SECONDARY STORAGE

~ The disk drives in the computer are the most common form of secondary storage.

~ The disk drive is non-volatile and retains the information written to it after the power is turned off to the computer.

~ Because it is a mechanical device, the disk drive is much slower than primary storage devices.

CPU PROCESSING MAP

~ This is the CPU processing map.

~ This graph shows the connections between primary storage, secondary storage and tertiary storage.

~ RAM (random access memory) store data in a temporary period which allows the computer in running programs.

~ Secondary storage - the disk drive is non-volatile and retains the information written to it after the power is turned off to the computer.

PRIMARY STORAGE

~ Random access memory (RAM) is the main form of primary storage

~ The computer processor uses this RAM to hold code, perform computations and manage the operation of the machine because it is the fastest form of storing bytes of information.

~ Volatile storage unit ~ when the computer is turned off everything in RAM is    deleted.

~ Other types of primary storage include the processor cache and, for non-integrated graphics cards, the on-board memory that serves the graphics processing unit (GPU)

~ Commonly used in desktops nowadays is the dual in-line memory module (DIMM) form factor.

~ The latest memory technology as of date of writing is the Double Data Rate 3 Synchronous DRAM (DDR3 SDRAM). It has a high speed of up to 1600 MHz

~ It consumes less power and has better heat dissipation.

~ Ideal for recent technologies like Dual Quad core processors
