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

What impact would this have on your personal life or business communications? Personal information and business will slow down due to each vendor having its own standards/protocols. It will also be more vulnerable to attacks and make accessing more difficult. 3.1.2 Give another example of a model that is used to visualize something

1: Networking models Review: The two networking models are TCP/IP which had 5 different layers and the OSI model which has 7 layers. They mainly incorporate the same layers and the only difference is that the TCP/IP layer combines layers 5‚ 6 and 7 all into layer 5. Both models are along the same line of information and both explain how a network moves data. 3.2: OSI reference model: The OSI model includes two more layers that the TCP/IP layer already had but is constructed in only layer 5.

Unit 7: Internetworking Using TCP/IP: Part 2 Abstract IP uses the Address Resolution Protocol‚ ARP‚ to bind a next-hop IP address to an equivalent MAC address. ARP defines the format of messages that computers exchange to resolve an address‚ the encapsulation‚ and the rules for handling ARP messages. The NAT mechanism allows a site to have multiple computers using the Internet through a single IP address. The User Datagram Protocol provides end-to-end message transport from an application

The WTP runs on top of a datagram service such as User Datagram Protocol (UDP) and is part of the standard suite of TCP/IP protocols used to provide a simplified protocol suitable for low bandwidth wireless stations. Security Layer Wireless Transport Layer Security (WTLS). WTLS incorporates security features that are based upon the established Transport Layer Security

Aim: Comparison 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

WAN allows the transmission of data across greater geographic distances. 3 Major characteristics of WANs • Generally connect devices that are separated by a broader geographical area than can be served by a LAN. • Use the services of carriers‚ such as telephone companies‚ cable companies‚ satellite systems‚ and network providers. • Use serial connections of
