My new laptop has it.
Your laptop has a built-in digital microphone.
That means I can do without buying a new microphone?
Yes
He just has a microphone and then certainly a webcam. The "digital" should only say that it is super great, so advertising.
Every external microphone is better than that in the laptops.
If the audio quality is enough for you, then yes.
If you can, but if you want better quality, a better microphone would be worth it. However, the microphone in the laptop is sufficient for everyday use.
So the laptop has a built-in microphone. You can use that. Whether a new external micro is necessary depends on what you want to do. If only a microphone is needed every now and then (Skype etc.) then the existing one is enough. If I use the microphone for several hours a day (hotline, order service, etc.) then an external or a heatset would make sense
