1. Memory management is concerned with managing the system’s memory resources as the computer runs, allocating space to applications as needed and ensuring that those applications do not interfere with each other. 2. Inter-computer communication is enabled by processor management services installed on both machines 3. Because each layer is functionally independent, layers cannot be combined to form a system. 4. All operating systems are open source; in other words, they are based on open, published source code that can be modified and improved by anyone. 5. UNIX is an example of a proprietary operating system.
A _________ resource is one that can be safely used by only one process at a time and is not depleted by that use.

Implement the bubble sort—another simple, yet inefficient, sorting technique. It’s called bubble sort or sinking sort because smaller values gradually “bubble” their way to the top of the array (i.e., toward the first element) like air bubbles rising in water, while the larger values sink to the bottom (end) of the array. The technique uses nested loops to make several passes through the array. Each pass compares successive overlapping pairs of elements (i.e., elements 0 and 1, 1 and 2, 2 and 3, etc.). If a pair is in increasing order (or the values are equal), the bubble sort leaves the values as they are. If a pair is in decreasing order, the bubble sort swaps their values in the array.
The first pass compares the first two elements of the array and swaps them if necessary. It then
compares the second and third elements. The end of this pass compares the last two elements in
the array and swaps them if necessary. After one pass, the largest element will be in the last position.
After two passes, the largest two elements will be in the last two positions. Explain why bubble
sort is an 
algorithm.
