Wireless networks experience such a great reduction in actual throughput compared with their respective theoretical throughputs, because wireless networks experience a high number of collisions and require greater overhead on each transmission. The throughput varies significantly from the theoretical maximum speeds due to:

distance from the access point, physical obstructions, such as walls, signal-blocking or reflecting materials which affect signal propagation and reduce speed , interference - other wireless networks and devices in the same frequency in the same area affect performance and shared bandwidth - available bandwidth is shared between all users on the same wireless network.

Byte pair encoding is a data encoding technique. The encoding algorithm looks for pairs of characters that appear in the string
erica [24]

Answer:

C. Byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.

Explanation:

Byte pair encoding is a form of encoding in which the most common pairs of consecutive bytes of data are replaced by a single byte which does not occur within the set of data.

For example, if we has a string ZZaaAb, it can be encoded if the pairs of string ZZ are replaced by X and the second pair by Y. So, our data now becomes XYAb.

To get our original data, that is decode it, we just replace the data with the keys X = ZZ and Y = aa thus allowing our original data to be restored.

Since our original string is restored without loss of data, it implies that <u>byte pair encoding is an example of a lossless transformation because an encoded string can be restored to its original version.</u>
