A specific, addressable cells, the cells can

A bit isthe little amount of data in the computer. Bits have a single binary value, 0or 1. Computers typically provide commands to control and manipulate bits, butare typically designed to store data and to access bit numerous instructionscalled bytes. Boolean operators are simple words (AND, OR, XOR & NOT) Joinwhich joins or excludes search terms in belonging search Productive results.

Avoid inappropriate strokes and save time and effort. It must be scanned beforebeing destroyed. ANDrepresent that one statement is true and other is false. OR represent any onestatement is correct. In XOR only one statement is true. Not represent we willgive input then they give to contrast output.

A Device which give us an outputwhen we give input .It is called Gates. A group of a circuits is known as FlipFlop. For thedetermination of storing data, a computer covers a large group of circuits (suchas flip-flops), each skilled of storing a single bit.

This bit reservoir iscalled the machine’s main memory. A computer’s Main memory organize incontrollable units this unit is called cell. Every cell consist of 8 bits and 8bits is equal to one byte. In a computer there is no left & right. Bits placein a row. The left side of this row is called high order end and the other endis low order end.

To categorizespecific cells in a computer’s main memory, each cell is allocated a unique”name” is called address. In computer’s main memory is organized as specific,addressable cells, the cells can be recover independently as needed. To showthe capability to access cells in any way, a computer’s main memory its known randomaccess memory (RAM).

Due to the decreasing limitation of store data in computerand volatility of data, Mostly in computers have additional memory device. Thisis called mass storage. A turning disk is magnetic coated .It is used to readand write data, is known as magnetic disk. Another class of mass storagesystems applies visual technology. An example is the compact disk (CD).

Information is recorded on them by creating variations in their reflective surfaces.This information can then be retrieved by means of a laser beam that detectsirregularities on the reflective surface of the CD as it spin. Data store inthe form of group as large unit. it is called file this code not only detectthe mistake but also correct the mistake, its known as Error correcting code.A Flash drive is an ultra-portable device.

It is very small and unlike an optical or conventional harddrive .This device is the  combination ofUSB device and cable. The code which does is encoded to audios andvideos. This code is called MPEG. Images normally encode in GIF. how data canbe encoded as bit patterns. Our study focuses on popular methods for encodingText, Numerical data, Images, and Sound. Each of these systems hasrepercussions that are often visible to a typical computer user.

Information inthe form of text is normally represented by means of a code in which each ofthe different indication in the text (such as the letters of the alphabet andpunctuation marks) is assigned a uncommon bit pattern. The text is thenrepresented as a long string of bits in which the succeeding designs representthe successive indication in the original text storing information in terms ofencoded characters is inefficient when the information being recorded is purelynumeric. Suppose the problem of storing the amount 25. If we insist on storingit as encoded symbols in ASCII using one byte per symbol, we need a total of 16bits.

Moreover, the largest number we could store using 16 bits is 99. Onemeans of representing an image is to interpret the image as a collection of dot.The appearance of each pixel is then encoded and the entire image isrepresented as a collection of these encoded pixels. Such a collection iscalled a Bit Maps.
