Answer:

When Δ is set to large value, then a process's resident set is overestimated and this might prevent many processes from being scheduled even though their required pages are resident

Explanation:

When Δ is set to a small value, then the set of resident pages for a process might be underestimated, allowing a process to be scheduled even though all of its required pages are not resident.

This could result in a large number of page faults. When Δ is set to large value, then a process's resident set is overestimated and this might prevent many processes from being scheduled even though their required pages are resident.

Hoewever, once a process is scheduled, it is unlikely to generate page faults since its resident set has been overestimated.

When you pass an array as an argument to a function, the function can modify the contents of the array?
taurus [48]
In most languages. Primitive data types ( char, int, float, bool, maybe string ) are usually passed by value, but compound data types are passed by reference, so you're not working on a copy but on the original.
