SPECIFICATIONS OF MATERIALS AND COMPONENTS
A specification often refers to a set of documented requirements to be satisfied by a
material, design, product, or service. A specification is often a type of technical standard.
There are different types of technical or engineering specifications (specs), and the term is
used differently in different technical contexts. They often refer to particular documents,
and/or particular information within them. The word specification is broadly defined as "to
state explicitly or in detail" or "to be specific".
VGA (VIDEO GRAPHICS ARRAY)
Created way back in the 1980’s, the VGA connection cable
was the standard cable used to connect a computer to a
monitor. More recently, it has faded out of popularity due
to the gradual shift towards digital connections over analog.
Still, if you look on any video card or display apparatus,
there is a good chance you’ll see a VGA port.
DVI (DIGITAL VIDEO INTERFACE)
The DVI connection became the successor to VGA as
technology moved away from analog towards digital. Digital
displays, like LCD, proved to be higher quality, which soon
became the market standard for home pictures.
Unlocking of Difficulties
Monitor: An electronic device with a screen used for display (as of television pictures
or computer information)
Bandwidth: A range of radio frequencies which is occupied by a modulated carrier
wave, which is assigned to a service, or over which a device can operate.
Motherboard: The main circuit board especially of a micro computer.
Semiconductor: any of a class of solids (such as germanium or silicon) whose
electrical conductivity is between that of a conductor and that of an insulator in being
nearly as great as that of a metal at high temperatures and nearly absent at low
temperatures.

5. 3
IDE (INTEGRATED DRIVE ELECTRONICS)
IDE cables were used to connect storage devices to a
motherboard. If you’ve ever opened up a an old hard drive
then you likely know what an IDE connector looks like. It’s
the widecable that looks like a ribbon with more than 2
plugs.
HDMI (HIGH DEFINITION MULTIMEDIA INTERFACE)
In the past decade, high-definition broadcasts became the
new standard of what it means to be high quality. Unlike
VGA and DVI, HDMI sends both video and audio signals
together. The signals are digital only; thus, HDMI is only
compatible with newer devices.
USB (UNIVERSAL SERIAL BUS)
The USB connection is quite possibly the most pervasive
connection type intoday’s world. Nearly every form of
computer peripheral device keyboards, mice, headsets,
flash drives, wireless adapters, etc. — can be connected to
your computer through a USB port.
SATA (SERIAL ADVANCED TECHNOLOGY
ATTACHMENT)
Newer hard drives will likely use SATA ports over IDE ports.
In fact, SATA was designed to succeed IDE, and it has.
Compared to IDE, SATA provides higher data transfer
speeds. Your motherboard needs to be compatible with
SATA.
FIREWIRE
The purpose of FireWire is similar to that of USB: high speed
data transfer for computer peripherals. High bandwidth
devices, like printers and scanners, will benefit from
FireWire. For whatever reason, FireWire is not as
widespread as USB. FireWire cables come in two forms:
1394a (which has a transfer speed of 400 Mbps) and 1394b
(which has a transfer speed of 800 Mbps).
ETHERNET
Ethernet cables are used to set up local area networks. In
most cases, they’re used to connect routers to modems and
computers.
RESISTOR
A resistor is a passive two-terminal electrical component
that implements electrical resistance as a circuit element.
In electronic circuits, resistors are used to reduce current
flow, adjust signal levels, to divide voltages, bias active
elements, and terminate transmission lines, among other
uses.
CAPACITOR
Its function is to store the electrical energy and give this
energy again to the circuit when necessary. In other words,
it charges and discharges the electric charge stored in it.
Besides this, the functions of a capacitor are as follows: It
blocks the flow of DC and permits the flow of AC.
INTEGRATED CIRCUIT (IC)
An integrated circuit (IC), sometimes called a chip or
microchip, is a semiconductor wafer on which thousands or
millions of tiny resistors, capacitors, and transistors are
fabricated. An IC can function as an amplifier, oscillator,
timer, counter, computer memory, or microprocessor.
6. 4
DIODE
The most common function of a diode is to allow an electric
current to pass in one direction (called the diode's forward
direction), while blocking current in the opposite direction
(the reverse direction). Thus, the diode can be viewed as an
electronic version of a check valve.
TRANSISTOR
A transistor is a semiconductor with a solid and non-moving
part to pass a charge. It can amplify and switch electrical
power and electronic signals. Transistors are made of
semiconductor material with three or more terminals used
to connect to an external circuit.
