The Internet protocol suite is the conceptual model and set of communications protocols used in the Internet and similar computer networks. Its implementation is a protocol stack. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed , and received. This functionality is organized into four abstraction layers , which classify all related protocols according to the scope of networking involved. The Internet protocol suite predates the OSI model , a more comprehensive reference framework for general networking systems.

Many similarities and differences between them are here. The OSI Model is a conceptual model developed by the International Organization for Standardization that allows various communication systems to communicate through standard protocols. Internet Protocols are the rules set established for network communication. In this article, we have seen differences between both. Here we also discuss the key differences with infographics and comparison table.
It is named from two of the most important protocols in it: the Transmission Control Protocol TCP and the Internet Protocol IP , which were the first two networking protocols defined in this standard. IP networking represents a synthesis of several developments that began to evolve in the s and s, namely the Internet and LANs Local Area Networks , which emerged in the mid- to lates, together with the advent of the World Wide Web in early s. The Internet Protocol Suite, like many protocol suites, may be viewed as a set of layers. Each layer solves a set of problems involving the transmission of data, and provides a well-defined service to the upper layer protocols based on using services from some lower layers. Upper layers are logically closer to the user and deal with more abstract data, relying on lower layer protocols to translate data into forms that can eventually be physically transmitted. The OSI model however is a "generic, protocol- independent standard.
They allow a manufacturer to make devices and network components in which they able to interoperates. Every layer must complete its function before the datagram data unit is passed over to the next stacked layer.

The main purpose of OSI Model was to guide vendors, manufacturer, and the developers so the digital communication products and software programs can interoperate, and facilitate a clear framework that describes the functions of networking or a telecommunication system. Protocols are hidden in OSI model and are easily replaced as the technology changes.
The OSI Model is a logical and conceptual model that defines network communication used by systems open to interconnection and communication with other systems. The Open System Interconnection OSI Model also defines a logical network and effectively describes computer packet transfer by using various layers of protocols. In this TCP Model vs. It helps you to create a virtual network when multiple computer networks are connected together. It is specifically designed as a model to offer highly reliable and end-to-end byte stream over an unreliable internetwork.
