Frequently Asked Questions
Q1. What is Microprocessor?
Ans.
It is a program controlled semiconductor device (IC), which fetches, decodes and
executes instructions.
Q2. What are the basic units of a microprocessor?
Ans.
The basic units of a microprocessor are ALU, an array of registers and control unit.
Q3. What is Software and Hardware?
Ans.
The Software is a set of instructions or commands needed for performing a specific
task by a programmable device or a computing machine.
The Hardware refers to the components or devices used to form computing machine in
which the software can be run and tested. Without software the Hardware is an idle
machine.
Q4. What is assembly language?
Ans.
The language in which the mnemonics are used to write a program is called
assembly language. The manufacturers of microprocessor give the mnemonics.
Q5. What are machine language and assembly language programs?
Ans.
The software developed using 1's and 0's are called machine language programs.
The software developed using mnemonics are called assembly language programs.
Q6. What is the drawback in machine language and assembly language programs?
Ans.
The machine language and assembly language programs are machine dependent.
The programs developed using these languages for a particular machine cannot be
directly run on another machine.
Q7. Define bit, byte and word.
Ans.
A digit of the binary number or code is called bit. Also, the bit is the fundamental
storage unit of computer memory.
The 8-bit (8-digit) binary number or code is called byte and 16-bit binary number or code
is called word.
Q8. What is a bus?
Ans.
Bus is a group of conducting lines that carries data, address and control signals.
Q9. Why data bus is bi-directional?
Ans.
The microprocessor has to fetch (read) the data from memory or input device for
processing and after processing, it has to store (write) the data to memory or output
device. Hence the data bus is bi-directional.
Q10. Why address bus is unidirectional?
