... Choosing the resistors R1 and R2 such that RB << (f +1)RE is equivalent to making the current through R1 and R2 large enough that the BJT's base current can be neglected in comparison. The base voltage is thus determined only by VCC and the R1 and R2 voltage divider. The DC Operating point of this ...

History of the transistor
A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. The vacuum-tube triode, also called a (thermionic) valve, was the transistor's precursor, introduced in 1907.
