Command Prompt
One of the many preloaded features of your Windows computer that is often bypassed as a low-function program is your command prompt. This is really one of the most powerful programs on your computer. With many capabilities, and a semi-easy interface, this is something you should always know how to use. This can usually be found in your computer under the start menu, all programs and accessories. Once you open the program, the best way to get started is to type in what you may be feeling, help. This will open a list of a lot of commands. These are not all of them! There are many more useful ones that are not listed. A couple very useful ones (In my opinion) that are not listed are ipconfig, which shows lots of information about your internet connection. You can also use it to run programs by typing in the program name when you are in the correct directory. I would recommend checking it out, because it is quite powerful, and is used by many programs. Explore the commands, and try to learn some things, it will help you to understand your computer much more. Note: You can create an automatically running program with command prompt by creating a new text document, entering command prompt commands in the file, and save. Then rename the file extension (The .txt part) to .bat. There should be a window popping up saying that if you change the extension the application might become unusable, you want to say yes.
HTML Coding Without Additional Software
HTML coding is the stuff that makes up websites. Every website that you come across is coded in HTML. Below is a video about how to program in HTML on your computer without any additional software. Enjoy!
E-Ink Technology
Jan 22, 2012
If you have heard of the new 'novelty' idea for reading, the e-reader, you may have also heard about its notoriously long battery life of two months. You may have also wondered how it lasts that long. The secret is in the E-Ink display. This display is unique because it isn't necessarily a screen. It is like looking at a piece of paper. The screen is very unique, and a fabulous technology. The screen does not require any power at all, and it only takes battery to flip the page or change the screen. The way the screen works is there are a ton of pixels, and these pixels can be one color. Today you will only find black and white, however that is sure to change in the future. Each individual pixel can be changed from black to white by applying a certain voltaic factor to it, or in other words, putting a very small amount of positive or negative voltage through each pixel. By doing this, you change the pixels from black to white. The pixels then stay that way until changed again. There is no backlight, just like looking at a sheet of paper. This way, the battery is only used very little, only when updating the screen. This way, when in standy, an image can remain on the screen by using no battery power at all, unless the wireless is on. Same for reading. E-Ink displays are a very helpful technology, especially because you have no harm to your eyes. It is a technology that, in my opinion, will rekindle the love of reading in many people.

A Little Bit of Blu Ray
DVD and Blu-Ray
Jan 2, 2012
Video has taken many leaps, and blu ray is not one to be overlooked. The first device that really brought videos to home was the VCR tape. Then came DVD in 1997, and now Blu Ray, introduced in 2006. Blu Ray is not really that different from a dvd at first glance. They are both discs about the same size, and both thin and like CDs. The main difference is in size. The single layer DVD can hold up to 4.7 GB, whereas a single layer Blu Ray disc can hold up to 27 GB. Blu Ray single layer can hold almost six times as much as a DVD can. The DVD can hold plenty for an average length two hour standard definition movie, and a few movie extras, like animated shorts and other bonus features. This is where the problem comes in for DVD. Now that there has been more high definition movies come out, there has been less and less room on DVD. The Blu Ray can solve that problem. With way more space, it holds plenty for a high definition movie and lots of extras. The way a blu ray disc holds more is in a thinner area for the actual data storage area. Then you are able to put more layers of bumps and dashes, providing more information. The disc itself looks the same, but it will not work in a DVD drive or CD drive. Blu ray has had a slow adoption rate, however I believe it shall soon become the standard. Please note that this is just a brief overview of blu ray.

Christmas Lights, Series Circuits
Christmas Lights
Dec 7, 2011
The Christmas season wouldn't quite be the same without Christmas lights decorating the homes of many. These are used to decorate Christmas trees, outside of houses and many other large structures. This technology is rather simple, just lightbulbs and wires. However, some of you may have had the unfortunate problem of having one of your bulbs burn out. This then brings on the painstaking task of testing every light slot for a burnt out bulb. This process is difficult and annoying. It isn't that simple to just plug it in even if a light is burned out, because if one is burned out, the whole circuit won't light. This is because Christmas lights have series circuits. Series circuits work by connecting the negative end of the power source to the first electronic component, then from that electronic component to the next. This continues until the electricity reaches the end of its journey at the positive end of the power source. When the power reaches a component that is not functioning, the power than cannot travel to the next component, and therefore, not to the positive end of the power source. This causes the whole circuit not to work, because the electricity cannot flow. This problem can only be repaired when you replace the disfunctional electronic component. Other than this minor problem, Christmas lights are an excellent and festive holiday decoration.

Pandora Radio
December 6, 2011
Pandora radio is something you probably have heard of. To sum it up in a sentence, it is a free online service provided to those who have signed up to Pandora that provides them with the ability to make 'radio' stations for an artist, genre or song. This service I have found very useful and a great online service that you should definitely take advantage of.
To explain Pandora, it's best to start at the beginning. When you first go to Pandora.com, the homepage for pandora, it asks if you would like to create an account with Pandora. It asks for the typical information, your email and a password. (For ways to make a safer password, view my article in web safety about safe passwords.) Once you create this, you have opened a Pandora account and have the ability to create radio stations for your account.
The 'radio' stations are created from an artist, genre or song. The item you created your radio station for then finds songs by that artist or songs similar to this and plays them on the radio station. Pandora radio finds songs similar to the artist or songs from the Music Genome Project. This was a project for classifying music in to catergories, and then it compares it to other songs and categorizes them. This project continues today, and classifies the newest songs. You have the ability to 'Thumbs Up' the track or give it a 'Thumbs Down'. This is done by selecting either the thumbs up or thumbs down on the screen. When you give it a thumbs up, you are essentially telling the radio station that you like it, and Pandora will then incorporate songs similar to that one on that certain radio station to be played on that station. When you thumbs down a track, it then skips the track and avoids songs similar to that one.
Sometimes when you thumbs down a song, however, Pandora will continue to play that song instead of skipping it. This is because the music licenses of Pandora force the account to limit the number of skips you have. There are also many ads on Pandora, and this is so Pandora still generates revenue from this service. You also have the option to upgrade to Pandora One for $36 a month. This enables no ads, a specific desktop program for streaming Pandora, and other personalization services.
Overall, Pandora internet radio is a very innovative and useful service. To visit Pandora on the web, click here.

The Parts of a Computer
Parts of a Computer (Click for Larger Image)
Nov 23, 2011
The computer is one of the most useful and popular ways to do buisness, enjoy media and connect with people all over the world. What makes the computer run? This article will run through the parts of a computer.
First, lets start with the part that stores the information. This is called the hard drive. This is a little rectangular box that contains several silver discs. These discs are containing all of the information that runs a computer. There is a little bar that writes the information for each disc. These discs are double sided, providing the hard drive with more storage. When you save a file on a computer, this is where it is. This is a crucial component to a computer.
Another crucial component that a computer needs to run is the processor. This is the device that allows the computer to execute processes. This processor is needed for everything on a computer from starting up to shutting down. Almost every electronic device has one of these. Depending on the device, the processor can be more or less powerful. For a digital watch, it is a very low power processor. For computers, the processor is much higher. There are multiple types of processors, such as a graphics processor and CPU, the Central Processing Unit.
The motherboard is another essential component of a computer. This contains several important components, like the processors and hard drives. It also takes care of linking everything together and sending it out to the monitor.
There are several other components that I will not be able to cover, but some more you should know are the USB connectors, the monitor output, the speaker output, network connections, computer fan, CD and DVD drives. There are many more components, and I hope to write another article about them in the future.

CD
The CD
Nov 20, 2011
CD, or Compact Disc, has been around for many years, and over the years, has had several uses. Mostly for music, but still used for storing computer files and videos. As the longer the CD has been around, the more useage it has gotten. Now that we have begun to live more in a digital age, the CD is going away. Streaming and buying mp3 files or mp4 files off the iTunes, Amazon.com or other music download services has become much more popular. With the increase of portable media players, this has also caused the steady decrease of use of the CD. Before this technology is completely gone, it is something to understand.
Compact Discs are named rather appropriatley. They are discs that have many things compacted inside of its four layers. The top layer of a CD is the Protective Layer. On top of the protective layer is the printed label. This protective layer is the thickest part of the CD. Directly beneath the protective layer is an aluminum layer, you will see why this is necessary. Next comes the Plastic Data Layer. This is the layer that contains the information on the CD. Beneath the plastic data layer is a transparent layer. The plastic data layer is the area that holds all of the information. Like all digital devices, the information is in ones and zeros. Of course, it is not on the CD this way. It is on the CD in tiny bumps. These bumps are representing the ones and zeros. There are two types of bumps, long and short.
Compact Discs are read through a very interesting and innovative process. When you place a CD in a CD Drive or a CD reader of some sort, you either insert it through a slot, where it then is placed on a motor somehow, or you place it directly on the motor yourself. If you have the opportunity to look at a CD drive where you place the CD directly on the motor, you will most likely be able to see the laser. This is a little glass lens that moves up and down or side to side, depending on which angle your are looking at it. It is important that you do not touch the glass lens, because this will interfere with the devices ability to read the CD. Beneath this lens is a prism, that has a laser pointing at one end, and a sensor at the other. The laser is a weak laser, it cannot hurt you, and you can't see the laser. It is a frequency in the light spectrum that our eyes cannot detect. When the laser hits the prism, it is then directed upwards, and hits the CD on the transparent layer. The motor spins the whole time for this process, and the laser is hitting the plastic bumps, and the light is absorbed in the bumps, but when it hits the breaks between the bumps, it hits the aluminum, which then reflects back to the prism, angling off and going to the sensor. The sensor sends the information to a electronic component that takes the time in between each time the laser hit the sensor, and turns that in to ones and zeros, and the device then reads the ones and zeros and either plays the audio, video, or shows you the file. The CD reads this information, and it continues in a spiral until it reaches the end of the CD. Compact Discs can store up to 80 minutes of WAV file audio, or uncompressed audio. Or it can store up to 700 MB of data. DVD, or Digital Video Discs are read in a very similar way, just with smaller bumps, and a thinner laser that is more exact.
The CD is a technology that has served humanity well, and continues to do so. For over 30 years, CD's have been used by people all over the world.

WiFi
WiFi, connecting all types of devices
Nov 13, 2011
There have been several developments of technology using radio, and this is another one. WiFi is a gadget connecting all sorts of devices together providing them with access to a network or the internet. WiFi is used all over the place. You can find it at homes, restaraunts, hotels, airports, pretty much anywhere. There are even certain cars with wifi routers. The most recent development with wifi is the MiFi mobile wifi hotspot. This is a wifi router that is battery powered, connected to a 3G or 4G network. So, wifi is a technology that uses radio. Just like a two way radio, a device connects to the wifi radio frequencies. This is a technology all in its own. Most wifi networks have network keys, either WAP or WEP keys. These passwords are a series of numbers and digits. If you type in the correct passcode once, your device will remember it and send it to the wifi router every time you connect to it, and then you can access whatever that wifi router provides you with.
There are several things a wifi router can provide you with. It can bring you access to the different devices that are connected to the same wifi network. For instance, you can transfer files from a mobile device to a printer, or a laptop to a printer. They can also provide you with a VPN, virtual private network, a network where you can store files and share them through a central system. Businesses and schools are common users of this type of wifi. The most common thing a wifi network provides you with is internet access. Your device connects to the network, you type in a website address, and the wifi finds the address and transfers the information over to your device via radio. There are several other uses for wifi networks, it is not just limited to those three.
The devices that use wifi are very numerous. Anything that comes out in the modern technology that would require internet access probably has wifi connectivity. Because of its increasing popularity and because it is becoming increasingly widespread, it is the most common way for devices to connect to the internet aside from cell phone networks, like AT&T or Verizon Wireless. Everything from iPods to gaming systems to laptops and tablet computers.

Radio
Radio: Then to Now
Nov 9, 2011
From all the way back to the eighteen hudreds to this year, radio has been popular. But what you call radio is more than you may think. Let's start at the beginning. The first version of radio was a wireless telegraph. These were used as methods of communication using morse code. From there radio has improved in to what we would consider radio now. From simple AM stations, then moving on to FM Stereo.
The way the radio actually works is pretty cool. What you have in a radio is a transmitting tower. This tower takes audio files and turns it in to electromagnetic waves. These waves are alternating in different ways to then be played back through the radio receiver as audio that was spoken back at the radio transmitter. This is still what happens today, as back in the nineteen hundreds. When you try to find a specific channel, you select through either a bunch of numbers in the hundreds, or numbers that are decimals. These represent the different frequencies that the certain radio station broadcasts at. These frequencies are in megahertz, represented by MHZ. For a radio station, you might find 94.3 as a station, and that would be broadcasting at 94.3 megahertz in the electromagnetic spectrum. On the AM stations, however, you will get numbers in the hundreds. This is because they broadcast at a much lower frequency than the FM stereos. The newest form of radio is the HD radio, which operates on these electromagnetic spectrums, but uses more frequencies for one station. This frequency has a much higher quality audio then the others, as you can tell from its name.
There is also two way radio, a similar form of communication, using different frequencies in the electromagnetic spectrum. This works by transmitting your voice over to the receiver on the same channel, and then the other person can respond to you using the same method. There are many, many other devices that use radio waves that you may not realize it, and I hope to make future articles about these devices. In conclusion, radio is a technology that changed our lives in many, many ways, and is continuing to do that even today.

Cool Key Shortcuts
Nov 3, 2011
When you use a computer, one of the easiest ways to navigate around is the mouse. You can do pretty much anything with a mouse. When you use your mouse, there is an easier way to do pretty much everything you do with the mouse. These are called key shortcuts. The key shortcuts are easy to use once you get the hang of them, and can make life on the computer faster and easier. There are also a whole lot of other websites that list different key shortcuts. Once you learn to practice them, then using a computer can become a whole lot easier.
Computer Key Shortcuts
