Which of the following best describes the primary function of software applications?
A. To send and receive email
B. To assist users in performing a specific task
C. To perform math calculations
D. To collect data that can be used to enhance the user experience
Final answer:
The primary function of software applications is to assist users in performing specific tasks, encompassing a broad range of functions including productivity, entertainment, and data management tasks. Software developers commonly work in the tertiary or quaternary sectors of the economy, providing IT and knowledge-based services.
Explanation:
An application program, or app, is a computer program that is designed to perform a specific task beyond that of the computer's operation, usually for end-users. Examples include word processors, media players, and accounting software. Given the options provided in the question, the best description of the primary function of software applications would be to assist users in performing a specific task (Option B).
Applications encompass a wide variety of functions, including but not limited to sending and receiving email, performing math calculations, or collecting user data to enhance experience, but these are all specific instances of the broader purpose of aiding users in tasks.
With regard to the sector of an economy, a software developer would typically work in the tertiary sector, which involves provision of services rather than dealing with primary resources or manufacturing. In some classifications, there might also be a reference to a quaternary sector which includes services such as information technology and knowledge-based services where software development would also fit.
You need a reliable network for about twenty-five computers that will be distributed across a large building. It is important that the network be relatively cheap. Which topology should you use
a mesh topology
a bus topology
a star topology
In this type of topology, every node is connected to a central network device like a switch, router, or a computer. Nowadays, bus topologies are not commonly used and thus not reliable. Both star and Mesh are reliable topologies since a failure of one device does not affect the entire network. However, overall cost of Mesh topologies is way too high as compared to any other network topology making it an undesirable option.

Because excel stores dates and times as _____, you can apply different formats without affecting the date and time value.
Dates and time are treated as serial numbers or integer values
Dates and times are stored in excel as integers or serial numbers. The whole idea of integer representation dates back to the 1st of January 1900, and this is the point in which Excel starts counting. Thus, the number 1, by default, represents January 1, 1900. If we stick to this calculation, a number like 23 will be treated as the 23rd of January 1900 and so on. Regardless of the format, the date and time will be the same no matter what.

In cell i5, enter a formula to calculate the total admission fees collected for the 2018 altamonte springs job fair using a mixed cell reference for cell b14.
Final answer:
Use =SUM(C5:H5)*$B14 in cell I5 to calculate the total admission fees for the 2018 Altamonte Springs Job Fair. The $ sign before B14 implies mixed cell reference, fixing the column but not the row.
Explanation:
To calculate the total admission fees collected for the 2018 Altamonte Springs Job Fair in cell I5 with a mixed cell reference to B14, you will need to use a formula that multiplies the number of attendees or tickets sold (which is presumably in a cell or range of cells like C5:H5) by the ticket price listed in cell B14. Assuming that C5:H5 contains the number of tickets sold for various categories, your formula should look something like this: =SUM(C5:H5)*$B14. The dollar sign before B14 creates a mixed reference, fixing the column but allowing the row to change if the formula is copied to other rows, which means as you copy the formula down, it keeps referring to the ticket price in B14.
If you need to use the total number of tickets from a different row, you would replace C5:H5 with the appropriate cell range. Be sure to adjust your formula accordingly if your data is organized differently.
