Definition: DDOS

Written by

DDoS: [dee-dahs] noun.

DDoS, short for distributed denial of service, is a type of cyberattack used to overwhelm a website or service to the point that it can no longer perform its intended function. DDoS attacks work by sending a flood of requests to targeted servers in such a high volume that the servers can't keep up with the spike in activity. Programs that launch DDoS attacks are now readily available on the internet, and these attacks have grown in size and frequency in recent years as anyone can launch them with relative ease.

Definition: Ping

Written by

Ping: [piNG] verb.

A computer query to another computer on a network to determine whether there is a connection to it. Ping is a simple tool that's similar to sonar: It allows you to send a signal out to another end point and see if you get a response back. Ping uses ICMP (Internet Control Message Protocol) to send small packets of information to other devices and receive packets in turn. These two functions are referred to as Echo Request and Echo Reply. Unlike SNMP, Ping solely tells you whether a device is online or not and how long it takes to get a response from said device.
