A user opens an application that is installed locally on a PC. The application connects directly to a database that is located on a server in a data closet in the same building. Which of the following application architecture models does this describe?
Which of the following is the least expensive way for users at a large company to load a 2GB spreadsheet quickly?
Adding more RAM to each workstation is the least expensive and most effective way to improve the performance of loading large files like a 2GB spreadsheet. RAM directly impacts how much data a workstation can hold in memory for fast access, and increasing it will help the spreadsheet load and process more quickly. Other options, like upgrading switches or moving to a shared database, may be more costly or less effective.
A . Buy faster networking switches may improve network speed but does not directly affect the local file processing speed.
B . Upgrade the operating system and applications may help, but adding RAM is typically a more cost-effective solution.
C . Move the file to a shared database is unnecessary for a single spreadsheet file.

A programmer needs to specify how to store a test score entered using a web form. Which of the following would be best to use?
A variable is the best option to store a test score entered using a web form. In programming, variables are used to store data values that can change over time, such as user input. The variable can be set to store the score when the user submits it, allowing the program to manipulate or display the score later as needed. Reference: The use of variables for data storage and manipulation is a basic programming concept covered in CompTIA IT Fundamentals and other introductory programming courses.
