In recent years, one of the more popular topics for panel discussions at computer conferences and trade(1)has been the "RISC versus CISC" debate.
RISC processors feature a small number of instructions that each executes in(2)machine cycle. CISC processors use complex instructions that can take several cycles to execute.
The RISC versus CISC debate won't be decided by panel discussion; it will be won in the marketplace. And the deciding factor may have little to do with the(3)ofinstructions and registers and more to do with parallelism.
Since their conception, RISC processors have been evolving toward microparallelism. Incorporating parallel-processing features(4)the processor, RISC processors feature pipelining, whereby many instructions can be decoded while one instruction executes. RISC processors, however, are moving toward pipelines for each unit of the processor.
CISC processors also employ pipelining. They have many integer instructions that execute in one cycle, but the varying execution times of CISC instructions(5)the effectiveness of parallelism.

Object-oriented DBMS integrated a variety of(1)data types—such as business procedures, graphics, pictures, voice and annotated text.
Object orientation also makes a(2)to application development efficiency. It makes the data, functions, attributes and relationships an integral part of the(3). In this way, objects can be reused and replicated.
Some leading RDBMS vendors support the concept of integrating object management capabilities with their current line of relational products. That capability enable users to(4)the development cycle, since integrity logic and business rules no longer need to be programmed(5)each application.

An expert system is a software that(1)specialist knowledge about a particular domain of(2)and is capable of making(3)decisions within that domain. Although expert systems typically focus on a very narrow domain, they have achieved dramatic success with(4)problems. This has excited widespread interest outside the research laboratories from which they emerged.
Expert systems have given rise to set of "knowledge engineering" methods constituting a new approach to design of high performance software system. This new approach represents an(5)change with revolutionary consequences.

It is traditional when dealing with languages of all sorts to try to separate concerns with(1), the subject of syntax, from concerns with(2), the field of semantics. Consider the simple "language" of binary numerals. Some examples of binary numerals are
1
101 101
11001 101111
A communication in this language evidently consists of afinite sequence of characters “0”、“1". This is just syntax however, and says(3)about what such a communication is intended to mean.
Numbers are"(4)" mathematical concepts, whereas the digit strings that appear on paper are numerals, that is to say,(5)representations or descriptions of numbers.

In(1)software, one question of near-universal interest is how rapidly Windows NT, which began shipping last summer, will be(2)in the marketplace and for what uses. For the most part, observers are(3)the operating system's long term prospects, but expect it to remain on(4)rather than desktops during 1994, saying that it won't become a mainstream product until(5)PCs typically have 16 to 24 MB of RAM, which is unlikely to happen next year.
