Transistor

Refer Earlier Post 

 

Transistor is the Component which is based on the Semiconductor.

And which does the actual control of current flow within electronic devices.

 

Previously it was Vacuum tubes which was used for same purpose.

But is was not pragmatic solution due to huge size and overheating.

 

Now There is no electronic device without transistors.

 It all started noticeably with Radio .Sony mass produced Radio by replacing Vacuum Tubes with Transistors.

Thats why infact Radios were earlier referred simply as Transistors. 

 

In computers,They are used for storing bits (binary digit 0 and 1)  .

Since transistor control the current flow,

When there is No current Flow-->Store 0 digit

When there is Current Flow-->Store 1 digit

When there are more & more transistors , this will increase the computation power/parallel processing.

Hence now billions of transistors within a single computer.(ofcourse within Integrated Circuits)

 

 

Biggest invention

Semiconductor

Semiconductor is one of the biggest invention of manhood.

Why?

Conductor->Fully passes the current

Insulator-->Fully rejects the current 

Semiconductor-->It is somewhere inbetween, partially passes the current.

Electronic devices apparently powered by current and they could not have Conductors inside its components, which will result only in damage of its intrinsic components.

Current Flow must be controlled within the components of Electronic devices.

Semiconductor is the base material to control the Current Flow! 


Having said that, a component ,built with Semiconductor as a base material, does the actual Controlling of Current Flow.

Do you know? which is that component?
