Your domain name is your website's address - like yourbusiness.com. It's what people type to find you, and you rent it (usually yearly) rather than owning it outright.
Also known as: Domain, web address, URL
In plain English
Your domain name is the address people type to reach you - yourbusiness.com, yourshop.net, whatever you registered. You don't buy it forever; you rent it from a registrar for a year or more at a time, and it has to be renewed or you lose it.
Why it matters for your business
Your domain is your brand's front door - the one piece of your online identity you absolutely must control. Let it expire and a squatter can grab it, or your email and website simply stop working. Auto-renew and keep your registrar login safe.
When you'll run into it
When launching a site, moving hosts (the domain stays put - only DNS changes), or when renewal notices start arriving.
