Networking Concepts - OSI Model

Flashcards covering key vocabulary and concepts from the OSI Model lecture.

OSI Model

A conceptual framework developed by the International Organization for Standardization (ISO) that describes how communications should occur in a computer network.

Physical Layer

Layer 1 of the OSI model that deals with the physical connection between devices and the transmission of binary digits 0 and 1.

Data Link Layer

Layer 2 of the OSI model that represents the protocol for data transfer between nodes on the same network segment.

Network Layer

Layer 3 of the OSI model responsible for sending data between different networks, handling logical addressing and routing.

Transport Layer

Layer 4 of the OSI model that enables end-to-end communication between applications on different hosts.

Session Layer

Layer 5 of the OSI model responsible for establishing, maintaining, and synchronizing communication between applications.

Presentation Layer

Layer 6 of the OSI model that ensures the data is in a format understandable to the Application Layer, handling encoding and encryption.

Application Layer

Layer 7 of the OSI model that provides network services directly to end-user applications.

MAC Address

Media Access Control address, a unique identifier assigned to network interfaces for communications at the data link layer.

Protocols

Sets of rules that define how data is transmitted over a network.
