Basic Components of a PC
- CPU (Central Processing Unit): A complex integration of millions of transistors that execute instructions and manipulate data. Components include the memory unit, control unit, ALU (Arithmetic Logic Unit).
- Secondary Storage: Examples are magnetic tape, magnetic disks, CDs, etc.
- Input Unit: Examples are keyboard, mouse, light pen, joystick, etc.
- Output Unit: Examples are monitor, printer, plotter, etc.
- Peripheral Devices: Devices connected to the system unit that handle input, output, auxiliary storage, and communication.
Computer Hardware
- System unit: Contains the electronic components for processing and storing data and instructions (CPU, primary memory, system board).
- Peripherals: Attached to the system unit to handle input, output, auxiliary storage, and communication. I/O devices are used to interact with the computer system and allow outside interactions.
Central Processing Unit (CPU)
- The most essential component in a computer. A CPU is a complex integration of electronic transistors which execute program instructions and work with data.
- Intel 10-Core Xeon processors contain over 2.6 billion transistors.
- Processor speed is typically measured in Megahertz (MHz) or Gigahertz (GHz). Higher hertz indicates faster processing.
CPU : Control Unit, Arithmetic Logic Unit, Registers
- Control Unit: Directs data and instruction flow within the processor and memory.
- Arithmetic Logic Unit (ALU): Performs mathematical and logical calculations.
- Registers: Special transistors that store data and instructions while they are being manipulated, and high-speed memory (cache) stores frequently used data and instructions.
Memory
- Primary Memory: RAM and ROM.
- Secondary Memory/Auxiliary Memory: Storage for long-term data (magnetic disks, etc).
Input and Output Devices
- Input Devices: Used to transfer data and user commands into the computer system (e.g., keyboard, mouse, joystick).
- Output Devices: Display results of input data or signals after processing (e.g., monitor, printer, plotter).
- I/O Devices: Allow interaction between the computer system and the outside world. I/O devices are also called I/O modules that connect to devices (e.g., speakers connected to an audio card, which is itself part of the system).
