The Alphabet of Computer Memory


Computer memory is called Random Access Memory (RAM). The information stored in RAM can be accessed randomly, rather than sequentially. This means that data can be found in any location at the same rate of speed. Other storage media, such as CD-Rom and hard drives, must wait while the drive spins to the correct location before the data can be accessed.
                                     
Computer memory is simply a storage area for the program code and the data that program uses. Computer programs use RAM to write and retrieve information, allowing for fast data retrieval and manipulation.


How Much RAM is Enough?
Simply stated, the answer is, as much as possible. Keep in mind, though, once you've reached a certain upper limit, which is determined by the computer program(s) used, investment in more memory will see a diminished return.

Hardware Cleaning Tips - 1

Case cleaning
Case cleaning keeps the appearance of the computer looking new. During cleaning, if ventilation locations are found, these can be cleaned helping the case keep a steady airflow to the computer, keeping components cool and in good working condition.
The plastic case that houses the PC components can be cleaned with a lint-free cloth that has been slightly dampened with water. For stubborn stains, add a little household detergent to the cloth. It is recommended that you never use a solvent cleaner on plastics.

Make sure all vents and air holes are hair and lint free by rubbing a cloth over the holes and vents. It is also helpful to take a vacuum around each of the hole, vents, and crevices on the computer. It is safe to use a standard vacuum when cleaning the outside vents of a computer; however, if you need to clean the inside of the computer, use a portable battery powered vacuum to prevent static electricity.
