Study Notes

Medical and Health Information

Medical informatics, or health informatics, integrates health sciences, ICT, and data analytics.
Its aim is to enhance patient care, healthcare processes, and public health.

Computer Basic Concepts

Software: Programs that operate computer systems.
Hardware: Physical components of a computer, including keyboards and printers.
Data: Raw, unorganized facts needing processing.
Information: Organized, processed data that presents meaningful context.
Knowledge: Involves rules, relationships, ideas, and experiences for decision-making.

Data Processing Steps

Input: Gathering and capturing data (e.g., inputting student names).
Processing: Converting input into useful outputs (e.g., calculations).
Output: Producing useful information, typically in documents or reports.
Feedback: Information used to adjust input or processing, critical for decision-making.

Computer Architecture

John Von Neumann proposed a model in the 1940s outlining basic computer system architecture.
Computers consist of data processors handling input, processing, and output.

Components of Von Neumann Model

Input/Output Architecture:
- Input devices: Allow user interaction (e.g., keyboards, scanners).
- Output devices: Display processed information (e.g., monitors, printers).
Memory Types:
- Primary Memory: Temporary storage for data and programs (e.g., RAM).
- Secondary Memory: Permanent storage for large amounts of data (e.g., hard drives).
- ROM: Non-volatile memory for essential system information, cannot be modified.
Central Processing Unit (CPU):
- The brain of the computer, also known as the processor or microprocessor.
- Composed of the Arithmetic/Logic Unit (ALU) for operations and the Control Unit for instruction execution.
System Bus:
- Pathway of cables for data transfer between CPU and memory.
- Includes:
  - Data Bus: Carries the data.
  - Address Bus: Determines data destination.
  - Control Bus: Manages data processing states.
Motherboard:
- Main circuit board connecting all hardware components.
- Houses both attachable electronic components and integrated circuits.
