Transmission Modes

Transmission Modes

1. Half Duplex Transmission

   • Allows two-way transmissions but the devices don’t transmit at the same time. A system being used to monitor and control manufacturing processes can use half-duplex transmissions. It will send a message to the control computer, which will respond with new settings, but they both cannot send messages at the same time. Some network systems use half-duplex to maximise bandwidth.

2. Full Duplex Transmission

   • Allows two-way communication at the same time. The telephone system, land or mobile, is an example of a full duplex system.

3. Simplex Transmission

   • Sends data in one direction only. A radio broadcast is a good example of simplex transmission.

4. Types Of Stroage Unis

   • Bit (b)
   • Byte (B)
     • 8 Bits in a Byte
   • Kilobyte (KB)
     • 1024 Bytes = 1KB
   • Megabyte (MB)
     • 1024 KB = 1 GB
   • Gigabyte (GB)
     • 1024 GB = 1TB
   • Terabyte (TB)
