  • binary digit
  • Single bit can store one of two digits 1 or 0
  • NIbble is 4 bits
    -Byte is 8 bits
  • data transfer (50 bps / 2 seconds = 25 bps)

Q

USB overview

6

A
  • can daisy chain up to 127 devices per controller (i.e USB hub..)
  • Limitations…
    • Each port is controlled by a host controller
    • Same bandwidth for all devices (5 Gbps max speed with five devices connected all get 1 Gbps)
    • If device doesnt support speed of host controller it will reduce to the speed it does support ( i.e if hub supports 5Gbps and cord/ device plugged in supports 2 Gbps then it will reduce to 2Gbps
  • Longer cables have higher chance of resistance and speed & signal deterioration
  • Shorter cables provide maximum performance

Q

Serial cable

4

A
  • came out before USB
  • Designed to replace USB
  • connected using DB9 most commonly
  • A cable that sends data in ones and zeros in a straight line, but it can only send one bit at a time, which is measured at the speed of cables in bits
    per second

Q

DB9

7

A
  • screwed in
  • called serial because you can only all data sent as 1’s and 0’s
  • speed measure in bps or Kbps
  • fastest 115 kbps
  • mice keyboards, external modems
  • only connect one device
  • designed to replace USB

Q

USB limitations

3

A
  • Longer cables have resistence and signal/speed deterioration (Shorter cables give maximum performance)
  • when plugged into a hub speed is split between ports
  • slowest device will be operating speed of all devices plugged into hub
