Types of Internet Cables

Ethernet cable

An Ethernet cable connects a computer, a laptop, or even a game console to a router or modem. It sends and receives broadband signals so that computers can communicate with each other and transfer data from one to another.1 It’s one of the most common tools that computers use to transfer data across the Internet. A special kind of Ethernet cable, however, called a “cross-over cable,” connects two computers to each other directly and thus doesn’t need a modem or router to transfer data.

Coaxial cable

A Coaxial Cable is a cable most often used to connect a cable box or modem to the incoming connection port in the wall. They can be analog, which typically have a small pin in the center of the connection and screw on, or digital, which press in and stay connected due to pressure.

Coaxial cables are made up of several parts:2

  • A conductor, which is the center wiring that actually transmits the data
  • Two to three layers of shielding to protect the signal from electrical interference
  • And a layer called the jacket which physically protects the cable

HDMI cable

HDMI stands for “High-Definition Multimedia Interface,” and an HDMI cable is used for transmitting audio and video data in a single cable. HDMI cables are used to connect devices including:

  • HDTV’s
  • DVD players
  • Blu-Ray players
  • Laptops
  • Video game systems

HDMI cables provide a digital connection, which is less prone to signal noise and interference than analog cables. When an HDMI cable is used, the audio and video is transferred digitally. This eliminates the analog to digital conversion, providing a clearer picture and quality sound.3
