英语翻译
Home area network
A home area network is a residential LAN which is used
for communication between digital devices typically deployed in the home,
usually a small number of personal computers and accessories,such as printers
and mobile computing devices.An important function is the sharing of Internet
access,often a broadband service through a CATV or Digital Subscriber Line
(DSL) provider.
Campus network
A campus network is a computer network
made up of an interconnection of local area networks (LANs) within a limited geographical area.The networking equipments (switches,routers) and transmission media (optical fiber,copper plant,cat 5 cabling,etc.) are almost entirely owned (by the campus tenant/ owner:an enterprise,university,government,etc.).
In the case of a university campus-based campus network,the network is likely to link a variety of campus buildings including academic departments,the university library and student residence halls.
Wide area network
A wide area network (WAN) is a computer network that covers a large
geographic area such as a city,country,or spans even intercontinental
distances,using a communications channel that combines many types of media
such as telephone lines ,cables,and air waves.A WAN often uses transmission
facilities provided by common carries,such as telephone companies.WAN
technologies generally function at the lower three layers of the OSI reference
model:the physical layer,the data link layer,and the network layer.
Global area network
A global area network (GAN) is a network used for supporting mobile communications across an arbitrary number of wireless LANS,satellite coverage areas,etc.The key challenge in mobile communications is handing off the user communications from one local coverage area to the next.In IEEE Project 802,this involves a succession of the terrestrial WIRELESS local area networks (WLAN).

家庭区域网络
一个家庭网络是一个住宅局域网
数字设备之间的通信通常部署在家里,
通常是一个小的个人电脑和配件,如打印机
和移动计算设备.一个重要的功能是共享上网
访问,往往是通过CATV或数字用户线路的宽带服务
（DSL）供应商.
校园网络
一个校园网的计算机网络
由在一个有限的地理区域之内的局部区域网络（LAN）的互连.几乎全资拥有的网络设备（交换机,路由器）和传输介质（光纤,铜线厂,CAT 5电缆等）（校园租户/业主：一个企业,大学,政府等）.
在一所大学校园为基础的校园网络的情况下,网络很可能连接一个校园建筑,包括各种学术部门,大学图书馆和学生宿舍.
广域网
一个广域网（WAN）是一个计算机网络,覆盖了大
甚至洲际的地理区域,如城市,国家,或跨越
的距离,使用一个通信信道,结合多种类型的媒体
如电话线,电缆和空气波.一个广域网经常使用传输
共同的运载,如电话公司所提供的设施.广域网
技术一般可在较低的三个层的OSI参考
型号：物理层,数据链路层和网络层.
全球区域网络
一个全球区域网络（GAN）,用于支持任意数量的无线局域网,卫星覆盖区域等移动通信的主要挑战是处理从一个本地的覆盖范围内的用户通信的下一个移动通信的网络.在IEEE项目802,这涉及到一个连续的地面无线局域网（WLAN）
