Answer:
d) either e1 or e5
Explanation:
Here, the instruction i1 goes ahead in trying to open the given file through an input stream buffer reader. If the given file name is wrong, it will indicate that an e1 file is not found or if any other IO errors due to invalid stream, no disc in drive e5 IO exception will be drawn.
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:
Mouse
Explanation:
Input devices allow users to input something in the computer. For example keyboard allows users to type on the computer, or mouse allows users to click.
On the other hand output devices allow computers to output data. For example speakers allow us to hear the outputs of a computer.
