What is Protocol? What is TCP/IP, FTP, HTTP, GOPHER, TELNET, SMTP, ETHERNET?

Protocol Definition: 

It is a digital language through which we communicate with others on the Internet. Protocol meaning is that it a set of mutually accepted and implemented rules at both ends of the communications channel for the proper exchange of information.

Types of Protocols:-

TCP

Transmission control protocol is used for communication over a network. In TCP data is broken down into small packets and then sent to the destination. However, IP is making sure packets are transmitted to the right address.

Internet Protocol (IP)

IP is also working with TCP. It is an addressing Protocol. IP addresses packets route them and show different nodes and network Unless it reaches its right destination. The IP protocol is developed in 1970.

FTP

File transfer protocol is basically used for transferring files to different networks. There may be a mass of files such as text files, multimedia files, etc. This way of file transfer is quicker than other methods.

SMTP

Simple mail transfer protocol manages the transmission and outgoing mail over the internet.


HTTP


HTTP is based on client and server model. HTTP is used for making a connection between the web client and web server. HTTP shows information in web pages.

Ethernet

Ethernet is a most important for LAN communication. Ethernet transmits the data in digital packets. If any computer wants to use this protocol they should contain Ethernet Network Interface Card (NIC). The card is implemented with unique address code fixed in the microchip.

Telnet

Telnet is an established with some rules which are used to connect to another computer. Telnet is mainly used for the remote login process. The computer which is requesting for a connection that is a local computer and which is accepting the connection that is a remote computer. If you give a command in a local computer that command is executed in the remote computer. Telnet is also based on client and server model.

Gopher 

Gopher is an application layer protocol, which is used for searching and retrieving documents from remote sites. This is possible to start an online connection with other computers through gopher.

What is OSI Model in networking?

-

1.  OSI Model  stands for Open System interconnection model. 2.  OSI Model  defines how data is transferred from one computer to another computer. 3. In a very basic scenario two computers connected with a LAN and connectors transfer data using the NIC. This forms a computer network, however if both the system uses different operating systems, for example one system runs on windows and other one runs on MacOS then how can data be transferred between these two different systems, here comes the role of a OSI model which is a seven layered model that defines how a data can be transferred between different systems. 4.  OSI model  was introduced by International Organisation for standardisation (ISO) in 1984. 5. There are  seven layers  in a OSI model Application layer Presentation Layer Session layer Transport layer Network Layer DataLink layer Physical layer Physical Layer We now learned that a transport layer converts the data into segments, network layer converts the segments into packe
