A computer system consists of mainly four basic units; namely input unit‚ storage unit‚ central processing unit and output unit. Central Processing unit further includes Arithmetic logic unit and control unit‚ as shown in the figure:. A computer performs five major operations or functions irrespective of its size and make. These are • it accepts data or instructions as input‚ • it stores data and instruction • it processes data as per the instructions‚ • it controls all operations inside a computer

Computer Memory MEMORY IS THE INTERNAL STORAGE AREA OF THE COMPUTER. MEMORY IDENTIFIES THE DATA STORAGE.THE PHYSICAL MEMORY USUALLY REFERRED TO US MAIN MEMORY OR RAM. Different types of computer Memory Hard Disk Drive. The hard disk drives are among the most common types of computer memory. They can store the data and information long term as this is where you store your music‚ games‚ documents‚ and the like. Hard drives work much like records. They are spinning platters that have arms with head

Computer Animation Computer animators work to bring objects to life through the use of computer graphics. Like traditional animators‚ computer animators manipulate graphics and images to simulate movement. However‚ unlike traditional animators‚ computer animators use digital technology to create new visual effects and motions that help avoid the monotonous‚ frame-by-frame drawing required for each picture. Computer animation is a very lucrative business and shows no sign of slowing down in the future

Computer Networks NETWORKING CONCEPTS Network A network is basically an interconnection of various points to make a connected system e.g Road‚ Telephone‚ Social Data Network A computer network therefore refers to an interconnection of computers and other peripherals by use of a communication link Peer to Peer Networks In a peer-to-peer network‚ all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed

INTRODUCTION Computer is defined as an electronic computing device characterized by high speed and accuracy. It can handle data processing‚ storing‚ and retrieval following set of instruction and orders to get required results. Computer can process the operations according to the set of instruction and orders which are logically and algorithmically coordinated to solve a specific problem to get useful information and result. Computer is a programmable machine. This means it can execute a programmed

Imagine this‚ anyone‚ anywhere has the ability to connect to almost every computer in the whole world without even leaving this own home. Most of these computers are connected to the Internet which is‚ with the Internet’s growing popularity and widespread usage‚ one of the most susceptible targets to the continually growing hacking movement. The term hacker has caused much debate in regards to the actual meaning of it‚ but hacking by any definition is the art of thinking outside the box. In order to

The Computer Revolution If I were to make a history book of the years from 1981 to 1996‚ I would put computers on the cover. Computers‚ you may ask?‚ Yes computers‚ because if there were suddenly no computers on the world‚ there would be total chaos. People could not; communicate‚ commute‚ make business transactions‚ purchase things‚ or do most things in their daily routine‚ because power plants use computers to control the production of electricity. Computers have evolved extreme rapidly

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
