Why would an administrator lower an RF signal on a wireless access point?Increase QoS
Lower interference
Lower the signal to keep it in the building
Make it harder for guests to access the network

Answers

Answer 1
Answer:

1. Increase QoS

Explanation:

The radio bands with lower frequency have relatively large wavelengths that are not as affected by objects such as building, trees, weather events or other features in the troposphere as the higher frequency radiation. General rule for radiation is that the lower the frequency, i.e. the longer the wavelength, the further a signal can penetrate through solid objects or liquids. Hence, when the frequency is lowered on a wireless access point, the signals can travel farther and smoother. Thus, increasing the quality of service.

Explicit location always tells you where user located when they type the query. T or F

Answers

The answer is false.

An Explicit location is a new concept that Google uses when a searcher is performing a local search and includes the location as well. For instance, instead of searching for “hotel”, the searcher could specify the location and search for Washington Hotel. Searching locations in this way clearly shows that you are looking for something in a specific location. An explicit location is treated as the dominant location of the query and may not be the actual location intent of the query.


The answer would be True that the explicit location always tells you where the user is located when they type the query. It's possible that a geographical model was designed that would geneate the localized results based from the query and the location of the person searching. Google for one has an auto-detection location.

For multicore processors to be used effectively, computers must understand how to divide tasks into parts that can be distributed across each core - an operation called:A. graphics coprocessing
B. multiplexer processing
C. arithmetic-logic processing
D. parallel processing

Answers

Answer: parallel processing

Explanation:

Parallel processing is the process by which the processor has the capacity to execute parallel instruction at the same time. This is possible only by assigning the different task to the different cores present in the cpu. So a cpu with multiple cores are able to process multiple task as the same time parallel.
