A license is an official permission or authorization that allows an individual or organization to perform specific activities. For example, a driver's license permits a person to operate a vehicle legally on public roads. Licenses can be required for various professions, such as medical licenses for doctors or business licenses for companies, ensuring that individuals meet certain standards and regulations. Licenses often come with specific conditions and may need to be renewed periodically. They help maintain safety and quality in various fields, protecting both the public and the professionals involved. Without the appropriate licenses, individuals may face legal penalties or restrictions on their activities.
