Computer system A computer system consists of a computer and supporting devices for input/ output of data. The basic organization of any computer system shown in the following diagram Input device --- computer --- out put device  The input device supplies the data, as obtained from us, to the computer. Most commonly used input devices are – teletypewriter, video display unit ( VDU ). We specify the data in a form which we use in our everyday life, that is, in the numeric and alphabetic form. These are converted into the forms which the computer can understand. Data are stored in the computer in the binary form. After the computer has processed the data results are obtained on the output devices. Commonly used devices are printer, VCD and teleprinter. The results obtained are in the human readable form. Computer data is changed into this form by electronic circuits called decoders. The computer does all the computing data processing work. Its component are : Arithmetica...

Introduction A computer is simply a tool for people to use ; it is a machine that can solve any problem by accepting data , performing certain operations on that data , and presenting results of those operations. A computer is an information processing machine. It can perform arithmetic operations and the logical decisions . it has a memory and can store lots of information. The stored information may be retrieved , moved and operated upon as desired. Computation are done at an extremely fast speed with complete reliability and accuracy. The speed of execution of operation by modern computer is several million operations per second in comparison to slow computers. These are basically three types of computers - Analog , digitaldigital and hybrid. Analog computer An analog computer accepts , processes and generates continuous data. Computation are carried out with physical quantities , such as length, voltage, current, etc. Digital computer A digital computer accepts , p...

Introduction  Information and communication technology usually called ICT, is often used as an extended synonym for information technology ( IT), but is usually a more general term that stresses the role of unified communication and the integration of telecommunications ( telephone lines and wireless signals ) , intelligent building management systems and audio visual systems in modern information technology.  ICT consists of all technical means used to handle information and aid communication, including computer and network hardware, communications middleware as well as necessary software. In other words, ICT consists of IT as well as telephony, broadcast media, all types of audio and video processing and transmission and network based control and monitoring functions. ICT is often used in the context of ICT roadmap to indicate the path that an organization will take with their ICT needs. The term ICT is now also used to refer to the merging of audio visual and te...
