Transistors are the fundamental building blocks of a computer, just as cells are the buildin blocks of any living organism. It is rare to find any individual transistors in a modern computer but every integrated circuit contains vast number of them. For example, every memory location will have a pair of trasistors, so there are 16 of them for each byte, so 16 million of them for each megabyte of memory. The central processor which carries out all the calculations and other processes also contains millions of transistors. As integrated circuits are developed, the size of each transistor gets smaller, so more can be packed into single chips but they are still doing the same job as the individual transistors that were used to build the very first solid state computers. To learn more about the way transistors operate in a computer, it is worth looking the way they are used to make simple logic gates. The basic gates such as OR, NOR, AND, NAND and various latches are used to create the powerful computers we take for granted today. A study of these gates will offer some insight into the way computers store, move and manipulate data using transistor technology.

Base resistance (Rb) is the resistance seen by the base terminal of a transistor when analyzing its behavior in a circuit. It is a parameter used to model the input impedance of the transistor and is crucial in determining the biasing and signal amplification characteristics of the transistor circuit.
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
a transistor circuit for driving the coil of a magnetic relay.
A digital circuit composed of bipolar junction transistors (BJTs). Widely used in all variety of electronic applications, especially prior to CMOS circuits becoming popular, TTL superseded the earlier RTL (resistor-transistor) and DTL (diode-transistor) logic designs, which used more power. In TTL, transistors are used to both isolate inputs and perform the logic switching. A "TTL" designation on a circuit input or output indicates a digital circuit rather than analog.Read more: transistor-transistor-logic-electronics
Transistor are DC output, Triac are AC output.
A load line is used in graphic analysis of circuits, having both linear and non-linear parts, representing the constraint the other parts of the circuit put on the non-linear transistor. It represents the response of the linear circuit connected to the transistor. The DC load line describes the DC operation of a transistor graphically.
This mechanism is how a transistor works.
