MP3

Invented in 1991, MPEG (Motion Picture Experts Group) Layer 3 – file type better known under the name of mp3 – remarked itself in less than 10 months from the launch as the most performing audio format on the web. And it is no wonder: the sound is excellent, Downloads are fats, and the variety of the products available in this format is overwhelming. The huge competition in the online audio war between Real Audio and Shock Wave produced by Macromedia has been step over at once by the new comer.

Mp3 is digital form of compression audio streams that came to life after 15 years of acoustic research. Mp3 can make an audio file up to 12 times smaller than the original file.
Being so small the mp3file still has all the perceptible audio details, giving up only those that the human ear cannot hear.

According to the declaration of engineers from the Fraunhoffer Institute, a pioneer company in the mp3 technology, this system explores the properties of the human ear, trying to maintain the original sound quality, in the boundaries of what is possible. Although it is not as clear as an audio CD, an mp3 still is an enormous realization when it comes to sound quality for such a big compression rate.

Another huge advantage the mp3 format represents is the stocking capacity. Five minutes of music on a CD take up about 40 MB, but if they were in mp3 format they could take only 3, 5 MB.

For some, the Mp3s are a dream come true, for others the worst nightmare. In the confusion caused by technological revolution, we still cannot afford not to know what is legal and what is not. Recording companies have suffered great losses because of this format.

It is very simple to create and distribute mp3s. But this does not mean you have to give them to others unless you have the right to do that. It is legal to make mp3s out of an audio CD you bought, but it is illegal to give someone copies of those mp3s.

CELL PHONES

The amazing technology cell phones have these days is surprisingly growing and developing.

Cell phones started out as an idea for a mobile phone that can be used from a car, within a given range. This was happening back in 1947. Since then, their purpose was achieved and greatly exceeded.

The mane comes from the word cellular combined with the normally used word, phone. Cellular because their whole technology is based on cells of signal. Each cell has as a centre a transmitter that assures the mobility and the great range, almost worldwide, of mobile phones. These transmitters are placed in such a way so that they can form a network with absolutely no uncovered spaces. Not all portions have been covered, but the civilized and populated locations all have mobile phone operators and coverage.

Nowadays, mobile phones try to include as many technological areas as possible. There is no cell phone out there that is only a cell phone. From watching TV to playing games, taking pictures and making movies, from real music to color display, they have it all. Some phones even have Windows from mobile on them, just like PCs. Others can actually compete with game consoles like Nintendo because they are kind of a miniature game console themselves.

The extreme competition out there makes developers want to achieve more and more with their phones. Japan has always been a pioneer in the cell phone industry, they had TV and camera phones long before they appeared in America and Europe. Japanese manufactures and worldwide producers try every day to come up with new things for a cell phone, following a fixed goal: the perfect phone that can stand for all multimedia and communication devices out here, a phone that combines everything from communication to utility and work.

So, in the near future the cell phone might offer us a great surprise. How knows, they may try and develop some kind of holographic graphics. No matter what the next step is, the industry is certainly improving every minute, even as we speak and cell phones have a bright future ahead of them.

ADWARE AND SPYWARE

Adware is any software application software which makes banners appear the whole time it is in function. Also, the adware program can install components that will transmit information about the user and its behavior and this work on his PC. Unlike spyware programs, the user is asked when the program is being installed. Actually, an adware application is the application that, along with its basic functionality, has a different one, the one that makes it show commercials once in a while, downloaded periodically from certain internet servers.

Spyware is a program, usually downloaded from the internet, which sends information about the user without him knowing it, every time he connects to the internet. Usually, the packages sent contain marketing information and not confidential information, although some programs can do that too.

Even if some applications are both adware and spyware, this is not a generally true situation. Most of the times spyware applications have installed themselves and they are working without the user knowing it, opposing the adware applications that cannot be installed without the consent of the user.

For a long time quality and free software was installed and used for free but once the complexity of the programs became greater their costs have risen till the point the developers just had to find out methods to diminuate them. One of the easiest ways was delivering along with their programs application like adware and spyware. On the other hand, many commercial programs became usable freely and legally by passing the line to the adware category.

From the harmless intention of showing some commercials and till elements of analyzing and stocking information about the user and his software or hardware configuration the developers had to install on the target computer supplementary modules. If at the beginning it was only an engine that downloaded commercials and showed them in pre-calculated windows, the adware industry has evolved and grew a great bit since then. Now they use different instruments, from altering your browser and its settings and till launching background applications that monitor your PC activity.

Among the effects that follow installing spyware and adware are the next ones:
- Adding links to various magazines
- Adding new commercials on the web pages, sometimes replacing the existent ones
- Monitoring browser behavior in commercial purposes.
- Gaining access to passwords and credit cards.
- Slowing down the computer.
- In some cases they can call telephone numbers with high costs.
- Changing the browser’s homepage in commercial purposes.
- Strange icons and new software might appear on the desktop.You can enter their online
sites and try the services for free, then decide what to use.
