Hello roshni261,
If you're looking to check for any available iOS updates on the device, this page can help note the process: Update your iPhone or iPad - Apple Support
Update your iPhone or iPad wirelessly
1. Back up your device using iCloud or your computer.
2. Plug your device into power and connect to the internet with Wi-Fi.
3. Go to Settings > General, then tap Software Update.
4. If you see more than one software update option available, choose the one that you want to install.
5. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do.
Note that each major iOS version (iOS 17, iOS 16, etc.) will have its own requirements. For the latest version, iOS 17, you may find the compatible devices near the bottom here: iOS 17 - Apple
Cheers.
