Where did Bytes Come From? - Computerphile

TL;DR

This content discusses the history and development of bits and bytes, including their invention and the adoption of the byte as a standard unit of storage.

Transcript

there's plenty of superb anecdotes about the history of the bite and and so on i suppose the earlier question uh which if we want to go right back to ground zero who invented the word bit a chap at guess where bell labs john chooky worked with shannon and others a bit i think it was here in a paper in 1947 actually uttered the word bit rather than ...

Questions & Answers

Q: Who invented the term "bit"?

The term "bit" was coined by a researcher at Bell Labs named John Chooky in 1947, who worked with Shannon and others.

Q: Why did early computers transition from word-based systems to bytes?

Early computer pioneers were interested in building computers for scientific applications that required decimal accuracy, which led to the development of the byte as a unit of storage for holding characters.

Q: What is the significance of the multiplying factor 3.322 in binary circuitry?

The multiplying factor of 3.322 indicates how much more binary circuitry is needed in the arithmetic unit of a computer compared to decimal arithmetic. It is necessary to maintain accuracy in calculations.

Q: Why did IBM propose the use of eight-bit bytes?

IBM recognized the limitations of early character handling in computers and suggested the use of eight-bit bytes to address the inefficiencies. This allowed for individual addressing and future expansion, benefiting both commercial and scientific computing.

Summary & Key Takeaways

• The term "bit" was first used in 1947 by a researcher at Bell Labs, and early computers were word-based before the concept of the byte emerged.

• Real programmers prioritize numbers and accuracy over text, leading to the development of binary arithmetic and decimal accuracy calculations.

• IBM played a crucial role in commercial computing and proposed the standardization of the byte as an eight-bit entity, allowing for efficient data storage and manipulation.
