Computer is defined as an electronic computing device characterized by high speed and accuracy. It can handle data processing, storing, and retrieval following set of instruction and orders to get required results. Computer can process the operations according to the set of instruction and orders which are logically and algorithmically coordinated to solve a specific problem to get useful information and result.
Computer is a programmable machine. This means it can execute a programmed list of instructions and respond to new instructions that it is given. Today, however, the term is most often used to refer to the desktop and laptop computers that most people use. When referring to a desktop model, the term “computer” technically only refers to the computer itself — not the monitor, keyboard, and mouse. Still, it is acceptable to refer to everything together as the computer. If you want to be really technical, the box that holds the computer is called the “system unit.”
Some of the major parts of a personal computer (or PC) include the motherboard, CPU, memory (or RAM), hard drive, and video card. While personal computers are by far the most common type of computers today, there are several other types of computers. For example, a “minicomputer” is a powerful computer that can support many users at once. A “mainframe” is a large, high-powered computer that can perform billions of calculations from multiple sources at one time. Finally, a “supercomputer” is a machine that can process billions of instructions a second and is used to calculate extremely complex calculations.
PURPOSE OF USING COMPUTER
Computer is used to preform calculations, store data, gather information, retrieve data and process information in which help the people like easier and faster.
When the internet is made computer helps prosper education, and maximize communication through the use of email. Computer also serves as additional
entertainment as programmer developed application that fulfills the community desire.
The impact or computers on society
Modern computer provides the society needs it is the fact that our world is in era of computer and continue to innovate. Computer technology has brought about, many changes in the way we live in this present society.
What are the advantage and disadvantage of computer?
Computer help our daily lives more easy it allow people across the globe to communicate with each other, no matter at what time, via the use of email it is also helpful look up information directly, instead of the use of searching through books it can back-up copies of work can be made easily, without having to re-write everything. Computer also allow people work from home, and spend more time with their families because of this. People with disabilities whom can’t write, can get software that allows them to speak and it types it on the screen.
Computer is very useful but it can also be harmful as the computer continued innovates lots of people abuse on using it some of them use it and commit crime, hacking is a process of accessing data from another computer without permission. Piracy let you have instant access and copy in any application provided in the internet without proper purchasing.
