Input devices are hardware components used to provide data and control signals to a computer system. They allow users to interact with and input information into computers. Common examples include keyboards, mice, scanners, cameras, joysticks, and microphones. These devices can capture text, images, audio, and other forms of data for processing by the computer.

(1aii)
Storage devices are hardware used to store digital data, enabling the saving, retrieval, and transfer of information as needed. They are essential for retaining files, programs, and the operating system. Storage devices are categorized as primary (e.g., RAM, cache memory) for temporary data storage, and secondary (e.g., hard disk drives, solid-state drives, USB flash drives, cloud storage) for long-term or permanent data retention.

(1aiii)
Software refers to the set of programs, instructions, and rules that enable a computer to perform specific tasks. It is intangible and includes all computer applications, such as operating systems, word processors, and web browsers. Software is developed using programming languages and is classified into system software (like operating systems) and application software (like word processors and browsers).

(i) URL (Uniform Resource Locator): A URL is the address used to access resources on the internet.
