The traditional way of allocating a single channel,such as a telephone trunk,among multipl

e competing users is to chop up its （） by using one of the multiplexing schemes, such as FDM. If there are N users, the bandwidth is divided into N equal-sized portions,with each user being assigned one portion.Since each user has private frequency （） ,there is now no interference among users.When there is only a small and constant number of users,each of which has a steady stream or heavy load of （）this division is a simple and efficent allocation mechanism.A wireless example is FM radio stations.Each station gets a portion of the FM band and uses it at most of the time to broadcast its signal. However when the number of senders is large and varying or the traffic is （） ,FDM presents some problems.If the spectrum is cut up into N regions and fewer than N users are currently intrested in communicating ,a large piece of valuable spectrum will be wasted.And if more than N users want to communicate ,some of them will be denied （）for lack of bandwidth,even if some of the users who have been assigned a frequency band ever transmit or receive anything.

Prior to the UML, there was no clearleading(66)Ianguage. Users had to choose from among many similar modeling languages with minor differences in overall(67)power. Most of the modeling languages shared a set of commonly accepted concepts that are expressed slightly differently in various languages. This lack of(68)discouraged new users from entering the OO market and from doing OO modeling, without greatly expanding the power of modeling. Users longed for the industry to adopt one, or a very few, broadly supported modeling languages suitable for(69)usage.

Some Vendors were discouraged from entering the OO modeling area because of the need to support many similar, but slightly different, modeling languages. In particular, the supply of add-on tools has been depressed because small vendors cannot afford to support many different formats from many differem(70)modeling tools. It is important to the entire OO industry to encourage broadly based tools and vendors, as well as niche products that cater to the needs of specialized groups.

Even though current technologies make the ultimate segmented network impractical, new tech

nologies and products hold the promise of making the concept a reality. Most important of all these new technologies are (66) . The ultimate switched LAN, which is technically possible, now, exhibits the following characteristics:

1. High-speed yet cost-effective switching devices can be implemented on a wide scale, providing dedicated connections for individual users and supporting the aggregate (67) of all networked users.

2. The ability to deploy switching capabilities incrementally into the (68) base. Switching implementations support switching of individual users or groups so that existing users of shared media modules can continue to use the existing equipment until they can justify moving to dedicate switched LAN connections.

3. Support and enhancement of existing routed environments. Switching (69) routint, but rather can be introduced into the network without making any changes to the existing routing equipment or configuration.(70) play a critical role in the integration of switching into existing networks.

In one form. of pharming attack, code sent in an E-mail modifies local host files on a personal computer. The host files convert URLs into the number strings that the computer uses to access Web sites. A computer with a compromised host file will go to the fake Web site even if a user types in the correct Internet address or clicks on an affected(74)entry. Some spyware removal programs can correct the corruption, but it frequently recurs unless the user changes browsing(75).
