Network Flashcards
Define Topology
Structure of a network
What are the two types of topologies
Physical and Logical
What does physical topology refer to
The actual architecture of a network
What are the two types of physical network topology
Star and Bus
Describe a Physical Star Network Topology
A central hub is connected to each device by a unique wire
Advantages to a physical star network
Packets are sent directly to their recipient through the unique cable - increases privacy
Easy to add and remove clients to and from the network
Each cable has just one device communicating over it - eliminating the possibility of collisions
Failure of one cable does not affect the performance of the rest of the network
Disadvantages to a physical star network
All communications would fail if the central hub fail
Expensive to install thanks to the amount of cable requires
What is a logical topology
The flow of data packets within a network
How can a physical star network act like a logical bus network
If there is a bus protocol running it
What is a host device network
A device that provides services on a network
Describe a Client Server Network
One or more central servers provide services to the clients on the network
Servers are connected to the same way as clients
Clients on the network request services from the servers
Who uses Client Server networking and why
Most schools, colleges and businesses
Allows for central management of clients on the network
Describe a Peer to Peer network
Clients provide services themselves
Every client has equal status
Disadvantages to a Peer to Peer network
All clients which provide services must be running in order for it to be fully functional
Advantages to a peer to peer network
More cost effective as they dont have to pay for a server
Easier to set up and maintain then other networks
