Multiple Choice

Which four LAN cable types are commonly used as per the material?

Understanding LAN cabling categories helps you pick cables that match the needed speed and distance for a network. The four commonly used copper Ethernet cables are Cat5, Cat5e, Cat6, and Cat6a. They’re all twisted-pair copper cables designed for Ethernet with RJ-45 connectors, and they’ve become the standard building blocks for most local networks. Cat5 is older and mostly phased out for new installs, but it set the baseline for Ethernet. Cat5e improves on Cat5 by better handling interference, enabling reliable 1 Gbps networks over typical distances. Cat6 ups performance further, supporting higher frequencies and offering improved insulation and less crosstalk, which helps maintain higher speeds over longer runs (including 10 Gbps for shorter distances). Cat6a extends even further, maintaining 10 Gbps at full 100-meter lengths with even better shielding. Together, these four cover the common, practical range of LAN deployments you’re likely to encounter, from standard office networks to higher-speed needs, without jumping to newer or less widely deployed standards. Other listed items aren’t typical LAN cables, and while newer categories exist, they’re not as universally used in everyday setups.
