Since the bulk of the database processing is done on the back-end, the speed of the DBMS isn’t tied to the speed of the _A_. The major disadvantage of Client/Server system is the increased cost of _B_ and support personnel Who maintain the database server. There is also the issue of C with so many parts comprising the entire C/S system, Murphy’s Law can kick in-the more pieces that compose the system, the more pieces that can fail. It’s also harder to track down problems when the system _D_. And it can initially take longer to get all the components set up and working together. All this is compounded by the general lack of experience and expertise of potential support personnel and programmers, due to the relative newness of the technology. As C/S system become more common, this problem should abate. Therefore the C/S system is more _E_. A： ①network ②operating system ③personal computer ④workstation B： ①administrative ②bureaucratic ③manager ④official C： ①complexity ②possibility ③simplicity ④variety D： ①burns ②crashes ③runs ④uses E： ①efficient and easy to setup ②efficient and robust ③efficient but difficult to maintain ④robust but difficult to setup

CTI has actually been around for a good two decades. Until recently, it required users to _A_ a good deal of knowledge about telephone interconnect processes as well as networking and database programming to _B_ even the most rudimentary tasks. These two skill sets are rarely possessed by the same individual. But today CTI has gone client/server. Microsoft corp. Has included its client-side Telephony API (TAPI) with every copy of windows 95. The company’s service-side TAPI is now available for Windows NT. There are many telephony _C_ that turn the interconnect portion of a CTI _D_ into standard data programming, and low-cost, easy –to- create telephony is born. Better yet, many of these _C_ are Visual Basic add-ons. CTI is also subject to all the cost benefits of cheaper, PC-based hardware. The two portions of CTI are _E_. A、B：①acquire ②capture ③modify ④perform ⑤possess ⑥process C、D：①goodness ②item ③object ④packages ⑤proceeding ⑥project ⑦software ⑧subject ⑨toolkits ⑩utilizations E：①interconnection and Telephony toolkits ②interconnection and Visual Basic all-ones ③interconnection and programming ④networking and database programming
