memory- data storage space inside a computer. Memory usually refers to data stored using a chip or chips, while the term storage refers to data maintained on disks or tape. All computers are equipped with what is known as physical memory, called the main memory or Random Access Memory (RAM). RAM is the same as physical memory. In the recent past, the standard memory capacity for an off-the-shelf Personal Computer was anywhere from 16 to 32 megabytes of RAM. Today, many stock computers come equipped with 64 to 128 megabytes of RAM and often more.
memory leak- a glitch that causes a program to use more and more memory until it finally causes a crash of the system.
Memory Stick- a flash memory card from Sony designed for digital storage on cameras, camcorders and other handheld devices. Introduced in 1998 with 4 and 8MB capacities, storage has increased to 2GB with the Memory Stick PRO format. The 2" long modules are about a tenth of an inch thick (.85 x 1.97 x .11").
menu- a list of choices or commands a computer has available on a screen. The menu options may be accessed by pointing the mouse cursor over the desired command and left clicking. Usually this will prompt a list of choices to appear. From here, the user clicks of one of the items to execute the particular command.
menu bar- similar to a toolbar except the options or commands appear as a horizontal line of words including File, Edit, View, etc. at the top of a computer screen rather than icons or symbols.
merge- to combine information from one file with information of another file in a manner that maintains the inherent order (often alphabetical or numerical) of each.
message box- the same as an alert box, a small dialog box appearing on a computer screen that notifies the user of a changing condition with the application. For example, a message box might appear telling the user that the program is running low on memory and suggest closing down other applications to free up resources. The message box will disappear only after the user acknowledges the message by clicking on one of the options offered.
meta- a prefix used in computer science meaning “relating to” or “based on.” For example, a metadirectory would be a directory relating to, or about directories. More simply put, a directory of directories.
meta tag- HTML information describing a Web page or document. In addition to information about the enterprise that created the page, important keywords are written as meta tags, which are designed to be found when a search engine seeks these words entered by a user. The clever use of meta tags used to associate keywords to a Website can significantly increase traffic to the site. To take a look at HTML code and meta tags while online, click on “View” in the menu bar in Microsoft Explorer, then select “Source” and click again.
MHz- see Megahertz.

A few words from Tech Support:
"If the mouse cable keeps knocking down the framed picture of your dog, lift the computer and stuff the cable under it. Mouse cables were designed to have 45 lbs. of computer sitting on top of them."
