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.
- A pathway for data transfer among computer components, involving:
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.
