Hardware Components

Cache

A cache  is a component that transparently stores data so that future requests for that data can be served faster. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere.

 

 

RAM

Random-access memory (RAM) is a form of computer data storage. A random-access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order.

 

ROM

Read-only memory (ROM) is a class of storage medium used in computers and other electronic devices. Data stored in ROM cannot be modified, or can be modified only slowly or with difficulty, so it is mainly used to distribute firmware.

Processor

(CPU), an electronic circuit which executes computer programs, containing a processing unit and a control

Processing unit, in Von Neumann computer architecture, contains an arithmetic logic unit (ALU) and processor registers.
