Networks Flashcards
IoT
Internet of Things
Just about everything wants to join your network
Converged Network
Network transporting multiple types of traffic (voice, video, data)
Client
Device end user uses to access network
Server
Serves resources to a network
Hub
Obsolete technology that interconnects network components
Layer 1 device
Switch
Interconnects network components.
Layer 2 device
Routing decisions based on MAC
Router
Forwarding decisions based on IP address
Layer 3 device
Media
Interconnects network devices.
Copper, fiber, radio waves, etc.
WAN link
Interconnects two locations via a MPLS network
MPLS
Multiprotocol Label Switching
LAN
Local Area Network
Interconnects network components within a local area (building)
WAN
Wide Area Network
Interconnects network components that are geographically separated
e.g. MPLS, ATM
IEEE
Institute of Electrical and Electronics Engineers
ATM
Asynchronous Transfer Mode
WLAN
Wireless Local Area Network
SAN
Storage Area Network
CAN
Campus Area Network
Interconnected buildings
MAN
Metropolitan Area Network
Interconnects locations scattered throughout a city
More widespread than CAN, less than WAN
e.g. Metro Internet
PAN
Personal Area Network
Range limited to a few meters
Client/Server Networks
Used by businesses
Better performance and more expensive than peer-to-peer
Peer-to-Peer Networks
Interconnected devices share resources with each other
Used in homes and smaller businesses
Not very scalable
