问题 填空题

某单位局域网通过ISP提供的宽带线路与Internet相连,ISP分配的公网IP)地址为202.117.12.32/29,局域网中一部分计算机通过代理服务器访问Internet,而另一部分计算机不经过代理服务器直接访问Internet。其网络连接方式及相关的网络参数如图1—2所示。
根据图1—2所给出的网络连接方式及相关的网络参数,区域(A)与区域(B)中计算机的网络参数配置为:
区域(A)计算机“IP地址”(范围): (1)
区域(A)计算机“子网掩码”: (2)
区域(A)计算机“默认网关”: (3)
区域(B)计算机“IP地址”(范围): (4)
区域(B)计算机“子网掩码”: (5)

答案

参考答案:(1)192.168.0.2~192.168.0.254
(2)255.255.255.0
(3)192.168.0.1
(4)202.117.12.35~202.117.12.38
(5)255.255.255.248

解析: 由题目可知,局域网A与代理服务器相连,网关地址为192.168.0.1,子网掩码为24位,因此子网掩码是255.255.255.0,前24位是非主机位,后8位代表主机位,去掉一个网关地址和一个广播地址,局域网A的可用主机地址为192.168.0.2~192.168.0.254。
局域网B网关地址为Modem地址,网络掩码为29位,即2553.255.255.248,把202.117.12.34后8位用点分二进制表示就是202.1 17.12.0010 0010,除去一个网关地址和广播地址,地址范嗣就是202.117.12.0010 0011~202.117.12.00100110,也就是202.117.12.35~202.117.12.38。

Angry Birds is a video game developed by Finnish computer game developer Rovio Mohile. Inspired primarily by a sketch of stylized wingless birds, the game was first released for Apple’s mobile operating system in December 2009.Since then, over 12 million copies of the game have been purchased from Apple’s App Store.

With its fast-growing popularity worldwide, the game and its characters---angry birds and their enemy pigs---have appeared in television programs throughout the world. The Israeli comedy A Wonderful Country ,one of the nation’s most popular TV programs, satirized(讽刺) recent failed Israeli-Palestinian peace attempts by featuring the Angry Birds in peace negotiations with the pigs. Clips of the segment (片段)went viral, getting viewers from all around the world. American television hosts Conan O’Brien ,Jon Steward ,and Daniel Tosh have referenced the game in comedy sketches for their programs, Conan, The Daily Show, and Dash. O. Some of the game’s more famous fans include Prime Minister David Cameron of UK, who plays the iPad version of the game, and author Salman Rushdie, who is believed to be “something of a master at Angry Birds.”

Angry Birds and its characters have also been featured in advertisements in different forms. In March 2011,the characters began appearing in a series of advertisements for Microsoft’s Bing search engine. In the same year, Nokin produced an advertisement in Austin, Texas that included the game’s characters on a downtown building for its new mobile phone. Later, a T-Mobile advertisement filmed in Spain included a real-life mock-up(实物模拟)of the game in a city center .Nokin also used the game in Malaysia to promote an attempt to set a world record for the largest number of people playing a single mobile game.

Angry Birds has even inspired works of philosophical analogy(哲学类比).A five-part essay with the title“ Angry Birds Yoga(瑜伽)---How to Eliminate the Green  Pigs in Your Life” was written by Giridhari Dasar in Brazil ,utilizing the characters and game play mechanics to interpret various concepts of yoga philosophy. The piece attracted much media attention for its unique method of philosophical presentation.
