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

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

Secretary Maria and the OSI Network Model Mr. Boss meets Maria on the 7th floor of the main building headquarters. He gives Maria a secret message that must get to the US Embassy across town. Maria proceeds to the 6th floor where the message is translated into an intermediary language‚ encrypted and miniaturized. Maria then takes the elevator to the 5th floor where she checks the message to be sure it is all there and puts some checkpoints in the message so her counterpart at the US Embassy

This presentation was informational about SIOP. I learned that SIOP stands for Sheltered Instruction Observation Protocol Model. Sarah Eakin stated‚ “SIOP is a research-based and validated instructional model that has proven effective in addressing the academic needs of English learned throughout the United States.” SIOP consists of eight components: lesson preparation‚ building background‚ comprehensible input‚ strategies‚ interaction‚ practice/application‚ lesson delivery‚ review and assessment

Introduction to the OSI Reference Model The International Organization for Standardization (ISO) defined the Open Systems Interconnection (OSI) reference model to standardize networking of devices from different vendors. The OSI reference model is mostly an architecture blueprint that networking and computer device manufacturers implement. The OSI model has never been implemented exactly as defined. The TCP/IP protocol stack is the closest implementation available today. Application Layer (7)

7. How do local area networks (LANs) differ from metropolitan area network (MAN)? A local area network (LAN) is a group of microcomputers located in the same general area. It covers a clearly defined small area‚ such as an office‚ home network ‚one floor or work area‚ a single building‚ or a group of buildings. While a metropolitan area network (MAN) connects LANs and BNs located in different areas to each other and to WANs. MANs typically span between three and 30 miles. For example a large university

The seventh layer of the OSI model is the Application layer. b. Protocols in the Transport layer accept data from the Session layer and manage end-to-end delivery of data. c. True or False: The IP (Internet Protocol) operates in the Transport layer. False d. True or False: Standards help to ensure interoperability between software and hardware from different manufacturers. True e. True or False: Standards define maximum acceptable performance.

Attacks on layer two of the OSI model Seven layers of OSI In 1977 a model called Open Systems Interconnection (OSI) was proposed‚ with the aim to establish an interoperability standard for different vendor products. This model defines several layers related to data transfer‚ from the lowest (physical) to the highest (application) layer. They have a strong dependence upon one another and headers are usually added when traversing from a lower layer to a higher one. The seven layers are: Layer 1 -
