State what the initials RAM stand for:
Random Access Memory
Explain why this type of memory is 'random access' and how this affects the speed at wich data can be retrieved from it.
RAM is a type of random access memory as you can change any party of the ram in any (random) order and you dont need to start at the first memory place, therefore is quciker so data can doesnt need to travel as far and so recievced at a quicker speed.
What is the main function of RAM in a computer?
The main function of RAM, in a computer, is to store data in the memory. RAM allows you to store read, rewrite, and change data without the need of the first memory location.
In what form is data saved in RAM?
Data in the RAM is saved as Binary.
How much data can be saved in each memory location?
1 byte or 8 bits or data can be saved in each memory location
The main RAM in a computer is made up of dynamic RAM or DRAM.
- Why is it referred to as dynamic?It is refered to as dynamic because it is memory that has to be constantly refreshed or it will lose its contents (-data it is storing)
List the differences between dynamic RAM and static RAM
- Static RAM does not need to be refreshed, Dynamic RAM does
- Therefore; Static RAM is quicker as it has no need to refresh and so supplys data to the CPU more rapidly
- Therefore; because of its benefits, Static RAM is more expensive
