Isobutane

Isomers are compounds with the same molecular, but different structural formulas. Isobutane is an isomer of butane. It belongs to a class of compounds called alkanes, which are chains of carbon atoms where each carbon atom is attached to as many hydrogen atoms as possible.  Its chemical formula is C4H10. Butane consists of four carbon atoms. With four such atoms, it is possible to link the atoms in two completely different ways. The first way, where all the four atoms are linked in a row, is referred to as Butane. Read More

The AVI (Audio Video Interleave) format is a higher-end video format first developed by the Microsoft Corporation. The format is minimally compressed resulting in high video quality, but large file sizes. The WMV (Windows Media Video) file format is supported on a greater number of software platforms and saves disc space when saving video content. A common task that arises for Windows users is to convert AVI to WMV which can be accomplished using free software or web applications.

Cell Phone Frequencies

Last edited by . Total of 3 comments in the discussion.

Cell phone frequencies are the frequency ranges within the Ultra High Frequency (UHF) band that are designated for cell phone use. Bluetooth devices, wireless networks, and television signals also use this frequency band. Although cellular phone systems divide cities and geographic areas into smaller cells of coverage, it allows for a fair amount of frequency reuse across the network. This ultimlately permits significantly more cell phone users to talk simultaneously on a network. How Are Cell Phone Networks Designed? Typically, a cell phone service provider is assigned up to 832 Read More

How to Convert MP3 to WAV

Last edited by . Total of no comments in the discussion.

The MP3 (Moving Pictures Experts Group) audio file format is compressed in order to allow playback and exchange over the Internet and other size constrained media. Although most audio playback devices and software support the MP3 format, the WAV (Waveform audio) format is uncompressed and capable of storing more detail when further manipulating audio files. A common task that arises for end-users is to convert MP3 to WAV format. The task can be accomplished using online tools or free/low-cost software available from third party vendors.

What Are Subatomic Particles?

Last edited by . Total of no comments in the discussion.

Subatomic particles are the most elementary particles found in nature. The three basic subatomic particles that comprise an atom are protons, electrons, and neutrons. The historical definition of a subatomic particle was expanded over the past several decades to include elementary particles that are less complex than an atom and cannot be broken down further. The modern definition of subatomic particles breaks all of them down into either leptons or quarks. Subatomic Particles that Make up an Atom Electron The electron was the first subatomic particle discovered in 1896. U.K. Read More

HVD (Holographic Versatile Disc)

Last edited by . Total of 1 comment in the discussion.

HVD (Holographic Versatile Disc) is the next generation in optical disk technology. HVD is still in a research phase that would phenomenally increase the disk storage capacities over the currently existing HD DVD and Blu-ray optical disk systems. According to published statistics, when produced in full scale, HVDs will have a storage capacity of 3.9 terabytes (39,000 GB) and a data transfer rate of 1 GB/s, which is at least six times more than the speed of DVD players. This would, without a doubt, become a giant step in revolutionizing Read More

Pluggable Authentication Modules

Last edited by . Total of no comments in the discussion.

A Pluggable Authentication Module, or PAM, is a software implementation that allows administrators to significantly change how users log into a server by running a PAM on the server itself. PAMs are used to provide authentication of users as well as perform any tasks that are associated with initializing or terminating the session, such as logging a user into the server, displaying a personalized webpage, and logging the user out of the server when he/she is finished.   How Pluggable Authentication Modules Work PAMs can be embedded into existing servers Read More

Registered Memory

Last edited by . Total of no comments in the discussion.

Registered memory modules have built-in registers on their address and control lines. A register is a very small temporary holding area (usually 64 bits) for data. These registers act as buffers between the CPU and the memory. The use of registered memory increases system reliability, but also slows the system down a very slight bit as data must be moved through the registers. Some systems do not support registered memory, others require registered memory, and many more give you the option to use registered or unregistered memory. The use of Read More
