Answer 1

Cell phone conversations and computer data are transmitted as binary data, using a sequence of ones and zeros. Electric circuits use analog and digital signals, with digital signals represented by transistors that act as on-off switches.

Step-by-step explanation:

Cell phone conversations, and television voice and video images are commonly transmitted as digital data, by converting the signal into a sequence of binary ones and zeros. This allows clearer data transmission when the signal is weak, and allows using computer algorithms to compress the digital data to transmit more data in each frequency range. Computer data as well is transmitted as a sequence of binary ones and zeros, each one or zero constituting one bit of data.

In modern electronic devices, digital signals are used with diodes and transistors to perform tasks such as data manipulation. Electric circuits carry two types of electrical signals: analog and digital. An analog signal varies continuously, whereas a digital signal switches between two fixed voltage values. Digital circuits like those found in computers use a transistor to represent binary code, where it behaves like an on-off switch. Integrated circuits contain vast collections of transistors on a single piece of silicon, designed to handle digital signals.
