1. The concept of Artificial Neural Networks (ANNs) has its roots in the mid-20th century when Warren McCulloch and Walter Pitts introduced a mathematical model of a neural network. However, it wasn't until the 1980s and 1990s, with the introduction of the backpropagation algorithm and increased computing power, that ANNs became a major field of research.

2. An Artificial Neural Network (ANN) is a computational model based on the structure and functions of biological neural networks. It is designed to simulate the behavior of biological systems composed of "neurons". ANNs are capable of machine learning and pattern recognition.

3. The main differences between computers and neural networks are in the way they process information. Computers use explicit programming to process information, while neural networks use a set of learning rules to understand and solve complex patterns. Also, computers are more efficient at tasks that involve precise calculations, while neural networks excel in recognizing patterns and making predictions.

4. The basic reasons for building ANNs include their ability to learn and adapt to new inputs; their ability to handle noisy or incomplete data; their parallel processing capability; and their ability to generalize from the input data.

5. ANNs work by simulating a large number of interconnected processing nodes, called artificial neurons or perceptrons. Each perceptron receives inputs, multiplies them by some weight, and passes them through a nonlinear function to produce an output. The network learns by adjusting the weights based on the error of the output.

6. Some of the design issues in ANNs include determining the optimal number of layers and neurons, selecting the appropriate learning rule, and avoiding overfitting.

7. Supervised learning is a type of machine learning where the model is trained on a labeled dataset, i.e., a dataset where the correct output is known. The model makes predictions based on this training and is corrected by the supervisor if the predictions are wrong.

8. Unsupervised learning, on the other hand, is a type of machine learning where the model is trained on an unlabeled dataset. The model learns to recognize patterns and structures in the data without any external guidance.

9. ANNs have a wide range of applications, including image and speech recognition, natural language processing, financial forecasting, medical diagnosis, and even in self-driving cars.

10. Advantages of ANNs include their ability to learn and generalize from the input data, their tolerance to noisy data, and their ability to process information in parallel. Disadvantages include their black-box nature, which makes it difficult to interpret their internal workings, their tendency to overfit if not properly designed and trained, and the large amount of computational resources they require.
