Networked Devices
• Networked devices are devices that communicate with a
network.
• Technologies include laptops, PDAs, cell and
smartphones, wikis, intranets, and extranets, GPSs, POS
terminals, and RFID which allow information to be rapidly
collected, processed, shared, and acted upon for
competitive survival and advantage taking.
• Feature-rich wireless devices make collaboration easier
and more productive which indicates a more integrated,
always-connected business environment and lifestyle.

Social Networking Shrinks the World
• Social networking via mobile phones is shrinking the
world to the size of a small screen.
• Micro-blogging is the sending of messages up to 140
characters.
• With more than 3 billion mobile handsets in use in the
world (1 for every 2 people on the planet) a powerful force
for changes in business and collaboration as well as
politics and societies have emerged.
• News media, universities, public safety, and other
organizations are using the technology to deliver
information to a wide audience quickly.

Business networks support basic functions:
1.
Communication : Being able to talk, text, tweet, fax, send messages, etc.
2.
Mobility
 Having secure, trusted, and reliable access from anywhere at
satisfactory download (DL) and upload (UL) speeds.
3.
Collaboration
 Supporting teamwork activities that are synchronous and asynchronous;
brain storming; and knowledge and document sharing with in the
organization and with outside business partners and interests.
4.
Relationships
 Managing interaction with customers, supply chain partners,
shareholders, employees, regulatory agencies, etc.
5.
Search
 Locating data, contracts, documents, spreadsheets, diagrams,
messages, and other knowledge within an organization easily and
efficiently

Network Terminology
• Bandwidth: Throughput capacity or speed of a network.
• Protocol: Standards that govern how networked devices
exchange information.
• TCP/IP: Transmission control protocol/Internet Protocol) are
a suite of Internet protocols.
• Broadband: Short for broad bandwidth.
– Fixed-line broadband: Cable or DSL Internet connections.
– Mobile broadband: Wireless high-speed Internet access through a
portable modem, phone, or other device.

4.2 Wireless Broadband Networks
• Enterprises are moving away from unsystematic
adoption of mobile devices and infrastructure to a
strategic build-out of mobile capabilities.
• Mobile infrastructure consists of technology,
software, support, security measures, and devices to
manage and deliver wireless communications.

4.3 Networks Management and Portals
• When the network goes down or access is blocked, so
does the ability to operate or function.
• Damages when a company cannot operate or fulfill orders
include:
– lost sales and productivity
– Inability to send and receive payments
– inability to process payroll and inventory

TCP/IP Networks
• The Internet protocol suite consists of the IP (Internet
Protocol) and TCP (Transport Control Protocol), or TCP/IP.

packets and sent via packet-switched networks, local
area networks (LAN), or wide area networks (WAN).

Network Computing Infrastructures
• Intranets: a network serving the internal
informational needs of a company.
• Extranets: private, company-owned network that uses
IP technology to securely share part of a business’s
information or operations with suppliers, vendors,
partners, customers, or other businesses.
• Extranets can use virtual private networks (VPNs). VPNs
are created using specialized software and hardware to
encrypt/send/decrypt transmissions over the
Internet.

Wild About Wikis
By Rachael King
• Intel, Motorola, Sony—they're among the companies
using Web-collaboration tools to promote products
and foster teamwork among employees
4-25
Wikis are Web-based tools that make it easy for users to
add, remove, and change online content. Employees at
companies such as Intel, Motorola, IBM, and Sony use
them for a host of tasks, from setting internal meeting
agendas to posting documents related to new products.
4-26
Many companies rely on wikis to engage customers in
ongoing discussions about products. Wikis for Motorola and
T-Mobile handsets serve as continually updated user
guides. TV networks including ABC and CBS are creating
fan wikis that let viewers interact with each other as they
unravel mysteries from such shows as Lost and CSI: Crime
Scene Investigation. Read about these and other ways
companies are warming to wikis. A link is included where
the wiki is open to the public.

• In the U.S., Verizon Wireless is developing a suite of digital
health care solutions that include chronic care management
and virtual care.
• Its digital care management solution will leverage a cloud platform and
connected medical devices. This solution will integrate biometric
devices and deliver personalized care plans to people on their mobile
devices.
• The virtual care solution will leverage advances in 4G LTE technology
by utilizing smartphones, tablets, and video technology.
• Mobile and Virtual Care. The resulting tool will virtualize a health care
visit, eliminating the need to physically visit a doctor’s office for many
routine consults.
