Communication protocols enable information to be sent or received from any location. Different types of protocols serve different purposes. Some protocols are used to protect networks, while others serve a convenience purpose. 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. Another common protocol is SMS, which is used to send text messages via cellular networks. While SMS is useful for sending text-based messages, it doesn't support pictures and videos. Multimedia Messaging System (MMS), which is an extension to SMS, can be used for these types of messages.
Functions
Communication protocols provide functions that allow the transfer of data between two devices. They can be used to manage data traffic and include data flow control, addressing, and sync. Each of these processes ensures that data arrives at its intended destination in the proper order. Other functions are also performed by some protocols, such as providing data flow control.
A protocol specifies what data is to be transmitted and how to transmit it. Protocols are similar to languages. They contain rules that regulate the meaning of data. These rules are also called the syntax and semantics in communications. They can be defined in formal ways.
Layers
In communication protocols layers refers to the various components of a network. Each layer can be responsible for different types or functions. The network layer handles addresses while the physical layer handles physical media. Rules govern the transmission of data through networks, both at the physical and logical levels.
A protocol can generally be broken into multiple layers and then organized by functionalities. Each layer solves a particular problem. These layers allow messages to be sent by selecting one protocol and adding a protocol selector.
Security
One of the most critical branches of cybersecurity is network security. Communication protocols play an important role in protecting network resource. Increased cybercrime has resulted in the proliferation of computer network, protocols are essential to ensure that networks remain secure. Protocols control how data is moved within and between networks, protecting it.
Modern internet security protocols protect against malicious activity and keep communications private. They include anti-spyware and antivirus software. Some programs also filter the contents of web pages and identify common annoyances. All these security features are part of secure communication.
Interoperability
It is common to use communication protocols to link two computers. It is necessary to observe the behavior of IUTs in order to determine if they are interoperable. There have been many approaches to testing the interoperability among communication protocols. One method is the test derivation approach. This technique allows test case generation to be done automatically.
The process of ensuring interoperability between two computer systems is known as conformance testing. Conformance testing compares the implementations of two communication networks against standardized protocol specifications. This is an effective way to ensure interoperability but it comes with its limitations. Two different conformant implementations could still not communicate. There are three main reasons this may happen: ambiguity with protocol standards, incompatible choice settings, and incomplete conformance tests.
