Wired methods of connecting devices
USB
Universal Serial Bus:
Commonly used, usually used to connect peripheral devices to all kinds to a computer
Used exclusively for majority of peripherals such as webcams, canners, good quality audio, external storage, mouse, keyboard
Advantages
Connecting multiple peripherals
Provides power to the device connected, no need for additional power supply
Fast data transfer speed: 5Gbp, HD movie from HDD to computer in just seconds
Highly compatible with devices, pretty much every computer system has a USB port
Disadvantages
Short range, maximum practical length is just 3 meters
SATA
Serial ATA:
Method of connecting storage devices to a computer
Advangtages
fast data transfer speed, Gbps
Highly compatible with devices, all internal storage devices have a SATA connector
Disadvantages
Short range, not much of an issue since it is used internally but externally the max is only 2 meters
No power to peripheral so devices like a hard drive need additional power tn order to run
Predominantly used internally in a computer and most common connector for internal storage devices, does exist for external but not common
VGA
Visual Graphics Array: Connector used for display devices such as monitors or projectors. Used to be common but now more rare
Advantages
Legacy compatibility, older technologies, often seen in the workplace, will still be compatible with it
Secure looking, has locking mechanisms built in to ensure the cable remains securely connected
Disadvantages
Analogue transmission, signal degrades easily due to things lie length and analogue to digital conversion
Low resolution, cannot handle same quality resolution as other digital methods
Video only, cannot transfer an audio signal along with the video signal. Separate audio cables for sound
HDMI
Connects display devices such as monitors to a computer. Popular and capable of extremely high-quality resolutions + small which is great for modern laptops
Advantages
fast data transfer speed, high bandwidth of 18gbps. Allows it to output 4K quality at 60Hz. very high qualtiy
Transmits audio and video, separate cables are not needed
Disadvantages
No secure locking, cables can fall our of the device accidentally
Ethernet cable
Form of UTP.STP that is used to transmit data between IT systems. Used to make LAN in workplaces to share resources. Also can be used for internet access
Advantages
Good range, it can transfer data 100 meters at 1000Mbps
Highly compatible with devices
Reliable connection, not a shared medium, bandwidth not split and not very susceptible to interference
Disadvantages
Limited mobility, need physical wire from computer to connection point
Poor compatibility with mobile devices, less common in laptops too
Some range limitations, not incredibly long so it can't transfer data over very large networks
Fibre optic cable
Connection method where data is transferred through the use of pulses of light.
Cable itself if made of tiny reflective glass or plastic fibers. light bounces off the reflective surface to transmit down the cable.
Super-fast broadband
Can also be used for networking in businesses but this is rare due to its cost
Disadvantages
Very expensive, extra equipment required to run the network as it much more costly
Advantages
Excellent data transfer range, over 100km possible
Excellent security, not susceptible to interference or generating noise and cannot be tapped to intercept data
Very fast data transfer, 100Gps
