Videoconferencing is the conduct of a videoconference by a set of telecommunication technologies which allow two or more locations to communicate by simultaneous two-way video and audio transmissions. Videoconferencing differs from videophone calls in that it's designed to serve a conference or multiple locations rather than individuals.

Floating Point Unit
A floating-point unit is a part of a computer system specially designed to carry out operations on floating point numbers. Typical operations are addition, subtraction, multiplication, division, square root, and bitshifting. Some systems can also perform various transcendental functions such as exponential or trigonometric calculations, though in most modern processors these are done with software library routines.
