what is installation

Installation refers to the process of making hardware and/or software ready for use. It is the act of putting something in a position so that it can work properly. In the context of computer programs, installation involves making the program ready for execution by configuring the software or hardware to make it usable with the computer). An installation program or installer is a computer program that installs files, such as applications, drivers, or other software, onto a computer). The installation process usually requires a user to attend it and make choices, such as accepting or declining an end-user license agreement (EULA), specifying preferences such as the installation location, supplying passwords, or assisting in product activation). In graphical environments, installers that offer a wizard-based interface are common). There are two types of installation: attended and unattended. Attended installation requires user interaction during its progress, while unattended installation does not require the user to supply anything or has received all necessary input prior to the start of installation).
