how to prepare for an interview Operating System
In this article, we will be discussing the questions and answers about the operating system, which habitually asked in interviews.
What is it Operating System?
The operating system is a
software program that facilitates computer hardware to interconnect and
operates with the computer software. It is the most prime part of a computer
system. Without an operating system, a computer is just like a box.
What
is the leading purpose of an Operating System?
There are two leading purposes
of an operating system.
1.
It maps out to make sure that a computer system
executes well by managing is computational activities.
2.
It comes up with an environment for the development
and execution of programs.
Define
Deadlock?
Deadlock is a comprehensive
circumstance where two processes are hanging fire for each other to total so
that they can tackle. But this circumstance causes droop for both of them.
What is Kernel?
The kernel is a computer
program at the nucleus of a computer's operating system that has complete
command over everything in the system. It is the segment of the operating
system code that is always occupant in memory and prerequisite interlinkage
between hardware and software constituents.
What
do you mean by SMP?
SMP refers to symmetric
multi-processing. It is the most typical kind of multi-processor systems. In
this system, each computer runs an equivalent copy of the operating system, and
these copies converse with one another as desired.
What
is the Real-Time System?
When rigid-time demands have
emplaced on the operations of the processor, then the real-time system is used.
It contains well-defined and fixed time constraints.
What
is Piping?
It is the procedure of using
the output of one plan as an input to another. For example, in its place of
sending the catalog of a folder or constrains to the key screen, it can be
piped and sent to a file to create a hard copy.
Define
the Bankers' Algorithm?
Banker’s algorithm is one
shape of deadlock eluding in a system. It gets its forename from a banking
system wherein the bank never allocates in circulation cash in such a move that
it can no longer gratify the needs of all of its customers.
Define
Virtual Memory?
Virtual memory is a beneficial
memory management method that enables the process to carry out outside of
memory. This method is exceptionally used when an executing plan cannot fit in
the corporeal memory.
