How to install Software Updates on your Mac
In order to keep your Mac secure and operating efficiently it is important that you always install software updates as they become available. These updates not only fix problems with applications and the operating system, but also fix security vulnerabilities that can be used by computer viruses to infect your computer. Unfortunately, many people feel that because they are using a Mac they are much more secure and thus may not be as diligent in updating their software as they would on a Windows machine where viruses are much more common.

What is a File Extension?
A file extension, or file name extension, is the letters immediately shown after the last period in a file name. For example, the file extension.txt has an extension of .txt. This extension allows the operating system to know what type of file it is and what program to run when you double-click on it. There are no particular rules regarding how an extension should be formatted other than it must begin with a period and have at least one character after it. For the most part, file extensions consist of three characters, which are typically letters or digits, that textually represent the type of file it is. Some examples of file extensions include .txt, .mp3, .jpg, and .gz, which represent text files, mp3 files, jpeg image files, and files compressed with the gzip program. As you can see, the actual extension name gives clues as to the type of file it is.
