Synchronous internet speeds mean your download speed is the same as your upload speed. Fiber-optic networks like Antietam’s Flight Internet can provide synchronous Internet connections, while shared networks like DSL can only provide asynchronous Internet connections.
Uploading is sending data from your device or computer, such as email, posting on social media, or sharing your video on a Zoom call. Downloading is receiving data from the Internet, for example watching a YouTube video or Netflix show, scrolling through reels on Instagram, or opening your Thursday evening class assignment online.
