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 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 side of this row is called 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 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 spinning 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.
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.
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 Maps.
