1.2 Memory

1. RAM

   • Volatile
     • Is computer memory that requires power to maintain the stored information; it retains its contents while powered on but when the power is interrupted, the stored data is quickly lost. Volatile memory has several uses including as primary storage
   • All Data is lost when the computer is turned off

2. CPU

   • ROM
     • ROM Is read only memory
       • Non-Volatile
         • Non-volatile memory or non-volatile storage is a type of computer memory that can retrieve stored information even after having been power cycled. In contrast, volatile memory needs constant power in order to retain data
   • Central Processing Unit
     • A central processing unit, also called a central processor or main processor, is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logic, controlling, and input/output operations specified by the instructions.

3. DRAM

   • Dynamic Random Access Memory

4. SRAM

   • Static Random Access Memory

5. Virtual Memory

   • Virtual Memory is a simulated memory that is written to a file on the hard drive

6. Flash Memory

   • a kind of memory that retains data in the absence of a power supply
