Study Notes
Computer System
- Definition: A computer system is a combination of hardware and software designed to process data and perform tasks to meet user needs.
- Characteristics: Includes speed, accuracy, automation, versatility, and storage capacity.
- Applications: Used in various sectors such as education, healthcare, business, gaming, and scientific research.
- Functions: Perform inputs, processing, storage, and output of data.
Basic Organization of a Computer
- Composed of input devices, processing unit (CPU), memory (RAM/ROM), storage, and output devices.
- Input Devices: Keyboard, mouse, scanners; facilitate user interaction with the computer.
- Output Devices: Monitors, printers; display or produce results.
CPU and Its Components
- Central Processing Unit (CPU): The brain of the computer, responsible for executing instructions and processing data.
- Components:
- Arithmetic Logic Unit (ALU): Performs arithmetic and logical operations.
- Control Unit (CU): Directs operations of the CPU and coordinates between hardware components.
- Registers: Small storage locations that hold temporary data and instructions.
Units of Memory
- Memory refers to storage required to hold data and instructions.
- Types:
- Volatile memory (e.g., RAM) loses data when power is off.
- Non-volatile memory (e.g., ROM, flash memory) retains data without power.
- Capacity is measured in bytes (KB, MB, GB, TB).
Control Unit
- Manages and coordinates the activities of the computer.
- Interprets instructions from programs and sends signals to execute them.
- Ensures proper timing for all processes to occur, ensuring the flow of data within the CPU.
Types of Computers Based on Principles of Operation
- Analog Computers: Handle continuous data; used in applications like simulations.
- Digital Computers: Operate on discrete values; applicable for general-purpose computing.
- Hybrid Computers: Combine features of both analog and digital computers for specific tasks.
Types of Computers Based on Configuration
- Supercomputers: Extremely powerful machines used for complex calculations such as weather forecasting.
- Mainframe Computers: Handle large volumes of data for enterprises and institutions.
- Personal Computers (PCs): Designed for individual use; accessible and versatile.
- Workstations: High-performance PCs optimized for technical or scientific applications.
- Servers: Provide resources and services to other computers over a network.
Overview of Communication Technologies
- Encompasses tools and systems that enable data transmission over distances.
- Types:
- Wired communication (e.g., fiber optics, Ethernet cables) for reliable connections.
- Wireless communication (e.g., Wi-Fi, Bluetooth) for flexibility and mobility.
- Technologies support data transfer, internet connectivity, and networking across devices.
AI Basics
- Artificial Intelligence (AI): Simulation of human intelligence processes by machines, especially computer systems.
- Key Components: Machine learning, natural language processing, and robotics.
- Applications: Widely used in areas such as speech recognition, image processing, and autonomous systems.
