Topic 15 - Wired Connection Methods Flashcards
What are wired methods of connecting devices?
They are any methods that use physical cables to connect between devices, systems, or components
What do different types of connections rely on?
Different types of connection rely on widely differing connectors, depending on what the signal of data
What is the use of Cat5? (Wired System Connection Methods)
Use = Telephone communications and ethernet network
2 Advantages of Cat5
Versatile and widely available
Cheap compared to other networking options
2 Limitations of Cat5
Only useful over shorter distances
More susception to interference than other wired techniques such as fibre
What is the use of Coaxial? (Wired System Connection Methods)
Use = All types of data communication, commonly used in television and computer networking
2 Advantages of Coaxial
Less susceptible to interference than UTP/STP so works over longer distances
Cheap, though not as cheap as UTP/STP
2 Limitations of Coaxial
The thickness of the cable makes it difficult to work with
Limited bandwidth
What is the use of Fibre optic? (Wired System Connection Methods)
Uses = Telephone and internet cables, cable television, and computer networking
3 Advantages of Fibre optic
Improved security as the cable cannot be tapped
Can be used over long distance
High data transfer rate
2 Limitations of Fibre optic
Very expensive
Specialist skills needed to install
What is the use of VGA? (Wired device Connection)
Use = Analogue connection of video display equipment, such as projectors, CRTs, or LCDs
2 Advantages of VGA
Universally used on high-resolutiondisplay equipment
Low-cost cabling
3 Limitations of VGA
Cumbersome cabling
Signal affected over distance (noise)
No DRM (digital rights management)
What is the use of HDMI? (Wired device Connection)
Use = Digital connection of both video and sound from devices to display equipment
Advantages of HDMI
Capable of 8k (and beyond) resolution
Used on computing and entertainment
2 Limitations of HDMI
Limited length
Cabling and technology are more expensive than analogue equivalents such as VGA
What is the use of USB/FireWire? (Wired device Connection)
Use = Connecting equipment and peripherals, such as printers, scanners , input devices, cameras
3 Advantages of USB/FireWire
High speed capabilility
Backward compatibility
Can connect multiple devices
2 Limitations of USB/FireWire
Limited distance
Limited power supply
