explian to a 5 years old child ,,,"what does Intergraded Circuit (IC) do in a circuit ??

Answer 1

An IC is just a complicated circuit all glued together in one black block.

It has a number of pins or legs on the outside that provide the inputs an outputs for the tiny components sealed within the main body...

The circuit itself could be anything from a simple counter... to a brand new CPU chip for a supercomputer... It all depends on the imagination of the designer.

Answer 2

IC's have many different functions depending on what circuit they are in . Consider a cellphone vs a laptop etc.

What is common is that IC's are very small circuits. At one time we built TV's and radios using very large Vacuum Tubes.
These TV's and Radios were very large. (about the size of a kitchen cabinet)

The vacuum tubes were replaced by smaller devices called transistors. The smaller components allowed making smaller devices. So a Radio could be built the size of a toaster.


And finally the transistors were shrunk into even smaller sized and many were placed onto a small Integrated Circuit (IC). Tis allows building the very small devices you have in use today.

Answer 3

Just try to re-phrase what Lowlevel said in terms a 5 year old can understand. Good luck! Very exciting that he's interested.

Answer 4

its a smaller packing of big circuits, connections and wires to make their handling easier.
