1、软件设计师-专业英语(五)及答案解析(总分：45.00，做题时间：90 分钟)一、单项选择题(总题数：9，分数：45.00)SOCKS is a genetic proxy protocol for TCP/IP-based networking, applications. SOCKS includes two (21) , the SOCKS server and the SOCKS client. The SOCKS server is implemented at the application layer. The SOCKS client is implemented betwee

2、n applications and the (22) layer. When an application client needs to connect to an application server, the client connects to a SOCKS proxy server. The proxy server connects to the application server instead of the client, and (23) data between the client and the application server. For the applic

3、ation server, the proxy server is the (24) . SOCKS is also one of the popular (25) to network firewalls. Because of its simplicity and flexibility, SOCKS has been used as genetic application proxy in virtual private network (VPN), and for extranet applications.（分数：5.00）(1).A. elements B. components

In the physical layer, networks can be connected by (41) 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 (42) ,

If two networks have (43) network layer, the router may be able to translate between the packet formats.

7、In the transport layer we find transport gateway, which can interface between two transport connections. Finally, in the application layer, application gateways translate message (44) . As an example, gateways between Internet E-mail and X.400 E-mail must (45) the E-mail message and change various h
