Unshielded twisted pair (UTP)

• telephone systems, both indoors and out
• computer networking.
• UTP cables are often called ethernet cables after Ethernet, (LAN)
• The most common data networking standard that utilizes UTP cables.

uses of Coaxial cables:

• home video equipment,
• In ham radio setups, and in measurement electronics.
• Common for implementing computer networks, in particular Ethernet,but twisted pair cables have replaced them in most applications except in the growing consumer cable modem market for broadband Internet access.
• Long distance coaxial cable is used to connect radio networks and television networks,
• Micro coaxial cables are used in a range of consumer devices, military equipment, and also in ultra-sound scanning equipment.

The most common impedances that are widely used are 50 or 52 ohms, and 75 ohms, although other impedances are available for specific applications.

• The 50 / 52 ohm cables are widely used for industrial and commercial two-way radio frequency applications (including radio, and telecommunications), although 75 ohms is commonly used for broadcast television and radio
