The tertiary sector, also known as the service sector, focuses on providing services rather than producing goods. This includes a wide range of activities such as healthcare, education, banking, and hospitality. People working in this sector help meet the needs of individuals and businesses, making it essential for a functioning economy. In many developed countries, the tertiary sector is the largest part of the economy, employing a significant portion of the workforce. As technology advances, new services emerge, such as online shopping and digital marketing, further expanding the importance of the tertiary sector in our daily lives.
