Software is the program that enables a computer to perform a specific task: this includes the operating system, and application software such as graphic package and a web browser.
Hardware is any electronic or mechanical part. The basic structure of a computer system is made up of three main hardware sections; one the central processing unit – or CPU – two, the main memory, and three, the peripherals. The CPU is a processor chip which executes program instructions and coordinates the activities of all the other components. In order to improve the computer’s performance, the user can add expansion cards for video, sound and networking.

SUCCESS of the WWW Set off in 1989, the WWW quickly gained great popularity among Internet users. What is the reason for the immense success of the World-Wide Web? Perhaps, it can be explained by CERN's* attitude towards the development of the project. As soon as the basic outline of the WWW was complete, CERN made the source code for its software publicly available. CERN has been encouraging collaboration by academic and commercial parties since the onset of the project, and by doing so it got millions of people involved in the growth of the Web. The system requirements for running a WWW server are minimal, so even administrators with limited funds had a chance to become information providers. Because of the intuitive nature of hypertext, many inexperienced computer users were able to connect to the network. Furthermore, the simplicity of the Hyper Text Markup Language, used for creating interactive documents, allowed these users to contribute to the expanding database of documents on the Web. Also, the nature of the World-Wide Web provided a way to interconnect computers running different operating systems, and display information created in a variety of existing media formats. In short, the possibilities for hypertext in the world-wide environment are endless. With the computer industry growing at today's pace, no one knows what awaits us in the 21st century.. Note * CERN was originally named after its founding body the 'Conseil Europeen pour la Recherche Nucleaire,' and is now called 'European Laboratory for Particle Physics'.

This internal memory is made up of ROM and RAM chips. RAM, or random access memory, is volatile, so it loses the stored data when the electricity - or power – is turned off. ROM, or read only memory, is non volatile. The peripherals are the physical units attached to the computer. They include input, output abs storage devices, for example the keyboard and the mouse, enable us to present information to the computer. Output devices allow us to extract the results from the computer. For instance we can see the output on the monitor or in printed form. Storage devices are used to store information permanently. For example we use hard disks, DVDs or flash devices to store large amounts of information.
