| 术语 | minicomputer concentrator |
| 释义 | minicomputer concentrator 小型计算机集中器;［小型电脑集中器］ A minicomputer which is used as a remote concentrator and functions as a storage buffer with input/output capabilities. Thus, the concentrator may alter the signalling speed of a message in addition to regulating the flow of messages over the lines. The processing speed of the concentrator is sufficiently rapid that it can accept messages simultaneously from several slow-speed terminals, thus reducing terminal delays caused by waiting for an available circuit to the host processor.Like the front-end processor, a concentrator can be programmed to perform such functions as character-to-message assembly and disassembly, communications line control, message buffering, code conversion, error detection, and automatic answering. 一种用作远程集中器,其操作尤如一个具有输入输出能力的存储缓冲器的小型计算机。除了 调节线路上信息流量以外,集中器还可以改变信号传播速度。集中器的处理速度足够快,可以同时从几个慢速 终端接收信息,因而减少了因为等待通向主机的线路而引起的终端延迟。象前端机一样,也可 以为集中器设计一些程序来完成诸如字符到报文的编汇和拆散、通信线路控制、报文缓冲、代码转换、错误检测及自动应答 等功能。 |
