Data cabling, also known as structured cabling, refers to the physical infrastructure used to transmit data within a network. It includes cables, connectors, and related hardware. It is crucial for creating a reliable and efficient network by providing a standardised and organised way to connect devices such as computers, VoIP telephones, WiFi points and other networked equipment.

Common types of data cables used in networking include:
Ethernet Cables (Cat5e, Cat6, Cat6a, Cat7): Used for wired Ethernet networks.
Fiber Optic Cables: Transmit data using light signals, offering high bandwidth and long-distance capabilities.

These are different categories of Ethernet cables with varying performance characteristics:
Cat5e (Category 5e): Supports speeds up to 1 Gbps and is suitable for most common networking applications.
Cat6 (Category 6): Provides higher performance with support for speeds up to 10 Gbps, often used in environments with greater data transfer requirements.
Cat6a (Category 6a): Offers enhanced performance over Cat6, supporting speeds up to 10 Gbps over longer distances and with improved crosstalk protection.

A WiFi connection is great for flexibility and if you are constantly on the move. However, a hardwired connection will allow you to get the most out of your available bandwidth. A good WiFi connection can be sporadic and have ‘black spots’. Whereas a hardwired connection will give you the most reliable service.
