Form Factor:
- Size and shape of the motherboard, determining the type of computer case it can fit into. Common form factors include ATX, microATX, and mini-ITX.
Socket:
- Connects the CPU to the motherboard, determining the compatible CPU models. Common sockets include LGA (Intel) and AM4 (AMD).
Chipset:
- Controls the communication between the CPU, memory, storage, and other components. It determines features such as PCI Express slots and SATA ports.
BIOS (Basic Input/Output System):
- Contains firmware that stores boot instructions, system settings, and diagnostic routines.
Memory Slots:
- Accommodate RAM modules, which store short-term data. Slots have specific types (DDR4, DDR5) and memory speeds.
Expansion Slots:
- Allow the installation of additional components, such as graphics cards, sound cards, and network adapters. Common slots include PCI Express, PCI, and M.2.
Storage Connectors:
- Connect storage devices such as hard disk drives (HDDs), solid-state drives (SSDs), and optical drives. Common connectors include SATA, M.2, and NVMe.
Power Connectors:
- Supply power to the motherboard and its components. Typically include a 24-pin ATX connector and 4/8-pin CPU connector.
Cooling System:
- Mounts heatsinks and fans to dissipate heat from the CPU and other components.
Integrated Peripherals:
- May include built-in components such as audio, network, and USB ports.
Back Panel Connectors:
- Provide ports and connectors for external devices and peripherals, such as USB, Ethernet, HDMI, and audio jacks.
Other Features:
- CMOS battery to maintain BIOS settings
- Jumpers or BIOS switches for configuration
- RGB headers for connecting lighting devices
