Web Application Basics and Definition

Updated on June 14, 2015

Web apps defined –

Simply put, a web application is a software or program that a user accesses through a web browser using the internet or a network. Most people who used a computer are already familiar with applications and programs as for sure, their computers have locally installed software.

A good example of locally installed software is Microsoft Office. A desktop program (other term for local program) is different from a web application as local programs only require to be installed on the computer and that the PC meets the minimum system requirement of the particular program. Once these two conditions are met, any user of the computer can launch and use the local application (of course this is assuming they have permissions to use the program).

Web apps on the other hand are applications that can run on any remote computer as long as that computer has a web browser and network connection. Some web applications require or can only be accessed on specific web browsers, while others require browser add ins or browser languages (e.g Java). Needless to say, web apps are dependent on the network connection speed on which the remote computer is using.

Web apps can be simple or complex. Simple web apps have been around even before the popularity boom of the internet. Examples of simple web apps are message boards and the PERL scripting language. However, as networking technology evolve, more complex web apps are developed as many businesses and organizations saw that they can maximize this technology potential. Nowadays, complex web apps not only involve file sharing but sharing of whole database, spread sheets, etc…
