If the integrated circuit in some kind of device has 5,000 transistors on it, then
before integrated circuits were available, the same function might have been
performed by 100 individual transistors. And before transistors were available, the
same function might have been performed by 30 vacuum tubes, a fan and air system
to keep them cool, and a large power system to operate the tubes and the cooler.
A fridge may or may not have a few transistors in it, these are electrical components that would probably be part of the control circuitry. Transistors used to be very common components of most electrical appliances. The cooling process of the fridge has nothing to do with transistors and is handled by a compressor and a heat exchange pump

You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
I am not to sure about Static Ram but in CMOS RAM, 1GB of RAM would contain about 137438953472 transistors because 1 bit of CMOS RAM contains 16 Transistors, 8 bits in a byte and 1073741824 bytes in a gigabyte. I am 100% sure about this and these are just estimations. Static RAM uses about 6 times as many transistors as dynamic RAM for the same amount of storage. Dynamic RAM uses 1 or 2 transistors per bit in typical implementations. Add to this transistors for address decode, bus interface, etc.
it acts as a direct switch by usingg a battery. it is also used in transistors
Tubes, magnetic logic, and transistors.
There were vacuum tubes before transistors
Silicon and germanium are the elements used in transistors
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.
Power transistors are transistors that are used in high-power amplifiers and power supplies.
Transistors are used in any electrical somponent including amplifiers, remote controls etc.
Silicon and germanium are the elements used in transistors
Silicon and germanium are the elements used in transistors
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
Transistors are used for switching devices! What gave you the idea they aren't?
Silicon is the substance in sand that is used in making transistors. Silicon is used as the raw material for producing the silicon wafers, which are then processed to create the transistors.
