How to add more memory to the computer?

In recent years, the system memory seems to lose its value faster. That’s great news, since, more memory, means more programs and files can be opened at once. A typical memory can have 512Mb or 1 GB, but now, you can be increased to 2GB or even 4GB.

The hardest part of installing new memory is figuring out what kind of memory to buy. Memory is an alphabet soup of packages, pin configuration, types, and speeds. Many current systems are supplied with DDR2 SDRAM (Double Data Rate two synchronous dynamic random access memory) in 240-pin module DIMMs (dual in-line memory modules). Another type, DDR3 (Double Data Rate three) SDRAM, which roughly twice as fast as the standard DDR2 SDRAM, uses 260-pins DIMMs slots. All of these types of memory are available in different speeds.

To be absolutely sure about what kind of memory need, check the computer or motherboard documentation. The type of memory should be mentioned. Alternatively, opened the computer case and look at the memory chips for hints.
Once the type and amount of memory are found and needed, locate the sockets and remove the existing memory. The computer should be unplugged. Try to wear an antistatic wrist strap, and remove the case. In order to upgrade memory, the existing modules may have to remove. If the modules are held in place by plastic or metal tabs, push down on these tabs at the same time and the module should pop out. Then, try to install the new memory. Most modules (DIMMs) have two notches
