Time-sharing systems represent a significant evolution in computing, allowing multiple users to interact with a computer simultaneously. This concept emerged from the need for more efficient use of computing resources, which were, at the time, expensive and limited. ### Key Stages in the Evolution of Time-Sharing Systems: 1. **Early Computing (1950s)**: - Computers were large, expensive, and primarily used for batch processing.
In graph theory, the complement of a graph is a graph that contains the same set of vertices but has edges that are not present in the original graph.
A Type-in program refers to a type of computer program where the user is expected to manually enter (or "type in") the code into a computer or programming environment. This practice was particularly popular in the early days of personal computing, especially in the 1980s and 1990s, when magazines and books would publish source code listings for users to type into their own computers. Type-in programs often serve as a way to teach programming concepts, allowing users to learn by doing.
Chordal completion, also known as chordal graph completion, refers to the process of transforming a given graph into a chordal graph. A chordal graph (or "perfect graph") is defined as a graph in which every cycle of four or more vertices has a chord, which is an edge that is not part of the cycle but connects two vertices of the cycle. The process of chordal completion involves adding edges to the original graph in such a way that the resulting graph becomes chordal.
An edge cycle cover in graph theory is a collection of cycles that covers every edge of a graph exactly once. In other words, it is a set of cycles in which each edge of the graph is included in exactly one of the cycles. This concept is particularly relevant in the study of Eulerian paths and circuits.

Al Gore, the former Vice President of the United States, is known for his advocacy on environmental issues and climate change, but he also has a significant connection to information technology. In the 1990s, while serving under President Bill Clinton, Gore promoted the development of the Internet, referring to it as "The Information Superhighway." He championed initiatives that contributed to the expansion and accessibility of the Internet, including federal funding for research and development in information technology.
As of my last knowledge update in October 2021, Barry Appelman does not appear to be a widely recognized figure in literature, politics, entertainment, or other public domains. It's possible that he could be a private individual, a professional in a specific field, or someone who has gained recognition after my last update.
Digital Archaeology is an exhibition that showcases the intersection of archaeology and digital technology. It highlights how digital tools and methods are transforming the practice of archaeology, enabling researchers and the public to engage with archaeological data and heritage in new ways. The exhibition may include a range of digital installations, interactive displays, virtual reconstructions, and 3D models that present archaeological findings and allow visitors to explore ancient sites or artifacts in an immersive manner.
Erwise is recognized as one of the first graphical web browsers, developed in 1992 at the Helsinki University of Technology in Finland. It was created by a group of students including Timo Sirainen and was designed to display HTML documents with images, making it a pioneer in facilitating web navigation in a more user-friendly manner compared to text-based browsers like Lynx. Erwise was notable for its ability to display not only text but also images, which was a significant step forward at the time.
FrameNet is a lexical database of the English language that is based on the theory of Frame Semantics, developed by cognitive linguist Charles J. Fillmore. The primary goal of FrameNet is to provide a comprehensive resource for understanding how words in the English language relate to one another within specific conceptual frameworks, or "frames.
The history of Facebook is a fascinating journey that reflects the evolution of social media and digital communication.

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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
