Router and Switch Configuration

Router and Switch Configuration When installing, setting, and configuring a switch it is important to know what kind of switch is needed and installed in the network. For this purpose I have chosen the Cisco switches main line, which is the Catalyst Switches, which is one of the popular series and models. They include fixed-configuration desktop models, configurable plug-and-play modular chassis models and packages with high-speed buses into which many cards can be inserted. To configure...

Mainly, a router regulates the fastest outcome possible in a particular network. A router has the ability to allow hosts that are not on the same consistent network, to be able to allow communication with each other. Every router can obtain large portions of data, also known as packets, on an interface. It will then advance the packets...

7 Layers of the Osi Model

The Seven Layers of the OSI Model Kevin Ludwig Bryant and Stratton College TECH 140 Khaled Sabha 12.08.2009 There are seven layers in the OSI model. Each layer has a function or purpose that is used to set up a network. The International Organization for Standardization began to develop the OSI framework in 1984. The purpose was to have each layer interact with the layer directly beneath it. The layers are starting from the top: Application, Presentation, Session, Transport, Network...

Networking Devices

1. Introduction to Network Devices All networks are made up of basic hardware building blocks to interconnect network nodes, such as Network Interface Cards (NICs), Bridges, Hubs, Switches, and Routers. In addition, some method of connecting these building blocks is required, usually in the form of galvanic cable (most commonly Category 5 cable). Less common are microwave links (as in IEEE 802.12) or optical cable ("optical fiber"). An ethernet card may also be required. Network interface cards ...
