There are sample Q. given below if you want complete set of Q. and there solution kindly look at file Here
Q. Define pipelining?
Ans: In 8086, to speedup the execution of program,
the instructions fetching and execution of instructions are overlapped each
other. This technique is known as pipelining. In pipelining, when the n th
instruction is executed, the n+1 th instruction is fetched and thus the
processing speed is increased.
Q. What is the function of the signal in 8086?
Ans: BHE signal means Bus High Enable signal. The
BHE signal is made low when there is some read or write operation is carried
out. ie . When ever the data bus of the system is busy i.e. whenever there is
some data transfer then the BHE signal is made low.
Q. What is assembler?
Ans: The
assembler translates the assembly language program text which is given as input
to the assembler to their binary equivalents known as object code. The time
required to translate the assembly code to object code is called access time.
The assembler checks for syntax errors & displays them before giving the
object code.
Q. What is loader?
Ans:The loader copies the program into the computer’s main memory at
load time and begins the program execution at execution time.
Q. Give the instruction
set of 8087?
Ans:
1. Data Transfer Instructions
2. Arithmetic Instructions
3. Comparison Instructions.
4. Transcendental Operations.
5. Constant Operations.
6. Coprocessor Control Operations.

Q. Define BIOS
Ans: The IBM PC has in its ROM
a collection of routines, each of which performs some specific function such as
reading a character from keyboard, writing character to CRT. This collection of
routines is referred to as Basic Input Output System or BIOS.
Q.What is interfacing?
Ans: An interface is a shared boundary between the devices
which involves sharing information. Interfacing is the process of making two
different systems communicate with each other.
Q.What is meant by interrupt?
Ans: Interrupt is an external signal that causes a
microprocessor to jump to a specific subroutine.
