Road to Senior #2: How Computers Think in Numbers
The article explores the fundamental concepts of how computers process and represent data using numbers. It explains the significance of bits and bytes, hexadecimal notation, and how these elements contribute to computer architecture and programming. The author reflects on their own learning journey and the importance of understanding these foundational concepts in computer science.
- ▪The smallest unit of information in a computer is a bit, which can either be on (1) or off (0).
- ▪Eight bits make up one byte, allowing for 256 different combinations of values from 0 to 255.
- ▪Hexadecimal notation is used to simplify binary representation, where one hex digit corresponds to four bits.
