BNC BNC, which stands for Bayonet Neill-Concelman, is a type of RF connector used for terminating coaxial cable. BNC connectors are used in a variety of consumer electronics, including radios, video devices and certain Ethernet networks. VGA VGA, which stands for Video Graphics Array, is a piece of display hardware. The VGA hardware is a 15-pin D-subminiature connector that can be used to connected video input devices to a VGA monitor. This piece of technology is most commonly found in desktop and laptop computers. BNC to VGA Converter A BNC Read More

The word forensic comes from the Latin word forensis, which means “before the forum,” and refers to something “of, pertaining to, or used in a court of law.” In this day and age, it almost always refers to a method of obtaining criminal evidence in order to use it in a court of law. Forensic science is typically just referred to as “forensics” and is the practical application of numerous sciences to solve legal system related questions in either a civil or criminal action. Using the term “forensics” in place Read More

Inclination is the angle between a satellite orbit and the equator. Inclination is measured as the angle at which the satellite crosses the equator while passing from the southern hemisphere to the northern hemisphere. A satellite travelling in a geostationary obit will have an inclination of zero. Inclination is between 0 and 90 degrees for satellites in non-retrograde orbits, and between 90 and 180 degrees for satellites in retrograde orbits. A satellite in a polar orbit will have an inclination of exactly 90 degree. A satellite with an inclination of Read More

A Bessel filter is a linear filter that is used in electronics and signal processing and has a flat group delay (also referred to as a maximally linear phase response). These filters are commonly used in audio crossover systems and preserve the wave shape of any filtered signals across the group delay in the passband. Who Invented the Bessel Filter? The Bessel filter is named after Friedrich Bessel, a German mathematician who lived from 1784 to 1846 and created the mathematical theory that the filters used today are based on. Read More

An Overview of NTFS In order to store data on a local partition on a Windows server, you have to format it with a file system. The system that you use influences the manner in which data is stored on the disk. It also specifies the security that can be defined for folders and files stored on the partitions. Although Windows servers offer support for the File Allocation Table (FAT) file system, NT file system (NTFS), and CDFS (Compact Disc File System), the file systems generally utilized by local partitions Read More

DNS Queries Overview The naming system used by DNS is a hierarchical namespace, called the DNS namespace. The DNS namespace has a unique root. The root can contain numerous subdomains. Each subdomain also can contain multiple subdomains. Each domain registered in DNS is connected to a DNS name server. The DNS server of a domain provides authoritative replies to queries for that particular domain. The DNS server manages the DNS database that resides on it. DNS server is authoritative for the contiguous portion of the DNS namespace over which it Read More

A Gauss meter is an instrument that measures magnetic field intensity. Electromagnetic fields can be found in numerous locations in the modern world. Electrical wiring in the home, power transmission lines, and household electronics such as televisions, computers, appliances, and clock radios create them. What is an Electromagnetic Field? An electromagnetic field is an invisible line of force created from alternating current flow through appliances or electrical lines. It surrounds all electronic devices. The U.S. Environmental Protection Agency (EPA), through the examination of existing studies, has found that over-exposure to Read More

A hard drive refers to the main storage device for any computer system whether it be a desktop computer or handheld device. Hard drives are usually about the size of a small, paperback book and can exist in both internal and external models. Internal hard drives are usually connected to the computer via an IDE cable while external hard drives use a USB or FireWire cable. Regardless of what kind of hard drive it is or how much information it can hold, all hard drives must be maintained in order Read More

Securing Linux Installation Installing Linux for securing your server depends upon how to install Linux on desktop or server. Installing Linux from untrusted source would not help in potentially securing your server and overcome on other security issues. You should install those packages only which you are in need because there is always a chance that someone could break into your server if security tasks would not be accomplished during installation and troubleshooting them. Verify Packages and Files on Linux CDs Sources of installation packages should be reliable and safer Read More

When a computer reaches a point where it can no longer be repaired because of viruses and malware, or it has gotten to the point where more time is spent trying to load a page than you spend using it, the time might be to do a factory restore of the computer. What this means is that a copy of what the computer looked like when it was shipped from the factory swipes the rest of the computer clean and replaces it with that copied image. In other words, everything Read More
