Technology Analog VS Digital Technology

Entering into the 21st century, the development of science and technology (science) is quite fast now has become the daily reality is even the public demands that can not be negotiable. Something that seemed impossible in the past, into something real now. For instance a computer, three-dimensional television, and others. Right now all the sophisticated equipment we enjoy. Technological advances really make our lives easier.

All that can happen because of the people called scientists who discovered the technology is advanced technology. They seek information and learn with very detailed information that can fulfill their dreams that we can now finally enjoy, technology. Technological developments also bring new things, namely the communication revolution. This is because, the development of technology that can be said is the fastest development in the field of communication. Inventions such as telephones, fax machines, cellular phones, scanners, etc. are the tools that help create the relationship easier communication between human sesame.

The technology now is really growing rapidly. Due to the analog world that we run now, we continue to demand more difficult seems to have fulfilled by analogue technology to digital technology was developed. Digital technology in communications is very important.

Previously need to be understood, the technology is the process of sending analog signals in the form of waves. For example when someone is communicating with the phone, the sound transmitted through the telephone network is passed through the waves. And then, when this wave is received, then the wave tersebutlah translated back into sound shape, so that the recipient can listen to what is delivered by other speakers of these communications. The phone that since the beginning, is one of the analog implementation, as well as in the case of radio and television broadcasting. Now beginning to change towards the digital system is more sophisticated, fast and efficient.

Digital technology is the process of sending data in the form of two symbols, namely on and off. Identical to the socket. By using this digital, information passed is a throbbing mix of electricity on and off. This combination is translated into data. This technology is commonly used in advanced technology. Example of a very simple is in terms of computer usage, and so on for data processing done by computers.

The advantages of this digital technology is its ability to process data in the communication traffic is dense. As for analog, is used for low lalulintasnya communication. While signals in digital form capable of sending data much faster with a larger capacity, and has a small error rate, when compared with analog signals.

In the field of communications, digital technology developed by using the elektomagnetik spectrum is a combination of magnetic frequency, radio waves, X rays, cosmic waves, infrared, light, radio waves and microwaves. That's how television, radio, computers, etc. can be created.

Digital technology also must be very worried if the device has an error, because from there the possibility for damage is enormous. In addition to the existence of digital technology, trend for people to forget the enormous analog technology. Therefore, the findings are very significant once, now do not dominate. Coupled with large-scale promotion of digital technology that makes people willing to invest heavily. It is not good because they are not necessarily the investment is a good thing and useful for everyone.

Therefore, to avoid all that and be able to use digital communications technology to the maximum, we must know the function of these technologies. We can not accept and wear the origin of each new technology. We must realize our need, do not easily washed evolving technology every day. For that, again here is very selective attitude is required.
