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

Computers and culture | Computers and their role in human life have changed drastically since the 1950s. If 60 years ago computers did not play an important role in society‚ these day computers play a significant role in our lives. Initially‚ computers were big and awkward machines that were used just for keeping information and calculations. Throughout the last 50 years computers have become much smaller and much more sophisticated. If first computers were so large that they

computer ------------------------------------------------- Computational chemistry From Wikipedia‚ the free encyclopedia Computational chemistry is a branch of chemistry that uses principles of computer science to assist in solving chemical problems. It uses the results of theoretical chemistry‚ incorporated into efficient computer programs‚ to calculate the structures and properties of molecules and solids. Its necessity arises from the well-known fact that apart from relatively recent results

Section 1 Introduction 1.1 COMMUNICATIONS Computer communications is the process of sharing data‚ programs‚ and information between two or more computers. We have discussed numerous applications that depend on communication systems‚ including: • E-mail – Provides a fast‚ efficient alternative to traditional mail by sending and receiving electronic documents. • Instant messaging – Supports direct‚ “live” electronic communication between two or more friends or buddies. • Internet

This decision had far reaching effects on Bill Gate’s life. For at Lakeside‚ Bill Gates was first introduced to computers. BILL GATES: CHAIRMAN William (Bill) H. Gates is chairman of Microsoft Corporation‚ the worldwide leader in software‚ services and solutions that help people and businesses realize their full potential. On June 27‚ 2008‚ Gates transitioned out of a day-to-day role in the company to spend more time on his global health and education work at the Bill & Melinda Gates Foundation

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
