4. Input components An input device is a hardware component that allows users to send data, instructions, or control signals to a computer or digital system. These devices serve as the bridge between the user and the computer, enabling communication and interaction with software and hardware by converting human actions or environmental data into signals that the computer can interpret and process Key Features of Input Devices Input devices allow users to feed data or commands into a computer, such as text, audio, images, or other forms of information. They convert user information or physical conditions into digital signals for processing by the computer system. Examples include the keyboard for typing, mouse for navigation, scanner for digitizing documents, microphone for recording audio, and touchscreen for direct interaction. Common Examples Keyboard: Used for typing text and commands. Mouse: Pointing and clicking navigation device. Scanner: Converts physical documents into digital form. Microphone: Captures audio input for the system. Touchscreen: Registers touch-based direct input. Webcam/camera: Provides video or image input

5. Processing components Examples Of Components Within CPU Arithmetic Logic Unit (ALU ) :   Performs all arithmetic and logical operations within the CPU, such as addition, subtraction, comparison, and bitwise operations . Control Unit(CU ) : Directs all operations in the CPU by fetching, decoding, and executing instructions, and controlling data flow between other components. Registers : Small, fast memory units inside the CPU that temporarily hold data, instructions, and addresses while processing occurs . Bus Interface : Manages communication between the CPU and main memory or other components . Clock : Synchronizes and controls the timing of CPU operations, ensuring all tasks happen in a precise order. CPU(Central Processing Unit) Is Responsible For All The Process Inside A PC

6. Output components Output components in a computer are hardware devices that receive processed data from the computer and convert it into forms that humans can perceive and understand, such as visuals, sounds, or printed materials. These devices present the results of computations and operations performed by the computer in various formats, allowing users to interact with and utilize the information effectively Types and Functions Output devices may be categorized based on their output form: Visual Output Devices. Audio Output Devices. Print Output Devices . Tactile Output Devices.

7. Output components Common Output Components Monitor:  Displays text, images, videos, and graphical interfaces visually on a screen. Printer:  Produces physical hard copies of documents, images, or graphics on paper. Speakers:  Output audio signals such as music, voice, and other sounds. Headphones:  Provide personal audio output directly to the user's ears. Projector:  Projects images or videos onto a larger surface for presentations or viewing by larger audiences

8. Memory components  in computers (also known as "primary storage") are used to temporarily hold data and instructions that the CPU needs while performing tasks. These are typically fast but volatile: they lose their contents when power is lost. Memory components Purpose:  Hold data and instructions currently being used by the CPU for rapid access, making the system run smoothly and efficiently.

9. Types of Memory Components Random Access Memory (RAM) Description:  Temporarily holds data and instructions for active processes and tasks. Features: Volatile (data lost on power-off) Directly accessible by CPU Essential for multitasking and smooth performance Cache Memory Description:  Tiny but ultra-fast memory located close to or inside the CPU. Stores frequently used data/instructions to speed up processing. Features: Very fast, but much smaller in size than RAM Often divided into L1, L2, and L3 levels based on proximity to CPU and size Read-Only Memory (ROM) Description:  Stores permanent instructions needed for basic computer functions (such as starting up the computer). Features: Non-volatile (data doesn't erase on power-off) Typically unchangeable under normal operation, but some types can be updated with special procedures

10. Storage components Storage components  are hardware devices used to store data and information for immediate or future use. They keep data even when the computer is turned off (non-volatile storage). Purpose:  Store large amounts of data for long-term safe keeping, retrieval, and transfer.

11. Main Types Secondary Storage Examples:  Hard Disk Drives (HDDs), Solid-State Drives (SSDs), USB Flash Drives, Optical Discs (CDs, DVDs), Memory Cards. Features: Used to store operating systems, files, applications, and media. Data remains intact even after shutdown. Usually offers very large capacity but is slower than memory (RAM). Not accessed directly by the processor; data must first be copied into memory before processing. Tertiary Storage Examples:  Tape drives, robotic data libraries (used mostly in data centers for backup and archiving). Features: Used for long-term archiving and backups. Often requires manual or automated mounting. Storage components

12. Aspect Memory (RAM, Cache, ROM) Storage (HDD, SSD, USB, CD/DVD) Purpose Stores data temporarily for active processing Stores data permanently for long-term access Volatility Volatile (data lost when power is off; except ROM) Non-volatile (data stays after power off) Speed Much faster (supports instant access for CPU tasks) Slower to access compared to memory Capacity Smaller capacity (usually MB or GB range) Larger capacity (can be hundreds of GBs to TBs) Cost More expensive per GB More affordable per GB Role Supports running programs and active processes Stores files, applications, operating systems Access by CPU Directly by CPU (for immediate use) Data must be loaded into memory before processing Data Lifespan Short-term, wiped with system shutdown Long-term, persists through power cycles Difference between memory and storage components

13. motherboard A motherboard is the main printed circuit board (PCB) in a computer that acts as the foundational platform connecting and allowing communication between all the crucial components like the CPU, RAM, storage devices, and expansion cards. It functions as the central backbone through which power and data signals flow between these parts, enabling the entire computer system to operate cohesively. Key Functions of a Motherboard Connecting components:  It provides slots, sockets, and ports where hardware parts like the processor, memory, and peripherals are mounted and connected. Power distribution:  It channels electricity from the power supply to all components installed on it. Data transfer:  It contains circuits and buses that transfer data and instructions between CPU, memory, storage, and input/output devices. Expansion:  It offers expansion slots ( PCIe , PCI) to add additional hardware such as graphics cards, sound cards, or network adapters . System control:  Contains essential chips like the chipset ( northbridge and southbridge ) which control data flow and peripheral device communication.

14. motherboard Main Components on a Motherboard CPU socket:  The slot where the central processing unit is installed. RAM slots:  Slots to install memory modules. Chipsets (Northbridge & Southbridge):  Manage communication between CPU, memory, and peripherals. Expansion slots:  For graphics cards and other expansion hardware. Power connectors:  To receive power from the power supply. BIOS/UEFI chip:  Stores firmware instructions to boot the system. Input/output ports:  USB, audio, network, and display ports to connect external devices.

16. Power supply unit ( psu ) A Power Supply Unit (PSU) in a computer is a critical hardware component that converts the high-voltage alternating current (AC) from the mains electricity supply into low-voltage, regulated direct current (DC) power that the computer's internal components can use safely and efficiently Important Components in a PSU: Transformer:  Adjusts and steps down the input AC voltage. Rectifier:  Converts AC to DC power. Capacitors:  Smooth out voltage and reduce fluctuation. Voltage Regulators:  Maintain steady and precise voltage levels. Cooling Fan/System:  Prevents overheating of the PSU. Protection Circuits:  Safeguards against electrical faults.
