Flashcards in LANs And WANs Deck (18):

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


what are the two general types of networks you can have

- a client-server network
- or a peer-to-peer network


what is a client server network

- a network which has a central server
- where all information travels through to reach other nodes


what is a peer to peer network

- a network where all devices have equal standing
- and there is no permanent server processing requests
- but instead all devices could act as the client depending on the request
