List of TCP and UDP Port Numbers from Wikipedia, the Free Encyclopedia
List of TCP and UDP port numbers From Wikipedia, the free encyclopedia This is a list of Internet socket port numbers used by protocols of the Transport Layer of the Internet Protocol Suite for the establishment of host-to-host communications. Originally, these ports number were used by the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), but are also used for the Stream Control Transmission Protocol (SCTP), and the Datagram Congestion Control Protocol (DCCP). SCTP and DCCP services usually use a port number that matches the service of the corresponding TCP or UDP implementation if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.[1] However, many unofficial uses of both well-known and registered port numbers occur in practice.

List of TCP and UDP Port Numbers from Wikipedia, the Free Encyclopedia
List of TCP and UDP port numbers From Wikipedia, the free encyclopedia This is a list of Internet socket port numbers used by protocols of the transport layer of the Internet Protocol Suite for the establishment of host-to-host connectivity. Originally, port numbers were used by the Network Control Program (NCP) in the ARPANET for which two ports were required for half- duplex transmission. Later, the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full- duplex, bidirectional traffic. The even-numbered ports were not used, and this resulted in some even numbers in the well-known port number /etc/services, a service name range being unassigned. The Stream Control Transmission Protocol database file on Unix-like operating (SCTP) and the Datagram Congestion Control Protocol (DCCP) also systems.[1][2][3][4] use port numbers. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.[5] However, many unofficial uses of both well-known and registered port numbers occur in practice.

The Architecture and Evolution of Computer Game Engines
The architecture and evolution of computer game engines University of Oulu Department of Information Processing Sciences B.Sc thesis Rainer Koirikivi 12.3.2015 2 Abstract In this study, the architecture and evolution of computer game engines are analyzed by means of a literature review on the academic research body on the subject. The history of computer games, from early 1960s to modern day is presented, with a focus on the architectures behind the games. In the process, this study will answer a selection of research questions. The topics of the questions include identifying the common parts of a game engine, identifying the architectural trends in the evolution from early to present-day games and engines, identifying ways the process of evolution has affected the present state of the engines, and presenting some possible future trends for the evolution. As findings of the study, common parts of a game engine were identified as the parts that are specific to every game, with the suggestion that more detailed analyses could be made by concentrating on different genres. Increase in the size, modularity and portability of game engines, and improved tooling associated with them were identified as general trends in the evolution from first games to today. Various successful design decisions behind certain influential games were identified, and the way they affect the present state of the engines were discussed. Finally, increased utilization of parallelism, and the move of game engines from genre-specific towards genre-neutral were identified as possible future trends in the evolution. Keywords computer game, video game, game engine, game, software architecture, architecture, evolution 3 Foreword I'd like to thank my thesis supervisor Jouni Lappalainen for his continued support on what turned to be an epic journey into the fields of game engines and academic writing. -
List of TCP and UDP Port Numbers
List of TCP and UDP port numbers From Wikipedia, the free encyclopedia Jump to: navigation, search In computer networking, the protocols of the Transport Layer of the Internet Protocol Suite, most notably the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), but also other protocols, use a numerical identifier for the data structures of the endpoints for host-to- host communications.

The book you are about to read is not only the definitive technical resource for information on Windows 2000 software deployment, but represents an entirely new modality of book publishing. The founding concept behind Realtimepublishers.com is the idea of providing readers with high-quality books on today’s most critical IT topics—at no cost to the reader. Although this may sound like a somewhat impossible feat, it is made possible through the vision and generosity of corporate sponsors such as New Boundary Technologies (formerly Lanovation), who agree to foot the production expenses for the book and host it on their website for the benefit of their website visitors. It should be pointed out that the free nature of these books does not in any way diminish their quality. Without reservation, I can tell you that this book is the equivalent of any similar printed book you might find at your local bookstore (with the notable exception that it won’t cost you $30 to $80). In addition to the free nature of the books, this publishing model provides other significant benefits. For example, the electronic nature of this eBook makes events such as chapter updates and additions, or the release of a new edition of the book possible to achieve in a far shorter timeframe than is possible with printed books. Because we publish our titles in “real- time”—that is, as chapters are written or revised by the author—you benefit from receiving the information immediately rather than having to wait months or years to receive a complete product. -

Gay Engines: Imagining a Queer Development Platform for Video
Gay Engines: Imagining a Queer Development Platform for Video Games Cass Zegura MCM 1990: Honors Thesis/Project in Modern Culture and Media April 5, 2020 1 Preface The story of this project begins in the fall of 2017, at a crowded tapas bar in downtown Providence. My aunt and uncle, who live in Boston, had come down to visit and take me out to dinner. It was a perfectly ordinary night except in one regard: when I told my aunt and uncle about the classes I was taking that semester, a strange look crossed their faces. I thought the source of their confusion might be the computer science course I had mentioned, an upper-level design class called Independent Study in 2D Game Engines. I assumed that they, like I, had never heard of the term “game engine” before and thus did not know what it was. And as I launched into my explanation (which I won’t repeat here—I’ve already written an entire chapter dedicated to this question), the confusion diminished, but only somewhat, and we soon changed subjects. On a phone call with my mom a few days later, I learned the true source of my aunt and uncle’s befuddlement. In that noisy restaurant, the word “game” had transformed into the word “gay.” They thought that I was taking a class on 2D gay engines. No wonder they were confused! I would’ve been too. What the heck is a gay engine anyway? Of course, I didn’t know then that I was going to spend my senior year trying to answer that question. -

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Objective: Virtual Reality is the high-tech advanced technology developed in recent years, calcu- lated using high-speed computer to simulate a virtual three-dimension space. It allows users to have sensory simulation with vision, hearing, touch and so on. Users feel that they are in the area, and can observe all the thing in the three-dimensional space in real time and without limitation. The three-dimensional graphics rendering technology is not only the basis of software technique in virtual reality, but also the core of the three-dimensional graphics engine. In order to make more researchers have a more comprehensive understanding in 3D graphics engine theory, structure and principle, a detailed introduction was reviewed. Method: A large number of 3D en- gine theory were summarized, classified and compared. This paper introduces the definition of the virtual reality briefly, as well as mainly introducing the research status, basic structure and draw principle of the three-dimensional graphics engine.
