Consider the following program main() { fork() ; fork() ; fork( ) ; } How many new processes will be created ?

Consider the following program main() { fork() ; fork() ; fork( ) ; } How many new processes will be created ? Correct Answer 7

Concept:

Fork system call is used to create a new process also called a child process or new process.

Formula:

With n fork system calls, number of new (child) processes created is 2n – 1.

Explanation:

Here there are 3 fork system calls in the given program.

new process created = 2n – 1= 23 – 1 = 7

At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions: 1. If program P is to be operated on a day, V can’t be operated on that day. 2. If Q is to be operated on a day, T must be one of the programs to be operated after Q. 3. If R is to be operated on a day, V must be one of the programs to be operated after R. 4. The last program to be operated on any day must be either S or U. If the program sets R and W are to be operated on the first day, which of the following could be the other program on that day?

A wire tension 225 N produces 6 beats per second when it tuked with a fork, when the tension changed to 256 N, it again tuned with the same tuning fork to no. of beats remained unchanged, the frequency of tuning fork will be :
Let’s say we can hear a beat frequency of 2Hz from two tuning forks. The first tuning fork has a frequency of 100Hz. If wax is applied on the 2nd tuning fork, the beat frequency becomes 4Hz, what is the frequency of the 2nd tuning fork?
