How does a fiber optic cable carry telephone conversations?
We're used to the idea of information travelling in different ways. When we speak into a landline telephone, a wire cable carries the sounds from our voice into a socket in the wall, where another cable takes it to the local telephone exchange. Cellphones work a different way: they send and receive information using invisible radio waves-a technology called wireless because it uses no cables. Fiber optics works a third way. It sends information coded in a beam of light down a glass or plastic pipe. It was originally developed for endoscopes in the 1950s to help doctors see inside the human body without having to cut it open first. In the 1960s, engineers found a way of using the same technology to transmit telephone calls at the speed of light (186,000 miles or 300,000 km per second).
Where can one find a broadband speed tester online?
"The internet company that you use should have a speed checker that you can stream on their website. I have Windstream, and I know they have one."
What does download speed of 8Mb mean?
8Mb is a form of speed. First off as a note, a single Byte is equal to eight Bites, which is why advertisements for Broadband companies like to use the Bites since it makes the number seem much higher. MB = MegaByte
Mb = MegaBit The capatalization of the B/b is very important as you see. Now one MegaByte is equal to 1000KB (Kilobyte), same rule works here with the capital B/b. One megabit equals to 125 KB (where 8 Mb = 1 MB)
Now for most small screen movies (youtube, etc) to play smoothly without breaking up takes about a steady 250-350KB/ps (per second). Speeds are not always constant since when trying to download it might sometimes come from a host in another country. In which case it has to be redirected through several countries and servers before the file reaches your computer. To see this in action, do the following: In Windows, select Start > Programs > Accessories > Command Prompt. Enter the word tracert, followed by a space, then the domain name (i.e.- www.msn.com) http://www.mediacollege.com/internet/troubleshooter/traceroute.html

How does bandwidth affect internet?
How Does Bandwidth Affect Website Performance?
by Jamie M
One of the most crucial aspects of a website's performance is the amount of bandwidth allocated to its use. Bandwidth determines how quickly the Web server is able to upload requested information. While there are other factors to consider regarding a website's performance, bandwidth is frequently the limiting factor.
BANDWIDTH DEFINITION
Bandwidth is defined in terms of number of bits per second. A bit is the smallest amount of computer information, a zero or one, and eight of them make a single byte.
Historically, network connections are measured in bits, while end-user devices such as computer memory and hard drives are measured in bytes.
A megabit is just over a million bits (more precisely, 1,048,576 bits), while a gigabit is over a billion bits (precisely 1,073,741,824 bits).
Therefore, a 100-megabit-per-second connection can send over 104 million bits per second, which is more usefully phrased as 13MB per second.
CALCULATING BANDWIDTH REQUIREMENTS
Most Web servers send static pages and images upon request to Web browsers, which means that no modification is necessary to these files before they're uploaded over the Internet.
In these cases, bandwidth requirements are fairly straightforward.
Add up the total number of bytes used by the resources that make up a particular page on your site: an HTML page is a certain number of kilobytes of HTML, JavaScript and included files, while the images the page requests will probably be a larger number of kilobytes. For example, a homepage may be 25KB of HTML, Cascading Style Sheets and JavaScript, which then makes requests for 250KB of images. Therefore, requesting this page for the first time you'd need 275KB of data, or 2,200 kilobits. Over a 100-megabit Internet connection, you would use just over a quarter of one megabit for one second, which roughly works out to 300 simultaneous users being able to access the site without slowing down. Some amount of bandwidth is always lost to overhead networking requirements, so rounding down these estimates (in this case, from 364 to 300) is a good idea. Websites that expect more than 300 simultaneous users, therefore, would need more Internet bandwidth, or use smaller files on their homepages.
CPU BOTTLENECKING
A website can also be slowed down by the need to serve dynamic files. This is the case whenever a Web page is generated based on programming code; for example, pages on a WordPress site are not static HTML but are generated upon request by PHP programming in the WordPress template. A dynamic site with the same parameters as the static page example would be able to handle only 300 simultaneous users if the CPU requirements to generate each page are roughly under one-third of 1 percent of the CPU. On the other hand, if 1 percent of the CPU is used to generate a page, then the maximum number of simultaneous users will be closer to 100 than 300, even though its available bandwidth can handle more users.
CACHING AND CONTENT DELIVERY NETWORKS
Bandwidth bottlenecking can be improved by using content delivery networks, or CDNs, which store copies of your Web server's data, usually at multiple points across the Internet. For example, a CDN may be located in Tokyo and London, duplicating -- or caching -- information from your Web server for users in Asia and Europe respectively. The CDN is physically closer to the user, speeding up delivery and reducing the number of hits on your primary Web server. Likewise, caching on the local Web server or CDNs can also greatly reduce CPU requirements, but at the cost of sending slightly out-of-date pages to Web browsers.

You can upload/download (or whatever it is talking about) .5 mb more per second. 2mbps stands for 2 megabytes per second. 1.5mbps stands for 1.5 megabytes per second.
What are typical download speeds for wireless high speed internet?
A average internet speed is around 3-4mb in the UK. This may apply to the US and other counties also. As you may know, there are better internet connections out there which will give you 20, 30, 50, even 100 mb but this is not yet popular.
Can laptops use wireless home broadband?
If a wireless adapter is attached to it, then it should. However, many desktop computers will not accept wireless internet without the adapter, simply due to the point that it is somewhat unnecessary as a desktop is not easily portable.

Do you need long distance service for DSL?
Yes, if the fax is being sent to a long distance number. You dial a fax number on a fax machine exactly the same way that you would dial the same telephone number on a landline telephone at the same location. If the phone line you have the fax machine connected to cannot call long distance, then the fax machine will not be able to send a fax to a number outside your local calling area.

How do routers affect internet connection speed?
There is a little trick you can do with ISP modems you see your ISP (Internet service provider limits the speed of your connection this works for some routers depends on your ISP if you are not familiar with the configuration of setting up your modem don't do this as you will be doing something that is called hard resetting of the router when you do this your router will forget all configurations it had previously so you would have to know how to set it again
OK get your router hold down the reset button at the back for 30s while doing this unplug the power to the router keep holding down the reset button for another 30s so after 60s you will be plugging the power back on while holding the reset button for another 30s so that's a total of 90s that you held down the reset button for voila done if you are unsure how to set it back up make sure you have someone there to help you with this.
