Here’s a brief overview of the evolution of hard disk drives. ### 1950s: The Beginning - **1956**: IBM introduced the first hard disk drive, the IBM 305 RAMAC (Random Access Method of Accounting and Control). It used 50, 24-inch platters and could store about 5 MB of data.
Magnetic-core memory is a type of non-volatile computer memory that was widely used from the 1950s to the 1980s before being largely replaced by semiconductor memory technologies. It utilizes tiny magnetic ferrite rings, known as cores, to store bits of information. Each core represents one bit of data, with the core being magnetized in one direction to represent a "0" and the opposite direction for a "1". **Key Features of Magnetic-Core Memory:** 1.
The Swedish Board for Computing Machinery, known as "Svenska datorkommittén" in Swedish, is an organization that focuses on advancing the field of computing in Sweden. It is often associated with promoting research, education, and best practices in computer science and technology. The board typically engages with academic institutions, industry stakeholders, and government bodies to enhance collaboration and innovation within the computing sector.
Internet culture refers to the various social behaviors, norms, values, and practices that have emerged and evolved within online communities and platforms. This culture encompasses a wide range of phenomena, including memes, viral trends, subcultures, and the ways in which people interact, communicate, and express themselves online.
Demon Internet was one of the first Internet Service Providers (ISPs) in the United Kingdom, founded in 1992. Initially, it gained attention for offering dial-up internet services, which allowed users to connect to the Internet via telephone lines. Demon's service was notable during the early years of the Internet in the UK, as it provided both personal and business internet access.
The Federal Internet Exchange (FIX) is a U.S. government initiative designed to enhance the efficiency, security, and resilience of internet traffic routing for federal agencies. It aims to facilitate direct interconnection among federal agencies, promote cross-agency collaboration, reduce reliance on commercial internet service providers, and improve overall network performance. Key features of FIX include: 1. **Direct Connectivity**: FIX allows federal agencies to connect directly to one another, bypassing the need to route traffic through commercial networks.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
