You see devices called “hub,” “switch,” or “router” when setting up networks. Each one has a specific job. A hub vs. switch vs. router question pops up when linking computers or adding Wi‑Fi. A hub in a network box repeats messages to all ports. On the other hand, a network switch sends data only where it should go.
A router and switch together connect your gadgets to each other and the internet. Choosing the right one improves speed and stops headaches. This article explains each tool simply, so you can set up home or office networks correctly.
What Is a Hub and How Does It Work?
A hub device is the simplest. You plug Ethernet cables into it. When one port sends data, it rebroadcasts to all other ports. This repeats messages even if only one device needs it. Think of a megaphone in a hall; it blasts to all ears.
Hubs lack intelligence, and they don’t check addresses or route data. That causes delays when the network is busy. In early LANs, hubs were cheap and easy. But in homes today, they slow things down and create collisions. That’s why hubs are rare now.
Types of Hub
While hubs are now mostly outdated, they were once common in simpler networks. Different types offered various capabilities depending on power needs, signal strength, or environment. Some boosted signal quality, others just split it. Here are some types of hubs you need to know about:
- Passive hub: doesn’t amplify, just splits signal passively
- Active hub: includes electronics to boost and clean signals
- USB hub: offers more USB ports (not for networks)
- Industrial hub: built tough, used in factories or outdoors
- Power‑over‑Ethernet hub: uncommon, delivers power and data
What Is a Switch and How Does It Work?
So, what is a network switch? It’s smarter than a hub. It reads data packets and sends them only to the correct device. Imagine a mail sorter delivering letters to proper mailboxes. That reduces traffic and collisions.
Switches come in many sizes, from small desktop models to big 48-port racks. They often support fast speeds (1 Gbps or more). Some add Power over Ethernet to run Wi‑Fi points or cameras. Switches work quietly in the background to keep devices talking fast.
Types of Switch
Switch network options vary by how much control you need. Some work right out of the box, others let you fine-tune traffic. Knowing the types of networking switch devices helps you scale from home setups to large networks. These are the most common switch network device styles.
- Unmanaged switch: set‑and‑forget, no configuration needed
- Managed switch: adjustable settings, VLANs, traffic control
- PoE switch: powers connected devices through Ethernet
What Is a Router and How Does It Work?
A router connects your local network to the Internet. It gives IP addresses, creates Wi‑Fi, and keeps your connection safe from outside threats. Often called a network hub router, this device handles traffic entering and leaving your home network.
Routers decide where data travels next—across your network or out to the internet. Most modern routers include wired Ethernet ports and wireless radios, so one box can be a router, plus a switch and Wi‑Fi hub.
Types of Routers
Not all routers work the same. From simple wife hubs for home to complex routers with hub units used in offices, there’s a type for each situation. These router and switch options impact performance, protection, and internet sharing. Pick one based on speed, range, and number of connected devices.
- Home router: delivers Wi‑Fi plus several Ethernet ports
- Business router: includes VLANs, VPN, and firewall settings
- Core router: used by ISPs to direct large volumes of traffic
- Virtual router: software‑based routing inside servers
- 4G/5G router: connects via cell networks for the internet
Hub vs. Switch vs. Router: Key Differences
Each device has a unique role. Choosing correctly speeds up your network and avoids errors. Most home setups use a router with built-in switch ports. Larger networks may add stand‑alone switches. On the other hand, hubs are mainly obsolete. Here is a table that explains it too comprehensively:
|

Connects multiple different networks and forwards data packets between them. |
|
OSI Layer |
Layer 1 (Physical Layer) |
Layer 2 (Data Link Layer) |
Layer 3 (Network Layer) |
|
Data Transmission Method |

Forwards data to a specific IP address. |
|
Decision-Making Basis |
No intelligence; simply repeats signals. |
MAC address table (CAM table). |
IP address table (routing table). |
|
Collision Domain |
All ports are in a single collision domain. (Larger collision domain = more collisions) |
Each port is its own collision domain. (Smaller collision domain = fewer collisions) |
Each interface is its own collision domain. |
|
Broadcast Domain |
All ports are in a single broadcast domain. |
All ports are typically in a single broadcast domain (unless VLANs are configured). |
Each interface represents a different broadcast domain. |
|
Performance |
Low; causes network congestion and collisions. |
High reduces collisions and improves network efficiency. |
High; handles network traffic routing efficiently. |
|
Intelligence |
"Dumb" device; no processing capability. |
"Smart device; learns MAC addresses. |

|
Security |
Vies low; all data is sent to all devices. |
Medium: data is sent only to the destination, improving privacy. |
High: implements firewalls and network segmentation for security. |
|
Cost |
Very low. |
Medium. |
High. |
|
Usage/Application |
Obsolete for most modern networks; sometimes used in very basic, small, or legacy networks. |
Local Area Networks (LANs) in homes, offices, and data centers. |
Connecting different LANs, LANs to WANs (like the internet), and enabling internet access. |
|

No (operates at Layer 3, not concerned with MAC addresses for routing). |
|
IP Address Usage |
Does not use IP addresses. |
Does not use IP addresses (operates based on MAC addresses)? |
Uses IP addresses to route packets between networks. |

Here’s a quick distillation:
- Hubs are out-of-date, simple splitters
- Switches route data efficiently between local devices
- Routers link your network to the internet while managing addresses and security
Conclusion
Hubs, switches, and routers each serve clear network functions. Hubs repeat, switches direct, and routers connect to the web. For a reliable home or office network, routers and switches are essential. For reliable streaming, fast file sharing, and secure Wi‑Fi, use a router and switch combo. Hubs can slow you down.

FAQs
Can I use a hub instead of a router?
No. Hubs only share local network signals. They don’t provide internet connectivity or route traffic externally.
Does a switch improve Wi-Fi speed?
A switch improves wired speeds only. Wi‑Fi speed depends on the router and wireless signal quality.
Can one device be both a switch and a router?
Yes. Many routers include switch ports and wireless access. They provide both local and internet connectivity.
Will adding switches help with fluctuating internet speed?
Switches improve internal traffic flow but don’t speed up the internet provided by your ISP.
Should I avoid using hubs today?
Yes. Hubs are outdated. They cause network slowdowns and collisions. Modern setups use switches and routers.
