Custom PC Basic info

A computer is made up of several key components that work together to process and display information. They all have specific tasks that are ESSENTIAL to the computer working

1. Central Processing Unit (CPU) – The Brain 

The CPU (Central Processing Unit) is the most important component of a computer, responsible for processing instructions, performing calculations, and managing tasks. Think of it as the brain of the system—it executes commands from software and coordinates how other hardware components work together.

Key CPU Features

  • Clock Speed (GHz): Measures how fast the CPU can process data. A higher GHz means faster performance.
  • Cores: CPUs come with multiple cores (e.g., quad-core, octa-core), allowing them to handle multiple tasks at once. More cores = better multitasking.
  • Threads & Hyper-Threading: Some CPUs use hyper-threading to simulate extra cores, improving efficiency.

Types of CPUs

  • Entry-Level (e.g., Intel Core i3, AMD Ryzen 3): Good for basic tasks like web browsing and office work.
  • Mid-Range (e.g., Intel Core i5/i7, AMD Ryzen 5/7): Great for gaming, multitasking, and creative work.
  • High-End (e.g., Intel Core i9, AMD Ryzen 9,): Designed for gaming, content creation, and professional workloads like video editing or 3D rendering.

Why the CPU Matters

A better CPU means faster program execution, smoother multitasking, and improved gaming or creative performance. However, for tasks like gaming, the GPU often plays a bigger role than the CPU alone.

2. Graphics Processing Unit (GPU) – The Artist 

The GPU handles visuals, rendering graphics for games, videos, and design work. High-end GPUs make a big difference in gaming and creative applications.

3. Random Access Memory (RAM) – The Short-Term Memory 

RAM temporarily stores data your PC is actively using, allowing for faster access and multitasking. More RAM means smoother performance when running multiple programs.

4. Storage (HDD/SSD) – The Long-Term Memory 

  • Solid-State Drives (SSD) are fast, durable, and improve boot times and loading speeds.
  • Hard Disk Drives (HDD) offer more storage at a lower cost but are slower.

5. Motherboard – The Nervous System 

The motherboard connects all components, allowing them to communicate. It has slots for the CPU, RAM, GPU, and storage.

6. Power Supply Unit (PSU) – The Heartbeat 

The PSU converts electricity from the outlet into usable power for the computer. A reliable PSU ensures stable performance and prevents damage.

7. Cooling System – The AC Unit 

Cooling keeps the PC from overheating. This includes:

  • Fans (air cooling)
  • Heat sinks (metal components that absorb heat)
  • Liquid cooling systems (for high-performance PCs)

8. Case – The Body 🏠

The case houses and protects all the components. It comes in different sizes and styles, often with cooling features and RGB lighting for aesthetics.
