Explain different characteristics of computer?
1 answer:
The characteristics of computer are speed, accuracy, reliability, Automaticon, Memory
Speed=A computer works with much higher speed and accuracy compared to humans while performing mathematical calculations. Computers can process millions (1,000,000) of instructions per second. The time taken by computers for their operations is microseconds and nanoseconds.
Accuracy=Computers perform calculations with 100% accuracy. Errors may occur due to data inconsistency or inaccuracy.
Reliability=A computer is reliable as it gives consistent result for similar set of data i.e., if we give same set of input any number of times, we will get the same result.
Automation=Computer performs all the tasks automatically i.e. it performs tasks without manual intervention.
Memory=A computer has built-in memory called primary memory where it stores data. Secondary storage are removable devices such as CDs, pen drives, etc., which are also used to store data.

Answer:
a.No output is printed on the screen
Explanation:
As is the function an error will be printed because fork() is not declared in the scope, to define an output we need to see the full content of the code; because 'value' is an integer the 'printf' function is not well defined and the library for execlp is not defined; in general, this code will throw multiple errors in execution.
