Two's Complement Arithmetic Concepts

The video tutorial explains the concept of overflow in computing, focusing on how it occurs when the result of an operation exceeds the storage capacity of a predefined space. It covers overflow in both two's complement and unsigned numbers, illustrating how overflow is detected in these systems. The tutorial provides scenarios to demonstrate overflow, emphasizing the importance of understanding this concept in binary arithmetic. The session concludes with a brief introduction to the next topic, binary codes.
