A DDoS attack is characterized by overwhelming a target system, network, or website with massive amounts of traffic from multiple sources. The goal is to exhaust resources—such as bandwidth, memory, or processing power—so the service becomes slow, unstable, or completely unavailable to legitimate users.
In simple terms, it’s like a traffic jam on a highway: too many cars (requests) block the road, preventing normal drivers (real users) from reaching their destination.
Many hosts participate in a coordinated attack.

A Denial of Service attack (Abbreviated as DoS).
DDoS stands for Distributed Denial of Service. It’s a type of cyberattack where multiple compromised devices are used together to flood a target system, network, or website with traffic, making it slow or unavailable to real users.
Advanced hardware firewalls can protect a company from falling to a DDOS attack, though not the most sophisticated attacks. Servers can also be configured to minimize the effect of an attack to define limits on application resource allocation. There are also DDOS mitigation appliances available to "sanitize" traffic, though none are perfect and will allow some bad traffic through.
A DDoS attack is characterized by multiple machines spamming specific packets to a target machine with the intent of overloading the target machine so it is unable to service other connecting clients.
A DDoS (Distributed Denial of Service) attack is a type of cyber attack that aims to overwhelm a website or online service with a flood of traffic from multiple sources, making it unavailable to its intended users. The DDoS traffic is typically generated by a large number of computers or Internet-connected devices, often infected with malware, that are controlled by a single entity known as a botnet. These devices, called zombies, send large amounts of traffic to the target, overwhelming its network and servers, causing it to crash or become unavailable.
A DDOS attack is a dedicated denial of service by making a computer's resources unusable to its users. In order to prevent it, you need a good firewall. You can also block those attacking IP addresses.
