Communication methods

Communication methods

1. Definitions to learn

   • Bandwidth
     • The range of signals frequencies that a transmission medium may transmit
   • Bit rate
     • The number of bits transmitted per second
   • Baud rate
     • The rate at which signals on a wire or line may change
   • Latency
     • The time delay that can occur between the moment something is initiated and the moment its first effect begins
   • Asynchronous serial data tramission
     • The arrival of data cannot be predicted by the receiver; so a start bit is used to signal the arrival of data and to synchronise the transmitter and reciever temporarily
   • Communication protocol
     • A set of pre-agreed signals, codes and rules to be used for data and information exchange between computers, or a peripheral device such as a printer, that ensure that the communication is successful

2. Hand Shaking

   • Are you ready? Yes I am. Here it is. Busy. That's it. I'm ready again
