Wired Methods of Connecting to Devices
Fibre Optic Cable
Extremely fast data transfer speeds, 100Gbps is generally the max speed for a cable however it is theoretically possible to be even faster. Excellant data transfer range over 100km is possible. Very secure, cannot be interfered or tapped to intercept data.
Very expensive to operate and maintain, while not technically expensive for per-distance basis.
Fibre Optic is a connection method where data is transferred through pulses of light. Cable is made of tiny reflective plastic fibres. The light pluses bounce off the reflective surface to transmit down the cable.
SATA
Extremely fast connection type, capable of 6Gbps. Highly compatible, all internal storage devices will have a SATA connector.
SATA has an extremely short range, not an issue as it is internal, however eSATA only has 2 metres of range. Requires an additional power connector.
Serial ATA method of connecting storage devices to computer, current standard is SATA III
HDMI
HDMI has an extremely high bandwidth of 18Gbps, This allows for 4k quality at 60Hz. Transmits auido with the video signal.
HDMI has no locking mechanism and can accidently get knocked out. Not capable of high refresh rates like 165Hz.
More modern method of connecting display devices. Capable of high quality resolutions and is quite a small connector which is great for modern laptops. Display is an alternative capble of high resolution and higher fps.
VGA
Compatible with older components. Has a locking mechanism built in to ensure the cables remains securely connected.
Transmits analogue data instead of digital, signal degrades. Cannot handle higher resolutions, however some can run HD. Cannot transport audio signal with the video, requires additional cable for audio.
Visual Graphics Array, is connect for display devices like monitors and projectors. Now being quickly replaced with DVI, HDMI and DisplayPort.
Ethernet
Very reliable connection method, bandwidth is not split across mutliple users. Can transfer data over 100 metres, speeds up to 1000Mbps. Highly compatible.
Compared to Wi Fi it has extremely limited mobility requiring constant connection. Extremely limited comptability with mobile devices. Not great over huge distances.
This is a form of UTP/STP cable that is used to transmit data between IT systems. Used to cerate LAN
USB
Fast transfer speed on 3.0 version. Provides power. Highly compatible.
Relatively short range. Maxium practical length of USB 3.0 is 3 metres.
Universal Serial Bus, commonly used wired connection method, used for most peripheral devices.
