A VPN (Virtual Private Network) server is one that is connected to a Virtual Private Network in order to allow remote users to access files on the server. Companies, government agencies, and various institutions use VPN servers in order to provide users who are away from the server with consistent access to important files and software. Likewise, VPN servers are used domestically to ensure that users have access to computer files while they are away from their home or office. How VPN Servers Work A VPN server is simply one Read More

In the information age, the process of input, delivery, storage, receipt, and categorization of data is critical. Companies, government entities, and individuals have to rely more and more on automated, reliable solutions in order to keep their information safe and readily accessible. A document management system (DMS) is an integrated network of compatible programs or computer systems that reliably handle information for accurate records and usability. As more data is created and shared on a daily basis there is a great demand on keeping it secure and available. Document management Read More

Packet sniffing is the act of intercepting and recording traffic that passes over a specific section or location on a network. As the data passes across the network, a packet sniffer application saves each packet for later use. Network administrators and law enforcement packet sniff for legitimate reasons, but rogue actors who use the captured traffic to steal private and corporate information also use it. How does Packet Sniffing Work? In normal network operations, a computer or networked device only looks at network packets that are addressed to the respective Read More

A microchip, commonly called the integrated circuit, is a tiny electronic circuit. It is made up primarily of semiconductor devices. For the most part, these small microchips are used in nearly every type of electronic device known to man. As the years have gone on from their creation in the late 50s and early 60s, the microchip has become much smaller and more inexpensive to make. Because of this, it has allowed more users to gain access to greater types of electronics. The History of the Microchip In 1968, Jack Read More

A bokode is a new type of technology that was developed by a team at the MIT media lab. A bokode is a digital tag that, like a barcode, can be used to hold information. However, unlike a barcode, a bokode can hold thousands of times of more information than a barcode and can be much smaller than a barcode. A bokode is circular in shape with a diameter of about 3mm. In other words, it is an incredibly small blip that holds considerable amounts of information that the team Read More

PC Based Machine controls are fairly new to industrial environments, however, within the last two decades, PC based machine controls have overtaken the once standard PLC (programmable logic controllers) to run many industrial processes. A machine control is an essential part of modern industrial processes and automation. If you have never visited a factory or assembly line, many of today’s vital components of manufacturing no longer require a human, they are instead computer controlled. While each manufacturer and sometimes each industrial process once required a special PLC with specific hardware Read More

VoIP QoS (Voice over Internet Protocol Quality of Service) is used in VoIP services to determine a VoIP network’s overall performance and make changes to increase the customer satisfaction rate. QoS is used in other systems (like computer networks) as well, but is especially important in VoIP services because of the high demand for prompt, real-time voice packet delivery and call handling. VoIP QoS generally refers to the VoIP system’s bit rate, delay, and bit error rate and provides customers with a realistic idea of the VoIP network’s capabilities. How Read More

Volcanoes are caused by plate tectonics. The entire world is covered in plates that move around due to high pressures underneath them. Depending on the plates, they may rub together resulting in friction or they spread apart resulting in a gap between the two plates. This results in two different types of volcanoes. There are cone-shaped volcanoes, the ones that are similar to mountains, and then there are crack volcanoes, typically only seen under water. Cone Shaped Volcanoes A cone shaped volcanoes is formed when two plates start to rub Read More

WMV (Windows Media Video) is a generic name for video encoding solutions that Microsoft developed. The format is a part of the Windows Media framework that also includes formats like Windows Media Audio (WMA), Advanced Systems Format (ASF), and High Definition Photo (HDP). WMV files use the Microsoft container format and represent Microsoft’s own version of MPEG-4 (Part 2) video encoding technology. First introduced in 1999, the WMV format now competes with other codecs such as DivX and RealVideo as a means of distributing video content on the World Wide Read More

There are two circumstances that can cause someone to want to change his/her AOL password: 1) forgetting the AOL password and needing to recover it and 2)  to change the AOL password. The latter can be because the AOL password has leaked to someone or the user wants to adhere to the good practice of changing his/her password periodically. It is a good practice to change one’s AOL password at least once in a month. Changing an AOL Password The following steps show in detail how to change an AOL Read More
