tangible (able to hold)

6. A motherboard is the central printed circuit board
(PCB) in many modern computers and holds many of the
crucial components of the system, while providing
connectors for other peripherals.
The motherboard is sometimes alternatively known as the
main board, system board, or, on Apple computers, the
logic board. It is also sometimes casually shortened to
mobo.

8. The central processing unit(CPU) performs most of the
calculations which enable a computer to function, and is
sometimes referred to as the "brain" of the computer. It is
usually cooled by a heat sink and fan.

10. Synchronous Dynamic Random Access Memory (SDRAM)
Double Data Rate(DDR)

11. A hard disk drive (often shortened as hard disk,
hard drive, or HDD) is a non-volatile storage device
that stores digitally encoded data on rapidly rotating
rigid platters with magnetic surfaces.

13. SATA - Serial Advanced Technology Attachment
IDE - Integrated Drive Electronics
The SATA standard defines a data cable with
seven conductors (3 grounds and 4 active
data lines in two pairs) and 8 mm wide wafer
connectors on each end
40-pin connectors generally attached drives to
a ribbon cable. Each cable has two or three
connectors, one of which plugs into an adapter
interfacing with the rest of the computer system.

15. 25 to 50 GB (single-layer)
50 to 100 GB (dual-layer)
4.7 GB (single-sided, single-layer)
8.5 GB (single-sided, double-layer)
700 MB (up to 80 minutes audio)

17. The keyboard is very simple to operate, and touch-
typing aside, most people can operate a keyboard
well enough. The keyboard is usually the primary
input device for a PC, which is why people can
become emotional when it breaks.

18. In computing, a mouse is a pointing device that functions by detecting two -
dimensional motion relative to its supporting surface. Physically, a mouse
consists of an object held under one of the user's hands, with one or more
buttons. (Although traditionally a button is typically round or square, modern
mice have spring-loaded regions of their top surface that operate switches
when pressed down lightly.) It sometimes features other elements, such as
"wheels", which allow the user to perform various system-dependent
operations, or extra buttons or features that can add more control or
dimensional input. The mouse's motion typically translates into the motion of
a cursor on a display, which allows for fine control of a graphical user
interface.

19. Printer - A printer is a peripheral which produces a hard
copy (permanent human-readable text and/or graphics) of
documents stored in electronic form, usually on physical
print media such as paper or transparencies. Many printers
are primarily used as local peripherals, and are attached by
a printer cable or, in most newer printers, a USB cable to a
computer which serves as a document source. Some
printers, commonly known as network printers, have built-
in network interfaces (typically wireless or Ethernet), and
can serve as a hardcopy device for any user on the network.
Individual printers are often designed to support both local
and network connected users at the same time.

20. A thin film transistor liquid crystal display (TFT-LCD) is a
variant of liquid crystal display (LCD) which uses thin film
transistor (TFT) technology to improve image quality
(addressability, contrast). TFT LCD is one type of active matrix
LCD, though all LCD-screens are based on TFT active matrix
addressing

21. Computer software, or just software is a general term
primarily used for digitally stored data such as computer
programs and other kinds of information read and
written by computers. Today, this includes data that has
not traditionally been associated with computers, such
as film, tapes and records. The term was coined in order
to contrast to the old term hardware (meaning physical
device) in contrast to hardware, software is intangible,
meaning it "cannot be touched".

23. The purpose of systems software is
to unburden the applications
programmer from the often
complex details of the particular
computer being used, including
such accessories as
communications devices, printers,
device readers, displays and
keyboards, and also to partition the
computer's resources such as
memory and processor time in a
safe and stable manner. Examples
are - Windows XP, Linux, and
Mac OS X.

24. Application software, also known
as software application,
application or app, is computer
software designed to help the user
to perform a singular or multiple
related specific tasks. Typical
examples are word processor/
spreadsheet, media players
database application.
