The most popular cabling these days is Ethernet.
Twisted-pair cable
Yes, UTP is the most popular cabling standard used in majority of networks all over the world.
Which two places are most appropriate to use UTP cabling?

Rj-45 is the most common type of cabling. RJ-45 refers to the terminator (connector) on the end of the cable, and the jack it plugs into--more specifically RJ-45M and RJ-45F, respectively. The associated cabling will be CAT(category)-5 or CAT-5e(enhanced), which are in the class of Unshielded Twisted Pair. A star network is typified by the hub or switch, with a cable running from it to every device on the network. Other cabling might be used, but CAT-5 is far and away most common.
The most common topology in use today is the star topology, primarily due to its scalability and ease of management. This topology often utilizes Ethernet technology, particularly with twisted-pair cabling, which is prevalent in local area networks (LANs). The star topology allows for easy addition and removal of devices without disrupting the network, making it ideal for modern networking needs. Additionally, advancements in wireless technology have also popularized star topology in Wi-Fi networks.
Local Area Network A data network that does not include routing to remote locations. The most common protocol for wired LAN is currently Ethernet. The most common cabling for wired LAN is currently UTP (unshielded twisted pair) copper.

When installing Ethernet cabling in areas with high electrical interference, a tech is most likely to use shielded twisted pair (STP) cabling. STP includes shielding that protects the data signals from electromagnetic interference (EMI), ensuring better performance and reliability. Additionally, using Category 6 (Cat 6) or higher cabling can enhance resistance to interference while supporting higher data rates.
Ethernet cabling is cheap and fast enough for most purposes.
