Networks
One way to categorize the different
types of computer network designs
is by their scope or scale.
History of Networks Designs
For historical reasons the
networking industry refers to nearly
every type of design as some kind of
area network.
Common Types of Networks
◦ LAN - Local Area Network
◦ WLAN - Wireless Local Area Network
◦ WAN - Wide Area Network
◦ MAN - Metropolitan Area Network
◦ SAN - Storage Area Network, System Area
Network, Server Area Network, or
sometimes Small Area Network
Common Types of Networks
◦ CAN - Campus Area Network, Controller
Area Network, or sometimes Cluster Area
Network
◦ PAN - Personal Area Network
◦ DAN - Desk Area Network
Fact
LAN and WAN were the original
categories of area networks,
Note that these network types are a
separate concept
LAN - Local Area Network
A LAN connects network devices over a
relatively short distance.
Contin.
In addition to operating in a limited space,
LANs are also typically owned, controlled,
and managed by a single person or
organization.
They also tend to use certain connectivity
technologies, primarily Ethernet and
Token Ring.
WAN - Wide Area Network
A WAN spans a large physical distance.
The Internet is the largest WAN, spanning
the Earth.
MAN- Metropolitan Area Network
A metropolitan area network (MAN) is a
network that interconnects users with
computer resources in a geographic area
Contin.
The term is applied to the
interconnection of networks in a city into
a single larger network
Examples of metropolitan area networks
of various sizes can be found in the
metropolitan areas of London, England;
Lodz, Poland; and Geneva, Switzerland.
SAN- Storage Area Network
A storage area network (SAN) is a high-
speed special-purpose network that
interconnects different kinds of data
Typically, a storage area network is part of
the overall network of computing
resources for an enterprise.
