What is the difference between hub and router?
About 27.5 billion dollars worth of new computer equipment is sold each year in the United States, where router and hub are two kinds of network devices.
A hub and router are devices used in networks to pass information from one computer to another. The router is part of the third layer in the OSI model, known as the network layer, while a hub is located in the first layer, also known as the physical layer.
The important difference between hub and router is the data transmission address. Hub uses the physical address while router uses the IP address to identify the devices.
What Is Hub?
A hub is a networking device that allows you to transmit signals to every port except the one from which signals originate. It connects segments of a local area network (LAN) and operates on the physical layer of the OSI model.
In network-compatible computing, a hub is a device that allows several computers to connect to the same network. Ethernet, Firewire, and Universal Serial Bus (USB) are some of the ways to connect a hub.
Hubs don’t analyze and process data based on the hardware and software. Instead, they make decisions purely on a physical basis.
There are three types of hubs—active hubs, passive hubs and intelligent hub.
Active hubs regenerate the signals we send out, as well as amplify them. An active hub needs electricity to work.
In a LAN, a passive hub simply distributes the signal coming from the previous ports (without regenerating any signal or amplifying it). Passive hubs don’t require any electricity to work.
A manageable hub allows network administrators to monitor network traffic, and you can configure each port on it individually.
What Is Router?
A router is a networking device that connects two or more networks by forwarding data packets between them. It operates at Layer 3 of the OSI model and is used to connect two or more networks. A router is a device that uses IP addresses to route or forward data from one network to another. A router is the smartest and most difficult of the hub and switch combinations.
There are 5 types of router – Wireless router, wired router, edge router, core router and virtual router.
Wireless routers allow you to share an Internet connection among multiple devices, such as your smartphone, laptop, or tablet. If you place the wireless router indoors, its connection will reach about 150 feet; if it’s placed outdoors, then the range can be more than 300 feet.
A wireless router connects to a modem using an Ethernet cable. It converts binary data packets into radio signals and broadcasts them using antennae. A wireless router does not create a local area network; instead, it creates a WLAN—a wireless local area network—which connects multiple devices using wireless communication.
Just as a wireless router connects to a modem with an Ethernet cable, so too does a wired router use an Ethernet cable. With that cable connected, and separate cables then connecting to the devices on your network, you can create your own local area network (LAN), and link all your devices on that LAN to the Internet.
If you are at a bank or a small campus, you can see that the computers are connected to the Internet using an Ethernet cable. That is the wired router.
The distribution router is the second name given to the edge of a router, which sits on the edge of the backbone of the network and can be connected on either wired or wireless lines. It sends internet data packets to one or more networks, but not within networks.
Core routers run on the backbone of a network, while edge routers distribute packets across multiple networks. Core routers are responsible for heavy data transfers.
You can turn your computer into a router, creating a virtual router and allowing other devices to connect to your computer in the same way they would connect to a standalone router.
Difference Between Hub and Router: Hub Vs Router
|In a Local Area Network(LAN), a hub is a sort of equipment that serves as a connection point for numerous devices .||Objective||A router is a networking device that sends data packets from one computer network to another.|
|Half-Duplex||Mode of transmission||Full-Duplex|

Advantages of Hubs
- Network hub is less expensive to operate
- A network hub gives you full control over your networking needs
- A network hub can easily expand your existing wireless network for better coverage.
- There is no installation required and no configuration required for a network hub setup.
- Compatible with different brands
- They can provide a central location for all of your shared devices.
Disadvantages of Hubs
- Can’t handle modern traffic demands
- Difficulty to switch between devices
- You can’t control who’s on the network
- The more devices you have connected, the greater your risk of problems.
- The bandwidth is limited by the available bandwidth of the network connection.
- It’s mostly half-Duplex
Advantages of router
- Router connects multiple computers and devices at the same time.
- Routers have built-in firewall protection that keeps your computer safe from unwanted attacks from the Internet.
- Network maintenance and troubleshooting via SW-based features.
- Wireless router provide mobility and portability
- With a router you can prioritize your network traffic so that certain types of traffic always has priority over others, ensuring that more important data gets through quicker than less important data.
- It helps you to define the paths that data traffic will follow through a network.
Disadvantages of router
- Configuration is not simple as it looks.
- Routers are prone to hacking
- Needs regular maintenance
- It is more expensive than a switch
- Small wireless range
- It consumes a lot of memory and this can cause the memory to be swamped, resulting in slowness.
Because users can get confused by the terms hub and router, understanding the differences between them can help you choose the right devices for your network. Hubs and routers are networking devices that differ from each other in the ways they send, receive, and process data. Hubs are used to connect devices on a local network, while routers are used to connect different networks.
