The UTP (Unshielded twisted pair) cable is preferred; it's far less expensive to install in large amounts.
Coaxial cable, STP cable, UTP cable
STP is more reliable due to shielding.
UTP is cheaper to install than STP or coaxial cable; therefore, it is a popular network choice
UTP cable, BNC connector, STP cable
STP is more reliable because it can withstand more noise abuse than UTP and therefore provide a more reliable transmission.
UTP Is unshielded and STP is shielded UTP generally being bulkier and more expensive.
Cat 6 UTP
Cat 6 UTP
Cat 6 UTP
Type 1A STP or Cat 5 UTP.
The best Ethernet cable is CAT-6 (UTP), if you have enough money you can get STP for better performance and stability.
UTP is unshielded. Cheaper. STP is shielded.. more expensive.
