Study Notes
An Introduction to TCP/IP and Network Models
- Linux and UNIX are known for their flexibility, especially in networking, using TCP/IP.
- Networking involves connecting computer systems to share information and resources.
- System and network administrators are responsible for ensuring the availability of computer resources.
- Different types of networks include LAN, WAN, CAN, and MAN.
- LANs are collections of interconnected nodes in close proximity, but this can also include layer 2 routing.
- WANs are collections of interconnected nodes that are geographically dispersed, often using high-speed media.
- CAN refers to LANs or WANs that extend across multiple buildings within the same company or university.
- MAN refers to nodes within a metropolitan area under the same corporate control.
- The definitions of LAN, WAN, CAN, and MAN can be fuzzy and may evolve with technology.
- A network model, such as TCP/IP or OSI, reflects a design or architecture for communication between systems.
- The OSI model consists of seven layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical.
- Each layer in the OSI model has specific functionality and protocols for implementing tasks.
