Computer Terms

Computer Terms

In 1822, when the first machine to even resemble a computer was invented, there were only a few terms to describe all the pieces and parts of the simplest version of the modern world’s most complex machine. Today, however, hundreds of terms have been added to the official vocabulary of the modern day computer. The following are terms that are commonly used as terminology for hardware, software, and everything in between. Some words are vender-specific, catering to programs such as Microsoft’s Windows. Others are able to be applied to every smart device with a circuit board.

In regards to both the technology many people have in their homes today and the massive network known as the World Wide Web, the terminology discussed in this list covers everything a lay person could possibly want to find out about how computers function and fit together. Information about viruses and other potentially deadly malfunctions are also provided in the text. It may be beneficial to think of the anatomy of a computer like the anatomy of a person. Much of the human microscopic anatomy can easily be compared to the undetectable codes that zoom around a computer’s “brain” every second it is awake.
