-Analog computer system is the very old computer system which operates on the mathematical variables in the form of continuously changeable physical quantities/entities like mechanical, electrical, hydraulic, etc. They use continuous values rather than discrete values so they work on analog signal. At the time of at the time of the 1950s–1960s these analog computers were first used. Analog computers are limited in accepting the problems and also they can never be extremely accurate.

-Digital computers are the computer systems/machines which uses the binary number system, which has two digits: 0 and 1 and performs many computational tasks. It processes the data represented in discrete and the main three components of digital computers are input, processing and output. The first digital computer was designed for numerical computations in the late 1940s. Digital computers give results with more accuracy as it is not dependent upon physical quantities for processing a task.

– Access to information: Increase in access to information and services that has accompanied the growth of the Internet. Some of the positive aspects of this increased access are better, and often cheaper, communications, such as VoIP phone and Instant Messaging.

– New tools, new opportunities: ICT gives access to new tools that did not previously exist: digital cameras, photo-editing software and high quality printers, screen magnification or screen reading software enables partially sighted or blind people to work with ordinary text rather than Braille.

– Communication: Cost savings by using e.g. VoIP instead of normal telephone, email / messaging instead of post, video conferencing instead of traveling to meetings, e-commerce web sites instead of sales catalogues. Access to larger, even worldwide, markets.
