BASIC CONCEPTS IN COMPUTING WHAT IS A COMPUTER A computer may be defined as an electronic device that has the capability of accepting and processing data under the control of a stored program and producing output in the form of information. This information may be in the form of sound‚ images‚ electronic signals‚ etc. and may be stored within the computer or on an external storage device. Computers are not very intelligent but they handle instructions flawlessly and fast. They must follow explicit

Computer keyboard In computing‚ a keyboard is a typewriter-style device‚ which uses an arrangement of buttons or keys‚ to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape‚ interaction via teleprinter-style keyboards became the main input device for computers. A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However‚ to produce some symbols requires pressing

UNIT-I INTRODUCTION INTRODUCTION TO COMPUTER The term “Computer” is derived from the Latin word “Computare” which means “to compute” or “to calculate”‚ so it is considered to be calculating device. In fact‚ the main objective of inventing the computer was to create a fast calculating machine. But now-a-days more than 75% of non-mathematical or non-numerical work is carried out by the computers. Today‚ computer technology has spread to every sphere of existence of modern man‚ from railway

Biometrics Biometrics[1] (or biometric authentication)[note 1] refers to the identification of humans by their characteristics or traits. Biometrics is used in computer science as a form of identification and access control.[2] It is also used to identify individuals in groups that are undersurveillance.[citation needed] Biometric identifiers are the distinctive‚ measurable characteristics used to label and describe

Tomorrow’s Technology and You textbook. Chapter 1 1. What is the most important difference between a computer and a calculator? [RQ‚ no. 2] Calculators perform operations one at a time‚ while computers can process a sequence of operations using provided instructions. A typical calculator requires many interactions to perform a computation‚ while a computer takes a set of instructions. 2. How are computers today similar to those from World War II? How are they different? [RQ‚ no. 3] 3. The way people

the modern electronic computer was developed at U.S. universities; however‚ in the year‚ there was no computer education yet. It needed more 10 years to have computer education. The period of the computer revolution was 1950 in the U.S.. Computer education began in the middle of the 1950s with an organized body of knowledge. Also Japanese the teaching of computer science has been developed in the same period. During 1955 to 1959‚ some universities developed their own computers. They organized short

Computer Engineer is involved in various tasks of computing like designing‚ programming related to software and also tasks with respect to hardware. So it is vital that they have proper blend of sound knowledge on both areas. Computer engineers take part in challenging and critical projects and must have the ability to work on a broad range of technologies in diversified critical project areas. For achieving a sound result on the above it is vital that the computer engineers must possess an in-depth

of the military and industry in the development of electronics‚ computers‚ and information theory. After the 1940s‚ the military remained the major source of research and development funding for the expansion of automation to replace manpower with machine power. Since the 1950s‚ four generations of computers have evolved. Each generation reflected a change to hardware of decreased size but increased capabilities to control computer operations. The first generation used vacuum tubes‚ the second used
