Chapter 1 - Networks Flashcards
What are the two main types of network architecture?
Peer-to-Peer and Client-to-Server
What is a Peer-to-Peer Network?
A Peer-to-Peer network is one where computers connected together do not have any central authority. The authority lies with the computer that has the desired resource being requested from it to perform a security check for proper access rights.
What is a Client-to-Server Network?
In a Client-to-Server network a single server uses a network operating system to manage the whole network. This makes the network more organized, files are easier to locate, and security is centralized.
Match the charateristic to its network architecture:
All computers have equal authority.
P2P
Match the charateristic to its network architecture:
Security is decentralized
P2P
Match the charateristic to its network architecture:
Computers can be clients or servers
P2P
Match the charateristic to its network architecture:
Computers can use Windows, Mac, or Unix/Linux operating systems.
P2P, C2S
Match the charateristic to its network architecture:
Data backups must be managed individually for each computer.
P2P
Match the charateristic to its network architecture:
Specialized computers have designated authority for the network.
C2S
Match the charateristic to its network architecture:
Security is managed centrally.
C2S
Match the charateristic to its network architecture:
Data backups and other operations can be managed from a central location.
C2S
What are the seven network topologies?
Bus, Star, Ring, Mesh,
Point-to-Point, Point-to-Multipoint, Hybrid
What is a Bus Topology?
The bus topology consist of two distinct and terminated ends, with each of its computers connecting to one unbroken cable running its entire length.
What is a Star Topology?
A star topology consists of central point, such as a hub or switch or an access point, to which computers are connected with their own individual cables or wireless connections.
What is a Ring Topology?
A ring topology consists of network, in which each computer is directly connected to other computers, the networks primary cable forms a ring as data flows from computer to computer back to the source.
What is a Mesh Topology?
A mesh topology consists of a network in which there is a path from every machine to every other machine.
What is a Hybrid Topology?
A hybrid mesh topology consists of two typologies, physical or logical, combined within the same network.
What is a Point-to-Point Topolgy?
In a point-to-point topology you have a direct connection between two routers or switches, giving you one communication path. The routers in a point-to-point topology can either be linked by a serial cable, making it a physical network. If the routers are farther apart and connected only via a circuit within a Frame Relay or MPLS network, its a logical network.
What is a Point-to-Multipoint topology?
A point-to-multipoint topologyconsists of a succession of connections between an interface on one router and multiple destinstion routers – one point of connection to multiple points of connection.
Match the charateristic to its network topology:
A central cable used to join all computers must be terminated at both ends.
Bus
Match the charateristic to its network topology:
Addresses complex needs by using two or more networking topologies.
Hybrid
Match the charateristic to its network topology:
All data traffic travels in one direction and at a high rate of speed.
Ring
Match the charateristic to its network topology:
All hosts are connected to a single cable that runs the length of the network.
Bus
Match the charateristic to its network topology:
All hosts connect to a central hub or switch using their own individual cables or wireless connections.
Star
Match the charateristic to its network topology:
All hosts must have a path to every machine on the network.
Mesh
Match the charateristic to its network topology:
Dependence on a central device, such as a hub, allows for a single point of failure.
Star
Match the charateristic to its network topology:
Easy to expand the network without causing any disruption.
Star
Match the charateristic to its network topology:
Has the highest level of fault tolerance.
Mesh
Match the charateristic to its network topology:
Expanding the network can cause network disruption.
Bus
Match the charateristic to its network topology:
Hosts connect to a central cable using T - connectors or taps.
Bus
Match the charateristic to its network topology:
Is typically used with token passing protocols to ensure that all systems can communicate with minimal disruption from data collisions.
Ring
Match the charateristic to its network topology:
Made up of a single link between two devices.
Point-to-Point
Match the charateristic to its network topology:
Multiple sites are connected to a single location; typically using routers to create the connections and manage data transmissions between locations.
Point-to-Multipoint
Match the charateristic to its network topology:
Rarely used in corporate LANs because the topology is too complicated to manage all connections.
Mesh
Match the charateristic to its network topology:
The topology is highly fault tolerant. If one cable breaks, only one host would be unable to communicate
Star
Match the charateristic to its network topology:
The topology is very difficult to troubleshoot.
Bus
Match the charateristic to its network topology:
The topology offers no fault tolerance. If one cable breaks all hosts are unable to communicate.
Bus
Match the charateristic to its network topology:
This configuration is more commonly used with Fiber Distributed Data Interface (FDDI) and SONET protocols.
Ring
Match the charateristic to its network topology:
This topology is easy to troubleshoot.
Star
What is MPLS and its Advantages?
MULTIPROTOCOL LABEL SWITCHING
MPLS is a switching mechanism that imposes labels (numbers) to data and then uses those labels to forward data when it arrives at the MPLS network.
