Study Notes
Physical Media in the Internet
- Physical media used to connect end systems in the Internet include twisted-pair copper wire, coaxial cable, fiber optic cable, and wireless links.
Transmission Rate Measurement
- The transmission rate of a link is measured in bits per second (bps).
Data Transmission
- When one end system has data to send to another end system, the sending end system breaks the data into packets and transmits them to the receiving end system.
Network Core Components
- The two main components of the network core in the Internet are packet switches and communication links.
Types of Communication Links
- Communication links in the Internet are made up of access networks, metro networks, and wide area networks.
Excluded Physical Media
- Satellite links are NOT used to connect end systems in the Internet.
Packet Switch Function
- The function of packet switches in the Internet is to forward packets of data through the network.
Communication Link Measurement
- Communication links in the Internet are measured in bandwidth (amount of data that can be transmitted per unit of time) and latency (delay between transmission and receipt).
Network Edge Purpose
- The main purpose of the network edge in the Internet is to connect end systems to the network core.
Protocol Definition
- In the context of computer networks, a protocol refers to a set of rules and conventions that govern data transmission and communication over the network.
