  3. 3. History<br />Why?<br />The USB was created out of a need for universal communication between devices.<br />The problem with that was that computer designers were literally running out of room<br />Before the USB every new computer device needed a different serial port.<br />
  4. 4. Advantages<br />USB Flash Drive<br />Cost effective<br />Power efficient<br />Universal design<br />One fits all<br />Resistant to scratches and Dust<br />Convenience<br />Size<br />
  5. 5. Disadvantages<br />Size<br />Being to small leaves some devices to be easily misplaced<br />It breaks its gone<br />Compared to some CD’s that can be repaired once scratched to retrieve data USB’s once they fail they fail.<br />
  6. 6. How it Works.<br />Enumeration<br />the computer would decided which kind of data the device uses<br />Interrupt - low data transfer - keyboard or mouse <br />Bulk - large amounts of data - printer or external hard drive <br />Isochronous - streamed data - microphones or speakers<br />
  7. 7. Encoding<br />the process of recoding or modifying information into a desired format or pattern<br />is when the two devices communicate and configure to which form of data transmission should be used<br />
  8. 8. Transmission<br />Convey information from the device to another location.<br />Can be as simple as typing a few keys on the keyboard or transferring large amounts of data like pictures, music and the like<br />
  9. 9. Receiving<br />Recognizes and accepts information from transition and collects the inputs and readies them for storage<br />This would be where the typed keys would be displayed onto the screen or stored in a word document.<br />

  11. 11. Versatility<br />Instruments<br />Microphones<br />Lights<br />Cooling fans<br />
  12. 12. Evolution<br />USB 1.0 – 1.1<br />Maximum transfer rate of 12 mbps<br />First appeared on market in 1995 and 1998<br />
  13. 13. Evolution<br />Hi-Speed USB or USB 2.0 <br />released with speeds of 480 mbps.<br />Released in 2000<br />
  14. 14. Evolution<br />Super-Speed USB or USB 3.0<br /> predicted speeds of 5 gbps<br />Soon to be released.<br />
  15. 15. Future<br />Wireless USB <br />connections you will have the same personal security of wired USB 2.0<br />
