Study Notes
Network Communication
- The network layer is responsible for supporting communications across data networks.
Physical Layer
- The physical layer is responsible for transmitting raw bits over a physical medium, defining cables, Wi-Fi, and network topology.
Characteristics of Physical Layer
- Specifies the physical means of data transmission between devices
- Defines cable specifications, wireless transmission, and network topology
Fiber-Optic Cabling
- The main advantage of fiber-optic cabling over other media is its high speed and resistance to electromagnetic interference.
Device Connection
- Devices can be connected in a network through wired connections (e.g., Ethernet cables) or wireless connections (e.g., Wi-Fi, Bluetooth).
