Answer:
Factors that can affect drive thrashing are;
The computer memory modules
Hard drives
Running processes
Paging file
Explanation:
Drive thrashing also known as disk thrashing occurs due to over stressing the hard drives by moving data from the from virtual memory,(paging file) to system memory,(RAM) and back again such that the memory becomes exhausted resulting in slow performance or system halting.
Factors that can affect drive thrashing are the computer memory modules, hard drives, running processes, and paging file
When thrashing occurs, the computer performance is slowed down or halts as the hard drives resources has reached close to capacity.
Answer:
Explanation:
A null pointer is pointing to nothing, if we can detect if a pointer is null, we can use an "IF" because a null pointer always going to be false, a null pointer even can block an application, because is a result of undefined behavior, it can even cause problems because the compiler can’t tell whether we mean a null pointer or the integer 0, there is a confusion in this kind of pointers.
Answer:
5 MB.
Explanation:
1 foot = 12 inches
2400/9=266.66 feet per track
1 track excluding, remaining 8 track =2400 - 266.66 = 2133.33 feet
so, space available to store data = 2133.33 feet
now, 2133.33 feet = 25600 inches
total data that can be stored = 25600 * 1600 = 40960000 bits
= 46080000/8 = 5120000 Bytes
= 5120000/1000000 = 5.12 MB = 5 MB (approx.)
