Summary

This CS50 lecture, delivered in Spanish by David J. Malan, introduces fundamental concepts of computer memory. It begins with a visual demonstration of how images are represented as pixels and bits, leading to an explanation of hexadecimal notation and its use in representing colors and memory addresses. The lecture then introduces pointers, explaining how to obtain and store memory addresses using the & and * operators in C. Through live coding examples, Malan illustrates how to print addresses with %p and discusses the size of pointers. The session covers the basics of memory allocation, including the stack and heap, and touches on common pitfalls like segmentation faults. The lecture is part of the CS50x course, designed for beginners but providing a solid foundation for understanding memory management in programming.
