ICT Essentials - Role and Impact

Study Notes

ICT plays a crucial role in transforming various sectors, including business, education, and healthcare by enhancing communication and data management.
The ethical practice of ICT focuses on improving performance and facilitating learning through effective use and management of technology.

Early mechanical systems evolved into modern digital technology via significant technological advancements over time, shaping computing devices and their functionalities.

CPU: The central processing unit acts as the brain, executing instructions and managing data flow.
Memory: Responsible for temporarily storing data and programs that the CPU is actively using.
Storage: Devices such as hard drives and SSDs keep data and software when not in use.
Peripherals: External devices connected to a computer, enabling input (like keyboards) and output (like monitors) functions.

ICT encompasses a diverse range of technological tools and resources used for transmitting, storing, creating, sharing, or exchanging information.
Vital for effective communication, knowledge transfer, and data management in both personal and professional environments.

Digital: Operates using discrete binary values, enhancing processing and storage efficiency compared to analog systems.
Interconnected: Allows seamless communication and data exchange across various devices and networks, exemplified by the internet.
Interoperable: Ensures compatibility between different devices, software, and networks for smooth operation.
Scalable: Designed to grow and accommodate increasing data needs without compromising performance.
Secure: Protects sensitive data from unauthorized access, ensuring confidentiality and integrity.
User-Friendly: Prioritizes ease of use through intuitive interfaces, making technology accessible to a broader audience.
Adaptable: Capable of evolving to meet changing technological advancements and user requirements.
Reliable: Built with mechanisms to ensure consistent operation and minimize failures or downtime.
Efficient: Designed to handle large data volumes rapidly while optimizing resource use to reduce costs.
