 RAM 

RAM or Random Access Memory is the amount of memory in your computer. It is the amount of data or programs that you are able to save temporarily. This is because the RAM only save information that is viewed when the system is on. It is important to check your manufacturer before you purchase a computer because a motherboard can only hold a certain amount of RAM and the more RAM you have, the more data you are able to see without making your computer slow down and freeze. There are two types of Random Access Memory. Static RAM, which is the more faster RAM because its clock cycle is much shorter and does not have to be refreshed constantly  The other is Dynamic RAM which is more commonly used because it is much cheaper. But, the negative part is that it has to be refreshed every few seconds. Your RAM is something that looks like a stick or a ruler. This can be 256MB, 512MB, 1GB, 2GB, 4GB, and 8GB.

Internal Hard Drive is the main storage area of the computer. This is also all the programs that are installed by the user. Modern Computers today contain several gigabytes of storage and provides the right amount of room for the average.

External Hard Drive are just for back-up programs that we hardly use regularly. This type of Drive can be easily moved from one computer to another. 

The Hard Drive is also very sensitive, and it can be easily damaged and it is costly to replace one.

You should buy one with at least 100GB of data so you can store more! The bigger the better! You should also buy one with more rotational speed (rpm) and a data transfer rate of at least 15MB. This will give you a fast computer and rapid-fire data!
