Key Concepts

MAC Address

A MAC (Media Access Control) address is used at the Data Link layer (Layer 2) of the OSI model. It is a hardware identification number assigned to network interfaces for communications on the local network segment, usually represented in hexadecimal format.

IP Address

An IP address is a unique numerical label assigned to devices on a network at the network layer. In IPv4, it is typically written in dotted-decimal notation, such as '192.168.3.200', and is crucial for routing data packets between devices over a network.

Domain Name System (DNS)

The Domain Name System (DNS) is a hierarchical naming system that translates human-readable domain names into numerical IP addresses. This system operates primarily at the application layer, making network resources accessible via memorable names rather than numeric addresses.

OSI Model

The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and design network communications by dividing functions into seven distinct layers. Each layer has specific responsibilities, from physical transmission to application processing, which facilitates troubleshooting and network design.

Layer-3 Addressing

Layer-3 addressing pertains to the Network layer of the OSI model. This layer is responsible for logical addressing and routing, which includes IP addresses that uniquely identify devices on a network and enable communication across different networks.
