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

BASIC STRUCTURE OF A COMPUTER SYSTEM

Computer Function A computer performs action and accomplishes its task in three basic stages namely:- INPUT – Input is the data that is fed into the computer by the user. PROCESS – Processing refers to the series of action by which the computer converts raw data into information. OUTPUT – Output is the result which is termed as information. Input Unit Data and instructions enter a computer through an input unit in a form that depends upon the input device used. Ex- Keyboard, Mouse, Joystick, Scanner etc. CENTRAL PROCESSING UNIT (C.P.U) CPU is also known as the brain of the “Brain of Computer”. As it appears as a hardware component, but it is also a functional component of a computer system. Functional Elements of a CPU        1.        Arithmetic Logic Unit(ALU)        2.        Control Unit(C.U)        3.    ...

DEVICES USED IN NETWORK

  1. MODEM: It stands for Modulator- Demodulator. A   modem is a peripheral device which modulates ( convert   digital signals to analog signals) and demodulates( convert   analog signals into digital signals) at the local workstation.   The sending and receiving ends of the communication must   have a modem. Now a days mobile phones have inbuilt   modem devices that help to browse internet.      2. Switch: A network switch is a small hardware device that is used to amplify data signals & create smaller network segment or several subnets of bigger network. It is used to prevent overloading of data in the traffic of a network. It is also responsible for forwarding and transforming data packets between the sub networks.    3. HUB:   A hub is a hardware device which provides common connection point to connect several devices together in a network. It contains multiple ports on which wo...

Media Of Communication Part 2

Unguided Media Unguided media transport electromagnetic wave without using a physical connection. This type of communication referred as wireless communication. We can divided wireless transmission in :-   1. Radio Wave:- Electromagnetic   waves ranging in frequencies between 3KHz and 1GHz are normally called radio wave.   On radio wave connectivity used communication used Bluetooth, Wi-Fi, etc.     Bluetooth :- It is a wireless network connectivity that enables to connect or transfer data between devices over a short range the physical range of connection up to 100 meter. Ex- Mobile phone, barcode scanning, portable speaker, wireless keyboard, mouse etc.      Wi-Fi (Wireless Fidelity):- Wi-Fi is a network of wireless connection. Wi-Fi network establish by radio frequency like Bluetooth, but has more power, resulting a strong connection.    ·   Wi-Fi is also called wireless Ethernet. It has connectivity range up...
