22 Zip Drive Questions and Answers:

1 :: What is HCMOS?

High-density n- type Complimentary Metal Oxide Silicon field effect transistor.
Post Your Answer

2 :: Explain Is the address bus unidirectional?

The address bus is unidirectional because the address information is always given by the Micro Processor to address a memory location of an input / output devices.
Post Your Answer

3 :: What is NV-RAM?

Nonvolatile Read Write Memory, also called Flash memory. It is also know as shadow RAM.
Post Your Answer

4 :: Explain What is the difference between primary and secondary storage device?

In primary storage device the storage capacity is limited. It has a volatile memory. In secondary storage device the storage capacity is larger. It is a nonvolatile memory. Primary devices are: RAM / ROM. Secondary devices are: Floppy disc / Hard disk.

10 :: Explain Difference between static and dynamic RAM?

Static RAM:
No refreshing, 6 to 8 MOS transistors are required to form one memory cell, Information stored as voltage level in a flip flop.

Dynamic RAM:
Refreshed periodically, 3 to 4 transistors are required to form one memory cell, Information is stored as a charge in the gate to substrate capacitance.
