol selector to it.
Security
Network security is one of the most important branches of cybersecurity, and communication protocols play an essential role in protecting network resources. The rise in cybercrime is due to the proliferation and security of computer networks. Protocols are used to protect networks. Protocols are what control data movement within a network. This ensures that data is protected and secure.
Modern internet security protocols protect against malicious activity and keep communications private. These protocols include antivirus software, firewalls, and programs to neutralize spyware or adware. Some programs also filter the contents of web pages and identify common annoyances. All of these security features fall under the domain of secure communications.
Interoperability
Communication protocols are often used as a means of connecting two computers. It is necessary to observe the behavior of IUTs in order to determine if they are interoperable. To test the interoperability and usability of communication protocols, there are several approaches. One method is the test derivation approach. This method allows test cases can be generated automatically.
Conformance testing refers to the process of verifying interoperability among two computers systems. Conformance testing is the process of comparing two communication systems' implementations against standard protocol specifications. Although this method can be used to ensure interoperability it has some limitations. Two conformant versions may not be able to communicate. There are three main reasons this may happen: ambiguity with protocol standards, incompatible choice settings, and incomplete conformance tests.

The goal of RWD is to ensure that when a user views a site on any screen size, they view the exact version of the site.
