You should specify what language you're using in these types of questions. Here's an example in C++, which is fairly easy to understand, so you should be able to transfer the concept to another language to problem.
int x = 2, y = 1, z = 3, min;
if (x < y && x < z)
min = x;
else if (y < x && y < z)
min = y;
else if (z < x && z < y)
min = z;
else
std::cout << "There is no minimum";
Ummmmmm......Where is the question?
Answer:
RAM and Hard Drive
Explanation:
An FRU is also called a Field-repleacable Unit and is usually an assembly that is easily removed from an electronic equipment, laptop or just a computer and replaced so that one does not have to take the entire system for repairs. When trying to equip yourself with this unit of a laptop, you must take your Random Access Memory and your hard drive as they contain the whole information on the laptop.
