noun
remote access
Computing term for accessing a computer or network from a distant location.
会社のサーバーに遠隔アクセスして、ファイルを編集した。
I remotely accessed the company server and edited the file.
Synonymous loanword; 遠隔アクセス uses the native 遠隔 (remote) while リモートアクセス is fully katakana. Both are common in IT contexts.
Compound of 遠隔 (えんかく, 'remote') and アクセス ('access'), a straightforward technical term.
