Memory
|
-Memory consists of electronic components that store instructions waiting to be executed by the processor, data needed by those instructions, and the results of the processed data.
|
|
|
Why a large capacity memory can help speed up a computer?
|
-Large capacity memory can hold more instruction, data and processed data.
|
|
|
List two type of memory
|
- Volatile
- Non volatile |
|
|
What are memory made of?
|
A memory chip is an integrated circuit (IC) made of millions of transistors and capacitors.
|
|
|
Volatile memory
|
Volatile memory is a type of storage whose contents are erased when the system's power is turned off or interrupted.Describe volatile memory.
|
|
|
Non -volatile memory
|
Non -volatile memory is a type of computer memory that can retrieved stored information even having been power cycled (turned off and back on).Describe non-volatile memory.
|
|
|
What is the other name for volatile memory?
|
Random Access Memory (RAM)
|
|
|
What is the other name for non-volatile memory?
|
Read Only Memory (ROM)
|
|
|
What is the difference between volatile and non-volatile memory?
|
Volatile memory does not lose its contents when power is removed while non-volatile memory loses its contents.
|
|
|
2 example of volatile memory
|
Static RAM
Dynamic RAM |
|
|
3 example of volatile memory
|
Dynamic RAM (DRAM pronounced DEE-ram) chips must be reenergized constantly or theylose their content.
Static RAM (SRAM pronounced ESS-ram) chips are faster and more reliable than any variation of DRAM, These chips do not have to be reenergized as often as DRAM |
|
|
example of non-volatile memory.
|
PROM - (programmable read-only memory
EPROM - (erasable programmable read-only memory) EEPROM - (electrically erasable programmable read-only memory) |
|
|
3 example of non-volatile memory
|
PROM - (programmable read-only memory) is a memory chip on which data can be written only once
EPROM - (erasable programmable read-only memory) is a special type of PROM that can be erased by exposing it to ultraviolet light EEPROM - (electrically erasable programmable read-only memory). Pronounced e-e-prom, an EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge |
