Types of Networks: LAN, WAN, WLAN, MAN, SAN, PAN, EPN & VPN.



there are several different types of computer networks. Computer networks can be characterized by their size as well as their purpose.
The size of a network can be expressed by the geographic area they occupy and the number of computers that are part of the network. Networks can cover anything from a handful of devices within a single room to millions of devices spread across the entire globe.
Some of the different networks based on size are:
  • Personal area network, or PAN
  • Local area network, or LAN
  • Metropolitan area network, or MAN
  • Wide area network, or WAN
One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common types of area networks are:
  • CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network
  • PAN - Personal Area Network
LAN and WAN are the two primary and best-known categories of area networks, while the others have emerged with technology advances.

Other Types of Area Networks

While LAN and WAN are by far the most popular network types mentioned, you may also commonly see references to these others:
  • Wireless Local Area Network - A LAN based on Wi-Fi wireless network technology
  • Metropolitan Area Network - A network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. A MAN is typically owned and operated by a single entity such as a government body or large corporation.
  • Campus Area Network - A network spanning multiple LANs but smaller than a MAN, such as on a university or local business campus.
  • Storage Area Network - Connects servers to data storage devices through a technology like Fibre Channel.
  • System Area Network (also known as Cluster Area Network) - Links high-performance computers with high-speed connections in a cluster configuration.

WHY IS LISP NOT MORE POPULAR?

Image
LISP is a risky choice  for senior management. If things go wrong, no one is going to blame management for picking a popular object oriented language backed by a major corporation like Oracle or Microsoft. Its much easier to hire programmers with experience in popular, easy to learn languages. Even progressive companies willing to use a more powerful language usually don't choose LISP. This is because many of the newer languages try and compromise by borrowing powerful features from LISP, while staying easy to learn for the masses. Scala and Ruby follow this model. Bad programmers can pick them up quickly and keep writing the same mediocre code that they did in Java. Good programmers can take advantage of the more advanced features to write beautiful code. Parentheses are not the problem.  Haskell is an incredibly powerful and expressive language with a syntax similar to Python or Ruby and it hasn't been widely adopted for many of the same reasons as LISP.
