Short message service (SMS) is a wildly popular feature available on most digital mobile phones. SMS allows users to send short messages to other cell phones. These short messages are called text messages. SMS was invented by a Finnish civil servant named Matti Makkonen. Many people understand what SMS is, but few understand how it actually works.

In SMS, messages are sent with a “store-and-forward” mechanism. The messages are sent to a Short Message Service Center (SMSC), and then relayed to the intended recipient. If the messages do not reach the recipient upon the first attempt, then the SMSC will try again. It is important to understand that SMS delivery is not guaranteed. Many messages cannot be delivered, but the delivery is called “best effort.” The amount of attempts to send a text message varies with the company.

SMS messages are transmitted via SS7 within the standard GSM MAP framework. SMS messages have a certain payload length. The signaling protocol is precisely 140 bytes. In simple terms, SMS messages have very constrained character limits. This is why messages are sent in “txt speak.” Text speak is the practice of shortening words and phrases in order to fit messages into the allowed amount of bandwidth. SMS messages cost different amounts in different countries. In the United States, the average message costs 10 cents.

Text messages do not always have to be sent from mobile phone to mobile phone. AOL Instant Messenger has an option that will send instant messages to a cell phone. Additionally, there is a widget available for Mac OS X Tiger that will allow a user to send text messages to a cell phone from the dashboard. SMS messages can also be utilized to give news alerts. Additionally, SMS messages can be used to give sports updates and statistics. In this way, SMS messages are very versatile.

Technology is constantly evolving. SMS services prove that communication is becoming broader and easier. Technologists predict that SMS service will advance such that the service will be more reliable, and be able to store more data for the purpose of transmission.

Capturing Your Wedding On VideoToday professional videographers have become as natural a part of the wedding as the photographer. Because your wedding day goes by so quickly, recording all of the activities on video will preserve the precious moments for you and your family to enjoy for years to come.

Unlike photographs, a video camera records sounds, action and more of the overall atmosphere of the event. Rather than focusing on just a few people like photographs, video can easily record a little bit of all of your guests.

The typical wedding video package costs anywhere between $500 and $1500, depending on the quality of the equipment, the number of hours of coverage, the number of cameras, the amount of editing, and other factors. As always, remember what's most important to you, determine what you can afford, and go from there.

Recording Your Wedding on a Tight Budget
If you don't have money in the budget for a professional videographer, you have other options. You could ask a close friend or family member with a video camera to record your wedding. Of course don't expect the same quality and coverage that you would get from a professional videographer. Remember, is an awful lot to ask friend or family member to tape the bulk of the wedding day. So, the best way to ensure that your most precious moments get recorded is to make a list. Pick out only a handful of moments that you definitely want on tape, such as the bride walking down the aisle, exchanging vows and rings during the ceremony, the best man's toast, the bride and groom's first dance, etc. Then anything extra that gets on film is a bonus, but you have the important stuff covered.

Special Touches for the Video
A nice touch for your wedding video is to have your videographer or a friend wielding a video camera pull your guests aside throughout the night to record a personal message to the bride and groom. This is something that a friend did for us at our wedding, and it was absolutely wonderful to watch. This is a lovely way to record all of your friends and family who attended your wedding and adds a personal touch to the video.

Another nice idea for the wedding video is to record a short message from the bride and groom to each other. Arrange for the videographer to meet with the bride and groom separately right before the wedding ceremony. Each can talk to the camera as if they were talking to their soon-to-be other half. These messages truly capture all of the love and emotion of the couple on their wedding day. And they are so much fun to watch after the wedding and many years down the road!
