Hello popcorn
If I understand your question correctly, DOS stands for Denial Of Service and is a generic term for a wide range of different techniques intended to do just that - to remotely stop a machine or network from functioning. These attacks are only ever launched for malicious and illegal purposes and the only legitimate reason for studying them is to learn how they can be mitigated

hi popcorn,


In a denial-of-service (DoS) attack, an attacker attempts to prevent legitimate users from accessing information or services. By targeting your computer and its network connection, or the computers and network of the sites you are trying to use, an attacker may be able to prevent you from accessing email, web sites, online accounts (banking, etc.), or other services that rely on the affected computer.

The most common and obvious type of DoS attack occurs when an attacker "floods" a network with information. When you type a URL for a particular web site into your browser, you are sending a request to that site's computer server to view the page. The server can only process a certain number of requests at once, so if an attacker overloads the server with requests, it can't process your request. This is a "denial of service" because you can't access that site.

An attacker can use spam email messages to launch a similar attack on your email account. Whether you have an email account supplied by your employer or one available through a free service such as Yahoo or Hotmail, you are assigned a specific quota, which limits the amount of data you can have in your account at any given time. By sending many, or large, email messages to the account, an attacker can consume your quota, preventing you from receiving legitimate messages.

main type of DOS in the old days was just ping flooding, most DOS attacks can be blocked and stopped now at your router before it gets into your network, even in the DMZ--- I hope this is just for informational purposes.
