<span>Before allowing a person to
operate PWC, check that they meet the minimum age and boater education
requirements for PWC. While near shore, show how to start and re board the PWC properly
and make sure that he has at least 25 hours of PWC operation experience. Be sure
explain how to steer and control the PWC properly.</span>
Answer:
V44 uses Lempel-Ziv-Welch encoding to compress data.
Explanation:
Lempel–Ziv (LZW) created by Abraham Lempel and Jacob Ziv is a universal lossless data compression algorithm. It is an improvement of LZW algorithm.
It makes use of LZ78 algorithms. This algorithm achieve its compression by taking out repeated occurrences of data with references to a dictionary that is built based on the data stream it received as input.
Also, its dictionary pre-initialized with all available possible characters and symbols.

Answer:
a. 100.
b. 31500.
Explanation:
So, we are given the following data which is going to help in solving this particular question.
The time required to execute (on the average) = 1/2 microsecond , a page fault takes of processor time to handle = 250 microseconds and the disk time to read in the page = 10 milliseconds.
Thus, the time taken by the processor to handle the page fault = 250 microseconds / 1000 = 0.25 milliseconds.
The execution time = [ 1/2 microseconds ]/ 1000 = 0.0005 milliseconds.
The number of Pages sent in a second by the disc = 1000/10 milliseconds = 100.
Assuming U = 1.
Hence, the disc transfer time = [2/3 × 1 } + [ 1/3 × 0.25 milliseconds + 15 ] × 2.
=0.667 + 15.083.
= 15.75 millisecond.
Average number of instruction = 15.75/0.0005 = 31500.
