Is it better to turn my computer off or leave it on all the time?

This is one of those questions where there is no single right answer. In other words, it depends on how you use your computer.

There are at least three situations that force you to leave your computer on 24 hours a day:

• You are on a network, and the network administrators back up files and/or upgrade software over the network at night. If that is the case, and you want your machine backed up or upgraded, then you need to leave it on all the time.
• You are using your machine as some sort of server. For example, There are a machine that creates the images for the How Webcams Work article. It needs to be on 24 hours a day. If your machine acts as a file server, print server, Web server, etc., on a LAN (local area network) or the Internet, then you need to leave it on all the time.
• If you are running something like SETI@home and you want to produce as many result sets as possible, you need to leave your machine on all the time.
