What is Computer Network: It means to connect multiple computer system with each other through physical medium (Cable or Wire) or wireless medium and this architecture is known as “Computer Network“.
In traditional computer networks, single computer machine, workstation, and servers are linked one by one through Ethernet and other cables. But now, advance technologies are released in market in which to make connection between multiple points through wireless technology.
Applications of Computer Network
There are different types of Computer network applications that are used in internet, and they are divided into in to two segments such as –
Pure Network
Standalone Network
Goals and Applications of Computer Network are
1. Pure Network Application
Pure network applications do not depend on the single computer machine because those applications help to make connection over network and to transfer data from one point to other points.
Some examples are –
Email Software
These types of programs help to users for writing messages at their local computer system, and forward it to other users over the network. This is very simple and easy way of moving mail (message) from one computer system to other computer machine.
Some mail programs are
Pegasus Mail
Outlook express
Eudora Windows mail
Fox mail
Opera
Poco mail
Mozilla Thunderbird
Windows mail
FTP
FTP stands for “File Transfer Protocol”, and it allows transferring all files from one computer machine to other computer machines like as client to server process.
File Transfer Protocol performs two tasks are
Upload file – In this process, users access all data from workstation to server machine. For example – upload images to Google drive.
Download file – In this process, users access all data from server to workstation machine (client). For example – download software from server.
Some File Transfer Protocol programs are
FTP in Unix
FTP in Linux
FTP in Windows
TELNET
TELNET stands for “Telecommunication Network”, and it is text based network protocol that is implemented on the LAN connections otherwise internet system. TELNET allows to users for getting access remote computer machine over TCP/IP networks (internet), and to make communication in between both terminals.
Groupware
Groupware applications are implemented in the advance offices, where is needed to automate and administrative functionalities for examples are chatting (text/video) and video conferencing. These applications help to increase productivity and solve problems. Groupware is an internal part of education known as (CSCW) Computer-Supported Cooperative Work.
Video Conferencing
Video Conference means to make conference between two parties on the different zone (remotely) with helping computer network to transmit voice and video data.
For making video conference, both participants must be video camera, microphone, and speakers connected on their computer machine.
There are some types of video conference such as –

Integrated Video Conferencing System
Desktop Video Conferencing System
Service-based Video Conferencing System
Codec

ICQ (I seek you)
IRC (Internet Relay Chat)
Some Best Chat Apps
WhatsApp
Telegram
GroupMe
Line
WeChat
Kakao Talk (KaTalk)
Kik Messenge
2. Stand Alone Applications
Stand Alone Applications are used in some years ago, which are installed on every client machines, and these are independent platform, as well as they can operate offline. These applications can be operated on any your favorite operating system, and all data of applications are saved on Central server to make synchronization between server and applications.
