Thesis Ethernet and Network Essay

Thesis Ethernet and Network Essay Thesis: Ethernet and Network Essay EVOLUTION OF CAT WIRING CAT-3 Wiring: The original CAT-3 wiring was popular in the early years of the ‘90s. This wiring was unshielded and was utilized in many computer networks, until it was replaced by the similar, but higher-quality CAT-5. CAT-3 had the capacity of carrying data at speeds up to 10MB/sec at a bandwidth of up to 16MHz. CAT-4 Wiring: This wiring never gained much popularity due to the fact that it was quickly unseated by CAT-5, shortly after it was introduced to the market. This wiring had the capacity to transfer data at 16MB/sec at a bandwidth of up to 20MHz. CAT-5 Wiring: This type of wiring was very popular throughout the ‘90s, once when it replaced CAT-3 and CAT-4. Its ability to carry audio and video data made it ideal for computer networks and use in Ethernet cable applications. CAT-5 wiring has the capacity to relay information at speeds of up to 1GB/sec, at bandwidth frequencies of up to 100MHz. CAT-5e Wiring: CAT-5e wiring is an enhanced version of CAT-5 wiring in that it has the same data rate (1GB/sec) and bandwidth frequencies (100MHz), except CAT-5e allows for data to be relayed at distances of up to 1,000 meters. Standard CAT-5 wiring only allows for signal relays up to 100 meters, without the use of devices such as connectors or repeaters, to allow for additional distance. CAT-6 Wiring: CAT-6 wiring was a revolutionary step towards complete cable functionality, with data rates of 10GB/sec at frequencies of up to 250MHz; however, the original CAT-6 is only capable of supporting these requirements over distances of 37 meters or less before it is exposed to alien cross talk. CAT-6a Wiring: CAT-6a is able to support 10GB/s data rates, at a distance of 100 meters. That’s nearly three times the distance of standard CAT-6 cable. Also, CAT-6a cable raised the bar for operating frequency range, allowing for function at bandwidths up to 500MHz. CAT-7 Wiring: CAT-7 cable has provided a more reliable solution to 10GB/sec data rates over 100 meter distances at frequencies up to 600MHz. CAT-7 wire is the closest replacement to fiber optic cable, as far as efficiency goes; however, singlemode fiber optic cable signals have the ability to relay signals across miles and miles, without the use of repeaters. Vocabulary Term | Definition | 1000Base | Ethernet cable with a bandwidth of 1,000 Mbps. Also known as gigabit cable. | 100Base | Ethernet cable with a bandwidth of 100 Mbps. Also known as fast Ethernet cable. | 10Base | Ethernet cable with a bandwidth of 10 Mbps. | Adapter | A part that allows a device to be electrically or physically connected to another device. Network interface cards can be used as adaptors for network cables. | Antenna | An apparatus for sending and receiving radio signals. Wireless routers have an antenna instead of cable. | Backbone | The main line of a communications network that supports all the data being transmitted. | Bandwidth | The amount of information or data that can be sent over a communications channel in a given period of time. The higher a channel's bandwidth, the more information it can carry. | Boundary | The separation point between network segments. Boundaries are usually set by devices that control the data, such as routers and gateways. | Bridge | A hardware device that connect two networks and breaks the segments of one network into smaller groups. Bridges filter incoming traffic and decide whether to forward or discard it. | Bus | A network configuration in which all the nodes are connected to a common line with two endpoints. Bus topology is easy to connect and does not require a lot of cable. | Carrier Sense | The ability of a network device to "listen" to the network to determine if any other devices are trying to transmit data. | Carrier Sensing Multiple Access With Collision Detection | An Ethernet communication protocol in which devices check the network to see if it is clear before transmitting data. | Coaxial Cable |

Can I Learn to Like It essays

Can I Learn to Like It essays Can I learn to like this music and really want to listen to it? This question, or a question of similarity, was asked in my Music 100 class by a fellow student.

The article offers this advice however, By way of caution, do not try to scale Parnassus at a bound. Another words, you need to learn slowly and begin with music that is easier to understand. It mentions selections from Schumanns Album for the Young, and others that offer simpler movements and characteristics easier to listen for. Some of the characteristics it states you should look for are compositions offering attractive melodies, good harmony and pleasing rhythm. The article also discusses a musical idea involving hearing real language within a piece of music. Although it is not mentioned in the article, we have learned in class that this is called word-painting. This involves listening to the music and hearing what is taking place within the story of the music. The article uses the hooves of galloping horses in Schumanns Reiterstuck as ...

DUI class eassy Essay Example | Topics and Well Written Essays - 1000 words

DUI class eassy - Essay Example However, Americans still drink alcohol and drive despite the DUI prevention efforts through DUI laws. This is so as alcohol is deeply rooted in the American culture and way of life. Considering this, there is astonishingly large gap in scientific knowledge regarding the drinking under the influence among the American citizens (Bracken, 2012). It is for this reasons that I have decided to undertake a course in DUI laws. Through this class, I intend to partake in the implementation and formulation of traffic policies within my country. More so, I intend to undertake research on the inconsistencies between law and ethics. Personally, I have been a victim of drunk driving and the incidence nearly landed me in prison. I drove through a police checkpoint before the officers stopped my car and requested me to pull to the side of the road. At first, I was hesitant since I felt that this type of laws should not be applied in a free country. I saw this inspection as an invasion of my privacy and a collapse of American democracy. Before I could explain my case, the officers requested me to get out of the car and asked me several questions before they suspected me of drunk driving. Nonetheless, I was adamant that I had not taken any alcohol. According to my own understanding, being drunk is a personal issue and levels of drunkenness vary across different individuals. Before this incidence, I considered drunk driving an imposition that is meant to invade or violate people’s privacy. The officers requested me to undertake certain tests such as balancing my body on one leg before I took a breathalyzer tes t. Through these tests, the officers concluded that I was drunk and that I had violated the drunken driving laws according to state’s regulation. I was detained in the police station for the night. In addition, my driving license was confisiticated. Although I had never had any
