From an audio amplifier standpoint, transistors were primarily low-voltage, high current devices. Since loudspeakers were typically low-impedance, the transistorized circuit didn't require a transformer to help match the impedance; i.e. they were better matched. However, when a transistor "saturated" it "clips" abruptly, causing harmonics at the output. Vacuum tubes tended to "soft clip' which reduced the undesirable harmonics.
From another standpoint, transistors were smaller in size, didn't require high voltage power supplies, and dissipated less heat (i.e. more efficient).
a semiconductor device on changing temperature can be used as a conductor as well as an insulator.this is the main advantage of a semiconductor device.it is also light weight,small,cheap and finds many applications in modern devices like computers,electrical appliances.
Apple Macs don't use valves (computers haven't used valves since around 1955). However, transistors are very much smaller than valves (by several orders of magnitude), are much more reliable, are cheaper to mass produce and offer much greater efficiency.
because of high output drive,easy to manufacture and takes less space and also low power consumption...
it converts it to a diode. sometimes this is done for matching the characteristics of diodes and transistors in the circuit. standard diodes might not have similar enough curves to the transistors for the circuit to operate correctly.
It is used as a compressor. It has the same advantages over a piston compressor as a gas turbine engine has over a piston engine. i.e. no valves, much lower part count and much greater efficiency.
Thyristors are preferred in applications that require the characteristics on a thyristor. Thyristors are quite different to transistors, when they turn on, they stay turned on untill the power source is removed. Transistors conduct as controlled by the emitter current.

because the amplifying function are performed by transistors (contrast with RTL and DTL).
Yes they are. The invention of the transistor signalled the end of large, bulky valves in circuits. Modern transistors are so small - that thousands can be housed on one microchip.
discrete transistors
Because - when Colossus was built (in 1943), microchips had yet to be invented ! Microchips replaced valves and transistors in newer computers.

I will assume you mean "transistors". Compared to their predecessors (vacuum tubes), transistors:* Are faster * Use less current * Use less space Note that all of these advantages get even more pronounced in the case of integrated circuits (which also contain transistors).
Silicon chips replaced individual transistors and before that vacuum tubes (valves).

ball valves offer numerous advantages over other types of valves, including quick and easy operation, tight sealing, low torque requirements, durability, versatility, and minimal pressure drop. D Chel Valves are the leading Ball Valves Manufacturers in India.

There are no valves in a modern computer. If by valves you mean vacuum tubes, the equivalent is a transistor. Modern CPUs have many transistors/gates on their dies. The SandyBridge i7, a near-top end general purpose computer COU can have 2.2 billon transistor elements on the CPU die. Of course there are many more transistors incorporated in the logic chips, controllers and video cards in a computer as well.
