5- (4 points) What is volatile memory? What is a non-volatilememory?

6- (6 points) (True/False) Look at the table in slide # 21 andanswer the following questions. Note that you should memorize thistable for future

. a) Size of SRAM is smaller than the size of DRAM.

b) DRAM is faster to access compared to SRAM.

c) DRAM is used to build Cache memory.

d) Flash memory is slower that SRAM and DRAM.

e) Flash memory is a volatile memory.

f) SRAM is a non-volatile memory.

7- (2 points) Order the following memory technologies accordingto access time (from fast to slow), and then according to price(from expensive to cheap): Tape, L1 Cache, DVD, L2 Cache, Blu-Ray,main memory, CD, Registers, Hard Disk.

8- (4 points) what is the reason for including L2 cache incomputer?s memory system?

9- (4 points) What is a memory controller? Where is it normallylocated? What type of operations does it manage?
