The motherboard also provides power and cooling to these components, ensuring they operate smoothly. Different motherboards support different types of CPUs and RAM, so choosing the right motherboard is crucial when building or upgrading a computer.

Then there's memory, specifically Random Access Memory (RAM). RAM is the computer's short-term memory, used to store data and instructions that the CPU needs to access quickly. Unlike storage devices like hard drives or SSDs, RAM is volatile, meaning it loses its data when the power is turned off. The more RAM you have, the more programs and data your computer can handle simultaneously without slowing down. For example, if you're running multiple applications or working with large files, having sufficient RAM can make a huge difference in performance.

Last but not least for this section, let's talk about storage devices. These are used to store data persistently, even when the computer is turned off. Common types of storage devices include hard disk drives (HDDs) and solid-state drives (SSDs). HDDs use spinning platters to store data magnetically, while SSDs use flash memory. SSDs are generally faster and more durable than HDDs, but they can also be more expensive. The storage capacity of a drive determines how much data you can store, including your operating system, applications, and personal files. In recent years, SSDs have become increasingly popular due to their speed and reliability, making them a preferred choice for many users.
