A computer is a programmable machine that was introduced as a tool to facilitate mathematical calculations many decades ago. Today it has become one of the most essential devices that you find in every office and in almost every house. It is now an important source to gain and share knowledge and information from and to all the parts of the world.
Modern computers are electronic and digital; they are more advanced and are being upgraded frequently. Many new versions of the operating systems are constantly being introduced for better applications and better functions for the users. They are always more advanced forms of the earlier versions.
The general components of all the computers are almost the same. The main characteristic of a computer is that it can respond to certain specific sets of instructions in a very well defined manner. The computer can execute all the prerecorded instructions. External devices like the frame and panel, wires, transistors, and the circuits are the parts of the hardware, and the data, instructions, programs, etc. of the computer are known as its software.
A computer is nothing but a machine that manipulates the data according to the type of instructions given to it. Technology has become so much advanced that a simple computer can now be fitted to a wrist watch and can function with the help of the watch battery. The capacity to store and execute the list of instructions and functions that are known as programs makes the computermore versatile and extremely distinguished.
Any type of numerical or data based problem can be solved within a second with the help of a computer. All the computers, in general, require the same hardware components: the memory storage devices, input device, output device, and the Central Processing Unit (CPU). The entire package of the hardware components enables the computer to work efficiently.
The software can be obtained according to your requirements. Computers are generally differentiated by their size and power. The most important feature that distinguishes the computer from other machines is that it can be programmed according to your use and need.
Let us discuss the application of computer from a business and organization point of view. Many multinational companies have been benefited with the help of the computer. In many companies they use two central processing units to create a multipurpose configuration so that the computer can divide the work load.
The computer can be made more useful by adding many other external devices such as the printer, fax machine, speakers, etc. With the help of the internet connection you can get access to the latest information and the events that are going on all over the world. All the latest updates and information appear on the screen of your monitor with a single click.
The computer is regarded as the most essential device to carry out our daily task more smoothly and with ease. If you do not have one, it is high time you got one, since it will benefit you in the various aspects of your work.
