Answer: Through the use of close-ended questions, for example a question with a YES/NO answer.
Explanation:
Close ended questions are questions in which a participant has already been provided with options to a question, and so the participants must choose from the options and cannot give an answer outside the options given.
Using this kind of question to modify the database schema would be helpful.
Therefore, in order to affirm that the volunteers are not allergic to dogs or cats, the close ended question "are you allergic to dogs or cats" can be used. The volunteers would be provided with a yes or no answer which they must choose from.
This would help in modifying the database schema while affirming whether the volunteers are allergic to dogs or cats.
Answer:
B. Top listeners
Explanation:
Top listeners gives a detailed information about the user who received the most data, downloads the largest size of data or user streaming from the internet.
Hence, when you run your network monitor, your coworker's computer will likely show up on top listeners list.
They won't have an analytics cookie anymore.
No, but seriously it just means that if the user revisits they'll count as a new visitor rather than a returning one, a new cookie will be generated upon their return though. This is essentially what happens when you use private browsing, the tracking cookie is created upon connection and then deleted when the user leaves.
Answer:
The sorting operation
Explanation:
Required
Database operation to view a record in alphabetical order
The operation is sorting.
Literally, this means arranging data in a particular order (e.g. ascending or descending order)
So, after the database has been created, and I need to the arranged list of names of the computer hardware, I will make use of the sorting operation.
Depending on the database management software that I used, the operation can be achieved using SQL queries (e.g. MySQL Workbench) and can also be done manually (e.g. Microsoft Office Access)
<u>Solution and Explanation:</u>
problem2.sh
#!/usr/bin/env bash
# output file name for stdout
FILEOUT='test.out'
echo $FILEOUT
# output file name for stderr
FILEERR='test.err'
echo $FILEERR
# opening test.in and pipe to cmd1 and output of cmd1 pipe to cmd3 and giving file for stdout and stderr
cat test.in | ./cmd1 | ./cmd3 > $FILEOUT 2>$FILEERR
# END OF SCRIPT
# NOTE: it is to make sure all files in same directory including test.in
After running problem2.sh
$ ./problem2.sh
test.out
test.err
