Functions Of Computer

Any digital computer carried out difference function :-

    1. Takes data from user through input device.(Input unit)
    
    2. Process the data through processing unit (Processing unit)

     3. Store the data through storing device (memory unit) 

     4. Get desired output through (Output unit)
   
    5.  Control all over four operation (Control unit)
So we can say that computer functioned depend on their essential devices, these device are
   
                    1. Input unit 
            
                     2. Processing unit + Control unit ( CPU) 

                      3. Memory unit
                   
                     4. Output unit

Introduction to Computer

COMPUTER- Basically the term COMPUTER is derived from "GREEK" word which means to calculate. Hence we can say that computer is a calculating device. In other word we can say that Computer is an electronic device which store data processing and give out the result. A computer is an electronic device which performs "Arithmetical and logical operation. A computer understood binary digit that is 0 and 1. Computer is an electronic device which accepts  data form user through input device and process the data with the help of processor after processing we desired output form. A computer also refereed as data processor because It can store the data, Process the data, and Retrieve data whenever desired. FULL FORM OF "COMPUTER" C-  Calculate O- Operate M- Machine P- Process U- User T- Trade E- Education R- Research

Network Topology

Types of Network Connections Computer networks can be broken down historically into topology , which is a technique of connecting computers. The most common topology today is a collapsed ring. This is due to the success of a network protocol called the Ethernet. This protocol, or network language, supports the Internet, Local Area Networks, and Wide Area Networks. Star Topology A star topology is a design of a network where a central node extends a cable to each computer on the network. On a star network, computers are connected independently to the center of the network. If a cable is broken, the other computers can operate without problems. A star topology requires a lot of cabling. Bus Topology A bus topology is another type of design where a single cable connects all computers and the information intended for the last node on the network must run through each connected computer. If a cable is broken, all computers connected down the line cannot r...

Number system and its types:-

Number system :- This is the medium by which we can represent the number into equivalent of different format when we type some letter or word the computer translate them a number because computer can understood only number. Types of number system      Positional number system      Non positional number system   Positional Number System: In positional number system, there are only a few symbols called digits, and these symbols represent different values depending on the position they occupy in the number. The value of each digit in such a number is determined by three considerations__ 1.        The digit. 2.        The position of the digit in the number. 3.        The base of the number system. Non-Positional Number System:  In the non-positional number systems, the characters used are I for 1, II for 2, etc, and are of...
