Understanding software installation steps

Which of the following best describes the typical first step when installing new software on a computer?

A Running the installer program to copy files and set up the software

B Deleting old files to free up space before installation

C Restarting the computer to prepare for installation

D Creating a backup of all files on the computer

💡 Hint

Trace the effect of uninstalling software

After uninstalling a program, which of the following is the most likely state of the computer?

A All files, settings, and user data related to the program are completely erased

B The program is hidden but still runs in the background

C The program files are removed, but some settings or user files may remain

D The computer automatically deletes all other programs installed after it

💡 Hint

Think about what uninstallers usually remove and what they might leave behind.

Uninstalling software typically removes the main program files, but some settings or user data might remain on the computer unless specifically removed.

❓ identification

advanced

Identify the correct software installation type

Which type of software installation allows the program to run without being fully installed on the computer?

A Full installation

B Portable installation

C Network installation

D Custom installation

💡 Hint

Consider which installation type does not require copying all files to the computer.

Portable installations allow software to run directly from a USB drive or folder without full installation on the computer.

❓ Comparison

advanced

Compare software uninstall methods

Which uninstall method is most thorough in removing all traces of a program?

A Using a third-party uninstaller tool

B Deleting the program folder manually

C Restarting the computer after uninstalling

D Using the program's built-in uninstaller

💡 Hint

Think about which method cleans leftover files and registry entries.

Third-party uninstaller tools scan for leftover files and settings, making them more thorough than built-in uninstallers or manual deletion.

🚀 Application

expert

Determine the outcome of installing software with insufficient disk space

What will most likely happen if you try to install a large software program but your computer does not have enough free disk space?

A The installation will complete but the software will not open

B The software will install partially and run normally

C The computer will automatically free up space by deleting files

D The installation will fail with an error message about disk space

💡 Hint

Consider what happens when there is not enough room to copy all files.

Installers check for enough disk space before copying files. If space is insufficient, they usually stop and show an error.
