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.
Answer: If a customer orders more than four pizzas, the program should deduct 10% from the cost of the order. Modify the program appropriately, and then save, run, and test it.
Answer:
First equation x=4
second equation x=3
Explanation:
The question is telling us that 'X' is equal to 8. It's another way of representing this number using X as the variable replacing it.
We input 8 instead of the X to solve the equation, and here in the picture, you can see where I went from there.
Do the same thing for the other equation.
I hope this helps :)
