Desktop publishing software (abbreviated DTP) is the creation of printed materials using page layout on a personal computer. When used skilfully, desktop publishing software can produce printed literature with attractive layouts and typographic quality comparable to traditional typography and printing. This technology allows individuals, businesses, and other organizations to self-publish a wide range of printed matter—from menus and local newsletters to books, magazines, and newspapers—without the sometimes-prohibitive expense of commercial printing.
Desktop publishing methods provides more control over design, layout, and typography than word processing does. However, word processing software has evolved to include some, though by no means all, capabilities previously available only with professional printing or desktop publishing.
Computer programming (often shortened to programming or coding) is the process of designing, writing, testing, debugging, and maintaining the source code of computer programs. This source code is written in one or more programming languages. The purpose of programming is to create a set of instructions that computers use to perform specific operations or to exhibit desired behaviors. The process of writing source code often requires expertise in many different subjects, including knowledge of the application domain, specialized algorithms and formal logic.
Web design is a broad term covering many different skills and disciplines that are used in the production and maintenance of websites.[1] The different areas of web design include; web graphic design, interface design, authoring; including standardised code and proprietary software, user experience design and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all.[2] The term web design is normally used to describe the design process relating to the front-end (client side) design of a website including writing mark up, but this is a grey area as this is also covered by web development. Web designers are expected to have an awareness of usability and if their role involves creating mark up then they are also expected to be up to date with web accessibility guidelines.
A computer network, or simply a network, is a collection of computers and other hardware components interconnected by communication channels that allow sharing of resources and information.[1] Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network. Simply, more than one computer interconnected through a communication medium for information interchange is called a computer network.
Networks may be classified according to a wide variety of characteristics, such as the medium used to transport the data, communications protocol used, scale, topology, and organizational scope.
Communications protocols define the rules and data formats for exchanging information in a computer network, and provide the basis for network programming. Well-known communications protocols include Ethernet, a hardware and link layer standard that is ubiquitous in local area networks, and the Internet protocol suite, which defines a set of protocols for internetworking, i.e. for data communication between multiple networks, as well as host-to-host data transfer, and application-specific data transmission formats.
