Study Notes
ICT systems are designed to meet specific user needs by selecting appropriate hardware, software, and accessibility features. These systems must consider user requirements, task complexity, and compatibility.
- Specified Needs — particular requirements of a user or organization that ICT systems must fulfill. Example: A business may need systems for data processing and communication.
- Digital Devices — hardware selected based on user requirements like portability and processing power. Example: A desktop computer is suitable for graphic design due to its high processing power.
- Peripheral Devices — extend the functionality of digital systems, considering user abilities and task requirements. Example: Alternative keyboards assist users with visual impairments.
- System Software — manages hardware resources and provides a platform for applications. Example: Operating systems like Windows or macOS.
- Application Software — performs specific user tasks such as word processing or image editing. Example: Adobe Photoshop for editing promotional photographs.
- Accessibility — design of ICT systems for use by people with various abilities and disabilities. Example: Screen readers for visually impaired users.
