The technical term for this form of storage is a stack. You're stacking things from the bottom up and removing them from the top down. It's also called last-in first-out storage, or LIFO. The last thing put on the stack is the first thing taken off the stack. The first thing put on the stack is the last thing taken off the stack.
Computers also can use a stack, not for storing jobs but for storing numbers, and it's something that turns out to be quite convenient. Putting something on the stack is called a push, and taking something off the stack is called a pop.
