There is so much specialized terminology related to computers that it's impossible for the average person to know what they mean and refer to. Fortunately, it's also unnecessary to know all this terminology before you jump on the Internet and do whatever it is you want to do.

That brings us to the computer term of the day—localhost.

If you're not a network administrator and/or you don't run a help desk, do you need to know what localhost means? The answer is no.

If you want to impress the IT guys who come to fix your computer or get your network working again, you may want to know. (Or if you're simply curious and open to learning new things.)

One thing's for sure—based on the definitions you'll see out there—for being so innocent sounding, localhost has to be the most difficult term to explain.
