i am new to electronic, so i donot know some components in electronic circuitswhenever i open any electronic device i find a black plastic like spot where all the cicuit line are connected whats the use my friend told it protects someting ,but what ?
The plastic spot has an internal computational function- in essence it is a very simple computer chip, and the plastic is the same as that covering and protecting those chips. The blob-chip contains anywhere from a few dozen to a few hundred logic gates; easily enough to perform any calculatory and switching functions.
