Study Notes
Applications of Computers in Various Fields
- E-commerce: Utilizes electronic mail, video conferencing, online shopping, and electronic banking.
- Education: Enhances study methods, simplifies complex concepts, and provides vast global information through internet access.
- Medicine & Healthcare: Supports patient monitoring, maintains patient records, aids in diagnosis, facilitates hospital administration, and manages medical histories and life support systems.
- Entertainment: Offers diverse media consumption and gaming options.
- Engineering/Architecture/Manufacturing: Incorporates computer-aided design (CAD) and precision manufacturing.
Computer System Components
- Central Processing Unit (CPU): Acts as the brain of the computer and performs processing of instructions and data, controlling input and output operations.
- Input Unit: Accepts instructions and data.
- Output Unit: Displays results to the user.
- Registers: Temporary storage locations within the CPU.
Characteristics of Computers
- Speed: Operates at immense speeds compared to human processing, measured in MegaHertz (MHz).
- Accuracy: Executes tasks with high precision; relies on correct input and design (GIGO principle: Garbage In, Garbage Out).
- Reliability: Performs consistently without failure; operates autonomously without human intervention.
- Diligence: Free from fatigue or lack of concentration, capable of continuous operation.
- Versatility: Handles diverse tasks simultaneously including computations and graphics.
- Storage Capability: Can store extensive data; loss or deletion is user-controlled.
- No Intelligence (IQ): Does not possess self-directed thinking; executes predefined instructions.
- No Feelings: Lacks emotions or sensory perceptions.
Generations of Computers
- First Generation (1940-1956): Utilized vacuum tubes, magnetic drums, and machine language; known for large size and high power consumption.
- Second Generation (1956-1963): Introduced transistors and magnetic core storage; programming shifted to assembly language and simpler input/output processes.
- Third Generation (1964-early 1970s): Integrated circuits replaced transistors, increasing speed and decreasing size.
- Fourth Generation (1970s-present): Microprocessors and personal computers became prevalent, revolutionizing computer use.
- Fifth Generation (still developing): Focus on artificial intelligence and advanced problem-solving techniques.
