Answer:
<!-- Modified by selena ramirez - for html compliance -->
Explanation:
In HTML, <!-- .. --> tag is used to insert comments in the webpage code.
Comments written inside the tag is visible only on the code, and is not displayed in the browsers when the page is requested by the client computer.
<em>Comment tag</em> is useful when there is a lot of code and multiple developers are dealing with the same code.
Comments help developers understand what changed is made and why.
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.
