A DoS attack makes a server or network unavailable by flooding it with attack packets.

Explanation:
Denial of Service attacks aim to make a service unavailable by overwhelming its resources. Flooding a server with attack packets is a classic way to achieve that: the flood consumes bandwidth, CPU, memory, or other resources, so legitimate requests can’t be processed and the service becomes unavailable. This effect can come from various flood types, like ICMP, TCP SYN, or UDP floods, and while the distributed version (DDoS) uses many sources, the end result—unavailability—remains the same.
