RAM


RAM comes from its acronym in English: Random Access Memory, and is a small memory of fast features that the computer uses to work internally and store data to which it needs quick access. The random access means that you can access any part of the memory instantly without having to read the previous ones first. The other type of memory is called sequential, which is obviously much slower, because before reading that third giga must access the first and second. Imagine an audio tape or a CD, which turns on itself and moves forward and backwards to read one or another part. In RAM, access is immediate, you do not have to go forward or backward, but go directly to the site where the information is indicated. There are several types of RAM, according to their objective, and they have also evolved over time as computing has done. In general we have two main types, the DRAM (Dinamic RAM) on the one hand, which is slower because it is dynamic, and therefore must be refreshed continuously, wasting time on it. It is in general the main memory, because it is cheaper. On the other hand we have the SRAM (Static RAM), which does not need to be cooled, being much faster, but also more expensive to use transistors instead of capacitors. In addition to these there are many more types, and can also be differentiated according to the memory available, such as SIMM (Single Inline Memory Module), which are characterized by putting the memory modules in a row, the DIMM (Double Inline Memory Module), which they put them in two rows (and they are faster) ..., etc.
