ActiveX is the name(66)has given to a set of object-oriented concepts, technologies, and tools. It is important to notice that ActiveX is not a(67)technology, but a brand name, what it's applied to can vary over time. However, the main technology is COM. Used in a network with a(68)and additional support, COM becomes the DCOM. The main object that is created when writing a program to run in the ActiveX environment is a(69), a self-sufficient program that can be run anywher6 in the ActiveX network. This component is known as an "ActiveX control". An ActiveX control is roughly equivalent to a applet. One important difference is that an ActiveX control must be(70)for a specific platform, while an applet is platform-independent.
FDDI中采用(24)编码技术,使编码效率提高到(25),这对于100Mbit/s的光纤网,意味着只需要125MHz元件就可以实现。为了得到足够的同步信息,FDDI实际采用二进制编码方法,即先技(24)编码后,再用(26)。为了消除环网中数据的时钟偏移,FDDI使用了(27),并规定进入站点缓冲器的数据时钟按照输入信号的时钟确定,而从缓冲器输出的时钟信号是根据(28)确定。
