Seeding
Seeding is the ordering of players before a tournament starts, usually by rating, which decides how pairings are made in the early rounds and who meets whom in a bracket.
Before round one, the organizer ranks the players, normally from the highest rating to the lowest. That ranking is the seeding. In a Swiss event it is used to make the first round pairings, with the field split into halves so that stronger players are matched with players from the other half.
In a knockout bracket, seeding decides the path to the final. The top seed is placed to meet the weakest opponents first, and the strongest players are kept apart until later rounds. This rewards a high rating with an easier route, and it avoids having the two best players meet in the first round.
For students, seeding explains why your first opponents are often much higher or lower rated than you. It also explains why a high seed has the pressure of expectations, while a low seed can play freely. The exact method is written in the tournament rules, and tie situations for equal ratings are settled by the rules the organizer announces, often alphabetical or random order.
How "Seeding" applies to your own results depends on where you stand now, and the improvement plans by rating band show what players near your rating work on.
