A subnetwork, or subnet, is a logical, visible subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. Computers that belong to a subnet are addressed with a common, identical, most-significant bit-group in their IP address.
Introduction. Vasco da Gama was born in 1460 to a wealthy Portuguese family in Sines, Portugal. Vascoâs father was also an explorer and was supposed to make the epic journey from Portugal to India that would eventually make his son famous.
In 1502, King Manuel sent da Gama back to India. This time, however, da Gama came with 20 armed ships to prevent problems with Muslim traders. In one case, da Gama ordered the massacre of a Muslim vessel with 380 people on board.
