... were equipped with modems, which allow for connection to on line services via telephone lines. The primitive start of the computer came about around 4000 BC; with the invention of the abacus, by the Chinese. It was a rack with beads strung on wires that could be moved to make calculations. The first digital computer is usually accredited to Blaise Pascal. In 1642 he made the device to aid his father, who was a tax collector.

... Cape Canaveral in Florida, NASA's Wallops Flight Center in Virginia, or, for polar orbiters, Vandenberg Air Force Base in California. One satellite in 20 is crippled by the jolt of lift-off, or dies in the inferno of a defective rocket blast, or is thrust into improper orbit. A few simply vanish into the immensity of space. When a satellite emerges from the rocket's protective shroud, radiotelemety regularly reports on its health to round-the-clock crews of ground controllers. They watch over the temperatures and voltages of the craft's electronic nervous system and other vital "organs", always critical with machi ...

... links. Fortunately, the Net is not usually under enemy attack. The ARPANET was very successful, and every university in the country wanted to sign up. Because so many people wanted to use the Net, ARPANET started getting hard to manage, especially with many university sites on it.

All the networks con ...

... the way by a third party, they will only have unreadable data and will have gained nothing, unless they can figure out the decryption algorithm and obtain the key. This is why the key is never to be sent with the message, and has to be kept secret at all cost. If the key is compromised, the sender and the encrypted data is no longer safe. The sender and the receiver then usually agree on a new key to prevent any further damage. In ancient Greece, around 550 Bc, messages were sent encoded to generals and could only be decoded using special staff keys. The key actually consisted of a physical object, which was appli ...
