Unit 1.5 V1 Network Topologies
Network Types
Mesh Network
Some or all workstations are
connected to each other
Most are usually connected to the node they
exchange the most data with
Star Network
Each device is connected by an individual
cable directly to the server
These tend to be more reliable and so
are used in schools and offices
Encryption
A method of scrambling data with a key
code which makes no sense
In order to read it you
must have the key
We use it with wifi so if data is
intercepted it has no meaning
Wifi
Wireless Frequency
Radio Waves transmit data packets without wires
It has a cheap set up
It can lose signal
through obstructions
Can connect multiple
devices easily but
more slowly
Can be hacked more easily
The user isn't tied to a specific location
Ethernet
Stable Connection
Less likely to be hacked
Faster traffic speed
Generally gives out a good quality signal
