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: -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-4: -When hackers band together to take down a website, they often do so using a Distributed Denial of Service (DDoS) attack. Millions of websites have limited web server and network resources to handle traffic.

Detailed explanation-5: -Smurf attack-a previously exploited DoS attack in which a malicious actor utilizes the broadcast address of vulnerable network by sending spoofed packets, resulting in the flooding of a targeted IP address. Ping flood-this simple denial-of-service attack is based on overwhelming a target with ICMP (ping) packets.
