-= Memory Classifications =-

Two types of memory:
*Primary storage
*Secondary storage

Primary storage:
1. RAM(Random Access Memory)
>>this is power dependent,which means that if there is a power loss, the data that you've just saved will not be found if ever the current gets back. RAM is in a form of 'integrated circuits'.

2. ROM(Read Only Memory)
>>both data and instruction.This RAM is in a form of integrated circuits.

3. Cache memory
Acts as a buffer. It can be found inside the IC's.

4. Virtual memory
-extended memory
-dependent upon hard drive
-temporary
>>it is located inside your hard drive is set on operating system.

Secondary storage
1. Hard disc
>>it runs through a magnetic media
>>it is called 'hard' because it is "metallic"

2. Flash drives

3. CD and DVD's
>>There is also what we called Tertiary memory storage aside from primary and secondary memory storage.

Tertiary Storage
>>these are portables
•flash drive
•external CD-ROM drives
•external drives
•external hard disc- smaller hard disc
•flash memory card
•memory sticks
