What are the disadvantages of peer-to-peer networking?
(32) 
VerifiedThe following is a summary of the disadvantages of peer-to-peer networking:
- Network security applies to only a single resource at a time.
- Users might be forced to use as many passwords as there are shared resources.
- Each machine must be backed up to protect all shared data.
- Every time a user accesses a shared resource, performance of the machine where the resource resides is reduced.
- There is no centralized organizational scheme to locate or control access to data.
- Access to a shared resource is unavailable if the machine where the resource resides is turned off or crashes.
- A peer-to-peer network doesn't usually work well with more than 10 users.
The Microsoft .NET computing model uses the Web to deliver applications as well as information and to enable applications on different devices running different operating environments to communicate and share data.

What is a WAN?
(31) VerifiedBecause of their limitations, early LANs were unable to meet the networking requirements of large organizations, especially those that operated in multiple locations. The benefits of networking were so great, however, that technology evolved to accommodate larger, geographically dispersed organizations. As the scope of a network expands to encompass multiple groups of users in multiple locations, LANs can grow into wide area networks (WANs). A WAN is an internetwork that spans distances measured in miles and links two or more separate LANs. WANs use the services of third-party communications providers, such as telephone companies, to carry network traffic from one location to another.
In a(n)____, every user must also act as a network administrator, controlling access to the resources on their machines.
(31) The ____________________, the best example of the largest internetwork in the world, is a vast public wide area internetwork that makes it possible for any computer in the world to communicate with any other computer in the world using standard technologies and protocols.
(27) In the domain model, before users can access resources on the network, they must identify themselves to a(n)____, which is a server that checks account names and passwords against a database of information it maintains.
(25) All nonserver versions of Windows, from Windows 3.11 to Windows Vista, support a special networking model, called the ____________________ model, that permits groups of machines to work together as peers in the absence of a special-purpose server.
(31) A(n)____ is a network of networks or a networked collection of LANs tied together by devices such as routers.
(31) The ____ is a short-range networking technology designed to connect personal devices to exchange information.
(33) To access any network, computers must attach to the network medium by using some kind of physical interface; for PCs, this interface is usually an RS-232 port.
(31) In the Novell world, one or more NetWare servers provide similar controls over users and the resources they can access by using Novell ____ to store and manage the same kind of security information that Windows domain controllers handle.
(30) When should you choose to use a peer-to-peer network instead of a client-server network?
(28) ____ servers supply the server side of client/server applications, and often the data that goes along with them, to network clients.
(30) Windows Server 2000/2003 includes a complete Web server called ____.
