Answer:
See explaination
Explanation:
The code
type printer = monitor
var P: array[0…2] of boolean;
X: condition;
procedure acquire (id: integer, printer-id: integer);
begin
if P[0] and P[1] and P[2] then X.wait(id)
if not P[0] then printer-id := 0;
else if not P[1] then printer-id := 1;
else printer-id := 2;
P[printer-id]:=true;
end;
procedure release (printer-id: integer)
begin
P[printer-id]:=false;
X.signal;
end;
begin
P[0] := P[1] := P[2] := false;
end ;
Note:
Monitors are implemented by using queues to keep track of the processes attempting to become active int he monitor. To be active, a monitor must obtain a lock to allow it to execute the monitor code. Processes that are blocked are put in a queue of processes waiting for an unblocking event to occur.

Explanation: just took the test
Answer:
1. so if i wanted to build a linux server for web services(apache) with 1cpu and 2 gb of memory.-operating at 75% of memory capacity2. a windows server with 2 cpu/ 4gb memory- operating at 85% of memory capacity3. a storage server with 1 cpu/ 2gb memory- operating at 85% of memory capacityhow much memory do i have to add for each server. so that the utilization rate for both cpu and memory is at a baseline of 60%."the details for the cpu like its processor or the memory's speed isnt to be concerned" yeah i kept asking my teacher if he's even sure about the but the whole class seems to be confused and the project is due in 3 days..this is a virtualization project where i have to virtualize a typical server into an exsi hypervisor.
