Software licensing is a legal agreement that defines how a user can use a software program. It specifies the rights and restrictions associated with the software, such as whether it can be installed on multiple devices, shared with others, or modified. Common types of licenses include proprietary licenses, which restrict usage, and open-source licenses, which allow users to modify and share the software freely. Licenses are important for protecting the intellectual property of software developers and companies. They ensure that users comply with the terms set by the creators, which helps maintain the integrity and security of the software. Violating a software license can lead to legal consequences.
