The principle is that of ordinary addition; however remember the highest number is 1. Calculate the following: 11001 + 11
How is a process chosen for being swapped either in or out? Swap out: a. If the process is idle. b. If process has been in main memory for a long time.
Developing Code with Threads Writing code to support a thread-based implementation is very straightforward. Simple APIs are presented to the developer for each threads package.
