Study Notes
Data Transmission
Wired Transmission
- Uses physical medium (copper wires, fiber-optic cables) to transmit data between devices
- Advantages:
- High-speed data transfer
- Low error rate
- Secure
- Disadvantages:
- Limited mobility
- Expensive installation and maintenance
Analog Transmission
- Transmits data as continuous signals (voltage, current, or light)
- Uses modulation to transmit multiple signals simultaneously
- Advantages:
- High bandwidth
- Suitable for long-distance transmission
- Disadvantages:
- Prone to noise and interference
- Limited scalability
Digital Transmission
- Transmits data as discrete signals (0s and 1s)
- Uses encoding and decoding to transmit data
- Advantages:
- High accuracy and reliability
- Error detection and correction possible
- Disadvantages:
- Limited bandwidth
- Requires complex encoding and decoding
Wireless Transmission
- Transmits data through radio waves or infrared signals
- Uses wireless networks (Wi-Fi, Bluetooth, cellular)
- Advantages:
- High mobility
- Easy installation and maintenance
- Disadvantages:
- Interference and security concerns
- Limited range and speed
Optical Transmission
- Transmits data as light signals through fiber-optic cables
- Uses light-emitting diodes (LEDs) or laser diodes
- Advantages:
- High-speed data transfer
- Long-distance transmission possible
- Secure
- Disadvantages:
- Expensive installation and maintenance
- Attenuation and dispersion limitations
Data Transmission
- Data transmission uses physical media, such as copper wires or fiber-optic cables, to transfer data between devices.
Wired Transmission
- Provides high-speed data transfer, low error rate, and security, but limited mobility and expensive installation and maintenance.
Analog Transmission
- Transmits data as continuous signals (voltage, current, or light) using modulation for simultaneous transmission.
- Offers high bandwidth and long-distance transmission capabilities, but prone to noise and interference, and limited scalability.
Digital Transmission
- Transmits data as discrete signals (0s and 1s) using encoding and decoding for transmission.
- Provides high accuracy and reliability, with error detection and correction capabilities, but limited bandwidth and requires complex encoding and decoding.
Wireless Transmission
- Transmits data through radio waves or infrared signals using wireless networks (Wi-Fi, Bluetooth, cellular).
- Offers high mobility and easy installation and maintenance, but interference and security concerns, and limited range and speed.
