Summary:

A bit is
the little amount of data in the computer. Bits have a single binary value, 0
or 1. Computers typically provide commands to control and manipulate bits, but
are typically designed to store data and to access bit numerous instructions
called bytes. Boolean operators are simple words (AND, OR, XOR & NOT) Join
which joins or excludes search terms in belonging search Productive results.
Avoid inappropriate strokes and save time and effort. It must be scanned before
being destroyed. AND
represent that one statement is true and other is false. OR represent any one
statement is correct. In XOR only one statement is true. Not represent we will
give input then they give to contrast output. 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 data, a computer covers a large group of circuits (such
as flip-flops), each skilled of storing a single bit. This bit reservoir is
called the machine’s main memory. A computer’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 computer there is no left & right. Bits place
in a row. The left side of this row is called high order end and the other end
is low order end.

To categorize
specific 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 show
the capability to access cells in any way, a computer’s main memory its known random
access memory (RAM).Due to the decreasing limitation of store data in computer
and volatility of data, Mostly in computers have additional memory device. This
is called mass storage. A turning disk is magnetic coated .It is used to read
and write data, is called magnetic disk. Another class of mass storage systems
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 detects
irregularities on the reflective surface of the CD as it spin.  A Flash drive is an ultra- portable device.
It is very small and unlike an optical or conventional hard drive .This device
is the combination of USB device and cable. Data store in the form of group as
large unit. it is called file. The
technique which is used to data transferring and storing .it is  reduce the size of data .It is called data
compression .This code not only detect the mistake but also correct the
mistake, its known as Error correcting code.

The code
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. Our study
focuses on popular methods for encoding Text, Numerical data, Images, and Sound.
Each of these systems has repercussions that are often visible to a typical
computer user. Information in the form of text is normally represented by means
of a code in which each of the different indication in the text (such as the
letters of the alphabet and punctuation marks) is assigned a uncommon bit
pattern. The text is then represented as a long string of bits in which the succeeding
designs represent the successive indication in the original text storing
information in terms of encoded characters is inefficient when the information
being 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 per
symbol, we need a total of 16 bits. Moreover, the largest number we could store
using 16 bits is 99. One means 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 is represented as a collection of these encoded pixels. Such a
collection is called a Bit Maps.
