A firewall is a software/hardware tool that is used to protect a computing device from malware/other malicious software or Trojan horses’ intrusion. These external threatening agents often attack a computing device when it is connected to another external computing device that may be affected with a malware. This connection may be via a network etc.
Firewall prevents unauthorized access to a computing device by checking every message transfer to and from the computing device. It restricts any message transfer that does not comply with the defined security standards embedded in it. Firewalls protect a computing device throughout its connection to the internet by continuously monitoring all its activity.
A Database is a physical organization of files that collectively form a data bank. This data-bank has the provision of being able to be accessed by software instances for information retrieval and storage. An instance of a database however, is a virtual structure that is a copy of the entire database environment. This includes the tables within a database, the RDBMS environment and other functions associated with it. Each instance is a separate environment that manages the respective data associated with it for the database users. Every database is associated with one or more databases instances. This helps in easy and timely modification of data and does not involve accessing and running through all the data organized within a database.

Those working in computer and software technical support services might overwhelmingly support these alleged findings through their anecdotes on computer-user buffoonery, but it turns out the survey was a hoax. Major news sources such as the BBC, CNN, NPR, and even CNET covered the story before BBC readership began to doubt the validity of the survey.
