Ring Network: In a ring network each device is connected to two other devices, this forms a ring for the signals to travel around.
Each packet of data on the network travels in one direction and each device receives each packet in turn until the destination
device receives it. Basically every device in a ring network is connected to 2 other devices, making everything connected in a
ring network.
Ring Network
Data transferred quickly
Fast usage
If one device fails all device fails.
No data collisions.
Star Network In a star network each device on the network has its own cable that connects to a switch or hub.
A hub sends every packet of data to every device, whereas a switch only sends a packet of data to the
destination device.
Star Network
Cheap to install
Very expensive
If hub fails all fails
In a bus network all the workstations, servers and printers are joined to one cable,the bus. At each end
of the cable a terminator is fitted to stop signals reflecting back down the bus.
Bus Network
Cheap to install
involves less cabling.
In the main cable fails all fails
Disasters
Disaster recover contains 3
elements
Prevention
Detection
Correction
Even if a disaster occurs a data backup should be in
place. eg Cloud storage.
Firewalls needs to be in place,this boosts up
the security of a network.
The door of a server should be locked so that intruders cant come in
and hack the server etc.
Backing up you system every day
Acceptable use.
Everyone has their own access levels in a server.
Eg in a school students,teachers and administrators have
