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.
