1. What are level-triggering interrupt?

RST 6.5 & RST 5.5 are level-triggering interrupts.

2. Give examples for 8 / 16 / 32 bit Microprocessor?

8-bit Processor - 8085 / Z80 / 6800;
16-bit Processor - 8086 / 68000 / Z8000;
32-bit Processor - 80386 / 80486

3. Why 8085 processor is called an 8 bit processor?

Because 8085 processor has 8 bit ALU (Arithmetic Logic Review). Similarly 8086 processor has 16 bit ALU.

4. What is 1st / 2nd / 3rd / 4th generation processor?

The processor made of PMOS / NMOS / HMOS / HCMOS technology is called 1st / 2nd / 3rd / 4th generation processor, and it is made up of 4 / 8 / 16 / 32 bits.

5. Define HCMOS?

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

6. What does microprocessor speed depend on?

The processing speed depends on DATA BUS WIDTH.

7. 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.

8. Is the data bus is Bi-directional?

The data bus is Bi-directional because the same bus is used for transfer of data between Micro Processor and memory or input / output devices in both the direction.

9. What is the disadvantage of microprocessor?

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

10. 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.

the basic architectural difference is that microcontroller has an programmable memory while it is not the case with microprocessors.
