Have you ever thought about how computers can be both powerful and creative? One of the coolest things about computers is that they use circuits, which can be seen as a form of art. If you have a creative idea, you can bring it to life using technology and circuits.
Every time you use a computer, it processes information using electrical signals. These signals can be either on or off, which we represent as ones and zeros. To make sense of these signals and produce an output, computers use millions of tiny electronic parts that work together to form circuits.
Let’s dive into how circuits handle information in binary form. Imagine a simple circuit that flips an electrical signal. If the input is a 1, the output becomes a 0, and if the input is a 0, the output becomes a 1. This type of circuit is called a NOT gate.
There are also more complex circuits. For example, an AND gate takes two signals and only outputs a 1 if both inputs are 1. If either input is 0, the output will be 0. These small circuits perform basic logical operations, and by connecting them, we can create more complex circuits for intricate calculations.
One example of a complex circuit is an adder, which can add two bits together. Each bit is either a 1 or a 0, and the adder calculates their sum. The possible results are: 0 plus 0 equals 0, 0 plus 1 equals 1, and 1 plus 1 equals 2. Sometimes, the output needs two wires to show the sum in binary form.
Once you have a single adder, you can connect several adders to add larger numbers. For instance, an 8-bit adder can add numbers like 25 and 50. Each number is represented with 8 bits, so 16 signals enter the circuit. The 8-bit adder uses many smaller adders to find the total sum.
Different circuits can also handle other basic math operations, like subtraction or multiplication. In fact, everything a computer does involves many simple operations done in order. Each operation is simple enough for a person to do, but computers do them much faster.
In the past, circuits were huge and slow. An 8-bit adder could be as big as a fridge and take minutes to do a simple calculation. Today, circuits are tiny and incredibly fast. Smaller circuits are quicker because the electrical signals travel shorter distances. Electricity moves almost at the speed of light, allowing modern circuits to perform billions of calculations every second.
Whether you’re playing a game, recording a video, or exploring space, all these activities need fast processing of lots of information. Behind the scenes, countless tiny circuits turn binary signals into websites, videos, music, and games. These circuits can even help decode DNA for diagnosing and treating diseases.

One of the fascinating aspects of circuitry is that it can serve as an art form. If you have a creative idea, you can express that idea through circuits. Technology allows you to bring your concepts to life.
Every input or output of a computer represents a type of information, which can be depicted as on or off electrical signals, or as ones and zeros. To process the incoming information and generate the output, a computer modifies and combines these input signals. This is accomplished using millions of tiny electronic components that work together to form circuits.
Let’s examine how circuits can modify and process information represented in binary form. Consider a simple circuit that takes an electrical signal and inverts it. If the input signal is a 1, the output will be a 0, and vice versa. The input signal differs from the output signal, which is why we refer to this circuit as a NOT gate.
More complex circuits can take multiple signals, combine them, and produce different results. For instance, a circuit that takes two electrical signals will output a 0 if either of the input signals is a 0. This circuit will only output a 1 if both input signals are 1s, and we refer to this circuit as an AND gate.
There are many small circuits like these that perform simple logical operations. By connecting these circuits, we can create more complex circuits that handle more intricate calculations. For example, an adder circuit can add two bits together. This circuit takes two individual bits, each being a 1 or a 0, and calculates their sum. The possible outcomes are: 0 plus 0 equals 0, 0 plus 1 equals 1, or 1 plus 1 equals 2. The output may require two wires, as it can take up to two binary digits to represent the sum.
Once you have a single adder for adding two bits, you can connect multiple adder circuits side by side to add larger numbers. For example, an 8-bit adder can add the numbers 25 and 50. Each number is represented using 8 bits, resulting in 16 electrical signals entering the circuit. The 8-bit adder contains numerous smaller adders that collectively calculate the sum.
Different electrical circuits can perform other basic calculations, such as subtraction or multiplication. In fact, all the information processing performed by a computer consists of numerous simple operations executed in sequence. Each operation is straightforward enough to be performed by a human, but the circuits within computers operate at a significantly faster pace.
Historically, these circuits were large and cumbersome; an 8-bit adder could be as large as a refrigerator and take minutes to perform a simple calculation. Today, computer circuits are microscopic and operate at much higher speeds. The reason smaller circuits are faster is that the electrical signals have a shorter distance to travel. Electricity moves at nearly the speed of light, enabling modern circuits to perform billions of calculations per second.
Whether you are playing a game, recording a video, or exploring the cosmos, all technological activities require rapid processing of vast amounts of information. Beneath this complexity lies a multitude of tiny circuits that convert binary signals into websites, videos, music, and games. These circuits can even assist in decoding DNA for diagnosing and treating diseases.
