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.
Da Gama went in search of adventure and trade, so many westerners assume that the same motives inspired Zheng He's trips. However, the Ming admiral and his treasure fleet were not engaged in a voyage of exploration, for one simple reason: the Chinese already knew about the ports and countries around the Indian Ocean.
