Installation refers to the process of setting up a system, software, or equipment so that it is ready for use. This can involve downloading and configuring software on a computer, assembling furniture, or connecting appliances. Proper installation ensures that everything functions correctly and safely, making it an essential step in using new products. In the context of technology, installation often includes steps like checking system requirements, following prompts, and troubleshooting any issues that arise. For example, when installing a new application on a smartphone, users may need to grant permissions and adjust settings to optimize performance.
