programmes

The word programme (British English) or program (American English) refers to a set of instructions that a computer executes to perform a task, or to content scheduled for broadcast on radio or television. The spelling difference reflects regional conventions.

In computing, programmes refer to software that runs on devices. They include application software (word processors, web browsers), system software (operating systems, device drivers), and utilities (maintenance tools). Programs are written in programming languages and translated into executable code by compilers or interpreted at run time. They interact with users through interfaces and with data through input/output operations. Programmes rely on operating systems, libraries, and APIs, and may be distributed as binaries, installers, or source code.

The development of programmes follows a lifecycle: requirements, design, coding, testing, deployment, and maintenance. Methodologies such as waterfall, agile, and DevOps influence workflow. Quality attributes include correctness, reliability, performance, and security. Platforms vary; some programmes are cross‑platform, others are native to Windows, macOS, Linux, or mobile environments. Licensing models range from proprietary to open source, freeware, and shareware.

In broadcasting, a programme is a scheduled item of content, such as a TV or radio show, often organized into seasons or episodes. The term denotes the planned sequence of programming presented to an audience. The content may be produced by networks, studios, or independent producers.
