Key Differences
A Router and a Switch are both integral components in the realm of networking, but they serve distinct purposes. While a Router is primarily responsible for forwarding data packets between different networks, a Switch operates within a single network, connecting multiple devices together.
The Router acts as the intermediary between your local area network (LAN) and the wider internet. It assigns local IP addresses and manages the flow of data in and out of the network. Conversely, a Switch doesn't concern itself with different networks or the internet. Instead, it ensures that data within the LAN reaches the correct device.
From a functionality perspective, the Router handles more complex tasks like Network Address Translation (NAT) and Dynamic Host Configuration Protocol (DHCP). The Switch, meanwhile, uses MAC addresses to direct data to the appropriate device within the network, ensuring efficient communication.
In simpler terms, if you imagine the internet as a vast city, the Router would be akin to the city's main entrance, managing traffic in and out. The Switch, on the other hand, would be the internal roads, ensuring residents (devices) communicate with each other seamlessly.

Common Curiosities
Why does a Router use IP addresses while a Switch uses MAC addresses?
A Router directs traffic between networks using IP addresses, while a Switch directs traffic within a network using MAC addresses.
Can a Switch assign IP addresses?
Typically, a Switch does not assign IP addresses. That's a function of a Router or a DHCP server.
Do I need both a Router and a Switch in my home network?
It depends on your needs. While a Router can connect a few devices, a Switch is helpful if you have many devices in the same network.
Does a Router connect devices like a Switch?
While a Router can connect devices, its main role is to connect different networks, whereas a Switch connects devices within the same network.
Can I use just a Switch for internet access?
A Switch alone cannot provide internet access; you'd need a Router to connect to the internet.
