1. Adding more RAM to a system will only help if the RAM that is currently installed is always filled to 100% and more space is needed.
2. A hard disk drive is quieter, more portable and has a quicker access time than a flash memory device.
3. Cache is like RAM but the one difference is that it is much ___________ to read and write from it as compared to RAM. This obviously speeds up CPU performance.
4. Although CPUs fetch instructions from RAM, there is another place they can get instructions from, called _______.
5. Describe how the CPU and RAM work together to make a tablet computer work and execute instructions/programs?
6. Both DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory) are types of RAM.
7. DRAM has a simpler construction compared to SRAM.
8. DRAM is more expensive than SRAM.
9. DRAM is used as the main memory, whereas on-chip caches are usually SRAMs.
10. Dynamic RAM is faster than Static RAM
11. Flash memory devices are cheaper and usually have a far higher capacity than traditional hard drives.
12. Flash memory gets its name from the fact that a whole block of data can be erased in a flash.
13. Flash memory is a type of permanent storage that is very convenient if you need to backup files or as a type of portable storage.
14. Most computer systems require secondary storage (this is different from Main Memory and RAM) in order to store files (like the operating system) even when the system is 'off'. This is referred to as ____________.
15. Flash memory is said to be solid state storage device because, unlike disk and CD drives, there are no moving parts.
16. Read/Write speed of a hard disk drive is faster than RAM.
17. Flash memory is used in which of the following devices?
18. The memory unit consists of RAM, sometimes referred to as primary or MAIN MEMORY. The key thing to remember is that: (which statement is correct?)
19. Flash memory will lose the stored data if it is not connected to a power source.
20. RAM cannot be removed from the PC.
21. Virtual memory is a section of volatile memory created temporarily on the storage (e.g. hard drive) drive. It tends to be created when ....
23. What is virtual memory?
24. When several programs run at the same time, the RAM can be full. Instead of closing programs, the operating system uses virtual memory to store some data.
25. Secondary storage is almost always (1)______________________ while Main Memory (like RAM) tends to be (2)____________________
26. Where is data stored when it is in virtual memory?
27. Some programs need a certain amount of RAM to run properly and companies will usually put this information on the box so you know before you buy.
28. The memory unit consists of RAM, sometimes referred to as primary or main memory. Unlike a hard drive (secondary memory), this memory is fast and also directly accessible by the CPU.
29. The use of virtual memory slows a computer because data must be mapped between virtual and physical memory, which requires extra hardware support for address translations.
30. Virtual memory frees applications from managing shared memory and saves users from adding more memory modules when RAM space runs out.
31. What are the two gates in the NAND flash drive?
32. What is stored in RAM?
33. Where does NAND flash memory derive its name from?
34. When using RAM - the data is saved when the electricity is switched off
35. An example of flash memory is an SD card
36. An internal hard disk uses magnetic technology
37. Virtual memory 'lives' in the hard disk
38. RAM is an example of secondary storage
39. RAM is also an example of flash memory
40. A computer is continuously 'paging' to the swap file - this is because there is not enough RAM.
