"Hi, I'm Robert. Now, I'm going to show you what data compression is. Data compression is a way of saving or storing data in a very compact manner. An example would be MPEG or WinZip. What happens is if you want to send, let's say, an attachment, but it's too large, a lot of e-mail servers do not accept very large attachments, so you have to put it into a WinZipped file in order to transport that to the receiver of that e-mail. And WinZip allows you to make those files a lot smaller than the original files are. Data compression not only help users send out large files via e-mail, but it also helps them manage their storage much more efficiently because the files are not so large and, in essence, it saves them a lot of space on their storage."
