Listen to the text about mobile phones and complete it with the words from the list below. https://el.istu.edu/pluginfile.php/302932/question/questiontext/3039688/4/415247/ELI_FLASH%20FOR%20MECHANICS_TR08%20%28mp3cut.net%29.mp3 A пустоcellular phone (or mobile phone) is designed to give the пустоuser freedom of пустоmovement while using a telephone. It uses radio пустоsignals to communicate between
the phone and the пустоantenna . The server пустоarea is divided into smaller areas called пустоcells and an antenna is пустоplaced within each пустоcell and connected by telephone пустоlines . These lines connect пустоcellular phones to one another: a computer пустоselects the пустоantenna closest to the telephone when a пустоcell is made. If the phone moves to
one serving пустоcell to another, the radio signal is пустоtransferred to the actual пустоcell without interrupting the пустоconversation .
The пустоcircuit board is the heart of the system. A пустоchip translates the outgoing and
incoming пустоsignals from пустоanalogue to digital and back from digital to пустоanalogue .
The microprocessor пустоhandles all the functions for the пустоkeyboard , the display and
the loudspeakers, and it пустоcontrols the signal to the base station. Other flash
memory chips provide storage for the operating system.
A
пустоcellular phone is not only a phone but it provides an пустоincredible amount of
functions:
• пустоstore information;
•
use a calculator;
•
send and пустоreceive emails;
• пустоsurf the Internet;
•
play simple games;
•
play music, take photos and videos.
Can
you пустоimagine your life without your mobile phone?
