What is a computer memory?

Computer memory can refer to many types of memory on your computer, but usually refers to memory with random access (RAM). It is physically found on computer chips that are inserted on the computer's motherboard. RAM is rather electronic than mechanical; This means that it does not have moving parts and therefore access to data is very fast. Modern computers often have between 256 MB (megabytes) and 2 GB (gigabytes) of RAM, although of course there are computers with more or less RAM. RAM is also volatile, which means it is lost when the computer is turned off.

The dear nature of RAM stimulated the creation of another type of computer memory called virtual memory . With virtual memory, power slowing is only observed if you try to run a program whose files are in virtual memory. This slowdown is basically observed only when transition between programs. In this way, virtual memory often provides the EAPER Chalternative to RAM.

The third type of computer memory is cache . There are two types of cache. The primary cache or level 1 cache is built directly into the central processing unit (CPU) and ensures immediate availability of data that the CPU often needs. The secondary cache or level 2 cache is usually built on a memory chip, is located very close to the CPU and has a direct connection to the CPU through a reserved circuit. The secondary cache has greater capacity than the primary cache. The cache basically accelerates the speed at which the data moves from the main memory to the CPU.

registers form the fourth type of computer memory. These are units within CPUs that contain specific types of data, especially for the arithmetic and logical unit (ALU). The final group of computer memory is called flash. This is a solid, overwritten type of memory. Examples of Flashde BIOS memory and memory card. Like RAM they are, they arefor electronic and are not mechanical. They are also uninhabited and are therefore suitable for digital cameras, mobile phones and other miniaturized computers.
