A bit is the little amount of T in thecomputer. Bits have a single binary value, 0 or 1. Computers typically providecommands to control and manipulate bits, but are typically designed to store Tand to access bit numerous instructions called bytes. Boolean operators aresimple words (AND, OR, XOR & NOT) Join which joins or excludes search termsin belonging search Productive results.
Avoid inappropriate strokes and savetime and effort. It must be scanned before being destroyed. AND represent that one statement is true andother is false. OR represent any one statement is correct.
In XOR only onestatement is true. Not represent we will give input then they give to contrastoutput. A Device which give us an output when we give input .It is called Gates.A group of circuits is known as Flip Flop. For the determination of storing T, acomputer covers a large group of circuits (such as flip-flops), each skilled ofstoring a single bit. This bit reservoir is called the machine’s main memory. Acomputer’s Main memory organize in controllable units this unit is called cell.
Every cell consists of 8 bits and 8 bits is equal to one byte. In a computerthere is no left & right. Bits place in a row. The left side of this row iscalled high order end and the other end is low order end.To categorize specific cells in a computer’smain memory, each cell is allocated a unique “name” is called address. Incomputer’s main memory is organized as specific, addressable cells, the cells canbe recover independently as needed.
To show the capability to access cells inany way, a computer’s main memory its known random access memory (RAM).Due tothe decreasing limitation of store T in computer and volatility of T, Mostly incomputers have additional memory device. This is called mass storage. A turningdisk is magnetic coated .It is used to read and write T, is called magneticdisk. Another class of mass storage systems applies visual technology.
Anexample is the compact disk (CD). Information is recorded on them by creatingvariations in their reflective surfaces. This information can then be retrievedby means of a laser beam that detects irregularities on the reflective surfaceof the CD as it spin. A Flash drive isan ultra- portable device. It is very small and unlike an optical orconventional hard drive .
This device is the combination of USB device andcable. T store in the form of group as large unit. it is called file. The technique which is used to T transferringand storing .it is reduce the size of T.It is called T compression .This code not only detect the mistake but alsocorrect the mistake, its known as Error correcting code.
The code which does is encoded to audios andvideos. This code is called MPEG. Images normally encode in GIF. how T can beencoded as bit patterns. Our study focuses on popular methods for encoding Text,Numerical T, Images, and Sound. Each of these systems has repercussions thatare often visible to a typical computer user. Information in the form of textis normally represented by means of a code in which each of the different indicationin the text (such as the letters of the alphabet and punctuation marks) isassigned a uncommon bit pattern. The text is then represented as a long stringof bits in which the succeeding designs represent the successive indication inthe original text storing information in terms of encoded characters isinefficient when the information being recorded is purely numeric.
Suppose theproblem of storing the amount 25. If we insist on storing it as encoded symbolsin ASCII using one byte per symbol, we need a total of 16 bits. Moreover, thelargest number we could store using 16 bits is 99. One means of representing animage is to interpret the image as a collection of dot. The appearance of eachpixel is then encoded and the entire image is represented as a collection ofthese encoded pixels.
Such a collection is called a Bit Maps.
