Basics of Computer :: 1 1 Basics of Computer 1.1 INTRODUCTION In this lesson we present an overview of the basic design of a computer system: how the different parts of a computer system are organized and various operations performed to perform a specific task. You would have observed that instructions have to be fed into the computer in a systematic order to perform a specific task. Computer components are divided into two major categories‚ namely‚ hardware and software. In this lesson we

Are computers necessary? Computers have been around for many years and it has become difficult to imagine life without them. They are present almost everywhere we go - at the supermarket‚ at the bank‚ at home‚ in the car. Computers are more efficient than we humans are‚ at least when it comes to calculations and related topics - as the name computer implies (to compute - to calculate). The question is‚ however - could we do without computers? Are computers really necessary‚ or do we just use them

to perform operations on data.[1] Quantum computers are different from digital computers based on transistors. Whereas digital computers require data to be encoded into binary digits (bits)‚ each of which is always in one of two definite states (0 or 1)‚ quantum computation uses qubits (quantum bits)‚ which can be in superpositionsof states. A theoretical model is the quantum Turing machine‚ also known as the universal quantum computer. Quantum computers share theoretical similarities with non-deterministic

Computer technology permeates most aspects of our lives. The ability to use computer technology and to evaluate electronic information has become a basic skill for most of people. In most places of business‚ a computer is standard. In the bank they use computers to look up for account information. They use computers in the auto repair shop to assess the cars. We can’t find books in the library by looking in a card catalog — we must use a computerized database. Doctors’ offices utilize computers
