Published: May 23, 2025
Have you ever wondered what Computer Server Hardware is? That keeps websites running, files stored, or apps working around the clock?
A computer server is a powerful machine designed to manage data, run applications, and connect users over a network.
Unlike a regular home computer, it’s built to handle heavy tasks and operate nonstop.
Understanding server hardware components is important whether you work in IT, run a business, or enjoy learning about technology.
Knowing what goes on inside a server — from CPUs and RAM to storage and network parts — helps you make better decisions, solve issues faster, and even plan upgrades more confidently.
In this post, we’ll break down the basics of computer server hardware, explore server computer components, and give you a clear look at the server equipment that powers modern networks.
Let’s get started.
What is a Computer Server and Computer Server Hardware?
A computer server is a special type of computer that stores, manages, and shares data with other devices.
While it looks similar to a regular PC on the outside (sometimes even smaller or bigger), what makes it different is how it’s used and what’s inside.
Servers are built to:
- Handle large amounts of data
- Stay on 24/7 without slowing down
- Support many users or devices at once
For example, when you visit a website, upload a file, or stream a video, you’re connecting to a server. That server sends the information you need — fast and reliably.
There are many types of servers depending on the job they do, like:
- Web servers (host websites)
- File servers (store and share files)
- Database servers (manage data for apps and websites)
- Mail servers (send and receive emails)
Each of these runs on different server hardware components, which work together to keep things running smoothly.
Computer server hardware refers to all the physical parts and components that make up a server.
These include things like the motherboard, CPU, memory (RAM), storage drives, network cards, power supplies, and cooling systems.
Together, these hardware components work to process, store, and manage data, allowing the server to perform tasks and provide services to other computers or devices on a network.
In the next section, we’ll look at why it’s useful to understand these hardware parts, especially if you work in tech, run a business, or just enjoy learning how things work.

Major Components of Server Hardware
Now that you have a basic idea of what a server does, let’s open it up and see the key parts inside.
Knowing these hardware parts helps you understand how servers work, how to fix problems, and how to improve their performance.
Here’s a detailed look at the most important server hardware components:
Motherboard
The motherboard is the main circuit board in a server.
It connects and allows communication between all other parts, like the CPU, memory, storage drives, and network cards.
Without the motherboard, these parts wouldn’t be able to work together.
It’s often called the backbone of the server and one of the main hardware components of a computer.
It also holds slots and ports for expansion, meaning you can add or upgrade parts as needed. Learning about the motherboard is one of the first steps in understanding hardware basics.
CPU (Central Processing Unit)
The CPU is often called the brain of the server. It processes all the instructions and data the server needs to work.
When a server receives requests, like loading a webpage or running an application, the CPU handles those tasks.
In fact, when you ask which hardware component processes data, the answer is always the CPU.
Servers often use specialised CPUs that are more powerful than typical desktop processors because they need to manage many tasks at once, often for multiple users.
RAM (Memory)
RAM, or random-access memory, is the temporary workspace for the server. It stores data that the CPU needs to access quickly while running programs and handling tasks.
The more RAM a server has, the better it can handle many tasks at the same time without slowing down.
This is especially important for servers running databases or multiple applications.
RAM works alongside the storage components of a computer, but unlike storage drives, RAM is fast and temporary—it clears out when the server restarts.
Storage Drives (SSD/HDD)
Servers use storage drives to save data permanently. There are two main types: traditional hard disk drives (HDDs) and faster solid-state drives (SSDs).
HDDs are cheaper and offer large storage space, while SSDs are faster and more reliable but usually cost more. Many servers use a mix of both to balance speed and capacity.
These drives are part of any good hardware parts list and are critical for tasks like running databases, storing files, and hosting websites.
In fact, if you’re looking for hardware for a database server, fast and reliable storage drives are a must.
Network Interface Cards (NICs)
The network interface card connects the server to the network.
It allows the server to send and receive data to and from other computers, devices, or the internet.
Without NICs, a server wouldn’t be able to communicate or share information, making them one of the essential hardware components of a network.
Servers often have multiple NICs for faster and more reliable network connections.
Power Supply Unit (PSU)
The power supply unit provides electrical power to all server components.
It converts the electricity from a wall outlet into the right kind of power needed by the CPU, motherboard, drives, and other parts.
Because servers run continuously, the PSU must be reliable and efficient.
If you ever need to replace or upgrade a PSU, you can find them at a server supply store or by searching for a server supply store near you.
Cooling Systems
Servers generate a lot of heat because they run 24/7 and work hard. That’s why they have special cooling systems to keep temperatures down.
Most servers use multiple fans that pull air through the case. Some high-end servers use liquid cooling for better heat management.
Cooling parts are included in server rack parts and are critical server parts to prevent overheating, which can cause damage or slow performance.
RAID Controllers (Optional)
RAID controllers manage multiple storage drives to improve performance and data safety. RAID stands for Redundant Array of Independent Disks.
By combining drives in different ways (called RAID levels), a server can keep working even if one drive fails or speed up data access.
While not all servers need RAID, it’s common in business environments where advanced storage management is important.
These components are the building blocks of every server. Understanding them will help you troubleshoot issues, choose the right hardware, or plan for upgrades that fit your needs.
