P2 -Memory: purpose; random access memory (RAM); capacity; type, eg rambus dynamic (RDRAM), static
(SRAM), dynamic (DRAM), unified

2. So is a hard drive memory?
What is Memory?
Any physical device capable of storing information temporarily or permanently.
Random Access Memory (RAM), is generally what hardware experts mean when they talk about memory. Not Hard Drives, Flash Drives or Cache.
It’s volatile memory that stores information on an integrated circuit used by the operating system, software, and hardware.
So is a hard drive memory?

3. Memory Confusions and Differences
Technically Yes
Although both the hard drive and RAM are memory, it is more appropriate to refer to RAM as "memory" or "primary memory". RAM is volatile.
Hard Drive as "storage" or "secondary memory/storage”. Storage is non-volatile.
From now on when we refer to memory we mean RAM

4. What does it look like?

5. Why is memory important or needed for a computer?
Devices on a computer do not operate at the same speed and computer memory(RAM) gives your computer a place to quickly access data.
If the CPU had to wait for a secondary storage device like a hard disk drive the computer would be much slower.

6. How does it work?
You open a program such as your internet browser(Chrome, Firefox etc).
It is loaded from your hard drive and placed into RAM.
This allows that program to communicate with the processor at higher speeds.
Anything you save to your computer, such as a picture or video, is sent to your hard drive for storage.

7. Memory - Understand hardware technologies for game platforms – Task 1
Find out what kind of RAM is used in Xbox One, PS4, Xbox 360 and PS3 and a recent gaming PC. Include Type, amount and clock speed and bandwidth.
Put this information into a table.
As always include reference’s

8. Why is extra RAM useful for games?
RAM Capacity
Memory(RAM) comes in various sizes as we have seen.
4GB is generally considered good for general comput. 8GB recommended.
Currently for gaming it is considered that 8GB is the minimum needed and seen as 16GB as recommended.
Why is extra RAM useful for games?

9. RAM types
Static(SRAM): Does not need to be refreshed as long as the power supply is not cut off. It is faster compared to DRAM, consumes less power, has more transistors but is also more expensive. Cheaper DRAM is used in main memory while SRAM is commonly used in cache memory.
Dynamic(DRAM): DRAM requires the data to be refreshed periodically in order to retain the data. Memory in our computers/consoles use a version of this called Synchronous Dynamic Random Access Memory (SDRAM). Synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time.

10. GDDR vs DDR
DDR(Double data rate) SDRAM(Synchronous Dynamic Random Access Memory):
Standard used for most PC’s. Currently on type 4(DDR 4).
Graphics DDR SDRAM (GDDR SDRAM):
A high bandwidth  interface designed for use in graphics cards, game consoles and high-performance computation. Superior to standard DDR but expensive in comparison. Currently on type 5(GDDR 5)
