3. LAPTOP
Laptop computers, also known as
notebooks, are portable computers that you
can take with you and use in different
environments. They include a
screen, keyboard, and a track pad or
trackball, which serves as the mouse. Because
laptops are meant to be used on the go, they
have a battery which allows them to operate
without being plugged into a power outlet.
Laptops also include a power adapter that
allows them to use power from an outlet and
recharges the battery.
4. SUPER
COMPUTER
Extremely fast data processing-
oriented computer whose number
crunching power is (presently) measured in
hundreds of billions of floating point
operations(gigaflops). Supercomputers rely
on parallel processing technology and can
use only a few but very complex programs in
modeling economy behavior, nuclear
reactions, meteorological and neurological
phenomenon, etc. First supercomputer
(Cray-1) was made in 1976 by the
US engineer Roger Cray (1925-1996).
5. MICRO COMPUTER
The term microcomputer is generally synonymous
with personal computer (PC), or a computer that depends
on a micro processor. Microcomputers are designed to be
used by individuals, whether in the form of
PCs, workstations or notebook computers.A
microcomputer contains a central processing unit
(CPU) on a microchip (the microprocessor), a memory
system (typically read-only memory and random access
memory), a bus system and I/O ports, typically housed in
a motherboard
6. MAINFRAME
COMPUTER
Adata processing system employed mainly in
large organizations for various
applications, including bulk data processing, process
control, industry and consumer statistics, enterprise resource
planning, and financial transaction processing. Mainframes
use proprietary operating systems, most of which are based
on Unix, and a growing number on Linux. Over the years
they have evolved from being room-sized to
networked configurations of workstations and servers that
are an extremely competitive and cost effective platforms for
e-commerce development and hosting. Mainframes are so
