Mobile Phone LOI 2
Digital communication also allows for more secure phone calls and conversations as people can't listen to them using a scanner. if we use digital communication, then we can communicate from anywhere in the world as it uses satellites to transmit the signals from our phone's antenna. A subscriber module identity card (aka sim card) is used. Earlier it was as big as a credit card and a microchip which allowed access to the satellite which transmits the radio signal that the phone sent.
Microprocessor - All digital devices have an IC that processes programs - and also some instructions make the device work
Transistors are found in integrated circuits. These are made from pure silicon. The current flow through the transistors from the term “Source” to “Drain” but only if there is an electric field applied called “gate”
When a phone number is tapped into the keys of a telephone, it sends a series of electrical signals along the telephone network to an exchange.

All smartphones have a camera but most of them have a digital camera with zoom feature and recording feature
-
Analogue to Digital - The analogue-to-digital chip takes the information from the real world and then it converts it to binary codes numbers.

Before smartphones, there were telephone booths.
-
When a message is sent, it travels as codes of radio waves into the nearest cell phone tower and transfers it to the next person's phone.

phones were converted into smartphones. Smartphones also allow us to do many things, not only phone calls but smartphones are like computers.
The way a chip works is the result of how a chip’s transistors and gates are designed and the ultimate use of the chip.
-
There are 3 colours in a pixel red, blue and green
-
When there's an incoming call, the computer sends it to the area that contains the correct phone, making it ring.

Flash Memory Chip - FMC is found in USB storage, digital camera, and solid-state hard drives, flash chips can store much information.

-
Your electronic cracks when it is cloudy or rainy because the satellite radio waves are blocked and can't get through.
-
Digital to Analogue - A digital-to-analogue chip processes digital sound - 1s , 0s that make signals and send it to the loudspeaker.
