What are the benefits of LinkedIn?

I’ve been told by a lot of people that I need to join LinkedIn in order to network and find a job. But I’m not really sure what LinkedIn is or how it can help me. Can someone explain?

The benefits of LinkedIn are many and varied, but some of the most popular reasons for using the site include networking with other professionals, building relationships, and finding a job. LinkedIn can be a great way to connect with other people in your field, learn about new opportunities, and get your foot in the door with potential employers. Additionally, LinkedIn is a great way to stay up-to-date on industry news and trends.
