WDR paper computer
The term "WDR paper computer" doesn’t refer to a widely recognized concept or technology in the field of computing or technology as of my last update in October 2023. It’s possible that it could refer to a specific project, product, or concept that was introduced after that date or is niche within a particular field. If "WDR" stands for something specific, such as a particular application or methodology in computing (for example, Wide Dynamic Range), more context would help clarify.
Word RAM
Word RAM (or Word Random Access Memory) is a type of computer memory that provides data storage where data is accessible in words, which are typically larger than a byte. In traditional computer architecture, memory is often organized in bytes (8 bits), but in Word RAM, the smallest addressable unit is typically a word, which can be 16 bits, 32 bits, or 64 bits, depending on the system's architecture.
X-machine
X-machine is a theoretical model used in the field of computer science, specifically in the study of formal languages and automata theory. It was introduced by computer scientist Egon Börger as a formalization intended to bridge the gap between high-level programming languages and low-level computational models like Turing machines. An X-machine is characterized by its ability to represent state transitions using a set of rules that define how it processes input and changes state based on that input.
Zeno machine
The Zeno machine is a hypothetical concept in the field of computer science and philosophy, often discussed in the context of computability and the limits of computation. It is named after Zeno's paradoxes, which are philosophical problems that explore the nature of motion and infinity. In the context of computation, the Zeno machine is usually characterized by its ability to perform an infinite number of operations in a finite amount of time.
