Why computer use binary logic (0,1) instead of use a ternary or something else?

In the early computing systems it was easier to use two hard states 0 and 1 rather than three or more discrete levels as it means that you can hard switch your devices. Once your programming schemes are based around binary and working well, why change to another system.
What would be the advantage of using a tri-state logic in the majority of applications? This needs to be considered both from speed of processing and ease of implimentation.

it is not just easier to use, it is simplest possible logic (you can't really make a logic out of one value), but it is quite enough for everything, at the same time. suppose you have some 4-valued predicate F(x) that can be all the values v1, v2, v3 or v4. In terms of 2-valued predicates, that translates into two predicates P(x) and Q(x), that are defined like this:
• P(x) = v1 iff F(x) = v1, or v2;
• Q(x) = v1 iff F(x) = v1, or v3

## 1. Why do computers use binary logic (0,1)?

Computers use binary logic because it is a simple and efficient way to represent and process information. Binary logic is based on just two symbols, 0 and 1, which can be easily represented by electrical signals in computer hardware.

## 2. How does binary logic work in computers?

In binary logic, 0 represents a low voltage signal and 1 represents a high voltage signal. These signals are used to represent the two states of a switch, which is the basic building block of all digital computers. By combining multiple switches, complex logical operations can be performed.

## 3. What are the advantages of using binary logic in computers?

Binary logic allows for easier and more accurate data processing, as the two states of 0 and 1 can clearly represent on and off, true and false, or any other binary decision. It also allows for easier storage and transmission of data, as it can be represented by a series of 0s and 1s.

## 4. Are there any alternatives to binary logic in computers?

While binary logic is the most commonly used form of logic in computers, there are other alternatives such as ternary logic (using three symbols) and quantum logic (based on the principles of quantum mechanics). However, these are not as widely adopted due to the complexity and limitations in current technology.

## 5. How does binary logic contribute to the speed and efficiency of computers?

Binary logic allows for faster and more efficient processing of data as it can be easily translated into electrical signals and manipulated by computer hardware. This allows for quicker decision making and data storage, making computers more efficient in performing tasks.
