What is the difference between multiproxessing and multitasking?

Multiprocessing (or parallel processing) refers to the use of two or more central
processing units, linked together, to perform coordinated work simultaneously. Instructions
are executed simultaneously because the available CPUs can execute different instructions
of the same program or of different programs at any given time. Multiprocessing offers dataprocessing
capabilities that are not present when only one CPU is used. Many complex
operations can be performed at the same time. CPU can function on complementary units to
provide data and control for one another.

Multiprocessing is used for nation’s major control
applications such as rail road control, traffic control, or airways etc.
Multi-tasking refers to the operating system’s ability to execute two or more of a single
user’s tasks concurrently. Multitasking operating systems are often contrasted with singleuser
operating systems. multi-tasking operating systems provide single users with
multiprogramming capabilities. This is often accomplished through foreground/background
processing.

What is spooling software and vedio controller?

Uses of Spooling Software
The purpose of spooling software is to compensate for the speed differences between
the computer and its peripheral devices.
Spooling utilities can also be used on the input side, so that programs and data to be
processed are temporarily stored in an input spooling area on disk.

Uses or video controller
It contains the video-dedicated memory and other circuitry necessary to send
information to the monitor for display on the screen.
Video controllers are used in displaying the graphics and images with more colours and
high resolution.

What is the difference between WAN & LAN?
 
Wide Area Networks (WAN) covers a large geographic area with various communication
facilities such as long distance telephone service, satellite transmission, and under-sea
cables. The WAN typically involves best computers and many different types of
communication hardware and software. Multiple user computers connected together are
spread over a wide geographic region facilitating communication channels between the
machines, usually furnished by a third party (for example, the Telephone Company, a public
data network, a satellite carrier).

Local Area Networks (LAN) covers a limited area. A typical LAN connects as many as
hundred or so microcomputers that are located in a relatively small area, such as a building
or several adjacent buildings. LANs use a shared physical media which is routed in the
whole campus to connect various systems. LANs use high-speed media (1 Mbps to 30 Mbps
or more) and are mostly privately owned and operated.
