Wired connections and their uses
Ethernet and Telephone communications (CAT5)
Ethernet is a form of wired communication that is used to connect devices on a local area network (LAN)
It allows computers, printers and other networked devices to communicate through a wired connection (cable).
Advantage: Versatile and widely available, cheap compared to other networking options.
Limitations: Only useful over shorter distances, more susceptible to interference than other wired techniques such as fibre.
Fibre Optic cables
Telephone and Internet cables, cable television and computer networking.
Advantages: Improve security as the cable cannot be tapped, can be used over long distances, high data transfer rate.
Limitations: Very expensive, specialist skills needed to install.
VGA
Analogue connection of video display equipment, such as projectors, CRTs or LCDs.
Advantages: Universally used on high-resolution display equipment, low-cost cabling.
Limitations: Cumbersome cabling, signal affected over distance (noise), no DRM (digital rights management).
HDMI
Digital connection of both video and sound from devices to display equipment.
Advantages: Capable of 8K (and beyond) resolution, used in computing and entertainment.
Limitations: Limited length, cabling and technology is more expensive than analogue equivalents such as VGA.
USB/Firewire
Connecting equipment and peripherals, such as printers, scanners, input devices and cameras.
Advantages: High speed capability, can connect multiple devices, Backwards compatibility
Limitations: Limited distance, Limited power supply.
Coaxial
All types of data communication, commonly used in television cabling.
Advantages: Less susceptible to interference than UTP/STP so works over longer distances, Cheap, though not as cheap as UTP/STP.
Limitations: Thickness of the cable makes it difficult to work with, limited bandwidth.
