What’s
the differences between CDMA (Code Division Multiple Access)
& GSM (Global System for
Mobile
Communication) ?
The only differences are the way by which voice gets
carried from one phone to the other. CDMA assembles multiple
voices into the same frequency, & also increases voice
clarity. The technology also helps you receive calls when the
signal is weak & thus it doesn't have the problems like
Call Failed or Fading during high traffic density.
This also gives CDMA service providers the flexibility
to provide data & video service.
CDMA was invented during World War 2 when Allied forces
wanted to get past the Germans by sending coded messages over
different frequencies & giving them the ability to be
accessed from different points-hence
"Code Division Multiple Access."
Presently CDMA mobiles are available with Reliance,
TATA Indicom, Hyundia Infocom

Blue Laser
Technology For "PAPER DISC"
Back to paper, Technology getting environment friendly..
Automation & mechanization in the last 2 centuries has seen our race playing havoc with the environment. Its therefore, rather welcome change to see
companies dealing with Technology going the environmentally friendly way.
Previously German & Swedish tie-up that's into producing computer system made up of wood & stones. & Now Its Time for SONY Corp - who are developing a new optical disk that is made of 70% paper!
This new optical disk will be compatible with the next generation of DVD & is based on a version of Blue laser technology called BLU-RAY. Using Blu-ray, a disc can store upto 5 times more data than disc using the current RED-LASER DVD technology. Therefore this new disc will be capable of storage capacity that's close to 25GB!
Experts says that though it can handle high-density data with good security features & can be destroyed easily after usage even by cutting it out with
scissors , BUT There is a risk of the disc being spoiled by moisture OR it may even become your tissue paper by your own sweaty
palms.
