2. Short for Disk Operating System, DOS refers to any type of operating system that runs from a disk drive. Today all operating systems could be considered disk operating systems.

3. Short for Denial of Service, a DoS attack is a form of attacking another computer or company by sending millions or more requests every second causing the network to slow down, cause errors or shut down. Because it is difficult for a single individual to generate a DoS attack, these forms of attacks are often created from another company or college and/or worms are created to create zombie computers to create a DoS attack.
