  • Packet Generator - 971 words
    Packet Generator MOTIVATION / GOALS When it comes to real-world network throughput, there are as many opinions about network performance as there are network installations. Every network site is unique, and the performance of the network is a function of the number of stations contending for access to the Ethernet, the type of hardware in use (station interfaces, switches), the layout of the cables (are they the right type, right length, and do they meet the configuration guidelines?), the quality of the cable installation and the mix of applications. However, with the ever-increasing number of networks, the traffic over the Internet is going to be saturated and performance will be down. In ...

  • Abortion And Prolife - 1,826 words
    Abortion And Pro-Life November 14, 1979, with the temperature outside at fifteen degrees, a two pound baby girl was found in a field wrapped up in a wet, dirty, old shirt. The umbilical cord was still attached, and the baby had been aborted twelve weeks prematurely. With little chance of survival, the baby was taken to a medical center. The little girl survived surgery and other efforts to save her. The baby was later adopted by, Susan Morrison, one of the nurses who attended to her. The baby was named Christelle, and now she and her mother talk to thousands of people about abortion and the pro-life movement (Maffet 13-14). This is an example of one person who felt they had the right to kill ...

    ... before as well as after, birth" (Wilke 94). The unborn are beginning to gain more rights. From state to state, legal rights of an unborn child can mean the difference between the death of a fetus being a criminal act to being just a matter of legal consequence. Mothers are now starting to be prosecuted for harming their babies through drug and alcohol abuse. Drunk drivers are also being punished in some states for injuring fetuses. Accidents like these would have gone without punishment up until a few years ago. Almost half of the states, such as Delaware, do not consider the killing of a fetus as murder unless the child is born and then dies (USA Today). Patricia Bast Lyman added to th ...

  • Arpanet - 652 words
    ARPANET The USSR launches Sputnik, the first artificial earth satellite. In the late 1960s the U.S. military was desperately afraid of a nuclear attack from the Soviet Union. The United States formed the Advanced Research Projects Agency (ARPA) within the Department of Defense to establish a bombproof network to connect military bases. ARPANETs physical network was established in 1969 to enable universities and research organizations to exchange information freely. The first two nodes that formed the ARPANET were UCLA and the Stanford Research Institute, shortly after the University of Utah was added to ARPANET. The Network Control Protocol (NCP) was initially used as the ARPANET protocol, b ...

  • Asynchronous Transfer Mode - 1,094 words
    Asynchronous Transfer Mode Asynchronous Transfer Mode: Asynchronous Transfer Mode By Gene Bandy State Technical Institute Asynchronous Transfer Mode: Asynchronous Transfer Mode(ATM) is a high-speed transmission protocol in which data blocks are broken into small cells that are transmitted individually and possibly via different routes in a manner similar to packet-switching technology. In other words, it is a form of data transmission that allows voice, video and data to be sent along the same network. In the past, voice, video and data were transferred using separate networks: voice traffic over the phone, video over cable networks and data over an internetwork. ATM is a cell- switching and ...

  • Brca Brca - 2,511 words
    Brca1 & Brca2 Are Women More Susceptible to Breast and Ovarian Cancer If a Mutation in BRCA1 and BRCA2 is Found Breast and Ovarian cancer are the two most common kinds of cancers found in women in the United States. An estimated 90-95% of cancer cases are believed to be environmental and lifestyle related. The remaining five to ten percent of these types of cancers may be caused by inherited genetic mutations. The existence of a breast cancer susceptibility gene known as BRCA1 and its approximate location on human chromosome 17 have been known for about 4 years, on the basis of retrospective family studies. But only since 1994 have scientist actually been able to isolate and sequence the gen ...

  • Cable Modems: Cable Tv Meets The Internet - 3,910 words
    ... downstream traffic travels through the cable modem's Media Access Control mechanism. The MAC mechanism's functions are fairly complex. The MAC mechanism's main purpose is to implement MAC protocols under the direction of the CMTS. MAC protocols are used to time-share the cable media among the various cable modems in a cable data network. The MAC processes can be implemented in hardware, or a combination of software and hardware. Both the CMTS and the MAC mechanism implement MAC protocols to perform ranging procedures to compensate for cable media delays and line losses. The CMTS also interfaces with the MAC mechanism in each cable modem to assign upstream frequencies and upstream time s ...

  • Carol Anne Duffys Adultery - 1,091 words
    Carol Anne Duffy's Adultery FORM AND STRUCTURE Carol Anne Duffy's poem "Adultery" is structured in a traditional and straightforward way. It is comprised of eleven verses - each with the common four lines, which consist of between four and nine words. This makes the poem not particularly striking at the first look, before it is read. The typography does not attract the readers attention, this is probably because Duffy wants the reader to concentrate on the language, and is not concerned with the shape that the lines form, or how they relate to the themes of the poem. RHYME AND RHYTHM Duffy does not seem particularly interested in rhyme in this poem, and probably decided before writing it tha ...

  • Cd Recording - 1,974 words
    Cd Recording CD recording has become increasingly popular for a number of reasons. For one, they are extremely cheap. With a mail in rebate it's possible to get them for ten cents a disk. A lot of that is due to the simplicity in design. They're slim. Which means they can be carried easily. A CD can store a vast amount of data. You could put the same information on one CD that it would take hundreds of floppies to hold. CD's can be used in a wide variety of components. You can play them in your car stereo, on your home stereo, on your computer, in your DVD player, or even game consoles. This site was designed to help clear up some of the confusion that has to do with recording CD's. We are g ...

The header, itself contains a pointer, which allows a digital signal level 0 (DS0) structure to be maintained. DS0 are the lines that today transport voice. They are multiplexed together to get larger and larger number of signals through. Signaling with VoATM is compared in the pictures below. VoATM has the ability to either transport voice signals transparently through the network or to interpret and move the signals at ATM speeds. The second is more advantageous because of the use of SVCs or Switched Virtual Circuits. T ...

    Cyber Terrorism The face of global terrorism as we knew it to be 50 odd years ago is changing rapidly with the advancement of technology in todays society. Be it a kid trying to get his kicks bypassing the security or his local Internet Service Provider, or an established terrorist trying to get classified information, the amount of funds we put into protecting ourselves from cyberterrorism is not nearly enough if we were to think about what could be at harm. The vulnerability of commercial systems to cyberattacks is repeatedly demonstrated by events portrayed in the media and, there is no evidence that non-government systems are any more or less vulnerable than government ones, or that the ...

  • Dsl Vs Cable - 1,452 words
    Dsl Vs Cable Cable Modems and ADSL Two modem technologies have emerged over the past year for switched data communications services. Cable Modems operate over two-way hybrid fiber/coax and provide user rates as high as 10 Mbps. ADSL Modems (Asymmetric Digital Subscriber Lines) operate over existing copper telephone lines and provide rates as high as 9 Mbps. Both technologies address the large markets for Internet access, remote LAN access for work at home and telecommuting, and network access for the hundreds of millions of personal computers in place today and to be sold over the next ten years. Cable modems may offer more raw speed than ADSL, but that advantage is compromised by inevitable ...
