1.5 Flashcards
What is a physical network map?
A map that follows the physical wire and device. It also include the same in a rack.
What is a logical network map?
Specialized software useful for planning and collaboration to be used in high level views.
What is a Star topology?
It’s a topology used in most large and small networks where all devices are connected to a central device like a switch.
What is a RIng topology?
It’s a topology still used in many MANs and WANs where all of the devices are connected to each other like a ring form.
What is a Mesh network?
Its a topology where there are multiple links to the same place for redundancy, fault-tolerance and load balancing. Mostly used in WANs.
What is a Bus network?
It’s atopology used in local area networks which is simple but prone to errors and mostly used in a vehicle CAN bus (Controller Area Network).
What are some wireless logical topologies?
- Infrastructure
- Ad hoc networking
- Mesh
What is the most common wireless communication mode?
Infrastructure (all devices communicate through an access point)
What is Ad hoc networking?
It’s a wireless logical topology where device communicate amongst themselves without an access point (No pre-existing infrastructure).
What’s a logical Mesh topology?
It’s a network topology where Ad hoc devices work together to form a mesh “cloud”.
Whats the advantage of logical mesh compared to other wireless topologies?
It self forms and self heals.
Whats a LAN?
A network in a building or group of buildings which is high-speed connectivity. (Local Area Network)
What are the types of a LAN?
- Ethernet
2. 802.11 wireless
Whats a WLAN?
It’s the wireless LAN which uses 802.11 technology and you can expand expand coverage with additional access points.
Whats a MAN?
It’s a network in the city which is larger than LAN but smaller than WAN which is common to see them in government ownerships (Metropolitan Area Network)
Whats a WAN?
A network that is spanning the globe and usually connects LANs across a distance but generally slower than LANs. (Wide Area Network)
What are some examples of WAN technologies?
- Point-to-point serial
- MPLS
- Satellite communications
What is a CAN?
(Campus Area Network) It’s a limited geographic area network using LAN technologies to create a network within a few building close to each other.
What technology does a CAN use?
LAN technologies like a fiber connected or high speed Ethernet but there is no need for a third party provider.
What is a NAS?
(Network Attached Storage) Its a network connected to a shared storage device across the network, also called File-level access.
What is a SAN?
(Storage Area Network) It’s a network that looks and feels like a local storage device but it’s very efficient for reading and writing. Also called Block-level access.
What do NAS and SAN require?
A lot of bandwidth
What is a PAN?
(Personal Area Network) user’s own private network
What are some examples of PAN?
Bluetooth, IR, NFC and they get used in an automobile, mobile phones and health devices like a workout telemetry.
