The term “big endian” describes the order in which a sequence of bytes is stored in computer memory. In the big endian storage sequence, the most significant value in the sequence, or the “Big” end, is stored at the lowest storage address (ie the first position). The alternative method of memory storage is referred to as little endian, where the least significant value in the sequence is stored first. For example, if the hexadecimal number 4E51 was stored in big endian format it would be saved as the value 4E51. Read More

A fractal antenna is a diamond-shaped antenna that maximizes the total amount of material within a given amount of space that transmits or receives electromagnetic waves. Fractal antennas do this by making each section of the antenna its own separate dipole. Because of this design, fractal antennas operate at many different frequencies and wavebands, allowing them to be used for a wide variety of applications, most of which can be found in the cellular telephone and microwave communication industries. How Fractal Antennas Work Fractal antennas maximize the number of dipoles Read More

An Overview on Performance Monitoring and Management Performance monitoring is the process of accurately and consistently measuring performance, so that you can identify any potential bottlenecks which may be impairing the way in which Active Directory performs within your environment. A bottleneck can take place on any Windows subsystem or network component, and occurs when one resource prevents a different resource from operating optimally. Incorrectly configured settings or the insufficient distribution of resources between network components can result in bottlenecks occurring. Monitoring performance can be considered the initial step in Read More

Recursion is an ability of a program to call itself, either directly or indirectly. Its a programming technique that naturally implements the divide and conquers programming approach. It does the task of calling itself. To do this, it must reduce its size upon every call; else, the process will become infinite. Type of Recursion Direct Recursion Indirect Recursion Example: To compute factorial of a number The above program works as follows, fact(5) = {if(5= =1) is false thus return 5* fact (4)} fact(4) = {if(4= =1) is false thus return Read More

Methyl methacrylate has been used in plastic and resin manufacture for a number of years. It has been found to be significantly irritating to human eyes, skin, and mucous membranes. Exposure to methyl methacrylate has both short and long term effects and includes symptoms such as coughing, wheezing, chest tightness, and some neurological symptoms. The U.S. EPA does not consider the substance to be carcinogenic to humans. What is Methyl Methacrylate Used For? Methyl Methacrylate is primarily used in the production of plastics, resins, and plexiglass. These are then used Read More

An AirCard is a wireless adapter that allows a computer to access high speed broadband Internet from anywhere within the provider’s wireless network. Sierra Wireless originally designed and manufactured aircards, but they are now available through virtually every major cellular service provider in the world including AT&T, Sprint, and Verizon. AirCards require a data plan with a cellular service provider and may be purchased on a monthly, daily, or prepaid basis.   How AirCards Work AirCards are similar to wireless adapters, but instead of receiving signals from a wireless router Read More
