2. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   The best coaxial cable impedances were experimentally determined at Bell Laboratories in 1929 to be 77 Ω for low-attenuation, 60 Ω for high-voltage, and 30 Ω for high-power. For a coaxial cable with air dielectric and a shield of a given inner diameter, the attenuation is minimized by choosing the diameter of the inner conductor to give a ...

3. RG-59 - Wikipedia

   en.wikipedia.org/wiki/RG-59

   RG-59 coaxial cable is commonly packed with consumer equipment, such as VCRs or digital cable/satellite receivers. Manufacturers tend to include only RG-59 cables because it costs less than RG-6 does. However, given the short lengths provided (usually 4–6 ft or 1.2–1.8 m), this is generally sufficient for its typical use.

4. Networking cable - Wikipedia

   en.wikipedia.org/wiki/Networking_cable

   Different types of network cables, such as coaxial cable, optical fiber cable, and twisted pair cables, are used depending on the network's topology, protocol, and size. The devices can be separated by a few meters (e.g. via Ethernet) or nearly unlimited distances (e.g. via the interconnections of the Internet).

5. RG-6 - Wikipedia

   en.wikipedia.org/wiki/RG-6

   RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. An RG-6/U coaxial cable has a characteristic impedance of 75 ohms. The term, RG-6, is generic and is applied to a wide variety of cable designs, which differ from one another in shielding characteristics, center conductor composition ...

6. 10BASE2 - Wikipedia

   en.wikipedia.org/wiki/10BASE2

   10BASE2 (also known as cheapernet, [1] thin Ethernet, thinnet, and thinwire) is a variant of Ethernet that uses thin coaxial cable terminated with BNC connectors to build a local area network. During the mid to late 1980s, this was the dominant 10 Mbit/s Ethernet standard.

7. Broadband - Wikipedia

   en.wikipedia.org/wiki/Broadband

   In telecommunications, broadband or high speed is the wide-bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast Internet access. The transmission medium can be coaxial cable, optical fiber, wireless Internet , twisted pair cable, or satellite.
