SUB meaning in Computing ?

Answer: What is Subaddress mean?

An email address identifies an email box to which messages are delivered. While early messaging systems used a variety of formats for addressing, today, email addresses follow a set of specific rules originally standardized by the Internet Engineering Task Force (IETF) in the 1980s, and updated by RFC 5322 and 6854. The term email address in this article refers to addr-spec in RFC 5322, not to address or mailbox; i.e., a raw address without a display-name.

An email address, such as john.smith@example.com, is made up from a local-part, the symbol @, and a domain, which may be a domain name or an IP address enclosed in brackets. Although the standard requires the local part to be case-sensitive,it also urges that receiving hosts deliver messages in a case-independent manner,e.g., that the mail system in the domain example.com treat John.Smith as equivalent to john.smith; some mail systems even treat them as equivalent to johnsmith. Mail systems often limit the users' choice of name to a subset of the technically permitted characters.

With the introduction of internationalized domain names, efforts are progressing to permit non-ASCII characters in email addresses.
