a user calls to report that she's unable to log on to e-mail, and you ask a cou-
ple of questions. because you know that no one else is using the network right
now, you can't determine whether the problem is unique to her machine or
affects the entire network. probing further, you learn that she's also unable to
print. you decide this problem is probably easier to troubleshoot from the
user's computer.
using the eight-step problem-solving process covered in this chapter, outline
the items you must check and the questions you must ask when you arrive
at the user's office. based on the possible responses to your questions, describe
the actions you will take to correct potential causes of this problem.

Select the correct answer. larry finds it easy to run legacy programs and applications in a virtualized environment. how does the virtualization provider make this possible? a. combines workloads of several underutilized servers to fewer machines b. installs and runs different versions of an operating system on the same computing device c. moves virtual machines from one server to another server at a different location d. streamlines and automates management tasks

1. the program must provide following functions to extract some statistics. note that the data_list parameter specified in these functions may be the same for all functions or different for different functions—that is your choice. a skeleton file is provided on mirmir. a) open_file()prompts the user to enter a year number for the data file. the program will check whether the year is between 1990 and 2015 (both inclusive). if year number is valid, the program will try to open data file with file name ‘year.txt’, where is the year. appropriate error message should be shown if the data file cannot be opened or if the year number is invalid. this function will loop until it receives proper input and successfully opens the file. it returns a file pointer and year. i. hint: use string concatenation to construct the file name b) read_file(fp)has one parameter, a file pointer read. this function returns a list of your choosing containing data you need for other parts of this project. c) find_average(data_list) takes a list of data (of some organization of your choosing) and returns the average salary. the function does not print anything. hints: i. this is not the average of the last column of data. it is not mathematically valid to find an average by finding the average of averages—for example, in this case there are many more in the lowest category than in the highest category. ii. how many wage earners are considered in finding the average (denominator)

When is an original work considered public domain? a. when posted via social media b. when it is posted on the internet c. when a copyright symbol is not included with the piece of work d. when explicit permission is given by the author / owner
