Your computer

Computer
Sometimes abbreviated as 'puter, a computer is an electronic device that allows you to input data and have it stored, processed, or otherwise manipulated quickly and efficiently. Computers help make jobs that used to be complicated much simpler. For example, a user can easily write letters in a word processor and edit any portion of the letter anytime, spell check the letter, move text from another document into the letter, etc.

The first computer was called the ENIAC, which was built during World War II. Computers first utilized vacuum tubes and were very large (sometimes room size) and only found in businesses, schools, or governments. Later, computers began utilizing transistors as well as smaller and cheaper parts that allowed the common person to own their own computer.
