| Computer Introduction |
The Nature have gifted human beings a powerful communication resource in the form of language to interchange ideas and communicate. Human being, using his excellent intelligence, developed computer, to manage and generate information, as per our requirements, in a systematic manner. Computer helps business organisation manage and allocate resources properly by aiding managers in decision-making process. managing an industry is almost as good as managing the information for control and decision making. Airlines and \Railway reservation system with database client-server architecture and real-time on -lie translation processing system has given us feel of betterment. In these days, our scientists is working on super quantum theory or method to developing a quantum computer also. The Quantum computing is the area of study focused on developing computer technology on the principles of quantum theory, which explains the nature and behavior of energy and matter on the quantum( atomic and subatomic ) level.
Internet are the network of networks that provides access to people and information. These are a world-wide network of computers holding vast quantity of data that can be accessed directly from a personal PC. The internet is the biggest ever advantage of computer era. Electronic clearance system, personal banking, cash drawl through ATM, payment through debit or credit card, mobile phone, home PC- all these are growing and influencing our personal life and social culture. All our space research programs are supported by heavy super computer systems for example, exchange of information from earth-bases to sky- labs and vice-versa. In our social life, internet and e-mailing are fast spreading.
The computer Industry includes business that creates and supplies technology as well as enterprises educate and provide proper training in its use. The scenario, on the education-front has also got impacted to such an extent that a new branch or faculty in education called, Information Technology has evolved. Computer have influenced business so much, that many business transactions are now-a-days made through computer electronically. The bilateral business transactions when processed electronically through computers are termed as |E-business. All e-business activities in aggregate constitute "e-commerce".
Today, defense of any nation relies majorly on the advancement of its computer systems. computers guide missiles to their destinations accurately, and navigate fighter planes to attack on the weakest parts of enemy-bases. Any defense activity without computers are almost impossible today. Computers and telecommunication have overcome all geographical constraints to such an extent that the whole would have changed to a global village. The biggest economic revolution 'globalization' is the result of the same computers.Therefore, full credit to make this revolution, an existing truth, must be given to computers and computer-related technologies.
Meaning of computer-- The word computer comes from word compute which means "To calculate" has something to do with calculation in other words, A computer is a high speed electronic device capable of performing arithmetic and logical operations and of sorting and executing a set of instruction.
The Computer-- Computer is a high speed electronic Device.Which is capable to perform Arithmetic or mathematical and logical operation by using set of instruction. set of instruction mean a program. and give a perfect result to user. There are many type of computer available in the market some are cheapest and some are expensive but the aim of every computer are different.computer is capable of doing complex calculations in fraction of a second with accuracy.Of late, banks, military, space prediction, Home ministry are totally dependent on computers to accomplish their work in the minimum time and with accuracy.
A computer system-- A computer system is a manual and automated system computerized systems produce faster and accurate results. Computer provide faster calculating speeds and faster printing speeds and quick.retrieval of information.
A system-- A collective entity consisting of a group of elements which are inter-dependent, inter-related and inter -active. There are two type of system.
Concept of computer system-- In simple words, computer accept input and convert them into output. This conversion which is done as per the set of instruction is called the process.
Input -----> Process -----> output

A system-- A collective entity consisting of a group of elements which are inter-dependent, inter-related and inter -active. There are two type of system.
- A closed system.
- A open system.
Concept of computer system-- In simple words, computer accept input and convert them into output. This conversion which is done as per the set of instruction is called the process.
Input -----> Process -----> output
Input-- The user feed the data by Input device like keyboard mouse and other input devices Processing ---the processing done by CPU or central processing unit. which is also called the brain of computer system.
Output-- The user get the output after the processing on data. which is shows on output device monitor or printer in the form of soft copy or hard copy. or other output device.
In other word we also called the computer system is a group of multiple tasks to obtain one or more destination like wise computer also have different unit to perform their duties the different unit are computer system unit like hardware software and user also.along with these, two more units are these first is procedure and second is information or data.
Hard ware -- All mechanical electrical and electronic parts are called hardware.
Software-- A program which detects the computer to perform some specific job for data processing and to have necessary information is generated.
User--- The people who creates computerized data write programs to perform it we called them as user.
Output-- The user get the output after the processing on data. which is shows on output device monitor or printer in the form of soft copy or hard copy. or other output device.
