Essential Components of Computer Hardware
Central Processing Unit (CPU)
The CPU, often referred to as the brain of the computer, orchestrates the operations of all other components. It processes instructions and performs calculations, playing a pivotal role in the overall performance of the system. Brands like Intel and AMD dominate this space, each offering a range of processors catering to different needs.
Upgrading the CPU can lead to better performance, but isn’t always practical because it may require a compatible motherboard (which is a separate upgrade).
Motherboard
The motherboard acts as the backbone, connecting all components of the computer. It houses the CPU, RAM, and other crucial elements, facilitating communication between them. The choice of motherboard impacts the computer’s compatibility with other components and overall functionality.
Computer Memory
When people refer to “computer memory” they’re either talking about your RAM or your Storage space – such as a Hard Drive or SSD. Memory is a key component of a system that determines how many tasks your computer can handle simultaneously and/or how many files and what capacity of files you can hold on to. Upgrading RAM is one of the easiest and most cost-effective ways to boost your computer’s performance.
Random Access Memory (RAM)
RAM is where the computer stores data for quick access. It’s a temporary storage that holds information currently in use, allowing for swift retrieval and processing. The amount and speed of RAM significantly affect the computer’s ability to multitask and handle demanding applications.
Adding more RAM can dramatically improve performance, especially for resource-intensive tasks like gaming or video editing.
Storage Solutions: HDDs vs. SSDs
Hard Disk Drives (HDDs) and Solid State Drives (SSDs) are the two primary types of storage devices. HDDs, the traditional choice, offer ample storage at a lower cost but are slower and more prone to physical damage. SSDs, on the other hand, provide faster data access and are more durable, albeit at a higher price point.
Hard drives and solid-state drives (SSDs) are indispensable for backing up data or expanding a computer’s storage capacity. They offer portability and the peace of mind that comes with having a secure copy of your important files.
SSDs: The New Standard in Storage
Solid State Drives (SSDs) offer faster data access speeds compared to traditional hard drives. Upgrading to an SSD can significantly reduce boot times and improve overall system responsiveness.
Graphics Card (GPU)
Graphics Processing Units (GPUs) – also referred to as Video Cards – are critical for rendering images, videos, and animations. Upgrading your GPU can enhance your computer’s ability to handle graphic-intensive tasks like gaming or 3D modeling. Choosing your graphics card is critical when it comes to gaming and professional graphic design.
In a typical build, the graphics card will be the most expensive component and the processing power it can deliver is what will affect your ability to play certain games and what quality / frame-rates you get.
Monitor
A monitor is what you visually look at when using your computer. The monitor works in tandem with the graphics card to display the output. The resolution, refresh rate, and panel technology of monitors are key factors in determining image quality.
They range from basic models for everyday use to high-end displays with features like 4K resolution and color accuracy for professionals.
The Importance of a Good Computer Monitor
A high-quality computer monitor can make a significant difference in how you interact with your computer. Monitors with higher resolutions, faster refresh rates, and better color accuracy can improve productivity and enhance the gaming and viewing experience.
Power Supply
The power supply unit (PSU) is responsible for providing stable power to all components. Its capacity and efficiency rating should match the demands of the system. Choosing a quality power supply that meets and exceeds your requirements is a critical aspect of building your system. You want to give yourself a 20-30% buffer over your basic power needs to account for future expansion and changes that may occur.
It’s always a good idea to stick with the quality brands in PSUs to avoid issues that “cheap” ones can cause. Here’s a list of the best of the best:
- Seasonic: Renowned for their high quality, reliability, and long-lasting performance. Offers a wide range of PSUs from budget-friendly to high-end models with 80+ certification levels.

Surge Protectors and UPS
Surge protectors and Uninterruptible Power Supplies (UPS) safeguard your computer and accessories from power surges and outages, preventing data loss and hardware damage.
Cooling System
Overheating can lead to hardware failure. That’s why your cooling systems, including fans and liquid cooling solutions, are essential for maintaining optimal temperatures. It’s critical to make sure your CPU has a cooling fan on it so a lot of focus is put on that (and for good reason). Beyond just the CPU, however, the overall health of your system can be impacted by the airflow and cooling inside the case so cooling is a big deal when building & designing your PC.
Computer Accessories: Enhancing the Experience
Computer accessories like keyboards, mice, speakers, and webcams can significantly enhance your computing experience. Upgrading these peripherals can lead to better ergonomics, increased functionality, and a more enjoyable user experience.
Keyboards and Mice: Tools for Input
The choice of keyboard and mouse can significantly impact user experience. Mechanical keyboards, known for their tactile feedback, are popular among gamers and typists. Ergonomic mice and keyboards are designed to reduce strain during prolonged use, a crucial aspect for professionals.
They come in various forms: wired, wireless, ergonomic, compact, gaming-oriented, and more. The right set can significantly impact your comfort and productivity.
Computer Mouse
A computer mouse is an essential input device, allowing users to navigate and interact with their computer’s interface. Over the years, it has evolved from a simple two-button device to sophisticated models featuring multiple buttons and scroll wheels for enhanced functionality.
Gaming Keyboards
Gaming keyboards are designed for precision and durability. Features like programmable keys, RGB lighting, and adjustable DPI settings on mice make a significant difference in gaming performance and personalization.
