   apt is the newer, friendlier front-end for interactive use, with a progress bar and combined commands such as apt install and apt list. apt-get is the older, stable interface with predictable output, so it is preferred in scripts.

3. What is the difference between apt update and apt upgrade?

   apt update refreshes the local list of available packages and versions from the repositories but installs nothing. apt upgrade then installs newer versions of the packages you already have. Run update first, otherwise upgrade works from stale information.
