What are the uses of various components of motherboard of a computer? List at least four output devices and ports to which these devices can be connected. Explain the characteristics of these output devices and ports.

Uses of Various Components of a Motherboard

A motherboard is the central circuit board of a computer that connects all components and allows communication between them. Its key components and their uses are:

1. Central Processing Unit (CPU) Socket

• Use: Provides the physical interface to install the processor. The CPU executes instructions and performs calculations.

2. RAM Slots (Memory Slots)

• Use: Holds the Random Access Memory (RAM) modules that temporarily store data and instructions for quick access by the CPU.

3. Chipset

• Use: Manages data flow between the CPU, memory, storage, and peripheral devices. Divided into Northbridge (handles high-speed communication) and Southbridge (handles I/O functions).

4. Expansion Slots (PCIe, PCI)

• Use: Allow connection of additional hardware like graphics cards, sound cards, or network adapters.

5. Storage Connectors (SATA, NVMe)

• Use: Facilitate connection to storage devices like HDDs, SSDs, and optical drives.

6. Power Connectors

• Use: Distribute power from the power supply to components like the CPU, GPU, and peripherals.

7. I/O Ports and Headers

• Use: Enable connection to external devices like USB drives, audio systems, and monitors.
