Compare Web 2.0 and Web 3.0.
Web 2.0 refers to second-generation interactive Internet-based services that enable
people to collaborate, share information, and create new services online. Web 2.0 is
distinguished by technologies and services such as cloud computing, software
mashups and widgets, blogs, RSS, and wikis. These software applications run on the
Web itself instead of the desktop and bring the vision of Web-based computing closer
to realization. Web 2.0 tools and services have fueled the creation of social networks
and other online communities where people can interact with one another in the
manner of their choosing.
Web 3.0 focuses on developing techniques to make searching Web pages more
7-4 What are the principal technologies and standards for wireless networking,
communications, and Internet access?
Define Bluetooth, Wi-Fi, WiMax, and 3G and 4G networks.
Standards for wireless computer networks include Bluetooth (802.15) for small
personal area networks (PANs), Wi-Fi (802.11) for local area networks (LANs), and
WiMax (802.16) for metropolitan area networks (MANs). Bluetooth can link up to
eight devices within a 10-meter area using low-power, radio-based communication
and can transmit up to 722 Kbps in the 2.4 GHz band. Wireless phones, keyboards,
computers, printers, and PDAs using Bluetooth can communicate with one another
and even operate one another without direct user intervention.
Wi-Fi is useful for creating wireless LANs and for providing wireless Internet access.
Its access range is limited to anywhere between 300 feet and three miles. Hotspots are
public access points individuals use to obtain high speed Internet access.

Describe the capabilities of each and for which types of applications each is best
suited.
Bluetooth: Access very limited; useful for creating small personal area
networks.
Wi-Fi: Access is limited to 3050 meters; useful for creating small local area
networks
WiMax: Access is limited to a range up to 31 miles: useful for creating wide
area networks
Define RFID, explain how it works and describe how it provides value to
businesses.

Define WSNs, explain how they work, and describe the kinds of applications that
use them.
Wireless sensor networks (WSNs) are networks of interconnected wireless devices
with some processing and radio-transmitting capability that are embedded into the
physical environment to provide measurements of many points over large spaces.
Wireless sensor networks are valuable for monitoring environmental changes, traffic
patterns, security incidents, or supply chain events. Wireless sensor networks can be

any company to continue to innovate, grow, and expand its reach. (see
Chapter 3) As all three companies try to expand into mobile computing, their
ability to “turn on a dime” in the face of other competitors may be in serious
