1. In PS/2, a block of physical memory. 
   在ibm的ps／2工作站中，物理存储器的一块（即内存空间的一种单位）。
2. PC servers and workstations 
   pc服务器与工作站
3. In ACF/TCAM, a character string that matches a definition in the key table. This key identifies the destination of a message or special processing to be done on that message. It can also identify a station, logical unit(LU), or application in the network. 
   在ibm的联网通信软件acf／tcam中，一种“与键表中的某一定义相匹配的”字符串，用以标明既定报文的收信方（简称收报方）或对该报文应做何种特殊的处理，也可以标识网络中的工作站、逻辑单元（lu）或应用程序。
4. Novell’s Net ware has become the strongest competitor to IBM's own network operating environment and predates IBM in its support for LANs. In fact，IBM now markets Net ware for both the PC Network and for Token Ring in addition to its own software. The key to Net ware is the file server software and directories on the server are mapped to network drives， thus operating like virtual diskettes from a user's perspective. The server software is a multitasking operating system with a file structure consistent with DOS 2.x and DOS 3.x. The Net ware shell in each workstation intercepts 21H DOS calls and redirects appropriate calls to the server. Perhaps the primary advantage of Net ware is that it runs on a wide variety of networking hardware. Regardless of whether you choose an IBM network， Corvus OMNINET，AT＆T Star LAN，etc. 
   novell公司的netware操作系统已经成为ibm公司特有的网络操作环境最强有力的竞争对手，它在对局域网络的支持方面也早于ibm公司。事实上，除了自己的一部分软件外，ibm公司也为所有的pc网和令牌环网购买了netware操作系统。netware操作系统的最主要部分是文件服务器软件，服务器上的目录被映射到网络驱动器，这样在用户看来，它运行起来就如同是虚拟磁盘。它的服务器软件是一个多任务的操作系统，文件结构也与dos2.x和dos3.x的文件结构一致。工作站上的netware外壳程序拦截了dos的21h中断，并重新走向为对服务器的调用。
5. IBM made a significant breakthrough in August when physicists at its Thomas J.
