Applications of Computer Networks

Patrick, a computer technician, is a dedicated writer who wishes to make the world better by informing individuals who seek more knowledge.

Applications of Computer Networks

A network is a collection or set of computing devices connected to one another to establish communication and also share available resources. A network will comprise software and hardware devices. You can have a network even if you are not connected to the internet. Computer networks make it possible for people to transfer files from one place to another and to communicate taking the shortest time possible.

Computer network applications are network software applications that utilize the Internet or other network hardware infrastructure to perform useful functions for example file transfers within a network. They help us to transfer data from one point to another within the network.

There are 2 types of network applications:-

  1. Pure network applications
  2. Standalone network application

(A) Pure Network Applications

These are applications created to be used in networks; using pure network applications on a single computer doesn't make sense. They help us to transfer data and communicate within a network. Such applications have a separate and distinct user interface that users must learn for instance:-

Outlook Express

Outlook Express, an email program

1. Email Programs

They allow users to type messages at their local nodes and then send to someone on the network. It is a fast and easy way of transferring mail from one computer to another. Examples of electronic mail programs (Clients) are:-

  • Pegasus Mail
  • Outlook express
  • Eudora Windows mail
  • Fox mail
  • Opera
  • Poco mail
  • Mozilla Thunderbird
  • Windows mail

2. File Transfer Protocol (FTP)

This application facilities transfer of files from one computer to another e.g. from a client to a server. There are 2 common processes involved in FTP

Downloading: - This is the process of obtaining files from a server to a workstation or a client (for example when you download programs and music from a server).

Uploading:- This is obtaining of files from a workstation to a server (for instance when you attach documents and upload them to a server, a good example being when you upload photos to Facebook).

Examples of FTP programs are:-

  • FTP in Unix
  • FTP in Linux or
  • FTP in Windows

3. Terminal Emulation (TELNET)

It allows a workstation to access the server for an application program. This enables you to control the server and communicate with other servers on the network. The workstation appears as a down terminal that is directly attached to the server. The user feels like he/she is using the server directly. TELNET enables PCs and workstations to function as dumb terminals in sessions with hosts on inter-networks.

4. Groupware

These applications are used to automate the administrative functions of a modern office for instance video conferencing and chatting. They facilitate the work of groups and improve on their productivity; they can be used to communicate, co-operate, coordinate, solve problems, compete, negotiate among others.

(i) Video Conferencing

This is the process of conducting a conference between two or more participants at different sites by using computer networks to transmit audio and video data. For example, a point-to-point (two-person) video conferencing system works much like a video telephone.

Each participant has a video camera, microphone, and speakers mounted on his or her computer. As the two participants speak to one another, their voices are carried over the network and delivered to the others speakers, and whatever images appear in front of the video camera appear in a window on the other participant’s monitor.

(ii) Chatting

It is real-time communication between two users via computer. Once a chat has been initiated, either user can enter text by typing on the keyboard and the entered text will appear on the other user’s monitor. The two must be online for a chat to be initiated. Most networks, cybers and online services offer a chat feature which enables computer users to chat as they go on with their work.

(B) Stand Alone Applications

These are applications that run on stand-alone computers (computers not connected to any other). In order to extend their activity, they are rebuilt to run on network environments e.g. word processors, spreadsheets, database management systems, presentations graphics, project management etc. They function even when the computer is offline.

Questions & Answers

Question: What is a standalone application?

Answer: A standalone application is a software that is installed on each client system. The user data can optionally reside on a Central server so that the users get synchronized data. Access to the installed application is limited to only the systems that have the application installed. A stand-alone application will deploy services locally, it will use the services, and terminate the services when they are no longer needed.

Question: What is a Network Protocol?

Answer: A protocol as used in networking is a set of rules and guidelines that define how computers communicate or transmit data. Rules are defined for each step and process during communication between two or more computers. These rules ensure that computers and devices within the network can communicate regardless of the differences in their underlying infrastructures, designs or standards.

Question: What is the role of network applications?

Answer: Network Applications enable people or even computers to communicate within a network. These applications use a client-server architecture, where the client and server are two computers connected to the network. The server is programmed to provide some service to the client.

The client is just a desktop, laptop or portable device like a smartphone. The server can be any of these, but in most cases, it is a computer in a data center running some specialized software.

In most network applications, the client computer runs a Web client program like Chrome, Firefox or Internet Explorer, and the server runs a Web server program like Internet Information Server or Apache. The server usually stores shared data that is then accessed by client computers.
