RAM (Random Access Memory)

What is RAM -Random Access Memory- ???


Random Access Memory (RAM) is the "working memory" in a computer. Additional RAM allows a computer to work with more information at the same time which can have a dramatic effect on total system performance.

Every time you open a program, it gets loaded from the hard drive into the RAM. This is because reading data from the RAM is much faster than reading data from the hard drive. Running programs from the RAM of the computer allows them to function without any lag time. The more RAM your computer has, the more data can be loaded from the hard drive into the RAM, which can effectively speed up your computer. In fact, adding RAM can be more beneficial to your computer's performance than upgrading the CPU.


To check how much RAM a Windows computer has, open the "System" Control Panel. This can be done by right-clicking "My Computer" and selecting "Properties..." To view how much RAM is installed in a Macintosh computer, select "About This Mac" from the Apple Menu

Laziness (also called indolence) is a disinclination to activity or exertion despite having the ability to do so. It is often used as a pejorative; related terms for a person seen to be lazy include couch potato,slacker, and bludger.

Despite Sigmund Freud's discussion of the pleasure principle, Leonard Carmichael notes that "laziness is not a word that appears in the table of contents of most technical books on psychology... It is a guilty secret of modern psychology that more is understood about the motivation of thirsty rats and hungry pecking pigeons as they press levers or hit targets than is known about the way in which poets make themselves write poems or scientists force themselves into the laboratory when the good golfing days of spring arrive."^[1] A 1931 survey found that high school students were more likely to attribute their failing performance to laziness, while teachers ranked "lack of ability" as the major cause, with laziness coming in second.

Secondary Storage

Secondary storage device

Alternatively referred to as external memory and auxiliary storage, secondary storage is a storage medium that holds information until it is deleted or overwritten regardless if the computer has power. For example, a floppy disk drive andhard drive are both good examples of secondary storage devices. As can be seen by the below picture there are three different storage on a computer, although primary storage is accessed much faster than secondary storage because of the price and size limitations secondary storage is used with today's computers to store all your programs and your personal data.

Finally, although off-line storage could be considered secondary storage, we've separated these into their own category because this media can be removed from the computer and stored elsewhere.
