A:Answer There are three USB-C ports, one of which is Thunderbolt 4, a headphone/microphone jack, and a micro SD card reader. No USB-A, HDMI, or any other specialized ports, so you'll need to get a hub or dongle for plugging any of those sorts of devices in. RAM does not appear to be upgradeable but if you're brave enough to crack it open there is apparently a second m.2 SSD slot to expand the storage.
