Serial communication means transfer data bit by bit serially at a time, where as in parallel communication, the number of bits that can be transferred at a time depends upon the number of data lines available for communication.Read More..
8051 microcontrollers have two timers/counters which work on the clock frequency. Timer/counter can be used for time delay generation, counting external events etc.Read More..
An interrupt is an event that occurs randomly in the flow of continuity. It is just like a call you have when you are busy with some work and depending upon call priority you decide whether to attend or neglect it. Read More..
