Wired Vs Wireless Connection 9 Flashcards
What are examples of wireless connections
CAT5
Coaxial
Fibre Optic
VGA
HDMI
USB/ Firewire
CAT5 uses
Telephone communication and Ethernet networks
CAT5 advantages
Versatile and widely available
Cheap compared to other networking options
CAT5 disadvantages
Only useful over a short distance
More susceptible to interference from other wired techniques such as fibre
Coaxial uses
All types of data communication but most commonly used in television cabling
Coaxial advantages
Less susceptible to interference than UTP/ STP so works over longer distances
Cheap, though not as cheat as UTP/ STP
Coaxial disadvantages
Thickness of cable makes it very difficult to work with
Limited bandwidth
Fibre optic uses
Telephone and internet cables, cable television and computer networking
Fibre optic advantages
Improved security as the cable cannot be tapped or hacked into
Can be used over long distances
High data transfer rate
Fibre optic disadvantages
Very expensive
Specialist skills needed to install
VGA uses
Analogue connection of video display equipment such as projectors
VGA advantages
Universally used on high resolution equipment
Low cost cabling
VGA disadvantages
Cumber stone cabling
Signal affected over distance
No DRM (Digital rights management) Amazon and Netflix use to block wire from carrying data
HDMI uses
Digital connection of both video and sound from devices to display equipment
HDMI advantages
Capable of 8k and beyond resolution
Used in computing and entertainment
HDMI disadvantages
Limited length
Cabling and technology is more expensive than analogue equivalent such as VGA
USB/ FireWire uses
Connecting equipment and peripherals such as printers, scanners, input devices, cameras
USB/ FireWire advantages
High speed capability
Backwards compatibility
Can connect multiple devices
USB/ FireWire disadvantages
Limited distance
Limited power supply
Wireless connections examples
