What is a major advantage of UTP?It is inexpensive. It limits the number of hosts on a network. It is an inexpensive way to interconnect remote locations. UTP stands for Unshielded Twisted Pair. Unshielded means just as its name suggests. It offers absolutely NO protection against EMI, or electromagnetic interference.
Shielded Twisted Pair (STP) is twisted pair cabling includes a shield.This type of cabling is not commonly seen in modern LAN networks deployments till 2011 however some newer very high speed Ethernet technologies may require a cable that has a shield.
At the Speed of Twisted Thought... was created in 1980-08.
From a networking perspective the two main types of twisted pair cable that have been used extensively; particularly with Ethernet, are Shielded Twisted Pair (STP) and Unshielded Twisted Pair (UTP). The biggest difference between the two is the presence or absence of a shielding layer but all types use various twist periods to reduce the effect of electromagnetic interference (EMI) or noise and cross-talk interference.
Twisted pair wire is placed inside a thin metallic shielding, similar to aluminum foil, and is then enclosed in an outer plastic casing. The shielding provides further electrical isolation of the signal-carrying pair of wires. Shielded twisted pair wires are less susceptible to electrical interference caused by nearby equipment or wires and, in turn, are less likely to cause interference themselves. Because it is electrically "cleaner," shielded twisted pair wire can carry data at a faster speed than unshielded twisted pair wire can. The disadvantage of shielded twisted pair wire is that it is physically larger and more expensive than twisted pair wire, and it is more difficult to connect to a terminating block.
Yes, but only on twisted thicket island
Speed does not travel. The word speed is a general term for velocity.
The speed of light is approximately 3x10^8ms (exactly 299,792,458 m/s), but electric signals don't travel that fast in conductors. They travel anywhere from 40% up to 95% of that speed, depending on properties of the cable (the dielectric constant of the material surrounding the copper is a big factor).Twisted pair copper cabling used in telephone wiring tends to be on the lower end, somewhere between 40% to 70%. So a good estimate is somewhere between 120,000,000 m/s to 210,000,000 m/s.(The drift speed of electrons in a wire is much slower, on the order of millimeters per second. Electric signals travel through conductors as an electromagnetic wave.)

That depends on the speed. If you know at what speed you will travel, divide the distance by the speed.That depends on the speed.

It doesn't work that way. For a start, speed doesn't travel. Rather, an object travels at a certain speed.
