Study Notes

The Mobile World and Information Technology

Information technology encompasses any technology that helps produce, manipulate, store, communicate, and disseminate information.
Smartphones and tablets significantly impact everyday activities and operations.

Storage Hardware and Capacity

Storage capacity is quantified in bytes, with various hierarchical measures:
- 1 byte = 1 character of data
- 1 kilobyte (KB) = 1,024 characters
- 1 megabyte (MB) = 1,048,576 characters
- 1 gigabyte (GB) = over 1 billion characters
- 1 terabyte (TB) = over 1 trillion characters
- 1 petabyte (PB) = about 1 quadrillion characters
- Further large units include exabyte (EB), zettabyte (ZB), and yottabyte (YB).

Operating Systems

The operating system (OS) is a critical component of computer hardware, managing software and hardware interactions.
Common operating systems include:
- Windows
- Unix
- Linux
- Mac OS

Application Software

Application software is designed for specific tasks such as:
- Problem-solving
- Completing work tasks
- Entertainment
Compatibility is crucial; specific applications may only function on particular operating systems (e.g., Linux apps vs. Windows apps).

Ethical Considerations in Information Technology

Ethics involves moral principles guiding individual or group behavior.
Key ethical challenges in IT development include:
- Speed and scale, which impact security and personal privacy.
- Unpredictability, making IT less reliable than other technologies.
- Complexity, leading to potentially unmanageable computer systems.
