1.2 memory

1. Flash Memory

   • Flash Memory- is a type of memory that is a solid state and has no moving parts.
     • a memory stick is an example of this.
     • flash memory maintains data in the absent of power supply

2. ROM

   • ROM- Read only memory and this is Non Volatile
     • Non Volatile- Doesn't lose data when the device is turned off

3. Cache

   • Cache- Cache is another type of storage and it is close to the CPU however it doesn't contain a lot of memory
     • it is faster than RAM
     • Cache is volatile

4. Virtual Memory

   • Virtual memory is an area of secondary storage that is used like RAM
     • it is temporary storage
     • it is located on the hard drive
       • When the Hard drive is full you can no-longer do things such as copy
       • Magnetic storage device
     • Virtual memory is needed to let more memory in then there is in the system
     • Hardware which stores data other than RAM and ROM

5. Register

   • Register-A CPU register is one of a small set of data holding places that are part of the computer processor. A register may hold an instruction, a storage address or any kind of data

6. Solid State

   • Solid State- this is NO moving parts and it uses flash memory
     • because it has no movement it is very hard to hack
     • solid states are faster than Hard disk because there is zero latency

7. RAM

   • RAM- Random access memory and this is volatile
     • Volatile- Gets emptied when the power is turned off.
     • very expensive
