A computer is fast operating and versatile machine that stores, retrieves, and processes data. It contains various electronic components, generically referred to as hardware. It follows a specific set of electronic instructions, called software. A personal computer, or microcomputer, is a small size computer that typically is designed to be used by one person at a time for programs that require relatively little computing power.
It is useful to know that there are other types of more powerful computers out there that can process information much faster and accommodate larger groups of people accessing the machine at the same time. A minicomputer is slightly larger and faster than the PC classification and capable of supporting up to hundreds of users simultaneously – these are very common in company settings.
A mainframe is faster than the minicomputer classification and can provide services to hundreds or thousands of users at the same time. Mainframes are frequently used to run multiple programs at the same time. At the top of the computer power pyramid is the supercomputer. A supercomputer is the fastest computer classification and is often used in research and simulation by hospitals, universities, and governments to accomplish a single, specialized task.
Personal computers are available in various sizes and models, depending in the specific use it is put to and the needs of the user. There are different types of personal computers, and it is important to use the one that best fits your working style and needs.
Some of the most common tasks a PC can help you with include: Budgeting and performing accounting tasks. Analyzing numeric information. Searching through lists or reports for specific information. Scheduling and planning projects. Creating illustrations. Gaming purposes. And, communicating by using electronic mail (email).
