Study Notes
OSI Model Layers
- OSI physical layer is responsible for transmitting raw bits across the physical medium.
- OSI data link layer is responsible for framing, error detection, and correction of data transmitted over the physical medium.
- OSI network layer is responsible for routing data between devices on different networks.
Fiber Optic Connections
- Two strands of fiber are used for a single fiber optic connection, one for transmitting and one for receiving data.
Crosstalk
- Crosstalk is a type of electromagnetic interference (EMI) that occurs when a signal transmitted on one cable or channel affects the signal on another cable or channel.
- Shielding or twisting the cables together is a procedure used to reduce the effect of crosstalk in copper cables.
