Explanation
Installation is the process of putting something in a position so it can work properly. If the installation of the new dishwasher goes badly, you'll end up with water all over the kitchen floor. Installation is frequently used for appliances and machinery, like the installation of a fountain in your yard or the installation of a fan in your attic to help the house stay cool. You can also use it for people being set up in new positions or jobs: "The installation of a new president has been positive for the university." When artists talk about installations, they mean semi-permanent art exhibits: "The video installation in the museum's elevator is very innovative."
