<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">In computing, a denial-of-service (<a href="http://www.hackthesec.co.in/search/label/DOS" target="_blank">DoS</a>) 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.</span></span></div>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">A distributed denial-of-service (<a href="http://www.hackthesec.co.in/search/label/Ddos%20Attack" target="_blank">DDoS</a>) is where the attack source is more than one, 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.</span></span></div>
