Minicomputer

Minicomputer is a largely outmoded term for a class of multi-user computers which create the middle range of the computing spectrum, in between the largest multi-user systems (traditionally, mainframe computers) and the smallest single-user systems (microcomputers or personal computers). More modern terms for such machines consist of midrange systems (common in IBM parlance), workstations (common in Sun Microsystems and general UNIX/Linux parlance), and servers.

Lighthouse of Alexandria

The Pharos of Alexandria was a big tower built in the 3rd century BC (between 285 and 247 BC) on the island of Pharos in Alexandria, Egypt to give out as that port's landmark, and later, its lighthouse.

With a height variously estimated at between 115 and 150 meters (383 - 450 ft) it was among the tallest man-made structures on Earth for many centuries, and was recognized as one of the Seven Wonders of the World by Antipater of Sidon. It was the third tallest building after the two Great Pyramids (of Khufu and Khafra) for its whole life. Some scientists approximate a much taller height exceeding 180 metres that would make the tower the tallest building up to the 14th century.
