TCP/IP protocol suite and OSI model

When it comes to computer networking, two models are often used as a basis for understanding how different networking protocols and technologies fit together: the OSI (Open Systems Interconnection) model and the TCP/IP (Transmission Control Protocol/Internet Protocol) protocol suite. In this article, we’ll introduce these two models and explore how they relate to each other.

OSI Model:

The OSI model is a conceptual framework that describes how different networking protocols and technologies should be organized and structured to allow communication between different devices. It is organized into seven layers, each with its own set of protocols, services, and functions:

1. Physical Layer: This layer defines the physical characteristics of the network, such as the type of cabling, signaling, and data transmission rates.
2. Data Link Layer: This layer is responsible for providing error-free transmission of data between two devices on the same network. It includes protocols for data framing, error detection, and flow control.
3. Network Layer: This layer is responsible for routing data between different networks, and for addressing and identifying devices on the network. It includes protocols such as IP (Internet Protocol), ICMP (Internet Control Message Protocol), and ARP (Address…
