NUMBER SYSTEM

NUMBER SYSTEM
Number system is a way to represent a no in very systematic order and we also know that a number represent quantity (some time quality) of the product.
        In Computer Science number system has significance value there are four different types of number system.
The four different types of number system is as follows:
i)                Binary Number System
ii)             Octal Number System
iii)         Decimal Number System
iv)          Hexa- Decimal Number System
Each Number System has two different attribute first is known as ‘radix’ or ‘base’ and another is ‘range’.
Radix defined worth are repeatable properties of particular number and Range specifies a number of digits.

Number System
Radix
Range
Example
Binary
2
0,1
(110)2
Octal
8
0,1,2,3,4,5,6,7
(5746)8
Decimal
10
0,1,2,3,4,5,6,7,8,9
56789
Hexa-Decimal
16
0,1,2,3,4,5,6,7,8,9,
A,B,C,D,E,F
(3AF)16

Decimal Number System
This is the natural number system as a human being, we are working on decimal number system and we are very comfortable   in performing different operation in this number system. The base of this number system is 10.
Ex- 780,1058,589658 etc.
Binary Number System
It is also known as machine number system.It has only two digits '0' and '1' and its base is 2. In Computer science every data is represented in binary format.
Ex- (11110011)2
Octal Number System
It is also machine number sustem, generally used by  computer system for memory refrence or some specific data values. It has base 8 and digits are 0,1,2,3,4,5,6,7.
Ex- (176)8
Hexa-Decimal Number System
It has base 16 and digits are 0,1,2,3,4,5,6,7,8,9 and A,B,C,D,E,F . Here A =10, B=11, C=12, D=13, E=14 and F=15.
It is used in network adressess.
Ex- (98EF)16

Computer Generations

 Computer Generations   Computers have evolved over time through different generations, each marked by significant technological advancements and changes in design and architecture. These generations are often categorized based on the underlying hardware and the key developments that distinguish one Generation from another. Let's explore the main computer generations: First Generation Computers    The First Generation of computers refers to the initial period of electronic computing, characterized by the use of vacuum tubes as the primary electronic component. This Generation spans the 1940s and 1950s and is marked by groundbreaking developments in computer technology.  Examples of First-Generation Computers:  o ENIAC (Electronic Numerical Integrator and Computer): Completed in 1945, ENIAC was one of the first electronic general-purpose computers. It was designed to calculate artillery firing tables for the United States Army during World War ...

Computer Basic

  The word “computer” comes from the word “compute”, which means to calculate”. Charles Babbage is known as the ' Father of computer' .  A computer often referred to as a “data processor” because it can store, process, and retrieve data whenever desired.  The activity of processing data using a computer is called data processing.    Data processing consists of three sub activities:- (1)          Capturing input data (2)          Manipulating the data and (3)          Managing output results. Data : - Data is raw material used as input to data processing. Data can be anything like numerical, non-numerical or a mixture of both. Information : - Information is processed data obtained as output of data processing. Computer: - A computer is an electronic device which performs numerical calculation and logical calculation at hig...

Office Package and Features of Office Package

Most of the official jobs today are dependent on computers. Computer helps in accomplishing different types of official tasks with the help of 'Office Package'. With the help of 'Office Package ' to accomplish basic tasks like typing and composing letters, doing calculations and comparisons, manipulation data and generating multiple types of reports, making presentation for demonstration, seminars etc.   For example: MS Office, OpenOffice, etc. Office package includes the following applications: 1. Word Processor:  A word processor is a type of application software that enables to create a documents by enabling to type text, insert page number, header, footer, edit, modify , and to take print or save documents in soft copy for future use.   2. Spreadsheet:   A spreadsheet package is an application software that stores data in an organized way and help to  analyse, calculate, compare the data or values. It also enables to present information in graphs, pie c...
