interview questions on microcontroller 8051
and do you smoke ??? lol.
and do you smoke ??? lol.
Microprocessor is a program-controlled device, which fetches the instructions from memory, decodes and executes the instructions. Most Micro Processor are single- chip devices.What is a Microprocessor?
8-bit Processor - 8085 / Z80 / 6800; 16-bit Processor - 8086 / 68000 / Z8000; 32-bit Processor - 80386 / 80486.Give examples for 8 / 16 / 32 bit Microprocessor?
Because 8085 processor has 8 bit ALU (Arithmetic Logic Review). Similarly 8086 processor has 16 bit ALU.Why 8085 processor is called an 8 bit 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.What is 1st / 2nd / 3rd / 4th generation processor?
High-density n- type Complimentary Metal Oxide Silicon field effect transistor.Define HCMOS?
The processing speed depends on DATA BUS WIDTH.What does microprocessor speed depend on?
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.Is the address bus unidirectional?
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.Is the data bus is Bi-directional?
It has limitations on the size of data. Most Microprocessor does not support floating-point operations.What is the disadvantage of microprocessor?
