Which of the following is the least expensive way for users at a large company...

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.
