OSI and TCP IP model-Computer networks

In this pdf there are examples and detailed concepts related to computer networks and regarding OSI and TCP IP models.You will be able to learn the use and use of OSI and TCP IP models.

OSI Model & TCP/IP Model (Data Communication and Networking)

OSI or Open System Interconnection model was developed by International Standards Organization (ISO). It gives a layered networking framework that conceptualizes how communications should be done between heterogeneous systems. It has seven interconnected layers. The seven layers of the OSI Model are a **physical layer, **data link layer, **network layer, **transport layer, **session layer, **presentation layer, and **application layer.

Process-to-Process Delivery: UDP, TCP, and SCTP

The transport layer is responsible for process-to-process delivery—the delivery of a packet, part of a message, from one process to another. Two processes communicate in a client/server relationship, as we will see later. The transport layer is responsible for process-to-process delivery.
