Guru (. IAST: guru) is a Sanskrit term that connotes someone who is a "teacher, guide or master" of certain knowledge. In pan-Indian traditions, guru is someone more than a teacher, traditionally a reverential figure to the student, with the guru serving as a "counselor, who helps mold values, shares experiential knowledge as much as literal knowledge, an exemplar in life, an inspirational source and who helps in the spiritual evolution of a student." The term also refers to someone who primarily is one's spiritual guide, who helps one to discover the same potentialities that the guru has already realized.

Generic top-level domains (gTLDs) are one of the categories of top-level domains (TLDs) maintained by the Internet Assigned Numbers Authority (IANA) for use in the Domain Name System of the Internet. A top-level domain is the last label of every fully qualified domain name. They are called generic for historic reasons; initially, they were contrasted with country-specific TLDs in RFC 920.
