PASV stands for "passive," which is a term frequently used in the context of FTP (File Transfer Protocol). Passive mode is when the client initiates a connection to the server and requests a data transfer. In FTP, there are several synonyms that can be used for "PASV," including "inactive," "quiet," and "restrained." These words convey a sense of calmness and stillness, which reflects the way that passive mode operates. Other synonyms for "PASV" include "submissive," "mild," and "meek." All of these words convey a sense of submission or yielding, which again reflects the way that passive mode is designed to function, allowing data to be transferred without too much disruption or interference.
