Ethernet uses a bus or star topologyand supports data transfer ratesof 10 Mbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physicaland lower softwarelayers. Ethernet uses the CSMA/CDaccess method to handle simultaneous demands. It is one of the most widely implemented LAN standards iCOM Controls Training and Service Manual •the type of error checking to be usediCOM Control Training and Service Manual There are a variety of standard protocols from which programmerscan choose. Each has particular advantages and disadvantages; for example, some are simpler than others, some are more reliable, and some are faster. From a userspoint of view, the only interesting aspect about protocols is that your computeror device must supportthe right ones if you want to communicate with other computers. The protocol can be implemented either in hardwareor in softwareiCOM Controls Training and Service Manual Understanding IP Addressing: Every computer that communicates over the Internet is assigned an IP address that uniquely identifies the device and distinguishes it from other computers on the Internet. An IP address consists of 32 bits, often shown as 4 octets of numbers from 0-255represented in decimal form instead of binary form. For example, the IP address 168.212.226.204 in binary form is:Network Information iCOM Control Training and Service ManualWhat is networking?… HUBS AND SWITCHESTwisted pair - 10baseT - UTP Cable iCOM Controls Training and Service ManualUNIT IDENTIFICATION OR ADDRESSING How To Use The Schematics iCOM Control Training and Service Manual182769 Liebert DS iCOM Global Control 8 - 12 Ton Electrical SchematicsiCOM Controls Training and Service Manual iCOM Control Training and Service Manual
