A bytes. boolean operators are simple words

A bit isthe least amount of data in the computer.

Bits have a single binary value, 0 or1. Computers typically provide commands to control and manipulate bits, but aretypically designed to store data and to access bit numerous instructions calledbytes. Boolean operators are simple words (AND, OR, XOR & NOT) Join whichjoins or excludes search terms in belonging search Productive results. Avoidinappropriate strokes and save time and effort. It must be scanned before beingdestroyed. ANDrepresent that one statement is true and other is false. OR represent any onestatement is correct.

XOR represent only one statement is true. Not represent wewill give input then they give to contrast output. A Device which give us anoutput When we give input . it is called Gates. A group of a circuits is knownas Flip Flop. Forthe determination 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 hand of this row its known 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 direction, a computer’s main memory its knownrandom access 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 Revolving 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. Thecode which does is encoded to audios and videos.

This code is called MPEG. Images normally encode in GIF. how data can be encoded as bit patterns. Ourstudy focuses on popular methods for encoding Text, Numerical data, Images, andSound. Each of these systems has repercussions that are often visible to atypical computer user. Information in the form of text is normally representedby means of a code in which each of the different indication in the text (suchas the letters of the alphabet and punctuation marks) is assigned a uncommon bitpattern. The text is then represented as a long string of bits in which the succeedingdesigns represent the successive indication in the original text storinginformation in terms of encoded characters is inefficient when the informationbeing recorded is purely numeric. Suppose the problem of storing the amount 25.

If we insist on storing it as encoded symbols in ASCII using one byte persymbol, we need a total of 16 bits. Moreover, the largest number we could storeusing 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.
