      This website goes pretty in-depth on how RAM works. Showing you animated graphs and ultra detailed wording and process steps. The definition this web site uses is as follows “…because you can access any memory cell directly if you know the row and column that intersect at that cell”. This website seems geared to people who have some knowledge with ram because thw verbage used in this example is very expert like for example “DRAM works by sending a charge through the appropriate column (CAS) to activate the transistor at each bit in the column”. A little intimidating and overwhelming.

      This website explains a lesser detail but is more novice friendly. It tells us that the RAM is the computers main memory where data is stored, it also says that the size of the ram is important when choosing the right product for your computer.

      The last website is a well known website that we all use today, I feel that this is the easiest most efficient way you can explain what is RAM and how it works. Wiki says that RAM is a type of “computer data storage” It also says that random means that “..the piece of data can be returned in a constant time”. That is where the word “random” comes into play. Out of the three website wiki is the only one that explains about the volatile nature of the RAM, saying what we learned in class is that if the power is turned off that the information will and can be lost forever. Although the computer RAM is the main type of ram we think of, that it is not the only type of “volatile” memory used in the computer world.
