Question

What is computer network and explain different types of network protocols?

Answer 1

Computer networks are any set of computers or devices connected together in order to share information or resources. A network can be very small (ex: a home network connecting 2 or more computers) or very large (ex: the internet). The actual physical medium of communication and the software controlling the communication are the two factors which limit the size and scalability of a network.

The set or rules which must be implemented in order to control communication is referred to as the protocols. The protocol defines the syntax, the semantics and the synchronization of communication. The protocols govern all aspects of the communication in such a way that two different computers can understand each other.

The protocols which enable communication between computers are human-made. There are several organizations responsible for creating standards such as:

ISO
ITU
ANSI
IEEE
IETF / IRTF
EIA
When creating protocols for network communication, there are many issues which must be considered.

Generic Protocol Issues [1]

Error control – making a channel more reliable and handling lost or out of sequence messages

Flow control – avoid flooding a slower peer entity

Resource allocation – mediating contention for physical (ex: buffers) or logical (ex: data structures) resources

Fragmentation – dividing chunks of data into smaller pieces and subsequent re-assembly

Multiplexing – combining several higher layer sessions

Connection setup – initiating logical communication with peer entity

Addressing / naming – managing identifiers

Compression – reducing data rate

Encryption – provide data security

Timer management – bookkeeping and error recovery

“Virtually all networks in use today are based in some fashion on the Open Systems Interconnection (OSI) standard. OSI was developed in 1984 by the International Organization for Standardization (ISO), a global federation of national standards organizations representing approximately 130 countries. The core of this standard is the OSI Reference Model, a set of seven layers that define the different stages that data must go through to travel from one device to another over a network.” [2]

computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server.

different types of network protocols are

1.TCP. Transmission control protocol is used for communication over a network

2.Internet Protocol (IP) IP is also working with TCP

3.FTP. File transfer protocol is basically used for transferring files to different network SMTP

4.HTTP

5.Ethernet

6.Telnet

7.Gopher

A computer network is a group of connected devices,such as computers,laptops,printers or mobile devices which can communicate with each other and share hardware and software resources.

NETWORK PROTOCOL

A network protocol helps to define the rules and convections for communication between network devices. The different network protocols are:-

HYPERTEXT TRANSFER PROTOCOL (HTTP)

This protocol is used to transfer files and data from one computer to another in World Wide Web(WWW).

HTTP SECURE (HTTPS)

This protocol is used to transfer files and data in a secure manner.

TRANSMISSION CONTROL PROTOCOL (TCP)

This protocol manages the delivery and verification of data packets.

FILE TRANSFER PROTOCOL (FTP)

This protocol is used to transfer files between computers and uses TCP to transfer files.
