Primary Storage Devices


RAM is a primary storage devicePrimary storage device are a component in the computer which stores data for a limited amount of time. The primary storage device oughtn’t be confused with the "primary storage drive", that is, the hard drive holding the operating system in the computer, normally "Local Disk (C:)".

The random access memory or RAM stores and offloads processed information at a high speed to the computer’s motherboard so it may be relayed to the northbridge, and for use by the GUI or graphic user interface, which allows users to access this information with their keyboard, monitor, mouse, etc.

Processor Cache
The processor, a.k.a the central processing unit or CPU, processes information in the computer. To do this, the CPU needs memory storage, which is called the "cache memory". This cache memory relays data at lightning speeds for processing in the cores of the processor. The memory, however, is a lot less smaller than the RAM. For instance, a processor will normally have 12 MB of cache, while the RAM might have as big as a 4 GB stick. However, the cache compensates for its size in sheer speed. The RAM will have, for instance, a speed of mostly 800 MHz, whereas the cache memory operates at 2.4 GHz.

Processor Registers
A processor register is the tiniest primary storage device. Normally, it holds from 32 to 64 bits, quite good enough for quite simple procedures like math calculations. However, processor registers are also the fastest primary storage device. They are mainly utilized by the processor for handling calculations in operating the programmes. The larger processes utilizing operating system and software files are kept in the cache memory.
