Kay [80]

Answer:

A Denial of Service(DoS) is a cyber attack in which the attacker makes a machine or network resource unavailable to its intended users by temporarily interrupting services of a host connected to the Internet.

It works by flooding the targeted system or resource with redundant requests or traffic to overload systems and prevent legitimate and valid requests from being accomplished.
Usually the user establishes a connection by sending a request to server to authenticate it and server responses back by giving authentication permission. This permission is acknowledged by the user and then is enabled on the server.

Contrary to this, in a DOS attach, users send multiple authentication requests to server and these requests contain wrong return addresses so server cant identify the user in order to send permission. The server waits for some time before attempting to close the connection but before it closes the connection the perpetrator sends new set of false requests and this process starts again.
DOS attacks can slow network performance, makes a certain website unavailable and not accessible.
