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 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 consists of 8 bits and8 bits 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 called magnetic disk. Another class of mass storage systemsapplies visual technology. An example is the compact disk (CD). Information isrecorded on them by creating variations in their reflective surfaces.
Thisinformation 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 of USB 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 encoding Text,Numerical data, 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. the techniquewhich is used to data transferring and storing .it is reduce the size of data .It is called datacompression
