distributed denial-of-service attack or known as DDoS
A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic.
A DDoS (Distributed Denial of Service) attack is a type of Denial of Service attack that makes the resources of a computer or network unavailable to its intended users. When a computer is getting DDoSed, it can slow down or crash.
A decent firewall will block a Denial of Service Attack (DOS) from sending requests from a single IP address, but a Distributed Denial of Service Attack (DDOS) which is sent from thousands to millions of IPs might not be blocked however most firewalls will only allow a certain amount of connections which is not nearly enough to make your machine deny you service, however it might make your machine run a bit slower.

A denial of service attack. (DoS) This type of attack includes a variety of methods for denying legitimate users access to a network. A Distributed Denial of Service attack (DDos) is more specific type of DoS attack which includes many, mostly infected, devices sending traffic towards a single source to overload the target and prevent normal access.
Distributed Denial of Service (DDoS) attack is another type of DoS attack. These attacks involve numerous systems coordinating a synchronised DoS attack on a single target. The key difference is that the target is attacked from numerous directions simultaneously rather than from a single entity. DDoS attackers frequently employ a , a collection of hijacked devices connected online, to launch large-scale attacks. Attackers use command and control software to exploit security flaws or hardware weaknesses to control many devices.
It is an assault on a network that floods it with so many requests that it is either slowed or completely interrupted. Unlike a virus, which can cause severe damage to databases, a denial of service attack interrupts network service for a long amount of time.
