A common cellular phone is composed of a keyboard, a small screen, and a battery. There are two types of Keyboard: half and complete. The half keyboard is when the cellphone has only the numbers in the keyboard. But, if it has the all (the) letters, the cellphone has a complete keyboard. Also, there are two types of screen: the normal screen and touch screen. The normal screen only project(projects) the image and you make all the moves in the keyboard. The touch screen now is more popular than the normal screen because you can touch the screen and make the moves that you want to do with your finger over the screen. And obviously the battery is the font(source) of power of the cellphone; it gives the energy to use the cellular phone. In summary, a cellular phone is designed with the keyboard, screen, and the battery is designed your cellular phone.
