Study Notes

Medical and Health Information

Medical informatics combines health sciences, information and communication technologies (ICT), and data analytics to enhance patient care and public health outcomes.

Computer Basic Concepts

Software refers to programs that operate a computer system.
Hardware encompasses physical components, such as keyboards, speakers, and printers.
Data consists of raw, unorganized facts requiring processing for meaningful use.
Information is processed data that is structured and presented in a meaningful context.
Knowledge includes rules, relationships, ideas, and experiences useful for decision-making.

Data Processing Activities

Input is about gathering and capturing raw data (e.g., entering student names).
Processing transforms input into useful outputs, including calculations and data sorting.
Output produces useful information, typically in documents or reports (e.g., data reports for managers).
Feedback is vital for adjustments in input or processing, enabling corrective actions based on identified errors or issues.

Computer Architecture

John Von Neumann's model describes computer systems, emphasizing data processing flow: input data, processing, and output delivery.

Components of Von Neumann Model

Input/Output Architecture:
- Input devices allow interaction with computers (e.g., keyboards, mice, scanners).
- Output devices display results (e.g., monitors, printers).
Memory:
- Stores both data and programs for processing.
- Primary Memory: Temporary storage (e.g., RAM).
- Secondary Memory: Long-term data storage (e.g., hard disks, flash drives, CDs).
- ROM: Non-volatile memory fixed by the manufacturer, essential for booting the computer.
Central Processing Unit (CPU):
- The CPU acts as the brain of the computer, responsible for instruction execution.
- Composed of:
  - Arithmetic/Logic Unit (ALU): Performs mathematical and logic operations.
  - Control Unit: Interprets user data and sends signals to the CPU.
System Bus:
- A pathway for data transfer among computer components, involving:
  - Data Bus: Carries the data for processing.
  - Address Bus: Specifies the destination for data.
  - Control Bus: Indicates the state of data processing.

Motherboard

The motherboard, or main board, is the primary circuit board connecting various hardware components in a computer system.
It integrates several electronic components, both externally attached and built-in.
