Broadband Internet includes several different ways to receive the Internet and all its capabilities. Broadband can be utilized by different methods of connection. The Broadband is a wider band of transmission of data than what you would get in plain old dial-up connection.

DSL

DSL is actually a type of broadband service that utilizes a broadband connection. There are a number of types of broadband services available to the general public. These services provide much more capability in the transmission of data to your home computer. Dial-up Internet had very little capability to perform more than one task while you were using it.

You have often heard about slow Internet. People with dial-up Internet didn’t realize how slow their digital transmissions were across their phone line. You were really being left behind in the smoke if you still had old dial-up Internet. The dial-up Internet did not have the bandwidth to send data very fast.

Broadband

With the invention of Broadband Internet brought a whole new revolution to surfing the web. A user could do a lot more tasks and also do them at the same time. Broadband has more space to send signals and information over the Internet.

Some people get DSL and Broadband mixed up. When comparing DSL with Broadband you are confusing one of the types of Broadband which is DSL. A DSL cable is actually a type of Broadband service available to customers. There are other forms of Broadband service available to the general public. These forms of Broadband transmission include Fiber-Optic, Cable and Satellite to connect your fast internet service.

How They Work

The DSL form of Broadband transmission uses a certain cable or wire to hook you into the system. DSL stands for Digital Subscriber line. The service is provided or sent over your phone line wire system. It utilizes your existing phone line to transmit the data. You do not need to have any new phone lines installed. There are some places where even with the use of your existing phone line there is sometimes no service available. Even with DSL cable connection with your existing phone you can still use your home phone.

Some people even decide to get rid of there home phone service from the telephone company. They instead choose to use a digital home phone service to receive and make phone calls saving them quite of bit of money over the year. The phone system transmission is sent over the high speed Internet.

DSL is a very fast and economical phone service provided by your local phone provider. The only Internet connection that is faster is the Fiber-Optic form of broadband. This is known to be much faster than DSL but requires the laying of special cable and can take some time to install.

DSL continues to be a good value in internet transmission.

One way and two way anova is a concept that many people struggle with and it’s important to know the difference. ANOVA is that of an analysis of variance. The simple definition is that a one-way will measure the effect of only one factor while a two-way will measure the effect of two factors at the same time.

One Way Anova

The anova test is designed for procedures that violate the normal assumptions. If data is non-parametric and ordinal, then the better test is that of the Kruskal-Wallis analysis of variance.

It all has to do with the experiment and what is trying to be proven. In some instances, it makes more sense for a one way anova test to be run and in other situations, a two way anova should be run.

A one-way anova is going to allow you to assess only one aspect. This could mean the treatment effect or the time effect, for example, but not both. If you only need to assess one aspect, then there is no need to bring in a second factor. Otherwise, it over-complicates what you are trying to prove.

Two Way Anova

The two-way anova is designed for more intricate experiments. It would allow you to assess two factors simultaneously, such as treatment or time. Additionally, it is going to allow you to see if there is some kind of interaction between the parameters. If there is an interaction (or not), it could then demonstrate that more in-depth experiments need to be performed.

How They Perform Assessments

The one-way anova will allow you to compare multiple samples and this is where many people are confused. You can still have the samples, with one of them being the control. However, you are only using one type of sample, one factor. The technique is also only going to generate numerical data. The one way anova will produce an F-statistic.

The two-way anova will assess the main effect of the variable and the interaction. The sums of squares will be calculated in order to determine the significance of the factors.

If you have a null hypothesis that you want to test, you are going to use ANOVA. You can sample with the same mean values and obtain a significant amount of data. Since there are differences between the one way and two way tests, you will have to decide which one is more effective based upon whether you are only testing one factor or not. The samples need to be independent, population variances need to be equal, and you have to be prepared to have at least three or more samples, regardless of what you are testing.

From there, it is up to you as to whether you want to test a single factor or if you want to test a relationship between two factors.

USB cables have been around since the nineties and enable the user to hook up your computer to other devices like a printer or for charging purposes. With a USB cable you can also charge your portable devices like your cell phone or tablet without the use of an outlet.

The USB has become a great adapter also for just about any device you can use on a computer. By using this cable you can play or use about any electronic device that is known to operate from a computer. The word USB stands for Universal Serial Bus. With a computer and it’s hub you can plug in many USB devices at one time. Some have as many as six ports or connections.

USB 2.0 vs USB 3.0

USB cables come in two basic types, USB 2.0 and USB 3.0. The 3.0 is the newest USB cable and arrived on the marketplace around 2009. The USB 3.0 is newer and a lot faster than the 2.0. The USB 3.0 cable has a speed of ten times faster than the original 2.0. The USB 3.0 has a more efficient management system saving you energy.

If you have a USB 2.0 port on your computer you can still use the newer 3.0 cable on it. If you don’t know what kind of port you have on your computer you can find out by looking at the inside of the port. The 3.0 port will be a blue color on the inside. The same for a 3.0 cable it will be blue on the inside. You can still use your USB 2.0 cable on the 3.0 port of your computer. Likewise the compatibility of the USB 3.0 cable will hook up on the 2.0 USB computer port so you have a backwards compatibility.

The newer USB 3.0 cable however provides a faster speed than the 2.0 cable. It is actually much faster up to ten times the speed of the older 2.0 cable. So with all the reverse compatibility of the connections of your devices you will need to purchase a USB 3.0 cable to run at faster speeds.

The USB 3.0 cable has more bandwidth so you can receive more channels including sending and receiving data. This is what makes the 3.0 cable a much faster connection for all your USB devices. To get the top speed for your devices you need a 3.0 USB cable hooked up to a 3.0 port. Your device will have to be USB 3.0 connector also. To sum up; the USB 3.0 cable is much faster than the 2.0 cable but you will need all the 3.0 connections on your computer and your device to get the fastest speed.
