COMPARISON OF USING A SKYPE AND USING A CELL PHONE:
I have selected to compare Skype and cell phone. Skype is an Internet program. If you want to use it, you need to be registered. To talk on Skype you must use microphone and earphone. But cell phone is an aparate which is used for talking and sending messages. If signal is out, you can not talk. You must pay every minute of your talking.
