Why IBM Chose Eight-Bit Bytes: The Birth of a Standard in Computing History

The history of computing is a story of innovation, trial and error, and the emergence of standards that have shaped the modern digital world. One such milestone is the decision by IBM to adopt the eight-bit byte for memory addressing. This seemingly simple choice has had far-reaching effects, establishing the eight-bit byte as the de facto standard in modern computing. Understanding why IBM made this decision, and how it influenced the entire industry, sheds light on both the technical and practical considerations of early computer architecture.

In this article, we will dive into the reasoning behind IBM’s adoption of the eight-bit byte, exploring historical, technical, and industry-related factors. We will look at the evolution of byte sizes, how IBM’s decisions shaped computing systems, and why the eight-bit byte became so widely adopted. This deep dive will offer a comprehensive understanding of why the eight-bit byte is now the standard in nearly all modern computers, and why IBM’s influence continues to be felt today.
