There are several models for computer networks, each with its own layers and protocols. Here are some of the most common ones:
- OSI Model: The Open System Interconnect (OSI) model is a seven-layer network framework established by the International Standard Organization (ISO). The layers include Application, Presentation, Session, Transport, Network, Data Link, and Physical12.
- Internet Protocol Suite: Also known as the TCP/IP model, this is a four-layer network architecture used by the internet. The layers include Application, Transport, Internet, and Network Interface12.
- Ethernet: This is a wired network protocol1.
- Wi-Fi: This is a wireless network protocol1.
- SSL/TLS: These are encryption protocols1.
- Client/Server Model: In this model, multiple clients connect to a single server3.
- Peer-to-Peer Model: In this model, all computers (peers) share equivalent responsibilities and capabilities3.
