The history of computers starts out about 2000 years ago, at the birth of the abacus, a wooden rack holding two horizontal wires with beads strung on them. When these beads are moved around, according to programming rules memorized by the user, all regular arithmetic problems can be done. Another important invention around the same time was the Astrolabe, used for navigation. Blaise Pascal is usually credited for building the first digital computer in 1642. It added numbers entered with dials and was made to help his father, a tax collector. In 1671, Gottfried Wilhelm von Leibniz invented a computer that was built in 1694. It could add, and, after changing some things around, multiply. Leibniz invented a special stepped gear mechanism for introducing the addend digits, and this is still being used.

The CPC series uses GPS (Global Positioning System) technology to take the guesswork and effort out of aligning and finding celestial objects in the sky.

This section provides a general overview of DVD technology. Topics covered include a brief history, a comparison of DVDs with compact disc (CD) technology, the different types of DVD that are currently available, and a glimpse at the future of DVDs.
History
DVDs were first developed in 1995 through a consortium of ten companies: Hitachi, JVC, Matsushita, Mitsubishi, Philips, Pioneer, Sony, Thomson, Time Warner, and Toshiba. These companies formed the DVD Consortium, which in April 1997 became the DVD Forum. The mission of the forum is to promote the worldwide acceptance of DVD products across the entertainment, consumer electronics and IT industries. In early 2000, membership in the DVD Forum reached some 230 companies and organizations that are engaged in DVD research, development and/or manufacturing. Although DVD once stood for “Digital Video Disc” or “Digital Versatile Disc,” DVD now simply stands for DVD.
