What is the primary use of CAT 5e cable?

1. Video transmission

2. Networking

3. Audio transmission

4. Television connection

The correct answer is: Networking

The primary use of CAT 5e cable is networking. This type of cable is designed to support Ethernet and other networking standards, facilitating high-speed data transmission in local area networks (LANs). CAT 5e, which stands for Category 5 enhanced, can handle data rates up to 1 Gbps over distances up to 100 meters, making it widely used for connecting computers, switches, and routers in both residential and commercial settings. The specifications of CAT 5e enable it to reduce crosstalk and interference, which is crucial for maintaining signal integrity within a network. This makes it an ideal choice for applications that require reliable and fast data communication, such as internet connectivity, voice over IP (VoIP), and other networked uses. While other options like video transmission, audio transmission, and television connection may utilize different types of cabling that are better suited for their specific requirements, CAT 5e remains primarily associated with networking tasks, reinforcing its role as a foundational component in modern communication infrastructures.
