OSI Model - Open Systems Interconnection model
When two device want to communicate, there is certain process or layout fro data transmission, This Process is said to be as OSI Model.
OSI Model is represented in terms of Layers
Layer 1 (Physical) - It deals with Physical connectivity as cables, wires and electrical signals in the form of 0's and 1's
Layer 2 (Data-link) - This is the layer where the Ethernet Frames lives. It deals with MAC-Address. The Unit used here is Frames.
Layer 3 (Network) - This deals with Inter-Network. This is the Place where the IP Address Lives. The Unit used here is Packets.
Layer 4 (Transport) - When two device need to communicate they need a Layer 4 (It is way of communication). The unit used here is Segmentation. It may be TCP and UDP.
Layer 5 (Session) - Establish, Manages and Terminates connections NFS, NetBios names, RPC, SQL
Consider, you are opening two tabs in Browser, and searching for google in both tabs, when you close one Tab, Other Tab should not Close, Session layer maintains this session.
Layer 6 (Presentation) - The way in which the user is viewing the Page (ASCII, Jpeg, pdf)
Layer 7 (Application) - This is the Layer, the user contacts directly contacts with. (Http, Https, ftp, SNMP)
TCP/IP Model
The process remains the same the same as compared to OSI and TCP/IP model, but TCP/IP model has only 4 layers
Difference between OSI and TCP/IP model

That's it.
