Random Access Memory

RAM is the best known form of computer memory. RAM is considered “random access” because you can access any memory cell directly if you know the row and column that intersect at the cell.

RAM is a memory device in which information can be accessed in any order. A computer’s RAM is its main memory where it can store data, programs, and application software, so the size of the RAM, measured in kilobytes or megabytes, is an important indicator of the capacity of the computer.

Random access memory or RAM most commonly refers to computer chips that temporarily store dynamic data to enhance computer performance. By storing frequently used or active files in random access memory, the computer can access the data faster than if it to retrieve it from the far-larger hard drive. Random access memory is also used in printers and other devices.

I would purchases the DIAMOND Xtreme Sound because it is less expensive but still offers similar features as the others. This one suits me because I would just like to buy a product that has high quality of sound, it doesn’t matter what other features it has with it. I also like how this product has karaoke support.
