A ● 將雙絞線制作成交叉線（一端按ELA/TIA568A線序，另一端按ELA/TIA568B線序），該雙絞線連接的兩個設(shè)備可為__(64)__。(64) ● 以下不屬于中間件技術(shù)的是__(65)__。（65） RMI Applet ● Networks can be interconnected by different devices. In the physical layer，networks can be connected by__(66)__ or hubs，which just move the bits from one network to an identical network. One layer up we find bridges and switches，which operate at data link layer. They can accept__(67)__， examine the MAC address，and forward the frames to a different network while doing minor protocol translation in the process. In the network layer，we have routers that can connect two networks. If two networks have__(68)__network layer， the router may be able to translate between the packet formats. In the transport layer we find transport gateway， which can interface between two transport connections. Finally，in the application layer， application gateways translate message__(69)__. As an example， gateways between Internet and must __(70)__the message and change various header fields.(66) (67) (68) (69) (70) ● The purpose of the requirements definition phase is to produce a clear， plete， consistent， and testable__(71)__of the technical requirements for the software product. During the requirements definition phase，the requirements definition team uses an iterative process to expand a broad statement of the system requirements into a plete and detailed specification of each function that the software must perform and each__(72)__that it must meet. The starting point is usually a set of highlevel requirements from the__(73)__that describe the project or problem. In either case， the requirements definition team formulates an overall concept for the system and then defines__(74)__showing how the system will be operated， publishes the system and operations concept document， and conducts a system concept review(SCR). Following the SCR， the team derives __(75)__ requirements for the system from the high level requirements and the system and 39。operations concept. Using structured or objectoriented analysis the team specifies the software functions and algorithms needed to satisfy ea
