suppose you’re trying to interface a matrix keyboard connected to a seven segment display, to display the key that you’re pressing onto it.   b) Explain the necessary steps that take place while registering a particular input from the matrix keyboard? (You may or may not use assembly code instructions to support your answer, only the proper explanation should suffice) Suppose you want to display your cgpa using three seven segment displays. c) How would you interface the seven segment displays with IC 82c55? (Use your cgpa as an example to differentiate your answers with the others

Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.
