Operating System
Computer memory is extremely important to computer operation. Memory is responsible for a variety of tasks in the computer system. Computer Memory is the heart of your computer. The memory is often referred to as RAM, ( Random Access Memory). It is a internal storage area in the computer. Understanding computer memory is very important, the memory is what enables your PC to operate. RAM is the most common and most often used computer memory. There are numerous ways through which the computer memory could be classified: By location in the system,principles of operation and by function. Although the easiest method to classify the computer memory is to know the differences of the primary (or main) and secondary (or auxiliary) storage devices. The memory includes physical computer memory and a memory controller that physically accesses the computer memory.
Memory
Memory is the ability to retain data for a period of time. Memory can be built right into a system board, but it is usually attached to the system board in the form of a chip or module. Memory chips are tiny electronic circuits specially designed for storing data. Memory chips reside on the motherboard, or on a added memory boards inside your PC. Memory is very easy to install in computers, but be sure you buy the correct type of memory. Memory upgrades should be compatible with the memory already in your computer, and they must be compatible with the motherboard in your computer.
Ram
Computers generally come with no less than 256MB of memory for a basic computer. You can upgrade that to 512MB or more with the addition of one or two modules. Although older computers may not support that much. To installing CD-ROM drive you need about 740MB of hard drive space to copy CDs. Video cards have a built-in memory but they also consume your main system RAM. If you add a printer or scanner to your system, you should also consider buying more memory. Computer memory is always organized in a fixed manner. It is an electronic storage with no moving parts. Adding computer memory or upgrading computer memory is also one of the easiest computer upgrades. NOTE: No memory module is built to be universally compatible, so you need to find modules that are specifically made for your system.

Computer Memory Card - How Good Are They?
Computer cards typically include a battery to provide power to retain information in memory and for operations, such as input and output functions. Such computer cards may provide memory expansion for data storage. Memory cards generally consume only minimal amounts of current. Therefore, the battery used by memory cards may last several years. But during periods of time when a computer card is detached from a host computer, the computer card continues to draw current, if only for memory support, therefor draining the battery. When the computer card is hooked to a host computer, the computer can recognize the low voltage as an indication of low battery. In some cases a message may be displayed by the computer alerting you of a low battery. However, most computer cards are unable to independently alert a user of a low battery condition. Because the computer cards are small insize, the battery is usually very small, resulting in limited battery capacity, Because they are so small, typical computer cards are unable to independently alert a user to a low battery condition, the low battery condition could go unnoticed by the user for a long time during which the computer card is not hooked to the computer.
Card
With a computer having connectors with card slots and replaceable computer cards, Mounted in the card slots is a retainer device for securing computer cards. An anchor mounted on the connectors and a tie wrapped around a computer card mounting, the tie having the connector ends engaged with the clip to secure the card in the slot. The clip having prongs and the prongs being hooked with the sides of a connector and the anchor having at least one pair of anchor hooks, each of the hooks being located on opposite sides of the connector and engaged with one of the connector ends of the tie. The card retainer may also be used for any other electronic device where you have plug-in cards for which a problem of physical dislodgement of the card occurs. Many of these computer cards are manufactured in accordance with PCMCIA (Personal Computer Memory Card International Association) standards and are referred to as PCMCIA cards.

Why Increase Computer Memory
If you have ever been trying to run two or three programs at once on your computer and it seems to get really slow and sluggish, you may have a computer memory problem.
Computers have two kinds of memory, and both are very important if you accomplish many of your day's activities on a computer.
The first kind of computer memory is static computer memory. This is the amount of space you have to store things on your computer. When you save photos, video, music, documents and anything else on your computer, those files take up portions of your static computer memory.
The other kind of memory is RAM. This stands for Random Access Memory. This is essentially the space there is for things to be working on your computer. When you open Word, Internet programs, Photoshop and a few other programs, these are all pulling on your RAM computer memory to operate.
While the program itself is in your static memory, it requires space to work, and that is pulled from your RAM. It is much like having a game closet at home. All the board games are in the game closet, which is the static memory. When people decide to play games, there is only a certain amount of table space in the room where you can spread out and play. This is your RAM computer memory.
If you want to run a lot of programs or save a lot of video and audio files, you may need to expand both kinds of computer memory so your computer can keep up with your usage practices.
