Network protocols
Definition of protocol
Network protocols are a set of rules that make communication between devices more successful and ensure that messages are exchanged.
A set of protocols share the communication process, working with each other to ensure that the message is received and understood by both parties. Here are examples of these protocols:
Application Protocol
Hypertext Transfer Protocol (HTTP) is a commonly used protocol that controls the way a Web server and Web client interact. The HTTP protocol determines the content of requests and mutual answers between client and server and their formats.
The client and Web server programs together implement HTTP as part of the application, and HTTP relies on other protocols to control how messages are transferred between the client and the server.
Transport Protocol
Transmission Control Protocol (TCP) is the transport protocol that manages individual conversations between Web servers and Web clients. The TCP protocol divides HTTP messages into small pieces, called sections.
The sections are sent between the Web server and the client processes that are running in the destination host. TCP is also responsible for controlling the volume of messages exchanged between the server and the client as well as the exchange rate.
Internet protocol
An IP address is responsible for taking TCP-formatted segments, including them in packages, allocating appropriate addresses, and connecting them through the best path to the host.
Network Access Protocols
Network access protocols describe two basic functions, data link connections and the physical transfer of data over network media.
Data Link Management (DRM) protocols obtain and format the IP packet to be transmitted over media.
Physical media standards and their protocols control how signals are transmitted over media and how client clients translate them. Ethernet is an example of a network access protocol.
Standards for the manufacture of protocols
As explained earlier, the protocols work together to provide comprehensive network communications services. A set of protocols can be identified by a standards organization or developed by a distributor.
The IP, HTTP, and DHCP protocols are all parts of the Internet Protocol (IP) protocol known as TCP / IP.
TCP / IP is an open standard, which means that these protocols are available free of charge to the public, and any distributor can implement these protocols on their own devices or programs.
A standards-based protocol is a process or protocol that has been certified by the network sector and approved or approved by a standards institution. The use of standards in the development and application of protocols will ensure that products from different manufacturers work together successfully. If the protocols are not strictly monitored by a particular manufacturer, their devices or programs may not communicate successfully with products produced by another manufacturer.
In data communications, for example, if one end of the conversation uses a protocol to control the one-way communication and the other party uses a protocol describing a bidirectional connection, no data will be exchanged for all possibilities.
Some protocols are proprietary. In this context, private ownership means that a single company or vendor controls the definition of the protocol and how it works. Some proprietary protocols can be used by different institutions with permission from the owner. While other protocols can be applied to devices that have been manufactured by a private property vendor.
