What is Motherboard ?
Motherboard - 
The motherboard, also known as the mainboard or system board, is the primary circuit board in a computer. It serves as the central hub that connects and allows communication between various hardware components, including the CPU (Central Processing Unit), memory, storage devices, expansion cards, and peripherals. The motherboard provides the necessary infrastructure for these components to work together and enables the overall functioning of the computer.
Key features and components of a motherboard include:
1. **CPU Socket:** The socket on the motherboard where the CPU is installed. Different CPUs may require different socket types.
2. **Memory Slots:** Connectors on the motherboard where RAM (Random Access Memory) modules are inserted.
3. **Chipset:** The chipset is a set of integrated circuits that control communication between the CPU, memory, storage devices, and peripheral interfaces.
4. **Expansion Slots:** Slots on the motherboard for connecting expansion cards, such as graphics cards, sound cards, or networking cards.
5. **Peripheral Connectors:** Ports and connectors for various peripherals, including USB ports, audio jacks, HDMI or DisplayPort connectors, and networking ports.
6. **BIOS/UEFI:** Basic Input/output System (BIOS) or Unified Extensible Firmware Interface (UEFI) firmware that provides low-level system control and initializes hardware components during the boot process.
7. **Power Connectors:** Connectors for the power supply unit to provide power to the motherboard.
8. **SATA Connectors:** Ports for connecting SATA (Serial ATA) devices, such as hard drives and SSDs.
9. **CMOS Battery:** A small battery on the motherboard that powers the CMOS (Complementary Metal-Oxide-Semiconductor) chip, which stores system configuration settings.
10. **Form Factor:** The physical size and shape of the motherboard, which determines its compatibility with computer cases.
The motherboard acts as a communication hub, facilitating the transfer of data and instructions between different components. It plays a critical role in determining the overall compatibility, performance, and upgradeability of a computer system. Motherboards are designed to support specific CPU types, memory configurations, and expansion options, so choosing the right motherboard is crucial when building or upgrading a computer.
