About Lesson
Network Representations and Topologies
Explain how host and network devices are used.
Network Representations
- Network diagrams, often called topology diagrams, use symbols to represent devices within the network.
- Important terms to know include:
- Network Interface Card (NIC)
- Physical Port
- Interface
Note: Often, the terms port and interface are used interchangeably
Topology Diagrams
- Physical topology diagrams illustrate the physical location of intermediary devices and cable installation.
- Logical topology diagrams illustrate devices, ports, and the addressing scheme of the network.
