Understanding state Introduction to viewState Using querystrings Using sessions Using cookies Managing state Developing an application on the Internet presents some special challenges. One of the major obstacles is persisting state throughout the application. This chapter discusses how, in the disconnected world of the Internet, it is possible to maintain state between pages as the user clicks through your applications.

Modern cellular handsets are anticipated to be able to handle different frequencies for communications. As discussed in Section 9.2.2 a GSM handset, e.g., needs to be able to deal at least with 900 and 1,800 MHz foreseen in the speci cations for most countries. As an added dif culty, many

Most modern wireless networks conform to a set of standards that ensures that hardware from different brands will work with each other. You ve probably heard of IEEE 802.11b, 802.11g, or maybe 802.11n. You may also have heard of and/or seen the label Wi-Fi. Here s what that stuff means. IEEE stands for Institute of Electrical and Electronic Engineers. This international group creates and ratifies sets of standards for everything from wireless networking to how batteries are made. Without such standards, hardware producers could make any hardware however they pleased, without bothering to ensure that it worked with other hardware. For example, the IEEE 1394 standard defines how FireWire works. Any IEEE 1394 compliant device, such as a camcorder, should work with any IEEE 1394 compliant port on a computer. Standards of this nature greatly simplify things for end-users like you and me.
