Data entry refers to the process of entering, organizing, and recording data into a computer system or database. It involves manually inputting information from various sources, such as paper documents, electronic files, or online forms, into a digital format.

Data entry tasks typically involve typing or copying data from one source to another. The data can include text, numerical values, dates, and other relevant information. Data entry operators or clerks perform these tasks, ensuring accuracy and attention to detail while maintaining the integrity of the data.
