Expert Solution

First i am explain the three basic function of sytsem

at last with a simple example i am explain how the basic function works on a computer system

three basic functions of system

Input

  • Data and Instructions which we give to the computer are known as input
  • eg: keyboard, mouse, etc

Process

  • Work done on data according to the given instruction is known as processing
  • eg: CPU (Central Processing Unit) is the brain of the computer. all data and instruction which are given to the computer is processed within the CPU
  • It stores all the data, intermediate results, and instructions as given by the programmer in the form of codes.

Output

  • processed data is knows as output .Output is the function that allows a computer to display information, from the system, for the user.
  • eg: Monitor,Printer,Speaker etc..

How Basic Function Works On a System with a simple Example

  • eg: with a simple example below explain how the basic function of compter system works
  • Suppose when we add two numbers 4 and 5 on a computer system
  • 4+5

our input will be two numbers 4 and 5

Processing is the addition (+) of two numbers

Finally our output is 9 addition of two numbers

Consider 2-bit input functions that has either constant output (0 or 1) or balanced output (the number of {0,1} outputs are equal to each other). First a class is selected with1/2 probability and then one of the functions that belong to the chosen class is selected uniform randomly. We would like to guess the class of the function with minimum function evaluations. • What is the average number of guesses before we identify the chosen class using classical bits? •...
