The role of network cables in daily life

The role of network cables in daily life
Network cables (twisted pair cables) are used to transmit network signals. Compared to WiFi, they have stable signals, low latency, and are less susceptible to interference from walls and electrical appliances. They are the carriers of wired networks.

Daily use
1. Home broadband internet access
The optical modem connects to the router via an Ethernet cable, and the router then connects to computers, NAS devices, and televisions via Ethernet cables to achieve a stable network. WiFi is merely a wireless extension; home broadband is mainly transmitted via Ethernet cables.
2. Desktop computer internet access
Many desktop computers do not have wireless network cards; simply plugging in an Ethernet cable enables connection; when playing games or downloading large files, wired connection has lower latency and fewer packet losses compared to WiFi.
3. Television / Box Internet Connection
For binge-watching shows and watching 4K videos, Ethernet cables are more smooth than WiFi, reducing lag and buffering, especially when the living room is far from the router.
4. Surveillance Cameras
POE Ethernet cables can simultaneously transmit network signals and provide power, making it possible to use a single Ethernet cable for home and store surveillance, eliminating the need for separate power cables.
5. NAS Private Cloud, Storage Server
Home network drives, file storage, Ethernet cables ensure high-speed reading and writing, and copying photos and videos is stable.
6. Game Consoles (PS5/Xbox)
For online games, Ethernet cables are preferred to reduce latency and minimize disconnections, enhancing the gaming experience.
7. Office Scene
Company computers, printers, switches are networked via Ethernet cables, sharing files internally and printing; computers in meeting rooms have wired screen projection for internet access.
8. Other Devices

Some smart devices: network radio, IP phone, industrial control equipment, network wiring in weak current boxes.
