汇报 means 'to report' and is used for reporting work progress, findings, or information to a superior or team, often in a structured context like a meeting or written summary. It is more focused on systematic work updates than 报告 (bào gào), which is broader (can be a noun for 'speech' or 'lecture'), and differs from 上报 (shàng bào), which specifically means reporting to a higher authority for decisions.
