问题 单项选择题

在进行金融业务系统的网络设计时,应该优先考虑 原则。

A.先进性
B.开放性
C.经济性
D.高可用性

答案

参考答案:D

解析:

[分析]:
网络设计一般要遵循如下一些原则。
·先进性:建设一个现代化的网络系统,应尽可能采用先进而成熟的技术,应在一段时间内保证其主流地位。但是太新的技术,也有不足之处,一是有可能不成熟,
二是标准可能还不完备、不统一,三是价格高,四是可能技术支持力量不够。
·开放性:采用国际通用的标准和技术获得良好的开放性,是网络互连互通的基础。
·经济性:在满足需求的基础上,应该尽量节省费用。
·高可用性:系统要有很高的平均无故障时间和尽可能低的平均故障率,一般需要要采取热备份、冗余等技术。
金融系统涉及银行、众多储户的资产信息,数据重要、敏感,数据量庞大,必须要保证数据的绝对安全,同时要保证系统小的响应时间、很高的服务成功率,而且服务要完整、不间断,故障恢复能力强,整个系统要具有非常高的可用性和可靠性,并不追求采用先进的技术。另外,一般金融系统都是封闭运行的,开放性也不需要放在优先考虑的地位。因此在进行有关金融系统的网络设计时,高可用性是首要考虑的原则。

     Guess who is the most successful young writer in China? It is 24-year-old Guo Jingming, who

earned $ 1.4 million last year, according to the Ne.7u York Times.

     Guo started his writing career in high school when he won first prize in a national writing contest

in 2001. His first book, City of Fantasy, came out soon after the contest and went on to sell more than

1. 5 million copies.

    Almost all Guo's novels include a shy hero who gets good grades. He mostly writes about the sad

feelings of his young characters. These teenagers deal with loneliness by sitting alone for long hours

under trees and on rooftops. "Xiaosi(Guo's nickname), I will always be with you!" A reader wrote in

Guo's blog. "My main goal (目标) is to tell the story well and have everyone like it," Guo said.

     In fact, Guo is seen more as an idol than as a writer. His handsome outlooking, cross-dressing and

strange actions make newspapers pay more attention to himself than his books. Many fans are eager to

get his autograph.

    But today he faces what may be more dangerous threat (威胁): even younger writers. The past few

years have seen the rise of a group of teenage writers, sometimes called the "Post-90s" generation.

However Guo seems to have plans to meet them. Next year, he will hold a national competition for

these rivals (对手).
