A bit is the little amount of T 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 T
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 T, 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 T in computer and volatility of T, 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 T, 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. T store in the form of group as large unit. it is called file. The technique which is used to T transferring
and storing .it is  reduce the size of T
.It is called T 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 T can be
encoded as bit patterns. Our study focuses on popular methods for encoding Text,
Numerical T, 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.
