A conference is a formal meeting where people gather to discuss important topics, share ideas, or make decisions together. When teachers attend a conference, they might learn new teaching methods from experts and other educators. When scientists hold a conference, they present their research findings and discuss discoveries with colleagues from around the world.

Conferences usually bring together people who share common interests or work in the same field. A technology conference might feature presentations about new inventions and software. A medical conference helps doctors learn about the latest treatments and techniques. These events often last several days and include speeches, workshops, and plenty of time for attendees to talk with each other between sessions.

The word also describes smaller, more focused meetings. When your principal calls a parent-teacher conference, it's a scheduled meeting to discuss your progress at school. Business executives might hold a conference call, where people in different locations talk together over the phone or video. A press conference is when someone makes an important announcement and answers questions from reporters.

The key idea is that a conference brings people together for serious discussion and exchange of information, whether it's a massive gathering of thousands of professionals or a quiet meeting between a handful of people working on the same problem.
