In computing, a denial-of-service (DoS) attack is an attempt to make a machine or network resource unavailable to its intended users, such as to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet. A distributed denial-of-service (DDoS) is where the attack source is more than one–and often thousands of-unique IP addresses. It is analogous to a group of people crowding the entry door or gate to a shop or business, and not letting legitimate parties enter into the shop or business, disrupting normal operations.
Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile web servers such as banks, credit card payment gateways; but motives of revenge, blackmail or activism can be behind other attacks.
The United States Computer Emergency Readiness Team (US-CERT) defines symptoms of denial-of-service attacks to include:
Denial, in ordinary English usage, is asserting that a statement or allegation is not true. The same word, and also abnegation (German: Verneinung), is used for a psychological defense mechanism postulated by psychoanalyst Sigmund Freud, in which a person is faced with a fact that is too uncomfortable to accept and rejects it instead, insisting that it is not true despite what may be overwhelming evidence. An individual that exhibits such behaviour is described as a denialist or true believer. Denial also could mean denying the happening of an event or the reliability of information, which can lead to a feeling of aloofness and to the ignoring of possibly beneficial information.

What is a Denial of Service Attack? - DOS, DDos, Hacking. In this video you learn what a denial of service attack is and how they are used. This is very easy-to-follow IT training on DOS attacks, covering things like the infamous LOIC (low orbit ion cannon), and a self-hack is demonstrated. Denial of service attacks (dos attack) are the most common way to shut down a website, many websites have been effected by such attacks, including, Facebook, Twitter, eBay, Amazon and multiple US government websites. A ddos attack is where the hacker take control of multiple computers without the owner knowing by using a trojan, this creates what is called a botnet which is effectively a network of computers under the hackers control.

Reuben Paul (@RAPst4r) describes what an Denial of Service (DoS)attack is and the ways in which a hacker can cause a DoS.
Krassimir Tzvetanov, A10 Networks, Inc.. This talk covers the principles and particular implementations of DDoS. It goes in detail as to what are the bottlenecks that are generally exploited/overloaded, the attack types and the solutions to those. - See more at: https://www.nanog.org/meetings/nanog64/agenda#sthash.m3U6Z3nz.dpuf
This chalk talk video, which is part of a broader series on Denial-of-Service attacks, describes how the presence of open DNS resolvers on the Internet can faciliate the creation of denial of service attacks. This particular attack approach, while known a long time ago, continues to be used for Denial-of-Service attacks. In particular, it was used on the recent attacks targeting Spamhaus.

Dr. Soper discusses denial of service attacks and intrusion detection systems. Topics covered include types of denial of service (DoS) attacks, connection flooding, echo chargen attacks, ping of death attacks, smurf attacks, SYN flood attacks, teardrop attacks, distributed denial of service (DDoS) attacks, the scope and operational modes of intrusion detection systems (IDS), and IDS goals and responses to attacks.
