Answer:
See explaination
Explanation:
class Counter:
def getValue(self):
return self._value
def undo(self):
if self._value > 0:
self._value = self._value - 1;
def click(self):
self._value= self._value + 1
def reset(self):
self._value= 0
tally= Counter()
tally.reset()
tally.click()
tally.click()
result = tally.getValue()
print("Value:", result)
tally.click()
result = tally.getValue()
print("Value:", result)
tally.undo()
tally.undo()
result = tally.getValue()
print("Value:", result)
tally.undo()
tally.undo()
result = tally.getValue()
print("Value:", result)
The answer is column F. During relative copy and paste in Excel, the positioning of the '$' symbol effectively indicated an absolute reference to a position, so that is not updated. Therefore, in the formula '<span>=F$5+12</span>', only column F is updated.
Answer:
Probably would use LAN
Explanation:
Schools use LAN to connect students to their networks, so it would make sense for them to use LAN for offices. They could use ethernet if all their PCs are hard wired in, though.
Answer: d. the time quantum should be as small as possible.
Explanation: Round robin is a CPU scheduling algorithm. If the time quantum is extremely small, number of context switches is very high, round robin scheduling will be same as processor sharing algorithm. Then the algorithm is good. Very large time quantum will make response time of processes too much which may not be tolerated in interactive environment.
