An Analysis of Different Types of Computer Cables and Connectors
A computer has many parts that are connected to each other
via cables, especially external hardware that make use of external cables. Different
types of cables serve their own purposes and have little to no compatibility
with connectors that are not meant to connect those cables, for every cable has
its own unique connecting pin. Here is an analysis of different types of
computer cables and connectors:
VGA Cable
VGA stands for video graphics array. The main task of this
cable is to connect the computer motherboard with an external monitor that can
display images sent to it by the computer. It is used to transfer video
signals, and comes in male and female type connectors. Modern computers use
more advanced connections, so VGA connectors are slowly becoming uncommon.
HDMI Cable
HDMI stands for high definition multimedia interface. It is
the modern replacement for VGA cable, for unlike VGA, HDMI cables can transmit
both video and audio signals at very high speeds, making it perfect for high
definition content such as 2k or 4K video. It is a standard connector port in
computers and televisions, and come in male and female HDMI connection
variants. HDMI cables come in regular and mini variants, which shall require an
adapter or a supporting cable to connect to a relevant HDMI out/in device.
DVI Cable
DVI stands for digital visual interface. A connection
standard that lies between VGA and HDMI in terms of features and speed of data
transmission, DVI cables can project videos up to 2K resolution, but cannot
transmit sound data. They are commonly used as connectors in computer monitors
and projectors.
PS/2 Cable
PS/2 stands for personal system/2, and was originally
developed by International Business Machines (IBM) for connecting mouse and
keyboards to personal computers. PS/2 ports come in 2 variants: purple
connector pin for keyboard and green pin for mouse. It is an old standard for
mouse and keyboard connectivity, and are rare to find in modern computers as
mouse and keyboards now make use of USB ports for connectivity.
USB Cable
USB stands for universal serial bus, and is used for high
speed data transfer depending on the type of USB port in question. Major
functions of USB ports are connecting storage devices, input devices such as
mouse, output devices such as scanners, wireless adapters such as external WI-Fi adapter and as data transfer port between computers and electronics such
as smartphones and portable music players. Computers today come in USB 2.0 and
3.0 variants, with a USB 3.0 port signaled in blue outline inside the port.
Ethernet Cable
Ethernet cables are used to connect a computer to a network
device to enable internet connectivity. Although Wi-Fi is now an omnipresent
feature in almost every computer, Ethernet is still as important as it was over
a decade ago because wired internet is highly reliable and offers faster speeds
than wireless internet.
3.5mm Audio Cable
3.5mm audio jacks were an industry standard for every
computer, smartphone and portable music players up to a few years ago, but is
slowly losing relevance due to many major manufacturers opting to phase out
3.5mm connectors in favor of USB-C connectors and wireless earphones via
Bluetooth.
