What are the most common types of networks in terms of geographic area from smallest to largest? Personal Local Campus Metropolitan Extended Personal Area Network (PAN) Generally associated with an individual work-space LAN Generally associated with all or some of the space within a building. Campus Area Network (CAN) Created by linking LANS located in 2 or more buildings Metropolitan Area Network (MAN) Linking networks located at 2 or more sites located within a city. Wide Area Network (WAN) Is created by linking the networks located at two or more sites distributed over geographic distances that extend beyond the span of a single metropolitan area. OSI is.... Open Systems Interconnection ISO (International Organization for Standards) developed OSI. OSI is a process for? Classifying the process for message exchange associated on a network. What is the objective for OSI model? To provide a structured approach for the development of all types of networks. What are the OSI layers? Layer 1 - 7 OSI Layer 1 Physical Layer. Responsible for transfer of bits over various media. OSI Layer 2 Data Link Layer. Hardware.... NIC cards OSI Layer 3 Network Layer. Router.... Switch OSI Layer 4 Transport Layer OSI Layer 5 Session Layer OSI Layer 6 Presentation Layer OSI Layer 7 Application Layer Acronym for OSI Layers 1-7 P - Please (Physical) D - Do (Data) N - Not (Network) T - Take (Transport) S - Sales (Session) P - Peoples (Presentation) A - Advice (Application) In the OSI Model each layer provides services to the layer..... Above...... while hiding from that layer the processes used to implement the services. How are the OSI layers described as being connected to each-other? Vertical form or stacked Protocol Stacks have the following characteristics..... Each layer provided a set of services Services of each layer and the stack are defined by protocols. Lower layers provide services to upper layers. Service access points are the connection points between layers. What is the relationship called when a message needs to be transferred between 2 systems? Peer to Peer relationship What devices are covered under network hardware? Stations Servers Switches Routers
