Unshielded Twisted Pair
Unshielded twisted pair (UTP) cabling is the most common cable used in computer networking. It is a variant of twisted pair cabling. UTP cables are often called ethernet cables after Ethernet, the most common data networking standard that utilizes UTP cables, although not the most reliable. Wikipedia does not have an article with this exact name. ... 25 Pair Color Code Chart 10BASE-T UTP Cable Twisted pair cabling is a common form of wiring in which two conductors are wound around each other for the purposes of cancelling out electromagnetic interference known as crosstalk. ...

In contrast to FTP and STP cabling, UTP cable is not surrounded by any shielding. It is the primary wire type for telephone usage and is very common for computer networking, especially as patch cables or temporary network connections due to the high flexibility of the cables. Foiled twisted pair cabling is used in computer networking. ... A diagram of an STP cable Shielded Twisted Pair, sometimes abbreviated STP, is a kind of copper wiring where a pair of wires are twisted around each other and covered in an insulating tube. ...

A patch cable or patch cord (sometimes patchcord or patchcable) is an electrical cable, used to connect (patch-in) one electronic device to another for signal routing. ...
Advantages
It is a thin, flexible cable that is easy to string between walls.
Most modern buildings come with CAT 5 UTP already wired into the wall outlets or at least run between the floors.
Because UTP is small, it does not quickly fill up wiring ducts.
UTP costs less per foot than any other type of LAN cable.
Disadvantages
It is more susceptible to interference than most other types of cabling. The pair twisting does help, but it doesn't make the cable impervious to electrical noise.
Its unrepeated length limit is 100 metres.

Cat 1: Currently unrecognized by TIA/EIA. Previously used for POTS telephone communications, ISDN and doorbell wiring.
Cat 2: Currently unrecognized by TIA/EIA. Previously was frequently used on 4 Mbit/s token ring networks.
Cat 3: Currently defined in TIA/EIA-568-B, used for data networks using frequencies up to 16 MHz. Historically popular for 10 Mbit/s Ethernet networks.
Cat 4: Currently unrecognized by TIA/EIA. Provided performance of up to 20 MHz, and was frequently used on 16 Mbit/s token ring networks.
Cat 5: Currently unrecognized by TIA/EIA. Provided performance of up to 100 MHz, and was frequently used on 100 Mbit/s ethernet networks. May be unsuitable for 1000BASE-T gigabit ethernet.
Cat 5e: Currently defined in TIA/EIA-568-B. Provides performance of up to 100 MHz, and is frequently used for both 100 Mbit/s and gigabit ethernet networks.
Cat 6: Currently defined in TIA/EIA-568-B. It provides performance of up to 250 MHz, more than double category 5 and 5e.
Cat 6a: Future specification for 10 Gbit/s applications.
Cat 7: An informal name applied to ISO/IEC 11801 Class F cabling. This standard specifies four individually-shielded pairs (STP) inside an overall shield. Designed for transmission at frequencies up to 600 MHz.
Unshieldedtwistedpair is the most common kind of copper telephone wiring.
Twistedpair is now frequently installed with two pairs to the home, with the extra pair making it possible for you to add another line (perhaps for modem use) when you need it.
Although twistedpair is often associated with home use, a higher grade of twistedpair is often used for horizontal wiring in LAN installations because it is less expensive than coaxial cable.
