    E-mail by Ray Tomlinson
    By adding an "@ "sign Ray Tomlinson configured the ability for a message to be sent to multiple computers from a single computer outside of the same mainframe. This ability to communicate through emails could be sent a lot farther than just within the same mainframe. This has become a standard way of communicating almost instantaneously.

    "Floppy Disk" by Warren L. Dalziel
    A data storage device that was almost paper thin stored 80 kilobytes of information. This enabled computer users to save the information and insert it into another computer and retrieve it. We have since evolved to more advanced data storage and retrieval by using flash drives which hold so much more information and are a fraction of the size.
  • "Cell Phone" by Martin Cooper

    "Cell Phone" by Martin Cooper
    Warren L. Dalziel made the very first cell phone without a cord to Motorola's competitor AT&T. TCell phones are the most convenient and instantaneous way to communicate in our world of communication today.
    The first cell phone was about 2.5 pounds heavy. Today they are so light at .29 pounds.
  • "Digital Camera" by Terry Walker, Harry Garland,Roger Melen

    "Digital Camera" by Terry Walker, Harry Garland,Roger Melen
    Terry Walker, Harry Garland, and Roger Melen were photography industry hobbyists who invented this digital camera which was designed as a microcomputer peripheral to begin with. The digital camera has been very key in transmitting images digitally through email in various communication fields.
  • "GPS" Global Positioning System by the U.S. Navy

    "GPS" Global Positioning System by the U.S. Navy
    After landing on the moon, the U.S. launched the NAVSTAR satellite which gave birth to Global Positioning System "GPS". The U.S. Navy had been working on this for a couple of decades. Today this GPS is so imperative for more than exclusive military operations but expands to tracking our devices, loved ones, and pets to finding pretty much anything or place we are looking for.
