How can information flow from point A to point B?

Serial vs Parallel Image © Quatec

Example of Serial Comm? Example of Parallel Comm?

Which Mode is More Common? Cost. Less cables. Smaller size. Simplicity. Keeping bits aligned in a high- speed parallel line requires more complex electronics. Serial Why?

The Need for Speed USB 1.0 (12 Mbps) USB 2.0 (480 Mbps) USB 3.0 (4.8 Gbps) Firewire 400 (400 Mbps) Firewire 800 (800 Mbps) SATA (1.5/3.0 Gbps) RS-232 (115.2 Kbps)

Synchronous vs Asynchronous A B A B Synchronous uses a clock line Asynchronous relies on a common clock on each side

RS-232 (Serial Communication) Baud Rate Data bits Start bit / Stop bits Parity

RS-232 Pulses Letter “V” ASCII = 86 ( ) 9600 bps, 8-N-1 Layout: Start Bit, Data Bits, Parity, Stop Bits

How about ASCII 0? Layout: Start Bit, Data Bits, Parity, Stop Bits The data transmission is unbalanced. Can cause transmission errors.

Manchester Encoding (IEEE 802.3) Bit 1 = Low to High Bit 0 = High to Low

Example Image: Wikipedia

Data = 0 Manchester Code
