Network Topologies/Common Network Types Flashcards
1
Q
Logical Network Maps
A
- Specialized software
- Visio, OmniGraffle, Gliffy.com
- High level views
- WAN layout, application flows
• Useful for planning and collaboration
2
Q
Physical network maps
A
- Follows the physical wire and device
* Can include physical rack locations
3
Q
Wireless topologies
A
- Ad hoc networking
- No pre-existing infrastructure
- Devices communication amongst themselves
- Infrastructure
- All devices communicate through an access point
- The most common wireless communication mode
• Mesh
• Ad hoc devices work together to form a mesh
“cloud”
• Self form and self heal
4
Q
LAN - Local Area Network
A
- A building or group of buildings
- High-speed connectivity
- Ethernet and 802.11 wireless
- Any slower and it isn’t “local”
5
Q
WLAN - Wireless LAN
A
- 802.11 technologies
- Mobility within a building or geographic area
- Expand coverage with additional access points
6
Q
MAN - Metropolitan Area Network
A
- A network in your city
- Larger than a LAN, often smaller than a WAN
- Common to see government ownership
- They “own” the right-of-way
7
Q
WAN - Wide Area Network
A
- Generally connects LANs across a distance
- And generally much slower than the LAN
- Many different WAN technologies
- Point-to-point serial, MPLS, etc.
- Terrestrial and non-terrestrial
8
Q
CAN - Campus Area Network
A
- Corporate Area Network
- Limited geographical area
- A group of buildings
- LAN technologies
- Fiber connected, high speed Ethernet
- Your fiber in the ground
- No third-party provider
9
Q
NAS vs. SAN
A
• Network Attached Storage (NAS)
• Connect to a shared storage device across the
network
• File-level access
- Storage Area Network (SAN)
- Looks and feels like a local storage device
- Block-level access
- Very efficient reading and writing
• Requires a lot of bandwidth
• May use an isolated network and high-speed
network technologies

Q
PAN - Personal Area Network
A
- Personal Area Network
- Your own private network - Bluetooth, IR, NFC
- Automobile - audio output, integrate with phone
- Mobile phone - wireless headset
- Health - workout telemetry, daily reports
