802.11a is one of the many standards used for high speed wireless networks, usually referred to as Wifi. This standard was created by the IEEE (Institute of Electrical and Electronics Engineers) in 1999 and uses several different frequencies including 5.15-5.35/5.47-5.725/5.725-5.875 GHz to send and receive data from one electronic or computer device to another. There are many different standards of the 802.11 used today for wireless communication; the other popular standards include 802.11b, 802.11g and 802.11n. The standard 802.11a has been available for several years, but has not caught on Read More

A wireless router is a wireless device that connects one computer or a whole network to another computer or network. It is possible to have a wireless network in a home or office. Travelers definitely come across wireless networks at most international airports. A wireless router, which is responsible for sending information from one computer to another, powers a wireless network. The router help the user to share a single Internet connection between two or more computers, which can be on the same floor or even on different floors. Wireless Read More

The toolbar is a component of the Graphical User Interface (GUI) that houses various input and output components such as buttons, menus, icons and so on. End-users can customize toolbars as per their personal requirements. Toolbars can be found in operating systems, software applications, and web browsers. The latest development in toolbar interfacing is the ribbon interface. It basically places groups of toolbars within tabs. The Windows operating system utilizes toolbars in different areas of its GUI. Several of its applications and tools such as Microsoft Office Suite, Internet Explorer, Read More

A pulse jet engine is a type of jet engine that uses pulses of combustion rather than continuous combustion to stay in the air, thereby reducing fuel costs and increasing efficiency. While pulse jet engines have been used in many functional jets, they can also be used for a variety of other applications such as water heating, biomass fuel conversion, fog generators, radio controlled aircraft, target drone aircraft, control line model aircraft, and pulse detonation experiments. Pulse jet engines are most often used in unmanned aircraft due to problems with Read More

Image spamming is a new method of email spamming. The text is imbedded in image or picture files, which most anti-spam software ignore. They are not detected as spam simply because they are pictures and not text. Blocking image spam is proving difficult, as images and pictures (whether as attachments or embedded in the body of the message) are an expected part of a person's daily email intake – for business reasons (e.g., company logos, product shots, electronic newsletters, etc.) or personal purposes (family photos, vacation shots and so on).

The Brookfield Viscometer makes it possible to measure viscosity by employing techniques in viscometry. Viscometers (which can also be called viscosimeters) can measure viscosity through the varying flow conditions of the sample material being tested. They employ a spindle on a shaft that is designed to be dipped or immersed into a liquid that is then rotated. The rotation causes the fluid to produce a drag, which is then measured with the applied torque on the liquid’s viscosity. They are not designed to measure multiple flow conditions, but are possible Read More

ADSL Internet Access Asynchronous Digital Subscriber Line (ADSL) is a broadband Internet option that is commonly available in many locations. Asynchronous only means that the download speeds and the upload speeds are different (with the upload speeds usually being significantly lower) and provides a fast option to browse the web. Internet access through ADSL requires one of three things. The first will be a dedicated phone line to access the ISP through the ADSL modem which some people do if they do not use a land based phone or simply purchase an Read More

UMTS is an abbreviation for Universal Mobile Telecommunications System. It is one of the third-generation (3g) cell phone technologies quickly developing today. UTMS is also referred to as the 3GSM so as to emphasize the coalition between 3G technology and GSM standard. In theory, the UTMS, using W-CDMA, is supposed to be able to transfer up to 14.0 Mbit/s data transfer rates although real uses have shown a transfer rate of 384 Kbit/s to 3.6 Mbit/s with various handsets. However, this speed is still a lot greater than other competing Read More

A vocoder is a device for analyzing and synthesizing human voice. The term itself comes from the words 'voice' and 'encoder'. It has many uses but its main function is in secure voice transmission. The vocoder is useful for voice encryption which ensures that only another person with the voice decoder can listen to what has been said. Thus, a vocoder is basically a voice encryption or encoding device. Interestingly, the vocoder has been around since 1928 (and has been widely applied in the music industry around the '70s). While Read More
