What is a network protocol?
Network protocol same as human protocol. Human protocol means something we conduct all the time. Examples are render greetings, wait for a response, analyze the response, and act according to it. Why the network protocol similar to human protocol. Because network protocol also conducts the above-mentioned human protocol functions on the internet. Obviously, network protocols conduct, manage, and govern all communication activities in the network. A network protocol declares as rules which allow for data transmission between network devices. On the other hand, it conducts the format of messages so they can exchange successfully.
Definition of network protocol
What is a network? A network can build by connecting two or more computers. A network intends to enable the transferring information and files between multiple computer systems. Two computers should follow a set of rules when sending and receiving information with each other. In order to that, an essential set of communication rules called protocol rules which conduct the communication between two computers connected to the network. The computer network contains many different protocols. As well as they help to carry data packets. The protocols are built to work on different levels of network layers.
Types of network protocols
There are many network protocols in different network layers. There are mainly four different network layers and it has its network protocols. HTTP which is a most popular network protocol, FTP (File Transfer Protocol), SMTP, and DNS are some protocols in the Application Layer. As well as Transport Layer consists of TCP and UDP protocols. Furthermore, IP (Internet Protocol), ARP, ICMP, and IGMP are Network Layer’s protocols. Finally, Ethernet, Token Ring, and other link-layer protocols include the Network interface Layer. Out of that HTTP, TCP/UDP, IP is the most popular network protocols.
HTTP (HyperText Transfer Protocol)
Also, HTTP considered a web browser. Hypertext refers to the text on a computer that will lead the user to other, related information on demand. Hypertext documents create using a special kind of document formatting or “markup” language called HyperText Markup Language (HTML). HTML format documents send or received between two or more computers over the network using HyperText Transfer Protocol (HTTP).
TCP means Transmission Control Protocol. TCP is connection-oriented. Along with configuration should be done between client and server processes. This is a full-featured protocol and allows us to transfer data and information reliably without considering network layer problems. However low overhead but it is higher than UDP. Transmission is speed is high but not speed as UDP. Because it has more additional functionalities. Also, it can transfer small to very large data quantity via the network. As well as TCP is sequenced and has acknowledgments.
UDP defines as User Datagram Protocol. This is non-sequenced as well as it has no acknowledgment. It does not worry about the order of packet arrival. UDP needs fewer computer resources. Indeed, it has very high-speed data transmission than TCP because it has not additional features to do. Nevertheless, this network protocol is unreliable and connection-less. On the other hand, it has low overhead and low functionality.
The extraction name is Internet Protocol. Actually, the internet is a network of computer networks. Here data is transmitted by packet switching using the standard Internet Protocol (IP). A packet defines as a unit of delivering packets from one computer device to another. Importantly, basic task or functionality of IP is transferring data packets as quickly as possible from one router to another.
