Study Notes
Communication Links
- Wireless, fiber optics, and copper media are used in communication links, but satellite media is not used.
- The transmission rate of a link is measured in bits per second (bps).
Network Components
- End systems are connected together through networks.
- Packet switches forward packets between networks.
- The network core is responsible for forwarding packets between different networks.
Data Transmission
- Segmenting data at the sending end system breaks it into smaller packets for efficient transmission.
- Packets are forwarded through packet switches to reach the destination end system.
Network Fundamentals
- A protocol is a set of rules and standards that govern data transmission over a network.
- Access networks provide connectivity to end systems, allowing them to access the network core.
