Chapter 1. The TCP/IP and OSI Networking Models Page 1 of 22 Chapter 1. The TCP/IP and OSI Networking Models This chapter covers the following exam topics: Operation of IP Data Networks Recognize the purpose and functions of various network devices such as Routers‚ Switches‚ Bridges and Hubs. Select the components required to meet a given network specification. Describe the purpose and basic operation of the protocols in the OSI and TCP/IP models. Welcome to the first chapter in your

OSI vs. TCP/IP Model Comparison & Overview The Open Systems Interconnection (OSI) reference model created in the late seventies and used today consists of seven layers that include Application‚ Presentation‚ Session‚ Transport‚ Network‚ Data Link and Physical. The Application layer often dubbed Layer 7 is the most common layer to end users and can consist of applications such as Microsoft’s Internet Explorer or other browser software. The Presentation layer provides a translation of application

What is the purpose of an OSI model? The purpose of an OSI model is a standard that was created for networks to share information. This standard governs the way information is transmitted over different networks. The model also sets guidelines to those in the manufacturing industry that create and develop software and hardware that are all compatible with each other. This paper will discuss and describe the 7 layers of the Open System Interconnection model (OSI model) and the layers of the Transport

The two‚ OSI and TCP/IP are Standardized Protocol Architectures developed specifically for: 1. Devices to communicate 2. Vendors to have more marketable products 3. Customers to insist on standards based equipment The OSI is a reference model whilst TCP/IP is the suite which is the most widely used. Description of Open Systems Interconnection (OSI Model) Developed by the International Organization for Standardization (ISO) It is made up of seven layers and each layer: 1. performs a subset of

Difference between OSI model and TCP/IP model The Internet Protocol Suite also known as TCP/IP is the set of communications protocols used for the Internet and other similar networks. 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 1960s and 1970s‚ namely

Between TCP/IP and OSI Reference Model First we discuss‚ what is TCP\IP and OSI model‚ why they are introduced and where they are used. In the following Section OSI Reference models explained with all layers as well as their responsibilities. Open Systems Interconnection model (OSI model): OSI reference model is now considered as a primary standard for internetworking and inter computing. Today many network communication protocols are based on the standards of OSI model. In the OSI model the network/data

Introduction Prior to OSI‚ networking was largely either government-sponsored or vendor-developed and proprietary standards such as SNA and DECnet. In the UK work on the Experimental Packet Switched system circa 1973‚ the need to define so called higher level protocols above the HDLC link level communications protocol and the content of an NCC publication ’Why Distributed Computing’ resulting from considerable research into future configurations for computer systems resulted in the UK presenting

The Internet Protocol Suite is the set of communications protocols used for the Internet and other similar networks. It is commonly also known as TCP/IP 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. Modern IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s‚ namely the Internet and local area networks

About 2.4 billion people use the internet‚ yet there probably is only a small percentage who understands how the internet sends information or where the technology to send the data originated. (Miniwatts Marketing Group‚ 2008) In 1973‚ a paper titled "A Partial Specification of an International Transmission Protocol" was written by Vint Cerf. This paper included a system for more efficiently transmitting information across a network and also included references to TCP or transmission control protocol
