Mobile Code
In distributed computing, code mobility is the ability for running Computer program, programs, code or objects to be data migration, migrated (or moved) from one machine or application to another. This is the process of moving mobile code across the nodes of a Computer network, network as opposed to distributed computation where the ''data'' is moved. It is common practice in distributed systems to require the movement of code or processes between parts of the system, instead of data. Examples of code mobility include scripts downloaded over a network (for example JavaScript, VBScript), Java applets, ActiveX controls, Flash animations, Shockwave movies (and Xtras), and Macro (computer science), macros embedded within Microsoft Office documents. Overview The purpose of code mobility is to support sophisticated operations. For example, an application can send an object to another machine, and the object can resume executing inside the application on the remote machine with the same ...

Distributed Computing
Distributed computing is a field of computer science that studies distributed systems, defined as computer systems whose inter-communicating components are located on different networked computers. The components of a distributed system communicate and coordinate their actions by passing messages to one another in order to achieve a common goal. Three significant challenges of distributed systems are: maintaining concurrency of components, overcoming the lack of a global clock, and managing the independent failure of components. When a component of one system fails, the entire system does not fail. Examples of distributed systems vary from SOA-based systems to microservices to massively multiplayer online games to peer-to-peer applications. Distributed systems cost significantly more than monolithic architectures, primarily due to increased needs for additional hardware, servers, gateways, firewalls, new subnets, proxies, and so on. Also, distributed systems are prone to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Office
Microsoft Office, MS Office, or simply Office, is an office suite and family of client software, server software, and services developed by Microsoft. The first version of the Office suite, announced by Bill Gates on August 1, 1988, at COMDEX, contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint — all three of which remain core products in Office — and over time Office applications have grown substantially closer with shared features such as a common spell checker, Object Linking and Embedding data integration and Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand. The suite currently includes a word processor (Word), a spreadsheet program ( Excel), a presentation program ( PowerPoint), a notetaking program ( OneNote), an email client ( Outlook) and a file-hosting service client (OneDrive). The Windows version includes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
