DoS attack (aka denial-of-service attack) is a cyber-attack.
The attacker seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting the services of a host connected to the internet.
Denial of service is typically accomplished by flooding the targeted machine or resource with many requests intended to overload systems and prevent some or all legitimate requests from being fulfilled.
