The transistor was originally used in computers to replace the vacuum tube.
The function of the vacuum tubes was to regulate the flow of energy throughout the computer in order to answer a function.
Transistors are semiconductors that are most commonly embedded in Central Processing Unit (CPU) chips. These "electric flow regulators" act as microswitches to help the computer "think."
Yes, today's computers use transistors and microprocessors. Smaller transistors subset the amount of RAM that is local to the CPU at any given moment.
Billions.
Early transistors were much slower and far more expensive than vacuum tubes. Also computers built before 1948 there were no transistors to use at all.
No.
no, second generation. third generation computers used ICs.
discrete transistors
Radios, Televisions & Computers.
Anywhere from none to many billions, depending on the computer.vacuum tube computers had no transistorstransistorized computers had a few thousand to a few hundred thousand transistorsintegrated circuit computers had a few tens of thousands to a few million transistorsmicroprocessor computers have had a few thousand to many billions of transistors
Second generation computers are often called transistorized computers. The transistorized computers are more advanced computers than the first generation of computers.
Transistors have two basic functions: # an electrically controlled electric switch # an electrically controlled "proportional valve" which can alter currents and voltages, or can amplify electric signals. Transistors can also be configured as Oscillators which provide an AC signal with constant frequency. Either an amplifier circuit or a switching circuit can be wired as an oscillator. Transistors can be used to form logic gates: And, Or, and Invert. Computers are made from logic gates, so computers can be made entirely from transistors. Transistors are in use in virtually all electronic devices. PC processors are composed of millions of tiny transistors. A transistor radio may have had only 6-10 transistors to enable operation. A late model car may have 10 to 15 computers comprised of thousands of transistors to perform all manner of operations in the vehicle.
A modern micro processor has atleast 100 million transistors.
Physical is something tangible like cables, cards, the actual computers... It is more in electronics domain then computers. Ya know... transistors, diodes, pcb...
