osi model 7 layers

application presentation session transport network datalink physical

application - gui / helps to manage the incoming and outgoing

presentation - standardisation of the data / traslator /security https

session - creates session both sides / sends data in chunks so if the data is lost then it could be resumed

trasport layer - tcp~udp

tcp - transmission control protocol

Three-way handshake

reliability

error checking

uses

file sharing - internet browsing or sending a mail

udp - uniform datagram protocol

network layer

arranges the data /assembly of data

data link



physical

ethernet

love that thanks dude
 
Your breakdown of the OSI model and its 7 layers is mostly accurate. Here's a summary of each layer:

  1. Physical layer - This is the physical layer of the network, which deals with the physical transmission of data over the network, such as Ethernet cables and Wi-Fi signals.
  2. Data link layer - This layer provides error-free transfer of data frames between nodes over the physical layer. It establishes links between devices on the network and handles frame synchronization, flow control, and error checking.
  3. Network layer - This layer provides routing and addressing services so that data can be transferred across different networks. It determines the best path for the data to travel and handles congestion control.
  4. Transport layer - This layer provides end-to-end data transfer services for applications. It ensures reliable data transfer and manages data flow, using protocols like TCP and UDP.
  5. Session layer - This layer establishes, manages, and terminates sessions between applications running on different devices. It handles authentication and security, and provides checkpointing and recovery services.
  6. Presentation layer - This layer translates data into a standard format that can be understood by applications. It handles data encryption and compression, and ensures that data is presented in a format that can be understood by both sender and receiver.
  7. Application layer - This layer provides services to applications that
