Computer
A term that originally was given to humans who performed numerical calculations using mechanical calculators such as the slide rule and abacus that was later given to a mechanical device that was planned on being used to replace these humans. A computer is not an acronym, is sometimes abbreviated as comp or 'puter and is an electronic device that allows you to input data and have it stored, processed, or otherwise manipulated and if necessary output that data in an easy to read format.
Computers help make jobs that used to be complicated much simpler. For example, a user can write letters in a word processor and edit any portion of the letter anytime, spell check the letter, and move text from another document into the letter, etc. This is just one of millions of different things a computer is capable of doing.
The first computer was called the ENIAC, which was built during World War II. These early computers used vacuum tubes and were very large (sometimes room size) and only found in businesses, Universities, or governments. Later, computers began utilizing transistors as well as smaller and cheaper parts that allowed the common person to own their own computer. This history of computers and related topics can be found on our history page.
Today, most computers are often comprised with some or all of the below components.
