Application Layer ✔✔The seventh layer in the OSI model, enable software programs to
negotiate their formatting, procedural, security, synchronization, and other requirements for the
network.
Presentation Layer ✔✔the sixth layer of the OSI model, serve as translators between the
application and the network, using a common language for different hosts and applications to
exchange data.
Session Layer ✔✔the fifth OSI model layer, coordinate and maintain links between two devices
for the duration of their communication. They also synchronize dialogue, determine whether
communications have been cut off, and if so, figure out where to restart transmission.
Transport Layer ✔✔The fourth OSI model layer, oversees end-to-end data delivery. In the case
of connection oriented protocols, this means data is delivered reliably. They verify that the data
is received in the sequence in which it was sent. They are also are also responsible for flow
control, segmentation, and reassembly of packets. connectionless protocols do not offer such
guarantees.
Network Layer ✔✔The Third layer of the OSI model, manage logical addressing and determine
routes based on addressing, patterns of usage, and availability. Routers belong on this layer
because they use this information to intelligently direct data from sender to receiver.
Data Link Layer ✔✔The second OSI model layer, organizes data received from the network
layer into frames that contain error-checking routines and then can be transmitted by the physical
layer
Physical Layer ✔✔The first Layer of the OSI model, generate and detect signals so as to
transmit and receive data over a network medium. The protocols also set the data transmission
rate and monitor data error rates, but do not provide error correction.
OSI Model Purpose ✔✔To help understand and develop computer-to-computer communications
over a network.
