Pd.4 Assignment for 8/24/04Early tools changed how people conducted business and communicated with each other. Back in 1945 John von Neumann wrote “First Draft of a Report on the EDVAC” in which he outlined the architecture of a stored-program computer. The computer was a major change in business, people could store information on the computer and not have file cabinets full of papers.Back then computers werent much help, but they served there purpose. Now a days the computer helps people mostly so they dont have to go searching through a pile of papers just for one thing, instead they could just type in the file name and the computer would bring it up for them.
Back in 1947 Point-contact transistors were the way of contacting one another. In these days 2004 the number of ways of contacting one another is great. We have cell phones, house, and business phones, via e-mail, instant messaging, walkie-talkies and so much more. In 1951 The UNIVAC I delivered to the U.
S. Census Bureau was the first commercial computer to attract widespread public attention. Although manufactured by Remington Rand, the machine often was mistakenly referred to as the “IBM UNIVAC.” Remington Rand eventually sold 46 machines at more than $1 million each.F.O.B. Factory $750,000 plus $185,000 for a high-speed printer. In 1980The first optical data storage disk had 60 times the capacity of a 5 1/4-inch floppy disk. Developed by Philips, the disk stored data as indelible marks burned by a laser that could not be overwritten making it useful primarily for storing large quantities of information that would never need revision. Two years later, Philips created an erasable optical disk using special material, a laser, and magnetism to combine the capacity of an optical disk with the convenience of an option to erase and rewrite.
A laser beam recording a spiral of information on a photosensitive surface produces an optical disk. Two layers of clear plastic protect the metal surface on which the information is recorded. On erasable optical disks, also called magneto-optic disks, the entire metal surface is magnetized in one direction. Technology is gets better and better every year who knows what they will come up with next!
