Answer:
The correct answer is BC → A, A does not hold over S. we noticed the tuples (1 ,2 ,3 ) and (4 ,2 ,3) which can hold over S)
Explanation:
Solution
No, since in this case the instance of S is provided. so such particular dependencies are unable to breach through such instance, but unable to tell which the dependencies hold towards S.
A functional dependency holds towards only when a relation forms a statement regarding the complete allowed instances of relation.
Answer:
Troubleshooting
Explanation:
These actions are called troubleshooting.
Troubleshooting is used to diagnose the unexpected error while you are performing some action on the computer. For example
You are running skype, and a one-day mic or sound performing unexpected error. What will you do? You have to perform the troubleshooting for MIC and sound to diagnose the problem.
During troubleshooting, you will wizard through steps of the procedure to diagnose the problem step by step. If the problem will be identified, the solution will be suggested.
You may experience sometimes your Wifi router at home not working. For this to identify the unexpected error you will perform the troubleshooting.
In short, troubleshooting is used to diagnose unexpected error while performing some action on the computer. If troubleshooting does not work, then close all the programs running on your machine, then shut down your computer. Wait a couple of minutes, and then start your computer and see, the problem may have been alleviated.
The limpel-ziv (lz77) compression technique is used by the GNU zip (gzip) tool to produce a compression ratio of 60–70%.
<h3>How do methods for data compression function? Describe the LZW algorithm.</h3>
Compression methods lower the amount of memory needed to hold pictures and the number of bytes needed to represent data. Compression improves the amount of data that can be delivered over the internet and enables the storage of more photos on a given media.
Abraham Lempel, Jacob Ziv, and Terry Welch developed the table-based lookup technique known as LZW compression to compress a file into a smaller file. The TIFF image format and the GIF image format are two frequently used file formats that employ LZW compression.
