ADSL Tester

ADSL stands for Asymmetric Digital Subscriber Line, which is a form of high-speed Internet access using standard phone lines. Unlike the standard modem, which can only provide download speeds of up to 56 kbps, ADSL can provide you with download speeds of up to eight mbps.

The download speed ADSL provides is variable, depending on your distance to the central office or to a remote router. The maximum download speed of eight mbps is only possible if you live within one mile of the office. The typical ADSL subscriber can expect download speeds of up to four mbps.

The main disadvantage of the ADSL is the fact that its high speed is only one-way. The upload speed of this Internet service is very slow, nearly comparable to a dial-up connection. This is why ADSL is heavily marketed to passive internet users, those that do not upload files on a regular basis. The typical Internet user only uses the Internet to download information. Therefore, high speed for one direction is generally adequate for them.

ADSL Line Tester Information

When using ADSL, your connection speed will vary with your distance to the central office. You will need a way to test the speed of your line. This is what an ADSL line tester is for. It will calculate your distance from the central office, or router, and determine the data rates possible. Having a line tester will assist your service provider in accelerating the installation of your service.

Different testers will give you different functions. A basic line tester can ping your line. It will send out a signal and measure the time it takes for it to reach its destination and come back to you. More advanced line testers can do more than simply ping your line. Some can also test all the functions of your DSL modem, as well as check the physical layers of the connection.

ADSL Speed Tests

ADSL is a new technology that stands for Asymmetric Digital Subscriber Line. This is commonly known as DSL and can provide high speed internet access to homes using the standard copper telephone lines. It is different from Internet access that is provided through cable television lines.

DSL is the primary competition of cable in the Internet service provider market. The primary advantage of cable is that it has faster and more flexible download and upload speeds compared to DSL. While DSL can provide you with a fast download speed, it is only one-way. Its upload speed is significantly slower than what cable can provide you. This is why DSL is primarily marketed to passive Internet users, meaning those who do not need to upload files frequently.

DSL does have some advantages over cable. Its lower cost and wider range of availability might appeal to more prudent consumers. In smaller, lower-market cities, cable Internet access might not be available. These are places where DSL is more popular.

How do I test the speed of DSL?

You can test the speed of your Internet access by going to a website that offers this service. By sending your computer an information packet, which your computer will, in turn, send it back to them. The website will then measure the time it took your computer to download and upload the information packet and calculate the speed of your bandwidth.

This test will measure the ‘actual speed’ and ‘true speed’ of your internet access. Actual speed is the amount of useful data that your connection can transmit or receive per second. On the other hand, true speed also includes non-significant data along with the useful ones. True speed is not used when rating broadband speed rankings. Only actual speed is used for this purpose.

A typical DSL connection will have download speeds of four mbps and upload speeds of six kbps. Cable can offer download speeds of up to eight mbps and upload speeds of 355 kbps.

ADSL Broadband

ADSL is a new technology that stands for Asymmetric Digital Subscriber Line. This product can bring high speed Internet access to homes using standard copper telephone lines. ADSL is widely known as the primary competition to the cable modem, which can give you high speed Internet access using the lines used for cable TV.

There are many advantages ADSL has over cable modems. It is considered to be far less expensive and has a wider range of availability. Unlike cable’s high-speed Internet services, which are only available in high market areas, ADSL is available in places that cable does not offer Internet access. Thus, ADSL might appeal to consumers who prioritize practicality.

What is Broadband?

The term broadband refers to a high-speed method of transmitting data, voice, and video using a wide band of electromagnetic frequencies. This term is commonly associated with Internet access using ADSL or cable. While the term broadband is primarily used while talking about high-speed Internet access, the actual speed threshold of broadband actually varies with the type of connection.

The starting point of broadband is the T1 line, which is widely used in large companies and schools. However, both faster and slower rates have also used broadband.

Technical Specs

Broadband Internet access is much faster than dial-up access. T1 lines have download speeds of up to 1.5 mbps. While cable modems can give you download speeds of up to four times faster than the T1 line, ADSL download speeds will vary on your location and distance to the primary router. It can range from 256 kbps to up to eight mbps.

These types of Internet connections are far superior to what dial-up modems can offer you. Dial-up internet access can only provide you with up to 56 kbps of download speed.

A Review of Popular Audio Conferencing Software Programs

Audio conferencing software normalizes audio, video, and file sharing applications. In other words, this software allows everyone participating in a virtual meeting to see each other hear each other, and work on the same projects together. This last attribute of audio conferencing software is often called collaborative software (formerly known as groupware.) For example, if there is a diagram on the television or computer screen that everyone can see, it is possible for everyone to make marks on the document using a special whiteboard-and-pen program. This brings everyone together in as “real” a way as possible over infinite distances.

Other applications of audio conferencing software include slide shows, streaming audio and video, and document sharing. As telecommunications companies come up with newer and newer ideas, audio conferencing software will have greater and “more real” applications.

When choosing your audio conferencing vendor, the number of users or “seats” could determine which type of technology you’ll need. Some technical support will be needed for all web conferencing solutions.

Three examples of audio conferencing software brands are the following:

Centra

Centra is both a software and a service. The software has all the usual normalizing characteristics, plus a few extras. Centra can be programmed to automatically set up and communicate conference times and dates. It can also track who is logged in during the conference. Afterward, the program can automatically send meetings notes via e-mail to all participants.

Microsoft NetMeeting

Another popular audio conferencing software program, NetMeeting is compatible with any web device. It integrates your calendar, e-mail system, and so on, and is very easy to use. You can even use your web camera to take a snapshot of something and place it on the whiteboard for discussion or markup.

Xbox Live

Even modern video gaming systems use audio conferencing software! You can play a war game against other gamers anywhere else in the world, and talk trash to them at the same time via a headset.

A Review of Air Compressor Manufacturers

It is no surprise that with the increase in demand for high quality air compressors, several manufacturers are continuing to perfect the quality and standards for these devices.

You can find at least a dozen very well-known and respected air compressor manufacturers. Most of these companies adhere to the strict quality and safety standards as set forth by the American Society of Mechanical Engineers (ASME). This governing body is responsible for regulating air compressors and all of their certified products will be labeled accordingly.

One of the most popular air compressor manufacturers in the United States is Sullivan-Palatek, located in Indiana. This company prides itself on creating some of the most advanced engine-driven air compressors on the market, both in terms of quality and safety. These air compressors are among the most energy-efficient available. They also offer used air compressors and air compressor rentals.

Atlas Copco Compressors Inc. is also a very well respected authority in air compressor manufacturing. Located in Massachusetts, Atlas Copco has been in business for several decades. They specialize in both portable and stationary air compressors. Their popular stationary models include lubricated, oil-free, PET, centrifugal air & gas and turbo expanders.

These three companies are just a few examples of the fine air compressor manufacturers located in the United States. With decades of experience, most of the companies that manufacture air compressors are continually striving to make them better. They are in a continual process of advancing features to make air compressors affordable, long lasting, safe, and energy-efficient. When choosing an air compressor manufacturer, you should probably choose one that has been tested and certified by the American Society of Mechanical Engineers (ASME). Many states only allow the sale of devices certified by the organization. This group has set rigorous quality and safety standards that should be applied to most air compressor models.

A Look At Who Has A Hidden Security Camera And Why

Many different types of organizations rely on hidden cameras to bolster their security. Hidden security cameras are appropriate for businesses with many employees and sensitive information or valuable items. They are also appropriate for governmental organizations and families, among other groups.

Many businesses opt for a combination of hidden cameras and visible cameras. The visible ones serve as a deterrent to would be thieves while the hidden ones can monitor the more sophisticated thieves in the event the visible ones are disabled. Banks, casinos and large businesses use a combination of the two types of security camera systems to achieve the maximum desired results.

When employees are stealing, the hidden camera system is the most successful at catching them in the act. Clever thieves will note the angle and ability of the visible cameras especially ones that pan back and forth around a room full of people. Cameras that do this leave blank spots in their field, several seconds perhaps where a particular area is not being photographed. A clever thief will time his nefarious activities to coincide with those blank spots to avoid detection. But if he doesn’t know where the camera is that’s watching him, if he can’t time out a blank spot in the coverage, then he’s more likely to get caught committing his dirty deed. That’s the purpose of the hidden camera.

The infamous “nanny-cam” has caught more than a few nasty nannies, who were ignoring the young children in their charge, or worse, abusing them. The tapes made the rounds of various news programs on TV and a new industry was born. Now there are wireless, battery operated cameras hidden in common household items like radios, and planters that an unsuspecting nanny would never find. As technology improves and electronic items get smaller and better, hidden security cameras will become more readily available than they are today.

A Look at Used Metal Detectors

There are many kinds of metal detectors – gold detectors, coin and jewel detectors, relic hunting detectors, beach-hunting detectors, and underwater metal detectors. Buying a metal detector can be a tricky affair. Before one decides to buy a metal detector, here are a few points to consider.

How often will it be put to use? If it is for a new hobby, it may be a good idea to buy a one with a lot of features.

Where it will be used? Will it be used on the beach, underwater, or in the woods?

Who will use it? If it for use in the family, there are detectors that have adjustable arm cups and separate pouches to mount the electronic box.

How much will you spend on a detector? It is advisable to be a little flexible in this regard so that one can buy one that most suits the requirements.

Buying used metal detectors usually offer the best value for your money. It is always best to buy used metal detectors from a respected dealer, rather than a classified ad. Most dealers offer a money back guarantee or a trade-in option. If you are buying from someone other than a dealer make sure it is someone you know and trust. Most dealers sell only tested metal detectors.

Prices of used metal detectors vary from $275 to $700 for all-purpose metal detectors. Underwater metal detectors can cost around $500. Most used accessories can cost $200. It is also a good idea to keep in mind that a used metal detector will not have the manufacturers warranty, but dealing with a reputable dealer will eliminate some of the risk.

A Look at Laser Toners

Laser toner is the ink for laser printers. It is an extremely fine synthetic powder (usually plastic) packed into a cartridge. You insert the cartridge into your laser printer according to the manufacturer’s instructions. When the printer goes to print a page, there are several steps to the process:

1. The printer receives an image from your computer.

2. Lasers project the image onto an electromagnetic drum.

3. The drum is charged positively and negatively, and at varying levels of charge, according to the image.

4. The drum attracts the four colors of toner in the cartridge according to the charges the colors are attracted to. The four colors mix to create any of millions of colors.

5. The drum rolls the image onto a page of paper, the page goes through a heating device to melt or burn the color onto the page, and the page is ejected.

This process uses up a lot of laser toner. Typically, a laser toner cartridge will yield a few thousand pages before needing to be replaced. The drum, too, eventually wears out from all the positive and negative charges it gives off, and needs to be replaced every 10,000 – 30,000 pages. Some printers are made with cartridge-and-drum replacement units in mind, while other printers are designed to separate the cartridge and drum. This way, when the cartridge runs out of toner, you don’t have to replace the longer lasting drum with it. This saves you money.

You can buy laser toner from your printer’s manufacturer, a computer supply store, online, or at any of a number of other types of retailers. To save money, you might want to consider buying in bulk.

Three of the most popular brands of laser toner are HP, Brother, and Samsung.
