A more thorough explanation:

Definition: Public service refers to services provided or facilitated by the government for the general public's convenience and benefit. It can also refer to work performed for or on behalf of the government.

Examples:

• Police and fire departments
• Public schools and libraries
• Public transportation systems
• Government-run healthcare facilities

These examples illustrate how the government provides services that benefit the public. Police and fire departments protect citizens and their property, public schools and libraries provide education and resources, public transportation systems make it easier for people to get around, and government-run healthcare facilities provide medical care to those who need it.
