远程 (yuǎn chéng) means 'remote, long-distance' and is used specifically in technology and communication contexts — e.g., 远程教育 (remote education), 远程监控 (remote monitoring). Unlike 长途 (cháng tú), which refers to physical long-distance travel or calls, 远程 describes connections made via networks or systems. It is also distinct from 偏远/边远 (piān yuǎn / biān yuǎn), which describe locations far from urban centers.
