Osi Model Study Cards

Enhance Your Learning with OSI Model Flash Cards for quick learning



Layer 1: Physical Layer

The lowest layer of the OSI Model that deals with the physical transmission of data over a network. It defines the electrical, mechanical, and functional specifications for network connections.

Layer 2: Data Link Layer

The second layer of the OSI Model that provides error-free transfer of data frames between nodes over a physical link. It is responsible for framing, error detection, and flow control.

Layer 3: Network Layer

The third layer of the OSI Model that handles the routing of data packets between different networks. It determines the best path for data transmission and performs logical addressing.

Layer 4: Transport Layer

The fourth layer of the OSI Model that ensures reliable and error-free delivery of data between end systems. It provides end-to-end error recovery, flow control, and multiplexing.

Layer 5: Session Layer

The fifth layer of the OSI Model that establishes, manages, and terminates sessions between applications. It provides synchronization, checkpointing, and recovery services.

Layer 6: Presentation Layer

The sixth layer of the OSI Model that deals with the formatting and presentation of data. It translates, encrypts, and compresses data for efficient transmission.

Layer 7: Application Layer

The topmost layer of the OSI Model that interacts directly with the user and provides network services to applications. It includes protocols for email, file transfer, and remote login.

TCP/IP Protocol Suite

A set of protocols that form the basis for the modern internet. It includes the Transmission Control Protocol (TCP) and the Internet Protocol (IP), among others.

OSI Model vs TCP/IP Model

A comparison between the OSI Model and the TCP/IP Model, which are two different conceptual frameworks for understanding network protocols and communication.

Network Devices

Devices such as routers, switches, and hubs that are used to connect and manage networks. They operate at different layers of the OSI Model and facilitate data transmission.
