Switches #
Switches are the backbone of a business network. They link together all devices — computers, printers, servers, VoIP phones, etc. Once everything’s connected through a switch, those devices can ‘talk’ to each other and share information smoothly, no matter where they are in the building.
Routers #
A router links together multiple switches (and the networks attached to them) to create something bigger — whether that’s within a single site or across multiple locations.
When you’re setting up a small business network, you’ll always need at least one router. On top of joining networks together, it’s also what gets you online. No router, no Internet.
Hubs #
A hub sits at the centre of a LAN and connects multiple devices, acting like a basic distribution point. When data comes in, the hub just sends it out to every port. Hubs operate at Layer 1 (the physical layer), which means they don’t process or analyse any data. There are different types of hubs, such as:
- Passive: these are the most basic. They connect devices via cables but don’t boost or process the signal. Think of them as multi-way extension leads for network cables.
- Active Hubs: do the same job as passive ones but with a boost. They use a power supply to amplify signals passing through them, helping maintain data quality over longer distances. Naturally, they cost a bit more.
- Intelligent Hubs: these take things a step further. Intelligent hubs include management features, using management information bases to monitor traffic, adjust port configurations and help diagnose network problems.
If you’re thinking of starting a network for your SMB, knowing of key network components like this is a must.
