Ethernet cables are grouped by category, which determines the maximum speed they support:
Cat 5e: supports speeds up to 100 Mbps. Suitable for basic broadband connections.
Cat 6: supports speeds up to 1 Gbps. Recommended for most business setups.
Cat 6a / Cat 7: supports speeds up to 10 Gbps. Used for high-performance or future-proofed networks.
Cable types
Unshielded (UTP): the most common type, suitable for standard office and home networking.
Shielded (STP): includes additional shielding to reduce electrical interference. Used in environments with heavy equipment or long cable runs.
