The
purpose of this target indicator is to deepen the
student's understanding of what comprises a LAN. It is
crucial that students attain understandings of acronyms --
so they must immediately recognize LAN as the acronym for
Local Area Network. But it is also crucial that they not
only know the acronyms (of which there are thousands
within networking), but that they understand the concept
behind the acronym, for example, able to list some
characteristics of LANs. |

One early solution to
these problems was the creation of local area networks (LANs). Because
they could connect all of the workstations, peripherals, terminals,
and other devices in a single building, LANs made it possible for
businesses using computer technology to efficiently share such things
as files and printers.
Local area networks (LANs) consist of computers, network interface
cards, networking media, network traffic control devices, and
peripheral devices. LANs make it possible for businesses that use
computer technology to share, efficiently, such items as files and
printers, and to make possible communications such as e-mail. They tie
together: data, communications, computing, and file servers.
LANs are designed to do the following:
- operate within a limited geographic area
- allow many users to access high-bandwidth media
- provide full-time connectivity to local services
- connect physically adjacent devices
There are many online resources for gaining the most recent
information on LANs. Take a moment to browse some of these sites.
