When you're working with a spreadsheet program, what happens when you type a character on your keyboard?
Explanation:
When you type a character on your keyboard while working with a spreadsheet program, the operating system is the first to be notified that a key has been pressed. It then passes this information to the spreadsheet program. This allows the program to register the keystroke and perform the appropriate action, such as entering data into a cell or executing a command. The operating system acts as an intermediary between the keyboard input and the spreadsheet program, facilitating communication between the two.
When you buy a new computer, which of the following is most likely pre-installed on your computer?
Explanation:
When you buy a new computer, it is most likely pre-installed with the operating system.
