For example, WLAN-based applications can enable fine-grained management of supply and distribution (166) to improve their efficienty and reduce (167) . WLAN

19、s can also enable entirely new business processes. To cite but one example, hospitals are using WLAN-enabled point-of-care applications to reduce errors and improve overall (168) care. WLAN management solutions provide a variety of other benefits that can be substantial but difficult to measure. For

20、 example, they can protect corporate data by preventing (169) through rogue access points. They help control salary costs, by allowing IT staffs to manage larger networks without adding staff. And they can improve overall network mananement by integrating with customers existing systems, such as Ope

21、nView and UniCenter.

23、ions of electronic (161) taking place daily, businesses and organizations have a strong incentive to protect the (162) of the data exchanged in this manner, and to positively ensure the (163) of those involved in the transactions. This has led to an industry-wide quest for better, more secure method

24、s for controlling IT operations, and for deploying strong security mechanisms deeply and broadly throughout networked infrastructures and client devices. One of the more successful concepts to engage the imaginations of the security community has been the development of standards-based security (164

25、 ) that can be incorporated in the hardware design of client computers.

This lack of (113) 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 s

29、upported modeling languages suitable for (114) 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 aff

30、ord to support many different formats from many different (115) modeling tools. It is important to the entire O0 industry to encourage broadly based tools and vendors, as well as niche products that cater to the needs of specialized groups.（分数：5.00）(1).A. programming B. modelingC. formal D. intellig
