Working Process of Computer

Computer is an electronic device its work with the help of

1. Data
2. Process
3. Information

1. Data :- Data is a fractional part of information some time data has meaning or meaningless if data has meaning then meaning couldn't affect to human beings.

2. Process:- A set of steps carried out the refined data is called process in processing in processing computer convert data into information.

3. Information:- collection of data is called information when its meaning effect to human beings.

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...
