• Local area networks.

2
What is LAN

• A local area network (LAN) is a computer network
  covering a small geographic area, like a home,
  office, or group of buildings.

3
What are the defining characteristics?

• The defining characteristics of LANs, in contrast
  to Wide Area Networks, include much higher data
  transfer rates, smaller geographic range, and
  lack of a need for leased telecommunication
  lines.

4
History?

• In the days before personal computers, a site
  might have just one central computer, with users
  accessing this via computer terminals over simple
  low-speed cabling.

5
When were they first created?

• The first LANs were created in the late 1970s and
  used to create high-speed links between several
  large central computers at one site.
