Types of Network
What are Networks?
- Networks connect devices to share information and resources
- They can be arranged in different structures, called topologies
Types of Network (Topologies)
There are lots of different setups for networks, ranging from wireless to wired, large and small – each with their own benefits.
For the level 4 computing foundations assessment you only need to know four of them, their key features and what each one looks like.
Bus Topology
Bus Topology
All devices are connected to a single central cable
Simple and inexpensive, but a fault in the cable can bring the whole network down
Benefits
- Cost-Effective: Requires minimal cable, making it inexpensive
- Simple Design: Easy to set up and suitable for small networks
Ring Topology
Ring Topology
Devices are connected in a circular loop
Data travels in one direction, which can slow the network if many devices are connected
Benefits
- Efficient Data Flow: Data travels in a predictable path, reducing collisions
- Equal Access: Each device has an equal chance to send data
Mesh Topology
Mesh Topology
Every device is connected to every other device
Highly reliable but costly and complex to set up
Benefits
- High Reliability: Redundancy ensures that data can still flow if a connection fails
- Scalability: Easy to expand by adding new devices
Star Topology
Star Topology
Networks that use a Star Topology are a little difference as they make use of additional hardware.
Devices are connected to a central hub or switch.
The switch is responsible for directing data to the correct destination.
Star Topology networks are reliable, as a failure in one device doesn’t affect others
Benefits
- High Reliability: A single device failure doesn’t affect the rest of the network
- Easy Maintenance: Faults are easy to locate and fix
