When the Earth begins to get too hot, the water increases in temperature. As the water continues to get hotter, it begins to undergo a phase change in which water turns to gas. The water droplets turn into water vapor because the temperature has caused the individual water molecules to speed up considerably. This process of heating water up and turning it into vapor is known as evaporation. Evaporation should not be confused with boiling because when water undergoes evaporation, only water molecules that are on the surface of the Read More

True antigravity propulsion involves using a material or technological effect that counteracts the effects of gravity without using aerodynamic lift, electromagnetism, or some other balancing force. Likewise, antigravity does not refer to situations in which an object or person experiences lack of weight such as being in a pool, free fall, or high altitude orbit. Virtually all antigravity propulsion systems and experiments that scientists introduced to the public and that supposedly defied gravity could not be supported with concrete evidence. Furthermore, no third party could recreate it. This fact has Read More

A Unix shell is the program which reads user input from the command line and executes actions based upon that input. There are two general families of Unix shells, the Bourne family and the C family. The Bourne shell was the original Unix shell. The C shell was the first competing Unix shell. tcsh is an improved variant of the C shell. The Korn Shell (ksh) and the Bourne Again Shell (bash) are improved variants of the Bourne shell. Other less popular shells include the zsh, rc, and es shells. Read More

Linux is a free, open source operating system that competes with the Windows Operating Systems and Mac OS X. Linux is widely used on a number of devices such as servers, desktops, laptops, smartphones, PDAs, game consoles, tablet computers, supercomputers, and mainframes. Linux controls only about 4.9% of the market share of desktop computers while controlling roughly 40% of the market share of servers. Linux was created and remains to be modified on a routine basis by the community at large as well as specific designers who have been working Read More

IIS Administration Tools and Methods. The administration methods and management tools which you can use to administer IIS are listed below: Microsoft Management Console (MMC) tools under the Administrative Tools Menu. The primary MMC used to administer IIS is the IIS Manager (see below). You can also use the Computer Management console to perform administration tasks for IIS.

VGA (Video Graphics Array) cables connect computers with monitors or television sets. The cables are based on the graphics standard that IBM developed on personal computers sold during the 1980s. Since that time, almost all personal computers that are built to support the Windows operating system (OS) incorporate support for VGA connections and the more advanced HD connections that have been created and implemented since VGA was first invented. How do VGA Connections Work? The term VGA refers to the type of cable used to connect a display to a Read More
