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:
Multitasking is a process in which we do multiple task at a time.
In computing system, multitasking is the concept of performing different types of multiple task and process over a certain period of time by executing simultaneously.
Operating system basically allow various task to run simultaneously by the user. In an operating system, each task consume storage system and all the other resources.
Multitasking function facilitate memory isolation in the processor and also supported different levels of security system in the operating system. For example, "a programmer working on any program in a system and as well as listening the music then, it perform multiple task at the same time".
Answer:
In cell B6, formula =INDEX(INDIRECT($B$3),A6)
CallCenter Worksheet Details:
The image of the CallCenter Report worksheet for reference to the question asked is attached below.
Explanation:
Firtsly, an absolute reference in Excel refers to a reference that is "locked" so that rows and columns won't change when copied. To do this,we put a $ dollar sign ( =A$1,) before the row coordinate to lock only the row.
A relative reference in Excel is a cell address without the $ sign in the row and column coordinates example A1.
Having known what absolute and relative reference are, we wlil write the below formula in cell B6 that will later be copied to cell B9:
: =INDEX(INDIRECT($B$3),A6)
Answer:
Content from the web that has been sorted through and shared on a brand’s digital platforms.
Explanation:
This type of content is created by other organizations but shared by a brand because they believe it will be of interest to their audience.
