The terms DoS and DDoS are the part of the same unethical glossary. They are somewhat interrelated but they also have their own identify on internet. Let us try to learn about each of them with help of this article. To know more about internet security, contact SRS Networks.

DoS – DoS stands for Denial of Service. This can work either online or offline, but the term is mainly used in context with online denial of service. As is clear from its meaning, if a user is denied to access a service for whatever reason, then it will be termed as DoS.
This too can have two facets. The one is the necessary denial, which means that the user is denied from accessing the service due to rightful reason. For example, if you are using a website’s membership on trial basis and the trail period is over and as per the terms of the site, if you did like to use its service then you have to go premium or pay a certain amount. If you try to use the same account without doing the needful, then you will get a message which will read that you can’t access the service because you do not have the required privileges to do so.
In above case, the website itself has made such a denial because of obvious reason. But imagine, if you upgrade your membership on that website and you still are not able to use the website, because it is down and whenever you try to access it, you get a message which reads something like ‘website is unavailable’ or ‘server is not available at the moment’, then it can be possible that the website is under maintenance and it can also be possible that it has been forced to shut down.
