Some common computer icons are taken from the broader field of standardized icons used across a wide range of electrical equipment. Examples of these are the power symbol and the USB icon‚ which are found on a wide variety of electronic devices. The standardization of electronic icons is an important safety-feature on all types of electronics‚ enabling a user to more easily navigate an unfamiliar system. As a subset of electronic devices‚ computer systems and mobile devices use many of the same icons;

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

INPUT DEVICES Barcode reader A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes. Like a flatbed scanner‚ it consists of a light source‚ a lens and a light sensor translating optical impulses into electrical ones. Additionally‚ nearly all barcode readers contain decoder circuitry analyzing the barcode’s image data provided by the sensor and sending the barcode’s content to the scanner’s output port.

A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed‚ the computer can solve more than one kind of problem. Ads by Plus-HD-V1.5c×Conventionally‚ a computer consists of at least one processing element‚ typically a central processing unit (CPU)‚ and some form of memory. The processing element carries out arithmetic and logic operations‚ and a sequencing and control
