LANs And WANs Flashcards
what are stand alone computers
computers that are not connected to any other computer or network
what is the world currently crossed with which makes it global
- interconnected networks around the world
- with different types of networks existing within them
can one computer belong to multiple types of networks and what are some examples if they can
- they can
- such as having a LAN network in your house but being connected to the internet, a global network
what is the type of network determined by
its size
what are actually the three different types of networks that exist
- LANs
- WANs
- PANs
what is a LAN
- a network over a small geographical area
- usually occupying a single building
why might schools or offices have a network such as a LAN
- they might have a number of computers that need to access the internet, send emails to each other or share printers
- in other words, for connectivity
which type of network would the organisation that owns the building usually own the network hardware for it
a LAN network
what is a WAN
- a network over a large geographical area
- much larger than a LAN
- can span across countries or continents
what is the largest WAN in the world currently
the internet
what does a WAN typically connect
2 or more LANs
what is an example of a WAN connecting two or more LANs
- a company might have an office in london and new york
- each office building would have its own LAN network
- but the two combined with a connection between them creates a WAN network
who would own a WAN network despite the organisation of the building owning the LAN hardware
- a communication provider would own the WAN
- which would usually be shared among other WANs, also transmitting between WANs
what is a PAN
- a personal area network
- which describes the interconnected devices used by a single person
how could someone form a PAN
- if their devices could communicate with one another directly
- without requiring access to the internet
- such as a phone, laptop, printer and console
