Abstract: The basic principle of this invention is to add a suitable audio compression software to cellular and home phone sets to adjust the sound quality and reduce sound memory, thus for instance, a person may speak for ten minutes into the microphone of a cellular or home phone and his/her speech will be compressed to a 350 KB file to be saved on the phone memory, then by calling a cellular or home number possessing the same feature the file will be transmitted within seconds and received by the recipient even if the phone is switched off, as the duration of transmission is very short, the monetary cost of sending a file will be extremely low, the cost of sending a ten minutes voice message will drop to 1% of its actual cost as well as adding an answering machine feature to these sets.

Abstract: This invention protects the data on the hard disk from viruses and hackers by making it possible to turn off any head whether it is a read head or a write head of any arm of the hard disk by providing switches, so when we surf the Internet we turn off the read/write heads of the platter surface which contains the confidential data and we always turn off the write head of the platter surface which contains the Windows programs and other program files so the programs data are always protected and at the same time it is always readable, after we logoff the Internet we turn off the read/write heads of the platter surface used to save Internet data onto it thus we will never have any virus moving from this platter surface to the rest of the hard disk platters surfaces.
