In this day and age, most people are exchanging the pen and paper for a computer with a word processing progamme. Nowadays, the alternative to sending messages via snail mail is the use of the Internet to send electronic mail. Sometimes people wish to remain anonymous when sending messages. This comes in handy for various reasons, whether for privacy protection, to avoid embarrassment of any sort, or to voice an opinion without fear of direct retaliation from another party. This is done through use of remailers, which, in essence, are Read More

One of the biggest factors that lead to poor computer performance is simply lack of knowledge about the computer in question. Technical skills aside, it is extremely important that users are able to recognize problems with their computer and associate those problems with common computer glitches, viruses, double entry of files, and missing files that may confuse or complicate some computer processes. Fortunately, users can take advantage of computer diagnostics software that can recognize and fix these problems without the user needing any kind of technical knowledge or experience. This Read More

DirectX is a collection of software necessary for different multimedia applications to run properly. Specifically, many people who play computer games run into the problem of having to update their DirectX. However, when buying a new game, for example, it helps to know what version of DirectX is installed on the computer so you can decide whether you need to upgrade or not. One of the things that should be understood about DirectX is that, for the most part, it is backwards compatible. If you have DirectX 9 installed on Read More

Symmetric Digital Subscriber Line (SDSL) is a kind of one kind of Digital Subscriber Line (DSL) used to provide high-speed Internet connectivity. Symmetric DSL is called “symmetrical” because the upstream and downstream connections have the same bandwidth. SDSL maintains the same high speed in both directions while working over the existing “twisted-pair” cables that exist in all telephone equipment. SDSL requires only one pair of copper wires to support a connection. These wires may reach as long as 3 kilometers. How SDSL Differs from ADSL Unlike the much more common Read More

Hurricanes are caused by immense low pressured formed over the warm oceans in the summer and early fall months. With this low pressure, water vapor is evaporated off of the ocean surface. This water vapor releases the latent heat of condensation which causes all of the water to begin forming into clouds. This condensation forms warmth around the surrounding air. Typically, a wind shear (change in wind speed or direction) causes the top of the tropical storm to blow off and destroys the fledgling hurricane. However, if there is a Read More

MRAM (Magnetoresistive Random Access Memory) is being considered as a viable replacement for current DRAM technology. Its key difference to the latter is its use of magnetic fields to save memory bits which makes the memory "permanent." As such, MRAM technology allows for faster access and data security. Current RAM Technology Current RAM technology uses an electrical charge to store memory bits. Microminiaturized capacitors and transistors in an integrated circuit are 'stacked up' to create high-density, large-memory but physically small chips. A typical memory chip stores up to 1 Gb Read More

A pointer is a variable that holds the memory address, usually a location of another variable in memory. The use of pointers is critical for the successful programming in C++. The three reasons that support this are, Pointers provide the means through which the memory location of a variable can be directly accessed and hence can be manipulated in any way. Pointers support dynamic allocation routines. Pointers can improve the efficiency of certain routines. Since pointers hold memory location of another variable and also facilitate dynamic memory allocation, we must Read More
