Client-side Prediction
Client-side prediction is a network programming technique used in video games intended to conceal negative effects of high latency connections. The technique attempts to make the player's input feel more instantaneous while governing the player's actions on a remote server. The process of client-side prediction refers to having the client locally react to user input before the server has acknowledged the input and updated the game state. So, instead of the client only sending control input to the server and waiting for an updated game state in return, the client also, in parallel with this, predicts the game state locally, and gives the user feedback without awaiting an updated game state from the server. Client-side prediction reduces latency problems, since there no longer will be a delay between input and client-side visual feedback due to network ping times. However, it also introduces a desynchronization of the client and server game states, which needs to be handled to keep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Network Programming
Computer network programming involves writing computer programs that enable processes to communicate with each other across a computer network. Connection-oriented and connectionless communications Very generally, most of communications can be divided into connection-oriented, and connectionless. Whether a communication is connection-oriented or connectionless, is defined by the communication protocol, and not by . Examples of the connection-oriented protocols include and , and examples of connectionless protocols include , "raw IP", and . Clients and servers For connection-oriented communications, communication parties usually have different roles. One party is usually waiting for incoming connections; this party is usually referred to as "server". Another party is the one which initiates connection; this party is usually referred to as "client". For connectionless communications, one party ("server") is usually waiting for an incoming packet, and another party ("cli ...

Video Game
Video games, also known as computer games, are electronic games that involves interaction with a user interface or input device such as a joystick, controller, keyboard, or motion sensing device to generate visual feedback. This feedback mostly commonly is shown on a video display device, such as a TV set, monitor, touchscreen, or virtual reality headset. Some computer games do not always depend on a graphics display, for example text adventure games and computer chess can be played through teletype printers. Video games are often augmented with audio feedback delivered through speakers or headphones, and sometimes with other types of feedback, including haptic technology. Video games are defined based on their platform, which include arcade video games, console games, and personal computer (PC) games. More recently, the industry has expanded onto mobile gaming through smartphones and tablet computers, virtual and augmented reality systems, and remote c ...

Latency (engineering)
Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag, as it is known in gaming circles, refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games. Latency is physically a consequence of the limited velocity at which any physical interaction can propagate. The magnitude of this velocity is always less than or equal to the speed of light. Therefore, every physical system with any physical separation (distance) between cause and effect will experience some sort of latency, regardless of the nature of the stimulation at which it has been exposed to. The precise definition of latency depends on the system being observed or the nature of the simulation. In communications, the lower limit of latency is determined by the medium being used to transfer information. In reliable two-way communication syst ...

Server (computing)
In computing, a server is a piece of computer hardware or software (computer program) that provides functionality for other programs or devices, called " clients". This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Client–server systems are usually most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledg ...

Client (computing)
In computing, a client is a piece of computer hardware or software that accesses a service made available by a server as part of the client–server model of computer networks. The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network. A client is a computer or a program that, as part of its operation, relies on sending a request to another program or a computer hardware or software that accesses a service made available by a server (which may or may not be located on another computer). For example, web browsers are clients that connect to web servers and retrieve web pages for display. Email clients retrieve email from mail servers. Online chat uses a variety of clients, which vary on the chat protocol being used. Multiplayer video games or online video games may run as a client on each computer. The term "client" may also be applied to computers or devices that run the client software or users that use th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duke Nukem 3D
''Duke Nukem 3D'' is a first-person shooter video game developed by 3D Realms. It is a sequel to the platform games ''Duke Nukem'' and ''Duke Nukem II'', published by 3D Realms. ''Duke Nukem 3D'' features the adventures of the titular Duke Nukem, voiced by Jon St. John, who fights against an alien invasion on Earth. Along with ''Wolfenstein 3D'' and ''Doom'', ''Duke Nukem 3D'' is considered to be one of many titles responsible for popularizing first-person shooters, and was released to major acclaim. Reviewers praised the interactivity of the environments, gameplay, level design, and unique risqué humor, a mix of pop-culture satire and lampooning of over-the-top Hollywood action heroes. However, it also incited controversy due to its violence, erotic elements, and portrayal of women. The shareware version of the game was originally released on January 29, 1996 as version 1.0 (later, the shareware version got re-released as version 1.1 on February 20, 1996 and re-released once ...

Retro Gamer
''Retro Gamer'' is a British magazine, published worldwide, covering retro video games. It was the first commercial magazine to be devoted entirely to the subject. Launched in January 2004 as a quarterly publication, ''Retro Gamer'' soon became a monthly. In 2005, a general decline in gaming and computer magazine readership led to the closure of its publishers, Live Publishing, and the rights to the magazine were later purchased by Imagine Publishing. It was taken over by Future plc on 21 October 2016, following Future's acquisition of Imagine Publishing. History The first 18 issues of the magazine came with a coverdisk. It usually contained freeware remakes of retro video games and emulators, but also videos and free commercial PC software such as ''The Games Factory'' and '' The Elder Scrolls: Arena''. Some issues had themed CDs containing the entire back catalogue of a publisher such as Durell, Llamasoft and Gremlin Graphics. On 27 September 2005, the magazine's original p ...

Dial-up
Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network (PSTN) to establish a connection to an Internet service provider (ISP) by dialing a telephone number on a conventional telephone line. Dial-up connections use modems to decode audio signals into data to send to a router or computer, and to encode signals from the latter two devices to send to another modem. History In 1979, Tom Truscott and Jim Ellis, graduates of Duke University, created an early predecessor to dial-up Internet access called the USENET. The USENET was a UNIX based system that used a dial-up connection to transfer data through telephone modems. Dial-up Internet has been around since the 1980s via public providers such as NSFNET-linked universities. The BBC established Internet access via Brunel University in the United Kingdom in 1989. Dial-up was first offered commercially in 1992 by Pipex in the United Kingdom and Sprint in the United Stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
