Because it's much, much easier to design electronic two-way switches that electronic ten-way switches. A two-way switch leads to binary.
Electronic fund transfers are very important in the banking sector. They are convenient, faster, and easier. They also eliminate the need for paper checks.
Most sensors have an electrical output because electrical signals are easy to transmit, process, and analyze in electronic systems. Converting physical measurements into electrical signals allows for easier integration with other electronic devices and systems for data processing and feedback control. Additionally, electrical signals are less prone to interference and noise compared to other types of signals.
Binary system is used in microprocessors because it simplifies electronic circuitry by representing data using two voltage levels (0 and 1), which can be easily implemented using electronic switches like transistors. This simplicity allows for faster processing speeds, easier storage and manipulation of data, and efficient communication between different components in a computer system.
Electric is easier and faster then mechanical processing, Your question does not give much information but look into Binary, Dont look into computers, Binary is a counting system like our counting system decimal (0,1,2..,9,10,11,12...,19,20,21 ect). We use binary as it is base 2, And electric can have two states, on or off (1 or 0). To use decimal we would need to be able have 10 different values.
Binary coded decimal (BCD) is easier to convert between displayed or printed form than is pure binary.
binary
Little bit easier.
It is used because it is easier to convert to and from binary to hexadecimal than decimal, and it uses less characters than binary. For instance: decimal: 65535 hex: FFFF binary: 1111111111111111
It is the easiest way to do it reliably: on/off signals are easier to distinguish than more levels. Note: there were a few computers built in the USSR that used ternary numbers instead of binary (e.g. + voltage, 0 voltage, - voltage). They worked but the circuits to identify the 3 levels were much more complex than for 2 levels.
If you are referring to EBT, it means electronic benefit transfer. It is the new name for food stamps, in the electronics form of benefit. It comes in a credit card format and is easier and faster to use and receive benefits.
Binary is easier for the computer to understand. It is also easier to handle and is not costly.
