RAM is an abbreviation for 'random access memory' and is usually calculated by megabytes. A RAM chip is a module that stores newly acquired information so that the central processing unit can access it. Faster than readable on a hard drive and allows easy access to the most recently stored data, information, and files. This means that all programs must be run on RAM before they can be used.
There are two basic types of RAM, namely flexible RAM and static RAM. Flexible RAM is so called because it must always be updated with the memory controller. The reason for the renewal is that capacitors that capture information or data have a built-in leak that can only be stopped by updating the information thousands of times per second. This makes the flexible RAM easier and harder compared to static RAM.
Fixed RAM is a type of random access memory with great storage capacity because it uses switched switches instead of capacitors. However, Stable RAM is more expensive compared to flexible RAM because it is faster and can hold more information.
Typically, advanced versions of flexible RAM are used instead of using standing RAM due to its high cost. These versions include FPM (quick page mode), ECC (error correction code), EDO (extended output), and SDRAM (compatible RAM flexible). ECC RAM is a special error-correcting RAM commonly used on servers.
EDO RAM, or RAM for extended data extraction, is a development of standard FPM RAM. Data can be read quickly and the duration of valid output data is extended, which improves the time interaction between the central RAM processing unit, thereby improving performance.
RAM speed is measured in nanoseconds, and when nanoseconds (ns) are reduced, the computer is much faster. Today we use 50 ns computers as opposed to the 180 and 150 ns we have used over the past decade.
