Docx file format was introduced to further improve the file manageability and security. Previously doc files have become attractive to virus writers and modification cannot be done simultaneously as docx files can manage.

The conversion of docx documents to other formats can be easy if you have the knowledge on how to or you have the right docx converter software. The conversion to older doc format as used by Adobe pdf format or Microsoft Word is possible and conversion software is offering greater compatibility with other formats.

Docx file format is not just restricted for use in Windows based computer, but also on other operating systems such as Linux and Mac OS. These operating systems have software and filters that allow users to share information using the docx Office XML format.  In the near future, it may have the possibility to open docx format to applications that are installed on smart phones like the Blackberry, iPhone, or phones that have other operating systems.

Common file formats that are generally used in sharing information are MS Word format, Adobe pdf format or binary files with the extension .doc. In most corporate environments, WPD or RTF format are preferred.  Fulfilling the needs of all these recipients can result to implementation the use of docx file format and have the recipient perform their own conversion.

There are situations wherein original docx format may contain confidential or sensitive information, converting it online can be risky in security and probably not permitted. Downloadable converters can be used, as these are both free and can be easily found.

Although the docx file format is a text based format and can easily be accessed by unzipping the package and navigate it to the folder that contains the document .xml, opening this file in this way can have the probability of losing most of the font and paragraph formatting. Also, some of the embedded object may be lost, so docx converters are very important and will eventually play an important role in the years to come.

A firewall is defined as a wall between a computer and hacking activities from intruders. Today, the Internet had made a large contribution in information technology to us. People had been fascinated and enjoyed browsing various websites of their interests. Some geeks have spent almost the entire day surfing the net while other people consider the information accessed through the Internet beneficial and an advantage to them.

However, connecting a computer to the Internet had posed some security risks causing the confidential and sensitive data stored on the computer disk may be accessible to susceptible attacks from an unknown remote hacker. So, it is important that computer users must be aware of these threats and must have the knowledge to protect their critical systems and valuable assets.

A firewall must be used by anyone who connects their computer to the Internet whether it’s just a single computer or a whole corporate network. A firewall can shield both of these against dangerous attacks that can be generated from the local network or from the Internet itself. It further saves valuable resources that are stored in the computer disk from thefts.

Secondly, a firewall is capable of logging all attempts of entering an individual computer or private networks. It poses an alarm every time an unauthorized and suspicious entry is attempted. Other firewalls have the feature of monitoring and logging all outbound data traffic to prevent unauthorized access on valuable resources.

Thirdly, firewalls have also the capability to filter traffics that can be found on destination address, source and port numbers. Traffic can also be filtered by firewalls using the packet attribute and state. Furthermore, a firewall can be organized to allow traffic if it is from a determined trusted host. Also, with a firewall, restriction of traffics from defined ports can be accomplished and these ports can be opened for the data to enter. Some firewalls have the feature that offers protection against harmful viruses, worms and Trojans.

These firewalls are not expensive and most are free of charge for home users. New version of released firewalls is user-friendly and easy to use. Windows operating system had free built-in firewall that users have been grateful with. Moreover, firewalls are available for both hardware and software. Both have similar and different features that are distinct for its purpose.

Therefore, it can be concluded, after reading the three main benefits of firewall that it is necessary to serve as a security product. Without it, our computers can be exposed to destructive intrusion of hackers.
