Internet provides high visibility at very low cost, making it the most effective and fastest means of global communication. In the age of internet communication, a basic knowledge of the workings of the computer and internet is very necessary for all business environments.
The internet is a storehouse of information and a powerful medium of information distribution. In the present world of information technology knowledge of how the computer works is very important.
The computer is divided into three parts, the hardware, the operating system and software.
The hardware is the actual electronic part of the computer which includes memory, hard drive capacity, different drives or storage space (e.g. CD-ROM, DVD, etc.) and screen.
The powerful the hardware the higher level of work the computer can perform for e.g. for multimedia applications, one needs a computer with large hard drive and minimum megabytes (MB) of memory.
The operating system (OS), or platform, determines general functionality (how the computer works) and interface ( what the design of the screen looks like) It also determines the kind of software that can be installed and run in the computer.
To connect to the Internet, one needs a browser and an ISP (Internet Service Provider). The browser is the software that allows the computer to access data on the World Wide Web; for example, Internet Explorer, Firefox , Google chrome are very popular browsers. The Internet is actually a huge centreless network of computers connected through individual servers – the part of a company’s computer network that connects directly to the Internet. For an individual user, one needs a provider that has a server in order to connect (usually at a set fee). Companies and institutions have their own servers. The web address or URL, Uniform Resource Locator is actually a link to a server. If one wants to publish any material on the Internet, such as a website, one needs a server to host your site.
