The 5 Most Essential Computer Components

In Hong Kong’s fast-paced technological landscape, understanding your computer’s inner workings is crucial for maintaining peak performance and longevity. Just as we need to take care of our health, our computers require attention to ensure they run smoothly. While PCs don’t need much sustenance beyond a consistent power supply, they’re composed of durable components that can face issues if compromised.

As responsible desktop and laptop users in Hong Kong, it’s beneficial to familiarize yourself with the internal hardware that powers your computer’s processes. With this knowledge, you can easily identify potential reasons for your PC slowing down, enabling you to troubleshoot issues without the need for a trip to a computer store, saving both time and money in our bustling city.

Imagine your computer as a living organism, with its internal components functioning as vital organs. Each part plays a unique role in ensuring your PC runs effectively, and each component is crucial in its own way.

In this article, we’ll explore the 5 most important of these components. Then, we’ll introduce you to some of HP’s best desktops available in Hong Kong, featuring top-quality specifications.

5 most important components of your computer

To maintain your PC’s prime condition and enjoy uninterrupted use, regular servicing and timely upgrades are essential. Like any electronic device, computer hardware can deteriorate with constant use.

Computers can slow down for various reasons, and often, you can resolve issues without tampering with delicate components. However, for more critical problems, an upgrade is often the best solution. Here are the 5 major computer components you should be familiar with:

1. Motherboard

The motherboard is the foundation of any computer components list. It’s the primary circuit board that holds all the hardware in place. Every PC, from dedicated workstations to personal notebooks, has one. A robust motherboard offers numerous slots for installing multiple computer components such as RAM and graphics cards.

Motherboards come in different form factors, which encompass general specifications including circuitry arrangement, overall size, and number of ports. Only specific motherboard models can fit into certain computer cases or chassis, especially for customizable desktops.

Laptops use specialized motherboards with much of their built-in hardware permanently soldered onto the circuits. This design accommodates the laptop’s smaller frame and lighter build, with only certain parts like RAM and storage being upgradeable.

A damaged motherboard can cause a PC to cease functioning fully. Given the complexity of the circuitry and wiring, a faulty motherboard can instantly halt your computer’s operation and potentially harm other components. While desktop motherboards are easily replaceable, the same isn’t true for laptops, which may require purchasing a new device.

2. Central Processing Unit (CPU)

The central processing unit (CPU), commonly referred to as the processor, is the ‘brain’ of your computer. It solves all the sophisticated algorithms and performs the programming your computer executes while running programs or applications.

Modern processors typically contain multiple CPUs to achieve quicker processing speeds, ensuring faster response times when using software or browsing the web. These are called multi-core processors, with each CPU designated as one processing core.

For instance, the high-end Intel® Core™ i7-13700H processor has 14 independent cores working together to handle computing tasks, allowing you to perform intensive work without overstressing your computer.

While it’s possible to squeeze more power from your CPUs through overclocking for slight performance boosts, this comes with risks that might damage your processor. Remember, a PC cannot function properly with an impaired processor, even if other components are working normally.

3. Graphical Processing Unit (GPU)

The graphical processing unit (GPU) is responsible for handling graphical operations and advanced imagery. A GPU is essential for your computer to read and reproduce graphical representations and effects, which are prevalent in almost every form of media today.

Some high-spec CPUs have basic GPUs embedded in them, especially in premium laptops focused on lightweight mobility and use. However, the most powerful GPUs are primarily used for video gaming, capable of handling immense 3D-graphics loads to maintain smooth frame rates and lag-free experiences.

During gaming, the CPU and GPU work in tandem. The GPU manages the heavy lifting in terms of on-screen graphics and fidelity, while the CPU runs the programming that works behind the scenes, such as data processing and in-game statistics.

A malfunctioning GPU can lead to numerous problems, including the dreaded black screen of death. The current global shortage of GPU chips makes losing your GPU particularly problematic.

4. Random Access Memory (RAM)

Computers utilize different forms of memory to store information and data. The most commonly discussed is random-access memory (RAM). A RAM device keeps important, currently-used data and codes on standby, loading them instantly when respective programs or apps are opened.

RAM is a volatile type of memory, meaning all stored memory is refreshed after turning off the PC. This allows the device to quickly absorb new data immediately during the next session, enabling quicker loading processes.

Most mainstream computers, including compact laptops, can be upgraded with more RAM by installing a better RAM device or RAM stick that offers larger storage capacity. However, depending on your computing activities, you might not utilize all available RAM, so it’s important to understand how much RAM is ideal for your PC based on its primary use (work, gaming, etc.).

While a damaged RAM stick might not necessarily prevent your computer from working, it will hinder its performance over time, resulting in program crashes, unexpected decreases in available RAM, and boot failures, among other issues.

5. Storage device

A storage device provides memory for installing programs and saving files. Unlike RAM, a storage device’s content is secured in non-volatile memory, meaning that data is saved permanently inside its memory bank, preserving it even after you turn off the PC (unless manually deleted or uninstalled).

PCs commonly use two types of internal storage devices: hard disk drives (HDDs) and solid-state drives (SSDs). HDDs are the cheaper option but suffer from slower transfer speeds, while SSDs are their superior counterparts but are more expensive. These devices are attached to your computer using dedicated SATA cables, replaced by SAS cables for large servers and workstations.

Other secondary storage devices exist, such as USB flash drives and portable HDDs. However, these peripherals are not installed inside computers. Instead, they connect to the PC via alternative channels like USB ports or external disk drives, depending on the specifications.

Even though storage devices do not impact your computer’s boot-up process, start-up programs like Google Chrome or Microsoft Word are loaded directly from your HDD or SSD. A damaged storage device can interrupt this process, potentially corrupting your files. If this occurs, you will need to replace your hard drive immediately, sometimes requiring a complete system reformat or Windows reinstall, which can be a significant inconvenience.
