1.2.1 - Network Types Flashcards
What is a “Peer-to-Peer” network type? What is the advantages/disadvantages?
A P2P network type is where all devices are connected to reach other. Example: computer to computer connection.
Advantage(s): Easy to deploy with a low cost
Disadvantage(s): Difficult to administer and to secure
What is a “Client-to-Server” network type? What are the advantages/disadvantages?
A C2S network type is a computer or series of computers connected to a single server. Thus communicating with the server but no C2C (P2P) comms.
Advantages: Performance and administration
Disadvantages: Cost, complexity
What is LAN? Describe it.
Local Area Network.
Its local because its within a single/same building.
Typically have a fast connectivity.
What is MAN? Describe it.
Metropolitan Area Network.
A network in your city - ran and controlled by gov’t entity.
What is WAN? Describe it.
Wide Area Network.
Generally connects other LANs together over a “WIDE AREA” - terrestrial and non-terrestrial connection.
Think of connecting multiple locations throughout the world, together.
What is WLAN? Describe it.
Wireless Local Area Network.
Connection via access points (or WAPs) for mobility within a building or limited geographical area.
What is PAN? Describe it.
Personal Area Network.
What is PAN? Describe it.
Personal Area Network.
Personal connections such as bluetooth, NFC.
What is CAN? Describe it.
Campus Area Network.
Connecting multiple buildings (such as a college) within a limited geographical area.
Using LAN connections with fiber to connect.
What is MPLS? Describe it.
Multiple Protocol Label Switching.
Labels will be put in place for pushing the data to its destination > then the label will pop off (removal) once it get to destination.
What is mGRE? Describe it.
Multipoint Generic Router Encapsulation.
This is within MPLS, mGRE is an additional configuration which is a connection (DMVPN) to send data across different remote sites aside from the main office.
This connect is only formed when it is needed and torn down when done.
What is SD-WAN? Describe it.
Software Defined Networking in a Wide Area Network.
What is SD-WAN? Describe it.
Software Defined Networking in a Wide Area Network.
Cloud based software that can be accessed from remote sites directly without going through a centralized data center.
Doesn’t have to build out an additional network connection to access cloud based recourses.
