Answer:
A for loop can be used to make something repeat as many times as you program it to, but a while loop only stops when you complete the task, or a certain condition is met. So, if you program a for loop to fill a bucket six times it will fill the bucket six times.
Answer:
false
Explanation:
you should be but in the same time no
So you don’t get black listed as spam for outgoing mail, and I hope this one is obvious - to make sure the server isn’t vulnerable to hackers and malware.
Answer:
Crosstalk, Jitter, Impulse noise.
Explanation:
Crosstalk is a network error that occurs when one pair of cable causes interference on another pair of cables thereby preventing efficient data transmission.
Jitter may also impair the accuracy of the data being transmitted across network because minute variations in amplitude, phase, and frequency always occur. The generation of a perfect carrier signal in an analog circuit is almost impossible. The signal may be affected by continuous and rapid network gains or phase changes.
Impulse noise (also referred to as spikes) is the primary source of errors in data communications. Impulse noise can be caused by positioning a communications cable near a source of intermittent but strong electromagnetic pulses, such as an elevator motor.
Counter measures
Shielding (protecting wires by covering them with an insulating coating) is one of the best ways to prevent impulse noise, cross-talk.
Amplifiers can be used to increase signal strength since the connection would run across 4 floors.
