Internal is a term used to describe
a device that is installed within the
computer. For example, a video card is
an internal device and a printer is an
external device. When referring to a
drive, an internal drive (e.g. internal hard
drive) is any drive inside the computer.

A switched-mode power supply (SMPS) is an
electronic circuit that converts power using
switching devices that are turned on and off at
high frequencies, and storage components such as
inductors or capacitors to supply power
when the switching device is in its non-
conduction state.

A motherboard is the main printed circuit
board (PCB) in a computer. The
motherboard is a computer’s central
communications backbone connectivity
point, through which all components and
external peripherals connect.

Once data has been written onto
a ROM chip, it cannot be removed and
can only be read. Unlike main memory
(RAM), ROM retains its contents even
when the computer is turned off. ROM is
referred to as being nonvolatile, whereas
RAM is volatile. ... A variation of a ROM is
a PROM (programmable read-only
memory).

Random-access memory (RAM) is a type
of computer data storage. A RAM device
makes it possible to access data in
random order, which makes it very
fast to find a specific piece of
information.

external device - Computer Definition.
Any peripheral device that is not housed
inside the computer cabinet. Monitors,
keyboards, mice and printers are
inherently external devices;
however, drives, network adapters and
modems may also be external.
See external drive, external modem and
USB adapter.

In computing, a computer keyboard is a
typewriter-style device which uses an
arrangement of buttons or keys to act as a
mechanical lever or electronic switch.
Following the decline of punch
cards and paper tape,
interaction via teleprompter-
style keyboards became the main input device
for computers.

The mouse, sometimes called a pointer, is a
hand-operated input device used to manipulate
objects on a computer screen.
Whether the mouse uses a laser or ball, or is
wired or wireless, a movement detected from
the mouse sends instructions to the
computer to move the cursor on the
screen in order to interact with files, windows,
and other software elements.

A scanner is a device that captures images from photographic
prints, posters, magazine pages, and similar sources for
computer editing and display. Scanners come in hand-held,
feed-in, and flatbed types and for
scanning black-and-white only, or color. Very
high resolution scanners are used for
scanning for high-resolution printing, but lower
resolution scanners are adequate for capturing
images for computer display. Scanners usually
come with software, such as Adobe's Photoshop product, that
lets you resize and otherwise modify a captured image.

The Centre offer Training and Coaching in
various computer software Courses. And
the credit directly goes to our teachers,
because they are the one who make the
students satisfied with their experience.
It's true that knowledge matters, but in
the meantime, we can't ignore the truth
that the experience of the person speaks
about his/her capability.Our professional
and experienced faculty is the backbone
of the Centre.
