BIS CHAPTER 7

A local area network (LAN) spans a large geographic area such as a state, province, or country.

The Ironman Triathlon World Championship now uses WiMAX technology, which includes cameras strategically placed along the course for spectators, fans, and family to watch the athlete's performance.

Network convergence is the integration of communication channels into a single service.

A domain name system (DNS) converts IP addresses into domains, or identifying labels that use a variety of recognizable naming conventions.

An intranet is a restricted network that relies on Internet technologies to provide an Internet-like environment within the company for information sharing, communications, collaboration, Web publishing, and the support of business processes.

VPNs are often used to connect to a corporate server. VPN stands for a Valued Partner Network.

The three main benefits of networks or a connected world include sharing resources, providing opportunities, and reducing travel.

The main challenges facing networks include security, social, ethical and political issues

Two methods for encrypting network traffic on the Web are secure sockets layer and secure hypertext transfer protocol.

Secure sockets layer (SSL) is a combination of HTTP and SSL to provide encryption and secure identification of an Internet server.

Some of the social challenges with networking occur with newsgroups or blogs where like-minded people can exchange messages. Problems can arise when sensitive social issues become the topic of discussion such as politics or religion.

Mobile and wireless networks are identical and the terms can be used synonymously.

Wireless networking includes personal area networks (PAN) that provide communication over a short distance that is intended for use with devices that are owned and operated by a single user.

A wireless LAN (WLAN) is a means by which portable devices can connect wirelessly to a local area network, using access points that send and receive data via radio waves.

Worldwide Interoperability for Microwave Access (WiMAX) is a communications technology aimed at providing high-speed wireless data over metropolitan area networks.

Radio-frequency identification (RFID) uses electronic tags and labels to identify objects wirelessly over short distances.

RFID innovations and technologies are being used in many industries including retail, hospitals, pharmaceuticals, and ranchers.

A global positioning system (GPS) consists of hardware, software, and data that provide location information for display on a multidimensional map.

A great GIS example, Google earth, combines satellite imagery, geographic data, and Google's search capabilities to create a virtual globe that users can download to a computer or mobile device.

GPS utilizes location-based services (LBS), applications that use location information to provide a service, whereas a GIS does not use LBS applications.

Wireless networks offer many business advantages but can often slow employee productivity and workflow processes.

Enhancing mobility is one of the greatest advantages provided by wireless networks. It allows activities that were formerly tied to physical locations to be performed almost anywhere.

Instant access to customer profiles, account history, and current order status significantly improves the quality of interactions with customers, suppliers, and business partners.

Wireless technology offers the opportunity to redesign and often complicates the work flow processes to be faster, yet more expensive, and more time-consuming

One of the main challenges of business mobility is protecting against theft.

WLANs that use Wi-Fi have a built-in security mechanism called Wi-Fi protected access (WPA), a wireless security protocol to protect Wi-Fi networks.

LBS differ from RFID in that an LBS cannot track and monitor objects such as inventory

With the power of a wireless network, business professionals can take advantage of mobility allowing them to work from anywhere, at any time, using many different devices.
