Knowing the Key Components of a Desktop Computer

A desktop computer can be used for so many different important purposes, and contains several key components that allow for continuous operations. Whether you're purchasing a new desktop or repairing/upgrading an existing one, knowing the basics on these components can go a long way toward completing your project simply and easily.

At PC Laptops, we're happy to discuss detailed component needs for any of our desktop computer sales or PC repair settings. While you don't necessarily have to be an expert in every single nook and cranny of your machine to have success with it, some general knowledge is often beneficial. Here are the basic components of a desktop computer that you should have a broad idea about.


At the heart of every desktop computer is the central processing unit, or CPU. The CPU handles all of the operations within the machine and works to translate commands entered by the user into an action that can be performed on the PC. It is often referred to as "the brain" of the computer, and it's important to make sure you have a suitable processor for your specific needs.

The CPU is vital because it interacts with many other components within the machine and is responsible for managing data transfers, memory accesses, and other system operations. A good processor can make all of these tasks easier to execute in a timely manner, helping your computer run faster and more efficiently.

The Motherboard

If the CPU is the brain of the desktop computer, many consider the motherboard to be the heart. The motherboard is a large printed circuit board that connects all of the computer's components together. It also provides power to each component, enabling them to communicate and interact with one another in order for your desktop to function properly.

The motherboard will typically have several different slots and ports, as well as a variety of connectors for attaching additional components to the computer. Examples include USB ports, SATA connections, RAM slots, and PCIe slots.

It's important to know that motherboard connections are specific, not generalized. You can't simply plug any component into the motherboard - it must be compatible to ensure that your desktop computer runs smoothly.

The Memory

Another important component of a desktop computer is memory, which can come in two forms: RAM and ROM. Random Access Memory (RAM) is the temporary storage used by programs and applications while they are running on your PC. It is volatile memory, which means that it is lost when the computer is turned off.

ROM, or Read-Only Memory, stores data permanently and can not be changed. It contains instructions for how your computer should start up and operate. The amount of RAM in a desktop computer will determine how many applications and programs can run simultaneously without bogging it down.

Both of these forms of memory are worth considering when it comes to purchasing a computer. Having enough RAM and ROM can make the difference between your machine running smoothly or lagging behind.

The Storage Device

Another important part of a desktop computer is its storage device, which stores all of the user's data. This usually consists of an internal hard drive (HDD) or a solid-state drive (SSD). HDDs are traditional mechanical storage media that use spinning disks to store data. Although they are slower than SSDs, HDDs offer more storage space for a lower price.

On the other hand, SSDs employ memory chips rather than spinning discs and can access data much more quickly than an HDD. However, they come at a higher cost and usually provide less storage space.

CPU Cooler

Keeping things cool is another key component of a desktop computer. The CPU cooler is what keeps the processor from overheating and helps keep your machine running at its maximum efficiency. Without it, your computer's performance could suffer significantly due to heat buildup.

It's important to note that not all CPU coolers are created equal. Some are designed for silent operation while others provide more cooling power. It's important to evaluate your specific needs and choose a CPU cooler that best fits those requirements.

Computer "Hands"

When you hear the term "hands" used when referring to a computer, it's usually referencing the keyboard and mouse. These peripherals provide users with an easy way to input data into their machine and perform various tasks.

The type of keyboard or mouse you choose will be based on your individual preferences, such as how comfortable or ergonomic they feel in your hands. Many people also opt for wireless models that connect to the computer via Bluetooth or other connections, allowing them to move around freely while using their desktop.

The Monitor

Finally, the monitor is a key component of any desktop computer. It displays all of the information that you input into your machine and allows you to view it clearly. The resolution, size, and type of monitor you choose will depend on what kind of visuals you're looking for and how much real estate you need on your screen.

When choosing a monitor, it's important to pay attention to the refresh rate as well. This is how often the monitor refreshes its image and can affect how smooth your visuals appear on-screen.

Overall, having an understanding of these basic components of a desktop computer can help you make informed decisions when it comes to purchasing or repairing one. Knowing what each component does and how it interacts with the other components will ensure that your machine runs optimally.
