Ports decide what you can plug in. Here's a plain-English guide to the connectors on a modern laptop and what each one does.
| Port | What it's for |
|---|---|
| USB-C | Reversible all-rounder: data, charging, and video to a monitor through one small port |
| USB-A | The classic rectangular USB for mice, keyboards, flash drives, and printers |
| HDMI | Connects to TVs and monitors for a second screen |
| 3.5mm audio | Headphones and headsets |
| microSD / SD | Extra storage and transferring photos from a camera |
How many ports do you need?
If you use a mouse, an external monitor, and a flash drive at once, make sure the laptop has enough ports — or plan for an inexpensive USB-C hub, which adds several ports through a single connector.
