Ram is the acronym for 'random access memory' and is regularly calculated in megabytes. A Ram chip is a module that holds freshly accessed facts so that the central processing unit can have access to it. It is faster than reading from the hard drive and allows for easy access of recently stored data, information, and files. This means that all programs must be run straight through the Ram before they are usable.

There are two basic types of Ram, namely dynamic Ram and static Ram. A dynamic Ram is called so because it has to be constantly refreshed by the memory controller. The conjecture for refreshing is that the capacitors that hold the facts or data have a built-in leak that can only be stopped by refreshing the facts thousands of times in a second. This makes dynamic Ram slower and cumbersome compared to static Ram.

Static Ram is a type of random access memory that has a greater capacity for warehouse because it uses on-off switches instead of capacitors. However, static Ram is more costly compared to dynamic Ram because it is faster and can hold more information.

Usually, advanced versions of the dynamic Ram are used instead of using static Ram because of its high price. These versions consist of Fpm (fast page mode), Ecc (error correcting code), Edo (extended data output), and Sdram (synchronous dynamic Ram). Ecc Ram is a extra error-correcting Ram that is regularly used in servers.

Edo Ram, or extended data yield Ram, is an improvement of the former Fpm Ram. Data can be read faster and the distance of time that the yield data is valid is extended, which improves time coordination in the middle of the central processing unit and Ram, thus enhancing the performance.

The speed of a Ram is measured in nanoseconds, and the fewer the nanoseconds (ns), the faster the computer. Today we use 50 ns computers as opposed to the 180 and 150 ns that we used in the last decade.
