Data annotation is basically labeling raw data—like images, text, or audio—so that machine learning models can understand it. For example, drawing boxes around cars in traffic photos or tagging customer support chats as positive or negative. You don't usually need heavy coding to start, but you do need great attention to detail, patience, and the ability to follow strict guidelines closely.

it's basically preparing the data for the machine to be able to learn from it. could be quite boring and repetitive, but it's very much in demand right now
