A Decision Support System (DSS) is a way to model data and make quality decisions based on it. Making the right decision in business is usually based on data quality and one’s ability to sift through and analyze the data to find trends that solutions and strategies can be created from/for. Decision Support Systems are usually computer applications with a human component. They can sift through large amounts of data and pick between the many choices. What are Decision Support Systems? While many people think of a DSS as a Read More

Despite the claims that Macs are somehow invulnerable to cyber threats, Macs are, in theory, no safer to use than PCs or any other device. However, because PCs are still much more common than Macs and have been around for much longer, virus writers attack Windows users much more often than they attack Mac users. While this means that Mac users are attacked less often, they are still often attacked and are under the same obligations to regularly use antivirus software in order to protect themselves from malicious programs.   Read More

When software and hardware goes through development and testing, the time comes for it to be released throughout the IT infrastructure or to other clients. This falls on the lap of the ITIL Release Management team. This team of individuals ensures that the licensure, tests and version-verified software and hardware is all up to date upon release. This is to ensure that it functions properly when it is placed into the current infrastructure. During the development and implementation of new hardware is also a responsibility of the release management–specifically, the Read More

When earthquake generate seismic waves that travel through the Earth’s crust, they can be recorded on seismographs. When a seismograph records these waves, a trace that shows the amplitude of the wave measurements is generated and converted to the Richter Scale measurement. Depending on the sensitivity of the device, measurements can be made for earthquakes that occur a significant distance away from the measuring device. The Richter scale does not measure the damage that an earthquake causes, just the strength of it. This is because it cannot take into account Read More

A profilometer is an instrument that measures a surface profile to determine its roughness. A surface’s vertical resolution is normally measured at the nanometer level, with lateral resolutions being measured to a less accurate degree. Over the past decade, profilometers have started using laser technology in order to improve the degree to which a surface can be measured without having to physically touch the profile being measured. The most recent laser profilometers have been able to map surfaces in 3D, thereby displaying form and texture over a large area. How Read More

An IP (or Internet Protocol) address conflict occurs when two different systems on the same subnet are assigned or otherwise have their network interface configured to use the same IP address. It is possible to have two systems on different subnets configured with the same IP address, but not have a conflict occur due to routing limitations or because of the effects of NAT or Network Address Translation. Systems with the same IP Address on the same subnet need not have the same netmask or broadcast address for the conflict Read More

An Introduction to the Public Key Infrastructure (PKI) It has grown more important to ensure the confidentiality and integrity for data communication where an organization's network contains intranets, extranets, and Internet Web sites. Because of the connectivity of networks today, an organization's network is exposed to unauthorized users who could possibly attempt to access and manipulate mission critical data or the confidential data of its clients. The need to authenticate the identities of users, computers and even other organizations, has led to the development of the public key infrastructure (PKI). Read More

A Kindle is a portable electronic device that Amazon provides, which allows users to read and access e-books when away from a computer. Kindles provide readers with a means of storing and reading thousands of books anywhere they go by organizing them as AZW files that can be displayed on the Kindle screen and accessed via keys on the front of the Kindle. What is AZW? The AZW file format is the Amazon Kindle’s official format and is used to allow the Kindle to read, store, and access e-books. The Read More

A quantum bit, otherwise known as a qubit, is one of the units used when dealing with quantum information. Another way to look at a qubit is that it is a state vector which is an object of math that can describe different quantum systems. In the case of the qubit, that quantum system is a two-level quantum-mechanical system. One of the biggest discussions when dealing with the qubit is its comparison to the traditional or classical bit when dealing with computer information. Bit vs. Qubit A bit is one Read More
