When discussing software, what does the term 'runtime' refer to?

The term 'runtime' specifically refers to the period during which a program is actively being executed. This is the duration from the moment a user starts the program until it is closed or terminated. During runtime, the program carries out its functions, processes data, and interacts with the user and other system resources. This concept is essential in understanding how software operates on a computer.

Other options address different aspects of software and computer operation. The time taken to install software pertains to the installation phase, which is separate from execution. The development process of software relates to the creation and coding phase, which occurs before a program can be executed. Lastly, the time it takes to boot a computer refers to the startup procedure of the operating system and is not related to the execution of individual programs. Each of these processes is distinct and does not align with the definition of runtime, which focuses solely on the active execution of applications.
