Ethical Considerations in Technology Development and Use
- Algorithmic bias and fairness
- Transparency and accountability
- Human-centered design
Education's Role in Addressing Ethical Concerns
- Fostering critical thinking and digital literacy skills
- Promoting ethical awareness and responsible technology use
- Encouraging interdisciplinary collaboration to address societal changes.
What is Computing?
- A goal-oriented activity involving the creation and use of computers.
- It encompasses various aspects, including:
- Designing and constructing hardware and software systems.
- Processing, structuring, and managing information.
- Problem-solving.
- Making computer systems behave intelligently.
- Creating and using communication and entertainment media.
- Finding and gathering information.
History and Evolution of Computing
- Ancient Times: Abacus (circa 3000 BCE).
- 17th – 19th Century: Mechanical Calculators.
- 1837: Babbage's Analytical Engine, a foundational concept for modern computers.
- Late 19th Century: Hollerith's Tabulating Machine, which used punch cards to process data.
What is a Computer?
- A computer is a device that processes data.
- It performs four major functions: input, process, output, and storage.
- Data is a representation of a fact, figure, or idea.
- Information is organized and presented data that is meaningful to humans.
###Â Data Representation
- Computers represent data electrically.
- All data is translated into binary, a series of 0s and 1s.
- Each 0 or 1 is a bit.
- Four bits combine to form a nibble.
- Eight bits combine to form a byte.
Binary
- Kilobyte = 1024 bytes
- Megabyte = 1,048,576 bytes
- Gigabyte = 1,073,741,824 bytes
- Terabyte = 1,099,511,627,776 bytes
Computer Components
- A computer system uses hardware and software.
- Hardware is the physical parts of a computer.
- Software are sets of procedures that enable the hardware to perform tasks.
Computer Hardware
- A computer's hardware consists of a processor, storage, input/output devices.
- The processor, or CPU, manipulates and transforms data.
- Storage holds data and programs.
- Primary storage holds data and programs needed immediately and is temporary.
- Secondary storage holds data and programs for long-term use and is permanent.
- Input/Output devices or peripherals enable communication with humans and other computers.
- Input devices accept input from humans and convert it into a form the computer can understand.
- Output devices convert signals from the computer into a form humans can understand.
Computer Software
- Software translates human languages into binary computer languages.
- Application software performs specific tasks for the user.
