Introduction To Networks Flashcards
What is a mesh topology
Mesh networks are when every workstation is connected to every other workstation.
What are the pro’s of a mesh topology
Redundancy. Usually used to link back ups to each other. And fast switching.
What are the cons of mesh topology
Expensive and difficult to maintain because of the amount of connections.
What is a hybrid topology
When multiple architectures are used. Star + mesh. Or mesh+ ring.
What is a star topology
When devices are linked to a central hub. Most common in small offices.
Pros of star/hub and spoke architecture?
Easy to trouble shoot.
What is a LAN
local area network. Connects devices on the same network.
What is a WAN
Wide area network. Connects different LANs together by the use of routers.
What is a Workstation
A powerful computer used to link users to the network. Different from client machine.
What is a Server?
A powerful computer used to run a specific task. Email server, web server, print server.
What is a host?
Any device connected to a network.
What is a MAN?
Metropolitan Area Network. A network covering a metropolitan area connecting different buildings usually with the use of a carrier provider.
What is a PAN?
Personal Area Network. Smart watch connected to a laptop connected to a smart phone. Using Bluetooth or Zigbee.
What is a CAN?
Campus Area Network. Typically connects LANs in various buildings via WiFi.
What is a SAN
Storage Area Network. Designed for storing and distributing stored data.
What is FCoE
Fibre Channel over Ethernet. A connection you see in SANs
What is iSCSI (iscuzy)?
A next gen protocol used in SANs used to transport data.
What is a SDWAN?
Software defined wide area network. Uses MPLS, LTE and broadcast internet services to connect users to applications.
What is MPLS?
Multiprotocol Label Switching. Is a switching mechanism that imposes labels to data and the. Uses those labels to forward data. Cloud switching.
What is mGRE?
Multipoint Generic Routing Encapsulation. A protocol that refers to a carrier or service provider that dynamically creates and terminates connections to nodes on a network.
What is a peer to peer network?
There is no central authority. Think PAN.
What are pros of peer to peer?
Works when there aren’t a lot of users.
Everyone is responsible for their own backups.
Cons of peer to peer?
No centralized source of formations so backups can be hard.
Hard to locate vital documents.
What is a client server network?
One computer stores and handles distribution of the data it has been assigned to distribute.
What is ring topology?
When every computer is directly connected to the next in the same network. Like a ring. WAN providers use this.
What is point to point Topology
When you have a direct connection between two routers or switches. Key is this defines the connection between routers.
What is point to multipoint topology?
When a master router connects to multiple destination routers.
What is a network segment
A division of workstations or devices on the network.
What is Service-Related Entry Points
The connections installed by ISP(internet service providers) to connect to the internet.
What are Service Provider Links?
The type of connection a service provider supplies. Ex. DSL cables, satellite, hybrid fiber
What is a vSwitch?
A Virtual Switch used to connect different hypervisors together.
What is a nNIC
Used to connect a virtual machine to the host computers Network Interface Card.
What is NFV
Network function virtualization.
What is the purpose of the core layer?
To connect distribution layers together.
