power backup system that automatically cuts over to a large diesel motor generator set. The hospital uses a network bridge to interconnect its logical network. A network bridge connects multiple network segments at the data link layer‚ which is Layer 2 of the OSI model. The Data Link Layer enables data to be transferred between network entities and might provide the means to detect and possibly correct errors that may occur in the Physical Layer. The hospital’s network is an Ethernet network. The Ethernet

Data Link Technology Leads The Way The Controller-Pilot Data-Link Communications System is the future of today’s aviation communication. The CPDLC is an example of wireless communications technology‚ which utilizes VHF stations or satellites to transmit data from an aircraft through an air terminal network router‚ which is then received by an air traffic control center. Maastricht’s Flight Data Processing System is a great example of application software technology. This system enables air traffic

The OSI model has seven layers‚ with each having different types of security responsibilities. The seven layers are application‚ presentation‚ session‚ transport‚ network‚ datalink and physical with control being passed down from layer to layer starting with application. The biggest threat to these layers is through people‚ sometimes known as the 8th layer of the OSI model. Companies should take the time to educate their employees on the security threats that each individual brings to the company

book‚ we need to distinguish between logical and physical connections. Chapter 2: Objective (continued) The second section discusses the five layers of the TCP/IP protocol suite. We show how packets in each of the five layers (physical‚ data-link‚ network‚ transport‚ and application) are named. We also mention the addressing mechanism used in each layer. Each layer of the TCP/IP protocol suite is a subject of a part of the book. In other words‚ each layer is discussed in several chapters;
