Computer technology has revolutionized the field of geography. Computers are now used in every field, including geography, to perform specific tasks and make work easier. Geography involves the spatial study of the Earth and human interaction, and computers help geographers process, store, and analyze large amounts of geographic data through technologies like GIS and tools that allow for digital processing of satellite imagery. Computers have also improved how geographic research is conducted and taught by facilitating faster data analysis and sharing of information.
