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...

Types Of Computer Network

There are so many different types of computer networks in existence; it can be hard to understand the differences between them, particularly the ones with very similar-sounding names. This lesson explains the structures and functions of some of the most popular computer networks. Types of Networks There are several different types of computer networks. Computer networks can be characterized by their size as well as their purpose. The size of a network can be expressed by the geographic area they occupy and the number of computers that are part of the network. Networks can cover anything from a handful of devices within a single room to millions of devices spread across the entire globe. Some of the different networks based on size are: Personal area network, or PAN Local area network, or LAN Metropolitan area network, or MAN Wide area network, or WAN In terms of purpose, many networks can be considered general purpose, which means they are used f...
