that are concerned with data types and logical addressing and the lower OSI layer that is only concerned with physical interfaces and signaling protocols. One of the ways the LLC bridges the layers together is by managing transmission timing and providing the working parts of flow control. The MAC sublayer is responsible for generating the new frames that encapsulate packets from the transport layer. These frames are made up of binary values (1 s and 0 s). This binary format is all the physical layer (layer 1) understands. Besides making one last data change, the MAC layer performs some basic data integrity checks. The cyclical redundancy check (CRC) ensures by means of a complex calculation that data reconstructed out of the bits received from the physical layer is intact. Services at the MAC sublayer control which kind of media access method is used. The media are the physical components of the network such as interfaces and cabling. These MAC sublayer methods determine how these components are controlled. The goal of these methods is to prevent hosts from communicating on top of each other, which causes data loss. Typically, one of three methods is used:

Typically in a wireless environment, the authentication server is a RADIUS server. Microsoft Windows 2000 Server and Microsoft Windows Server 2003 include the Internet Authentication Service, the Microsoft implementation of a RADIUS server. For wireless connections, Windows XP (SP1 or later) can use either the Extensible Authentication Protocol Transport Layer Protocol (EAP-TLS) (defined by RFC 2716) or the Protected EAP-Microsoft Challenge-Handshake Authentication Protocol version 2 (PEAP-MS-CHAP v2).

1. Select the tstbUrl tool strip text box. 2. In the events list in the Properties window for tstbUrl, double-click the KeyUp event. The following is the code to determine whether the user pressed and released the Enter key; it also contains the method NavigateToUrl that lets you use the same code in more than one place. Add this code to tstbUrl_KeyUp, and add the NavigateToUrl method.

Microsoft Windows XP supports both infrastructure mode and ad hoc mode wireless network configurations. An infrastructure mode wireless network uses a dedicated device to enable access to the network, either an access point or a router (often called a gateway). An ad hoc mode wireless network is the network used between two wireless clients, such as a pair of Windows XP machines. By default, Windows XP will use either infrastructure mode or ad hoc mode, but it will prefer infrastructure mode.

G Contention-based media access. This method requires that any host want-

In an infrastructure mode wireless network, an access point acts as a network bridge between the wired and wireless segments of the local area network (LAN), as shown in Figure 21-1.

ing to transmit must have control over the network segment to which it is connected. Each communicating host contends for control of the segment. It is possible for more than one host on a network to transmit at a time (under certain conditions). When this happens, the data from two transmitting computers collides, and the net result is data loss. This method is used in a common type of network called Ethernet.

Part III:

In an infrastructure mode wireless network that uses a wireless gateway, as shown in Figure 21-2, there are generally several wired ports and a wireless access point combined on one segment that is then routed out a wide area network (WAN) port to connect either to the rest of the network or to the Internet.

called a token. The token is passed from one computer to another in a round robin fashion. Any computer can transmit if it has possession of the token, and there is no data attached to the token. Once the host decides to transmit, the data is added to the token frame and forwarded to the next host. When the targeted recipient receives the token, it pulls the data off, and then forwards the empty token back into the ring. This method ensures that only one host transmits at a time, and data collisions are not possible.
