Answer: False
Explanation:
The statement in the question is wrong. When measuring processor speed, a megahertz is slower than a gigahertz.
We should note that:
1 megahertz = 1 million cycles per second
1 gigahertz = 1 billion cycles per second.
Therefore, we can see that a gigahertz is faster than a megahertz.
Answer:
Explanation:
The psychologist, Edward Spector, is expressing his concern for the way teens of this generation are addicted to their phones.
He likens the teens to guinea pigs in an experiment because this is a relatively new field entirely, and such an addiction to technology has never been seen.
Therefore, we are yet to fully ascertain what the effects of being addicted to smartphones truly are, especially the health effects on teenage brains that are still developing.
Answer:
Revisiting "Build a Tower"
Recall in the last section how we made Karel make a tower of tennis balls. We told Karel to move() and turnLeft() and putBall() until we had a tower. At the end of the program, Karel was still at the top of the tower, like as in the picture below.
Stuck at top
Suppose that now we want Karel to come back down from the top of the tower. The first thing we need to do is get Karel facing in the right direction. One way to do this is to tell Karel
turnLeft();
turnLeft();
turnLeft();
And then tell Karel to
move();
move();
move();
back to the bottom of the tower.
However, telling Karel to turnLeft() three times is not very readable. That's a lot of writing when all we really want is to tell Karel to "turn right."

Answer: measures how quickly a system performs a process or transaction
Explanation:
Computer performance refers to how well a given computer system performs, which is estimated by its accuracy, efficiency and speed when completing a process or transaction.
A computer performance evaluation will assess a system's resources and outputs to make sure that it´s performing in the best possible way.
Some parameters of performance are latency, speed, throughput, and bandwidth.
