Put simply, DoS (Denial of Service) attacks are weaker than DDoS attacks. They’re more don’t rely on botnets. Because of the way they work, DoS attacks normally target individuals rather than businesses.
Unlike DDoS attacks, a DoS attack can only force you offline for a couple of minutes, usually re-starting your router is all you need to do. Worst case scenario, you’ll be without web access for a few hours. Sometimes, though, you’ll only experience slowdowns, and will still be able to browse the web.
DoS attacks shouldn’t be underestimated. They're annoying and cause damage. For example, they could continuously interrupt your online gaming sessions or stop you from doing your job if you work remotely.
