Power over Ethernet

Fire Wire cable is very easy to use. It is a plug and play environment which means that the wire can be used as soon as it is plugged in, no need for system configuration. Using Fire Wire cable is as easy as plugging or unplugging a your computers power cord. There are quite a few benefits of Fire Wire. Fire Wire has faster data exchange rates (100 Mb/s) in comparison to USB 2.0(60 Mb/s). A Fire Wire port can easily be found on most laptops and computers. However there are som down sides to this.

need as it stands today, and adding additional ranges will be very easy to provide for future expansion. DHCP scopes can be added to the server with a few clicks, and further subnets can be added for other facilities or buildings if needed. Voice over IP (VoIP) To address a VoIP solution, we need to examine the benefits, as well as any potential drawbacks and costs. The main advantages of a VoIP system are a decreased run rate, mobility of the phone systems, service functionality including

ability to use Voice over IP. They need to choose a media that would allow them to obtain the speeds needed to meet the object of the business. 3. The third issue: Adding the computers in the class room to the network is the third issue they are facing. They need a solution is scalable and cost effective. 4. Voice over IP is not working properly and connections to the backbone are inadequate. They need a connection that viable for the backbone and equip to handle Voice over IP. Recommendations

In addition, there seems to be some connectivity issues with the backbone of the network. One of the biggest complaints included not being able to use Voice over IP. Therefore, a more suitable media that will increase their network speeds needs to be put into place. A final issue that needs to be addressed is the possibility of adding class room computers to the network. A cost effective, yet scalable solution

computers on the LAN? A star bus topology or a hybrid topology 2. Place the following networking technologies in the order of their highest speed, from slowest to fastest: WiMAX, dial-up networking, cable Internet, Fast Ethernet, 3G Dial-up networking, 3G, cable Internet, WiMAX, Fast Ethernet 3. What is the difference between ADSL and SDSL? ADSL uses one upload speed from the consumer to an ISP and a faster download speed. SDSL uses equal bandwidths in both directions. 4. Among satellite, cable Internet

phones etc. with the right networking specifications allowing them to be connected with each other using a common connecion such as Ethernet or wireless. This establishment allows the sharing of resources from the device through the network and to the desired destination such as another device e.g. Mobile phone, pc, tablet etc. all locally within the network by Ethernet etc. In this scenario the LAN network is used for gaming where two computers connected to the same network are trying to connect with

use secure Ethernet technology. • Implement email. • Detecting sniffers. • Protecting from sniffers. • Protecting from FOSS systems. • Responding to sniffer related incidents • Conclusion. How Sniffers works using Wire shark: References: wire shark website(network forensics.) To comprehend the risk that sniffers show first requires understanding how sniffers work. The way in which sniffers work relies on upon the kind of system. In a mutual media system, for example, a standard Ethernet, parcels

it was introduced. What technology is that? It is Voice over Internet Protocol or VoIP for short. When Alexander Graham Bell invented the telephone in 1876, he had no idea that his invention would morph into what it has become today. This paper is describing how VoIP was created, its industry trends, technological developments, and how VoIP is utilized. (Background A)VoIP is the transmission of voice communications and multimedia sessions over the internet instead of the public switch telephone network

Security Consideration of High Speed Network — 40G/100G Optical Ethernet Ying Shu Chen Xiao Yang Ren Qiu Yang Guo Abstract—The basic ideas and technologies for security of 40G/100G Ethernet are briefly described. Some potential security-related problems referring to physical security and the possible preventive measure, and the information security of its data are analyzed in line with its characteristics. Several practical methods for the enhancement of its information security based on the
