Why an approximate value required to turn on a npn silicon type transistor?

The base of a transistor is basically a diode wich follows an exponential curve at very low level it display an almost infinite inpedance but at hi lelvel any additional diode current will not increase its voltage drop therefore a nominal value is assigned of .6v to .7v

What is the major advantage of shielded twisted-pair over unshielded twisted pair cable?

UTP-Unshielded Twisted Pair. Normally UTP contains 8 wires or 4 pair. 100 meter maximum length. 4-100 Mbps speed.STP-Shielded twisted pair. 100 meter maximum length. 16-155 Mbps speed. Lower electrical interference than UTP
