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.

User dependency on the Internet increases every day; nowadays, everyday tasks like paying bills, communicating with others, and applying for jobs are all routinely carried out via the Internet. While the Internet represents a huge network, it is meaningless without the applications that it supports. These applications enable user interaction and facilitate everyday activities.

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.
