Prior to revising your Virtual Memory settings, you should check on how much Virtual Memory you would need, based on how much RAM you do have and how memory-intensive your normal applications are. Specifying Virtual Memory Settings The best way to do this is by installing the built-in System Monitor applet from the Add/Remove Program component in the Control Panel. Go to Windows Setup, highlight System Tools and click Details. Put a check on System Monitor and then hit the OK button, and exit the program. A prompt will appear Read More

An Android is a smartphone that Google created that combines the functionality of a cell phone and a computer. While the Android does not include many features that a real computer does, it allows the user to take advantage of a wide variety of applications that can be used to perform diverse tasks that the Android itself does not support. Apple as well as its users create these applications. In order to create Android applications, users can implement the following programs and reference materials:   What is the Android Software Read More

Potassium benzoate is the potassium salt of benzoic acid. Benzoic acids are weak acids that are used as food preservatives. Potassium benzoate is also commonly used for preserving food. It is primarily used to inhibit mold and bacteria growth. This allows the product that potassium benzoate preserves to last longer on the shelf, thereby increasing profits for the company that produced it. The ideal pH for products using potassium benzoate as a preservative is below 4.5 because that is where it exists as benzoic acid. Acidic food or beverages such Read More

A spot beam is a beam of radio signals that is directed towards a specific area on the Earth’s surface. Spot beams are the opposite of broad beams, which are beams that are directed towards a large area of the Earth’s surface. While broad beams are used for general telecommunication and surveillance, spot beams are used for magnified views of the Earth and are ideal for targeting purposes and close-up surveillance of specific areas. Spot beams are also used in telecommunications for direct links between a specific satellite and a Read More

Magnets are mainly characterized for having poles: if you put together poles of the same charge they repel and if you put together charges of different pole, they attract. A body will be under Magnetic Levitation when it floats due to that special repelling quality of the magnets, i.e. when the force generated by the electromagnetic repulsion is strong enough to balance the weight of the object. Methods for Obtaining Magnetic Levitation There are different methods for obtaining Magnetic Levitation. For heavy objects, the main are electromagnetic suspension and electrodynamic Read More

Voltage is the measurement for the electrical force between two points that drives the current. More specifically, voltage is the measure of the energy per unit charge that is equal to the electrical potential difference between two measured points. Volts are normally measured by a voltmeter. Voltage drop is the reduction in voltage in an electrical circuit between the source of power and the load on a circuit. Many electrical codes throughout the United States and the developed world set specific guidelines for the maximum voltage drop permitted in an Read More

L2 cache is the second tier of a multi-cache memory system and provides memory to a processor without delay. An L2 cache sits between an L1 and L3 cache and is generally either 256 KB or 512 KB in size. An L2 cache contains frequently used information and prevents the processor from having to search the L3 cache or RAM, which are both much larger in size. Although a processor will first search the L1 cache, it is often the L2 cache that contains the needed information due to the Read More

Sound information that passes through computer speakers can easily be something that one wishes to keep as a recorded piece to use for later. This is a great option to have when one wishes to be able to playback the sound on a different device such as a mobile phone or mp3 player. The simplest answer may seem to be to use a microphone to record the audio. While this option essentially works, it provides very low quality recording with a great deal of distortion. It is entirely possible to Read More

Macintosh Services Overview While in the earlier days, it was somewhat difficult to integrate Macintosh networks and Windows networks because each operating system basically used different protocols, and files structures and systems. To deal with these integration issues, Microsoft has since introduced the File Server for Macintosh (FSM) and Print Server for Macintosh (PSM) services with Windows NT Server. These FSM and PSM Macintosh services are also included with Windows 2000 and Windows Server 2003. When the FSM and PSM Macintosh services are installed, it enables Macintosh clients to access Read More

Fixed/Mobile Mobile Circuit/Packet Circuit Max Bandwidth 57.6Kb Range Coverage area of host network Frequency Frequency of host network Host Network GSM Definer ETSI (European Telecommunications Standards Institute) URL http://www.etsi.org/ HSCSD (High Speed Circuit Switched Data) is a specification for data transfer over GSM networks. HSCSD utilizes up to four 9.6Kb or 14.4Kb time slots, for a total bandwidth of 38.4Kb or 57.6Kb. 14.4Kb time slots are only available on GSM networks that operate at 1,800MHz. 900Mhz GSM networks are limited to 9.6Kb time slots. Therefore, HSCSD is limited to 38.4Kbps Read More
