Study Notes
Synchronous and Asynchronous Communication
Parallel Processing
- In parallel processing, multiple tasks are executed simultaneously, improving overall processing speed and efficiency.
- In synchronous communication, parallel processing can be achieved through parallel transmission of data, where multiple signals are sent at the same time.
- Examples: parallel processing in computer architectures, parallel transmission in data storage devices.
Simplex Communication
- Simplex communication is a type of one-way communication where data is transmitted in only one direction.
- The sender transmits data, and the receiver receives it, but there is no feedback or response from the receiver.
- Examples: television broadcasting, radio broadcasting.
Half-Duplex Communication
- Half-duplex communication is a type of two-way communication where data can be transmitted in both directions, but not simultaneously.
- The sender and receiver take turns transmitting data, with one direction at a time.
- Examples: walkie-talkie conversation, some old telephone networks.
Full-Duplex Communication
- Full-duplex communication is a type of two-way communication where data can be transmitted in both directions simultaneously.
- The sender and receiver can transmit data at the same time, allowing for simultaneous communication.
- Examples: modern telephone networks, internet communication protocols.
Latency
- Latency refers to the delay between the time data is sent and the time it is received.
- In synchronous communication, latency can be a critical factor, as it affects the overall performance and responsiveness of the system.
- Factors affecting latency include:
- Distance between sender and receiver
- Transmission medium (e.g., wire, wireless)
- Network congestion
- Processing time at the sender and receiver
Parallel Processing
- Multiple tasks are executed simultaneously to improve overall processing speed and efficiency.
- Achieved through parallel transmission of data, where multiple signals are sent at the same time.
Communication Modes
Simplex Communication
- One-way communication where data is transmitted in only one direction.
