When running the debugger (dbx), you may have wondered what the
'deadbeef' is you occasionally see in registers.  Do note, that
0xdeadbeef is a hexadecimal number that also happens to be some kind
of word (the RS/6000 was built in Texas!), and this hexadecimal number
is simply put into unused registers at some time, probably during
program startup.

Compare and contrast a process and a thread?



As a job, a process, or a thread moves through a system, its status changes, often from HOLD, to READY, to RUNNING, to WAITING and eventually to FINISHED. What are some common reasons why these statuses can change? Define in minor detail what each status means.





The Process Scheduler relies on a scheduling algorithm, based on a specific scheduling policy, to allocate the CPU in the best way to move jobs through the system efficiently. Most systems place an emphasis on fast user response time. Your text book refers to these algorithms as "process scheduling algorithms". Please identify at least four (4) of these algorithms and briefly explain each (one to two paragraphs per alogorithm).



Briefly explain the purpose of a PID and then explain how a process is assigned a PID by the operating system?
