  1. 1. Primary Storage By: Tikah Hawa Aisyah Nani Fatimah
  2. 2. DEFINITION <ul><li>Primary storage or internal memory is computer memory that is accessible to the central processing unit of a computer without the use of computer’s input/output channels. </li></ul>
  3. 3. FUNCTION <ul><li>Is used to store data that is likely to be in active use and is stored in location selected by virtual addressing into a physical address. </li></ul>
  4. 4. TYPES OF STORAGE <ul><li>Processor registers are internal to the central processing unit. Registers contain information that the arithmetic and logic unit needs to carry out the current instruction. </li></ul><ul><li>Cache memory is a special type of internal memory used by many central processing units to increase their performance or &quot;throughput&quot;. Some of the information in the main memory is duplicated in the cache memory, which is slightly slower but of much greater capacity than the processor registers, and faster but much smaller than main memory. </li></ul><ul><li>Main memory contains the programs that are currently being run and the data the programs are operating on. In modern computers, the main memory is the electronic solid-state random access memory . </li></ul>
  5. 5. EXAMPLES DEVICE <ul><li>Random Access Memory(RAM) </li></ul>
