OSI Model ( O pen  S ystems  I nterconnection model) The International Standards Organization's OSI model serves as a standard template for describing a network protocol stack. The Protocol Stack Using TCP/IP as a model, the sending application hands data to the transport layer, which breaks it up into the packets required by the network. It stores the sequence number and other data in its header. The network layer adds source and destination data in its header, and the data link layer adds station data in its header. On the other side, the corresponding layer reads and processes the headers and discards them. Upper Layers Layers 7 through 4 comprise the upper layers of the OSI protocol stack. They are more geared to the type of application than the lower layers, which are designed to move packets, no matter what they contain, from one place to another. Application Layer 7 This top layer defines the language and syntax that p...

Power Over Ethernet (POE) Power over Ethernet (PoE) is an established technology that extends the capabilities of Ethernet signaling by providing low-voltage direct current (DC) power delivery to network devices over the same wires that currently carry data. Benefits and Capabilities of PoE PoE offers two benefits that are consistent across applications: cost savings and flexibility of device placement. Because PoE runs data and power together over the same cable to each device attached to the local area network (LAN), devices can be installed without concern for the proximity to individual AC outlets. This saves money by eliminating the cost and time associated with AC outlet installations while providing the flexibility to locate PoE devices where performance is optimum. Additional benefits of PoE include manageability of power sources and battery backups to protect against outages and power spikes. By using a cen...
