3a LAN, WAN, Virtual Network * Flashcards
Identify three characteristics of a local area network (LAN).
connected by high speed connections (1)
Within a locally defined area (1)
can have direct connections between machines (1)
connected by cables owned by the company (1)
able to share local peripherals (1)
Identify three characteristics of a wide area network (WAN).
geographically remote (1) external telecommunications/external hardware (1) connected by third party cables (1)
The computers in this second building must still be part of the LAN….describe how the wedding outfitters could use a virtual network within their LAN
two or more of their departments could exist on the LAN (1) but each computer would only communicate with others in the same department (1)
services such as file sharing, printing and application sharing would be the same as on the single LAN (1) but on a virtual network these services could be allocated to just those individuals within a particular department (1)
to offer secure remote access to existing resources (1) as if working locally (1)
to provide a secure extension of their private network (1) into an insecure environment such as the internet for workers (1)
to separate the traffic of different user groups (1) over their
underlying network with strong security features (1) [4]
Give 2 comparisons between a WAN and a LAN
a LAN is connected by high speed connections within the business whereas a WAN uses external telecommunications / external hardware
communication in a LAN is handled by internal hardware such as switches and servers whereas a WAN needs an ISP to connect externally to the internet to enable communication between sites
connectivity
a LAN is connected by cables owned by the business whereas a WAN is connected by third party cables (1)
configuration
a virtual network can be configured to exist across both multiple LANs and a WAN
