Cat5 use case + Cons and pros
use:
Telephone communications
and Ethernet networks.
Advantages:
1. Versatile and widely
available.
2. high-transfer speeds at a low cost.
3. can be used in a variety of applications, from networking to telephone wiring.
Limitation:
1. Only useful over shorter
distances.
2. IP More susceptible.
Coaxial use case + Cons and pros
Use case:
All types of data
communication, commonly
used in television cabling
Advantages:
1. It is easy to install coaxial cables
2. Works over longer distances.
3. Cheap.
Limitation:
1. The thickness of the cable makes it difficult to work with.
2. Limited bandwidth.
Fibre Optic use case + Cons and pros
Use case:
Telephone and internet
cables, cable television and
computer networking.
Advantages:
1. improve security as the cable cannot be tapped.
2. Can be used over long distances.
3. High data transfer rate
Limitation:
1. Very expensive.
2. Specialist skills are needed to install.
Wired device connections (VGA)
use:
Analogue connection of video display equipment, such as projectors, CRTs or LCDs.
Advantages of VGA:
1. Universally used on high-resolution display equipment.
2. Low-cost cabling
Disadvantages’ of VGA:
1. Cumbersome cabling.
2. Signal affected over distance (noise).
3. No DRM (digital rights management).
Wired device connections (HDMI)
Use case of HDMI:
Digital connection of both video and sound
from devices to display equipment.
Advantages of HDMI:
1. Capable of 8k (and beyond) resolution.
2. Used in computing and entertainment.
Disadvantages of HDMI:
1. Limited length.
2. Cabling and technology are more expensive than analog equivalents such as VGA.
Wired device connections (USB/
FireWire)
Use CASE:
Connecting equipment and
peripherals, such as printers,
scanners, input devices, cameras.
Advantages:
1. High-speed capability.
2. Backward compatibility.
3. Can connect multiple
devices.
Disadvantages:
1. Limited distance.
2. Limited power supply
Wireless connection methods
Wireless connection methods connect using the electromagnetic spectrum. This may be traditional radio waves or even light waves.

broadband)
Use Case:
Provides connectivity to
remote areas, often rural.
Advantages:
1. Wide coverage.
2. High speed.
Disadvantages:
1. High latency.
2. Subject to weather conditions.
Wireless system connection (Microwave/Laser)
Use case:
Allows point-to-point LAN
connections between
locations.
Advantages:
1. High speed.
2. No ongoing costs.
Disadvantages:
1. Affected by poor weather.
2. High initial cost.
