b) Laser Printer [5
+5]
Answer.
a) CRT Monitor
The traditional output device of
a person computer has been the CRT (Cathode Ray Tube) monitor. Just like a
television set (an older one, anyway) the CRT monitor contains a large cathode
ray tube that uses an electron beam of varying strength to “paint” a picture
onto the color phosphorescent dots on the inside of the screen. CRT monitors
are heavy and use more electrical power than flat panel displays, but they are preferred
by some graphic
Q2. Explain
Workstations. [5]
Answer.
Workstations
Workstations are special single
user computers having the same features as personal computer but have the

a global state.
Q5. What are the
five major activities of an operating system in regard to process management?
[5]
Answer.
Major activities
of an operating system in regard to process management
The operating system manages many
kinds of activities ranging from user programs to system programs like printer
spooler, name servers, file server etc. Each of these activities is
encapsulated in a process. A process includes the complete execution context
(code, data, PC, registers, OS resources in use etc.). It is important to note
that a process is not a program. A process is only ONE instant of a program in
execution. There are many processes can
