Understanding network hardware helps you manage data flow. Here is a breakdown of the main devices.
Modem A modem connects you to the internet. It limits the number of devices you connect to your service provider.
Router A router directs data packets. When you visit a website, your request splits into small packets. The router moves these packets to the correct destination.
Switch A switch connects wired devices like computers and printers in a local network. It uses MAC addresses to send data only to the specific device that needs it. This reduces unnecessary traffic.
Firewall A firewall acts as a security guard. It sits between your local network and the internet. It checks all incoming and outgoing traffic based on set rules. Every packet must pass through it to keep your network safe.
Load Balancer A load balancer acts like a traffic cop. It sits between users and your backend servers. It distributes client requests across multiple servers.
Benefits of a Load Balancer:
- It prevents servers from getting overwhelmed.
- It stops system crashes.
- It speeds up response times.
- It ensures your service stays online.
