ITM Chapter 12
Telecommunication system—enables the transmission of data over public or
private networks.
Network—a system created by linking two or more computers and establishing
standards, or protocols, so that they can work together.
•The three types of networks include:
−Local area network (LAN)
−Metropolitan area network (MAN)
−Wide area network (WAN)
The key advantage of providing data communication links between a company and
its suppliers or customers is the sharing of data.
Data communication links enable data sharing allowing companies to be
competitive.
Voice over IP (VoIP)—uses TCP/IP technology to transmit voice calls over long-
distance telephone lines.
Virtual private network (VPN)—a way to use the public telecommunication
infrastructure (e.g., Internet) to provide secure access to an organization’s network
Valued-added network (VAN)—a private network, provided by a third party, for
exchanging information through a high capacity, secure connection.
Mobile technology—means the technology can travel with the user, but it is not
necessarily in real-time.
Wireless technology—gives users a live (Internet) connection via satellite or radio
transmitters. The signal is carried on radio waves, microwaves and satellites.
Wireless technology—refers to any type of electrical or electronic operation that is
accomplished without the use of a “hard wired” connection.
Mobile Applications can:
Help track materials and shipments from suppliers and distributors to
customers.
Manage inventory.
Support Point of Sale.
Collect data in an automated fashion.
Immediate data analysis.
Personal digital assistants (PDA)—are small, handheld computers capable of
entirely digital communications transmission.
Smartphone—combines the functions of a cellular phone and a PDA in a single
device.

Data communication links enable data sharing allowing companies to be competitive. Voice over ip (voip) uses tcp/ip technology to transmit voice calls over long- distance telephone lines. Virtual private network (vpn) a way to use the public telecommunication infrastructure (e. g. , internet) to provide secure access to an organization"s network. Valued-added network (van) a private network, provided by a third party, for exchanging information through a high capacity, secure connection.
