22 Zip Drive Questions and Answers:

1 :: What is HCMOS?

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

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.

3 :: What is NV-RAM?

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

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.

5 :: Explain What does microprocessor speed depend on?

The processing speed depends on DATA BUS WIDTH.

6 :: Explain Why does microprocessor contain ROM chips?

Microprocessor contain ROM chip because it contain instructions to execute data.

7 :: Explain What is the disadvantage of microprocessor?

It has limitations on the size of data. Most Microprocessor does not support floating-point operations.

8 :: Explain What is the difference between microprocessor and microcontroller?

In Microprocessor more op-codes, few bit handling instructions. But in Microcontroller: fewer op-codes, more bit handling Instructions, and also it is defined as a device that includes micro processor, memory, & input / output signal lines on a single chip.

9 :: Design a FSM for vending machine now?

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

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.
