The second part of the lesson about numbers and how they are stored in computers. Data structures are discussed at the end of the lesson.
In this video you will learn about:
The precision in floating-point numbers, covering topics like mantissa digits, exponent signs, and negative/positive representation. The video introduces binary arithmetic, emphasizing the quick overflow of binary additions. The significance of word size in processors, varying from 8 to 64 bits, is highlighted. It touches on integer limits, discussing MININT and MAXINT, and mentions hexadecimal numbers and character encoding. The transition to data structures is introduced, such as strings, records, arrays, and lists. The importance of selecting the right data structure for efficient searches and changes is emphasized, considering trade-offs between speed and memory usage.
