8 Inch Floppy Disk
IBM introduced the 8-inch floppy disk, initial capacity was about 100K bytes.
I used this because it was basically a storage device. -
First Email Sent
The first e-mail is sent. Ray Tomlinson of the research firm Bolt, Beranek and Newman sent the first e-mail when he was supposed to be working on a different project. Tomlinson, who is credited with being the one to decide on the "@" sign for use in e-mail, sent his message over a military network called ARPANET. When asked to describe the contents of the first email, Tomlinson said it was “something like "QWERTYUIOP"”.
I chose this because the first email is a big break-through in technology. -
Introduction to touch screen
This was the first widely deployed touch screen technology. It sensed position by the finger interrupting light beams that ran parallel to the surface of the computer screen. -
Apple Computer
Steve Wozniak and Steve Jobs build the first Apple computer. A subsequent version, the Apple II, is an immediate success. Adopted by elementary schools, high schools, and colleges, for many students the Apple II is their first contact with the world of computers. -
3 1/2-inch floppy disk
In 1980, Sony introduced the 3 1/2-inch floppy disk. Initially holding about 400K, current capacity is 1.4Meg per disk. -
Cordless Keyboard
The PCjr computer, announced in 1983, and shipped in January 1984, employed a battery-powered cordless keyboard that employed IR technology. It was presented as working within a 6-foot range, however, like virtually all IR-based mice and keyboards to follow, it had limited success because it required unobstructed line-of-sight to operate (something frequently problematic on a desk-top). -
Microsoft
Microsoft shipped Windows 3.0. The first successful version of Windows finally offered good enough performance to satisfy PC users. For the new version, Microsoft revamped the interface and created a design that allowed PCs to support large graphical applications for the first time. -
World Wide Web
Tim Berners-Lee develops the World Wide Web. CERN releases the first Web server.
I used this because the world wide web is very important in our lives. -
Pentium microprocessor is released
The Pentium introduced several advances that made programs run faster such as the ability to execute several instructions at the same time and support for graphics and music.
I chose this because having faster programs and being able to have music on our computer is a big deal for us. -
Yahoo
Yahoo is founded. Founded by Stanford graduate students Jerry Yang and David Filo, Yahoo started out as "Jerry's Guide to the World Wide Web" before being renamed. Yahoo would quickly expand to become one of the Internet’s most popular search engines.
