Answer:

A. There is no algorithm to decide whether this can be done or not.

Explanation:

We should respond to the manager who assigned this task that there is no algorithm to decide whether this can be done or not. This is because there are many unknowns with the program that is provided. There are various programming languages and each one has its own structure and requirements in order to test them. Also, each function is created differently with different inputs that are necessary and different algorithms used. It is impossible to design a single algorithm that works to test every single provided program. That is why testers have to create custom test cases for each function.

Given a UNIX file system with 1024-byte blocks, how many disk accesses are needed to access bytes 2500-2503 of a file (assume th
cestrela7 [59]

Answer:

(A) 1

Explanation:

In UNIX the file system the file system is a central part of the operating system. The file system is for storage and retrieval of information. Programs that form the UNIX system also stores information in files.

UNIX file systems supports three files namely: ordinary file, directory files, device files or special files.

If we need to access bytes 2500-2503 it means the bytes are within the third block. So we will need only one access.

Note this is because the file control block (inside) is within the memory. If file control block was not in the memory we would have needed more disk accessses.

To change the print orientation from portrait to landscape, tap or click the ____ button on the print preview tab.
lianna [129]
<span>In certain instances, it makes sense to print documents in landscape orientation. Some examples include spreadsheets and tables, where the content within the document is wider than it is longer. If you print in portrait mode, it would cut off parts of the table or spreadsheet. In this case, you'll want to change the print settings to landscape. To change it to landscape, simply click the "landscape" button on the print preview tab.</span>

Configure the Overlay option.

Explanation:

The reasons behind this answer are that in the first place, creating another calendar is too much work. In the second place, the share of the calendars is not going to help her because that would only allow someone else to watch her calendars. However, using the overlay option will allow her to mix them and create one calendar with all her information.
