Unit 1: Page 15: Wired Connection Methods Flashcards
What are wired connection methods?
Wired methods of connecting devices are any method that uses physical cables to connect between devices, systems or components.
Name the 3 Wired System Connection Methods.
> Cat5
Coaxial
Fibre Optic
What are the uses of Cat5?
Telephone communications and ethernet networks.
What are the advantages of Cat5?
> Versatile and widely available
Cheap compared to other networking options
What are the limitations of Cat5?
> Only useful over shorter distances
More susceptible to interference than other wired techniques such as fibre.
What are the uses of Coaxial?
All types of data communication, commonly used in television cabling.
What are the advantages of Coaxial?
> Less susceptible to interference than UTP/STP so works over longer distances.
Cheap, though not as cheap as UTP/STP
What are the limitations of Coaxial?
> Thickness of cable makes it difficult to work with
Limited bandwidth
What are the uses of Fibre Optic?
Telephones and internet cables, cable television and computer networking.
What are the advantages of fibre optic?
> Improved security as the cable cannot be tapped.
Can be used over long distance
High data transfer rate
What are the limitations of fibre optic?
> Very expensive
Specialist skills needed to install.
What are the 3 Wired Device Connections?
> VGA
HDMI
USB/FireWire
What are the uses of VGA?
Analogue connection of video display equipment, such as projectors, CRTs or LCDs.
What are the advantages of VGA?
> Universally used in high - resolution display equipment
Low-cost cabling
What are the limitations of VGA?
> Cumbersome cabling
Signal affected over distance (noise)
No DRM (digital rights management)
