concept of Power over Ethernet (PoE) was born. This paper provides a research of PoE and its advantages‚ and the fundamental changes brought about by this technology to commercial and industrial applications. An overview of the advancements on the technology is provided as well. The Story behind the success Power over Ethernet or PoE technology describes a system to safely transfer electrical power‚ along with data‚ to remote devices over standard data cables in an Ethernet network (Cat 3/Cat5/Cat5e/Cat6)

Must the company use the Ethernet or Token Ring protocol? Explain your choice. Why is this choice appropriate? In this scenario the best protocol to use would be a token ring because the token ring protocol is mainly used in mainframes. Token Ring uses a token method to go to each work station or main frame that are typically set in a ring or at least

Ethernet vs. Token Ring Topology Ethernet and Token Ring LAN technologies operate in different ways and both systems have their inherent advantages and disadvantages. The decision on which topology to use can be influenced by a number of factors. The most common factors to consider are cost‚ reliability‚ speed‚ size‚ administration‚ security and growth. Ethernet is a frame-based computer networking technology for local area networks (LANs). It defines wiring and signaling for the physical

far about local area networks technologies. 1. Define fast Ethernet. (Minimum word count: 25) Fast Ethernet is a faster version of IEEE 802.3. It promotes the use of Ethernet at 100 Mbps using the same access method. It also can use Fast Ethernet cards that use data rates of both 10 Mbps and 100 Mbps. 2. What type of cable can you use for Fast Ethernet? (Minimum word count: 15) The type of cable that you use for Fast Ethernet is Twisted pair and fiber. 3. What does IEEE 802.15 define? (Minimum

This token passing mechanism is shared by ARCNET‚ token bus‚ and FDDI‚ and has theoretical advantages over the stochastic CSMA/CD of Ethernet. Physically‚ a token ring network is wired as a star‚ with ’hubs’ and arms out to each station and the loop going out-and-back through each. Cabling is generally IBM "Type-1" shielded twisted pair‚ with unique hermaphroditic connectors‚ commonly

Data storage center centers will benefit greatly from the continued evolution of Ethernet. We saw in the past and present how Ethernet protocols enabled faster transmissions of data. How Xerox was able to network thousands of computers to a common printer. We even seen the benefit of collision management introduced in 1971. Data centers will improve the security of the cloud making it more cost effective to have virtual/roaming desktops. This will better enable companies to spend less on sky-scrapers

After researching Cisco resilience solutions and HP IRF resilience solutions I have written this summary report to answer the following 3 questions as per assignment; QUESTION 1 – What are the three primary differences between Cisco layer 2 network resiliency and HP IRF resiliency? The first obvious difference is the protocols that they use. Cisco uses Spanning Tree Protocol (STP) while HP IRF uses the Link Aggregation Control Protocol. The second difference lies in the architecture being used
