i) Which among following can be considered as most advanced ROM?
DRAM
EEPROM
RAM
PROM

ii)One byte equal to how many bits:

4  bits

 8 bits 

12 bits

 16 bits

iii) which among following is volatile?

ROM

EPROM

DROM

RAM

iv) where the result of an arithmetic and logic operation are storage?

 in accumulator

 in cache memory

 in Rom

 in instruction registry

v) why we need  to have secondary storage?

 storage large volume of data exceed the capacity of  main memory

 perform arithmetic and logical operation

 to give  power to the system too

 to help processor in processing
