Communication protocols are a way to send and receive information from one place to another. Different types of protocols serve different purposes. Some protocols are used to protect networks, while others serve a convenience purpose. SSH, which is used to secure computers connected to an insecure network, can also be used by network administrators to remote control a system. SMS, which allows users to send SMS via cellular networks, is another common protocol. SMS is useful to send text-based message, but it does not support video or images. To send these types of messages, you must use Multimedia Messaging Service (MMS), an extension of SMS.
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 steps helps ensure that data arrives to its intended recipient in the right order. Some protocols also perform other functions, such as providing a service to limit the flow of data.
A protocol specifies what data is to be transmitted and how to transmit it. A protocol is similar to a language. It contains rules that control the meanings of data. These rules, also known as the syntax or semantics of communication, can be formalized.
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 deals only with addresses, while physical layers deal with physical mediums. 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 is designed to solve a specific class of problem. These layers allow messages to be sent by selecting one protocol and adding a protocol selector.
Security
Network security is a vital part of cybersecurity. Communication protocols play a crucial role in protecting network resources. Cybercrime has increased with the proliferation computer networks. Protocols can help to make sure that networks are as secure and protected as possible. Protocols are what control data movement within a network. This ensures that data is protected and secure.
Modern internet security protocols are designed for protection against malicious activities and to keep communications private. These protocols include antivirus software, firewalls, and programs to neutralize spyware or adware. A few programs filter the content of web pages to identify annoying issues. All these security features are part of secure communication.
Interoperability
To provide a link between two computers, communication protocols are used often. The behavior of IUTs can be used to verify interoperability. There are many ways to test interoperability between communication protocols. One method is the test derivation approach. This technique allows test cases to be generated automatically.
Conformance testing is the process of ensuring interoperability across two computer systems. Conformance testing involves comparing the implementations of two communication systems against standardized protocol specifications. This is an effective way to ensure interoperability but it comes with its limitations. Two conformant implementations may still fail to communicate. These problems can be caused by ambiguity or incompatible option settings, incomplete conformance testing, and protocol standards that are unclear.
