  8. Terminology • Bit (b), Nibble, Byte (B), Word, LSB & MAB

  9. Terminology • Prefix: kB, MB, GB & TB Example: Number of bytes (B) 1 kB = 1,000 B = 103 B 1 MB = 1,000,000 B = 106 B 1 GB = 1,000,000,000 B = 109 B 1 TB = 1,000,000,000,000 B = 1012B

  10. Terminology • Serial vs. Parallel Communication

  11. Terminology • Frequency (Hz, kHz, MHz & GHz) Number of clocks per second (Hertz, Hz) 1 kHz = 1,000 Hz = 103 Hz 1 MHz = 1,000,000 Hz = 106 Hz 1 GHz = 1,000,000,000 Hz = 109 Hz

  12. Terminology • Bandwidth (BW) Amount of data being transmitted per second (e.g., MB/s, Gb/s) USB 3.0 reaches 5 Gb/s (gigabits per second) PIC Express 4.0 can reach 15.754 Gb/s IEEE 802.11 ad reaches 6.75 Gb/s
