FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A Denial-of-Service (DoS) attack is an attack meant to shut down a machine or network, making it inaccessible to its intended users. DoS attacks accomplish this by flooding the target with traffic, or sending it information that triggers a crash.

Detailed explanation-2: -"Denial of service” or “DoS” describes the ultimate goal of a class of cyber attacks designed to render a service inaccessible. The DoS attacks that most people have heard about are those launched against high profile websites, since these are frequently reported by the media.

Detailed explanation-3: -Attackers achieve this by sending more traffic than the target can handle, causing it to fail-making it unable to provide service to its normal users. Examples of targets might include email, online banking, websites, or any other service relying on a targeted network or computer.

Detailed explanation-4: -A DoS attack is a denial of service attack where a computer is used to flood a server with TCP and UDP packets. A DDoS attack is where multiple systems target a single system with a DoS attack. The targeted network is then bombarded with packets from multiple locations. All DDoS = DoS but not all DoS = DDoS.

Detailed explanation-5: -In a distributed denial-of-service (DDoS) attack, multiple compromised computer systems attack a target and cause a denial of service for users of the targeted resource. The target can be a server, website or other network resource.
