A bit is
the least 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
represent that one statement is true and other is false. OR represent any one
statement is correct. XOR represent 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 a 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 consist 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 hand of this row its known high order end and the other end
is low order end.
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 direction, 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 Revolving disk is magnetic coated it is used to read
and write data, is known as 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. Data store in
the form of group as large unit. it is called file 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.
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 Map.
