What Is a PC (Personal Computer)?

In the world of computers, personal computers (PCs) play a huge role. Whether for work, communication, or entertainment, personal computers are an essential piece of technology for millions of people all over the world.
But what is a PC exactly? How do they work? How do you choose the right one? In this guide, we'll cover all that you need to know about personal computers, including types, uses, and maintenance tips to ensure your PC lasts as long as it can.

What is a PC computer?

A PC, or personal computer, is a versatile computing device made for individuals. The term "personal" distinguishes PCs from mainframe computers or supercomputers, which are typically used by large organizations for complex tasks that require a large amount of computing power.

How does a PC work?

In order for PCs to work, many components have to come together to perform functions. These components include a central processing unit (CPU), a hard drive for storage, memory or random access memory (RAM), and input and output devices. These input and output devices include a keyboard, a mouse, a monitor, and a motherboard that connects and controls all of these components.

The motherboard is in charge of controlling inputs, processing data, storing data, and providing outputs. For example, when you interact with your PC by clicking on an application to launch it, the input data of your click goes to the CPU for processing. Then, the CPU executes the instructions stored in the RAM and retrieve the data from storage devices as needed. Once executed, the output displays on the screen for you to see as the PC launches the application.

The operating system - Windows, macOS, or Linux - acts as a go-between from the user and the hardware. It runs applications, manages resources, facilitates communication, and provides an easy-to-use visual interface for you to interact with.

Types of personal computers and what they're used for

There are various types of PCs out there to choose from, each with their own benefits and uses. Here are the most common.

Desktop PCs

Desktops are the original, most traditional type of PC. They consist of computer components housed within a tower that is separate from the input and output devices like the mouse, keyboard, and monitor. A desktop PC is the best for tasks that require a lot of computing power, like graphic design, video or audio editing, software development, and gaming.

Laptop PCs

Laptop computers are portable versions of desktop computers. They take all the components from the tower and combine them into one single unit that contains the keyboard, trackpad, and screens. Laptops are great for people who need mobility without sacrificing too much performance. They are most commonly used for work, school, web browsing, video streaming, and light gaming.

All-in-one PCs

All-in-one (AIO) PCs take the components of a desktop tower and put them into one single unit within a high resolution monitor. People like AIO PCs for their sleek and space-saving design. They're suitable for environments where space is limited, or for users who don't like the bulky look of the desktop tower. You can use them for the same tasks that desktops are typically used for.

Mini PCs

Mini PCs are similar to desktops - the difference is that the unit housing the components is much smaller. Minis offer performance similar to desktops while offering the size advantages of all-in-ones. The main benefit of miniature PCs is that they offer flexibility to update the monitor whereas AIO PCs don't.

Gaming PCs

Gaming PCs are personal computers specially designed for gaming performance. They have powerful CPUs, graphics cards, high-speed memory, and fast storage so that they can deliver the most immersive and high-quality gaming experiences. If you need the best performance for your video games, a gaming PC is essential.

Note that gaming computers are typically desktops, but they also make gaming-specific laptops.

Workstation PCs

Workstations are computers with high-performance designed for working professionals in fields like engineering, animation, scientific research, architecture, and data analysis. They offer the most processing power, graphic capability, and memory capacity of any PC type.

What is the difference between a Mac and a PC?

While both Macs and PCs are technically personal computers, they are often distinguished by the different ecosystems they belong to. In the general lexicon, "PC" refers to all computers that run operating systems like Windows operating system, Linux, or Chrome OS. Many different manufacturers make these personal computers, including HP, Dell, and Sony.

"Mac," on the other hand, refers to computers manufactured specifically by Apple that run the macOS operating system. While Macs are a subset of PC, they are usually discussed separately due to their unique features, design aesthetics, and ecosystem associated only with Apple products.

Macs are known for their build quality and minimalist design. Personal computers, on the other hand, come in a variety of designs and offer flexibility for user preferences, budget, and customization. When choosing between Mac and PC, consider budget, OS preferences, hardware specs, and ecosystem integration.

Ultimately, the decision comes down to preferences. Both options offer powerful tools to enhance your experience and boost your productivity and creativity.

How to choose a type of PC

When picking a PC, you should consider the following factors.

  • Tasks. Figure out what you'll spend the majority of your time doing on your PC, whether it's work, streaming, web browsing, or gaming.
  • Performance specs. Compare personal computers across components, including CPU, GPU, RAM and storage options. For more demanding tasks like video editing, programming, gaming, opt for higher specs. If you're just going to be web browsing or watching Netflix, higher specs are mostly unnecessary.
  • Size and space. Choose a size that fits your space and mobility needs.
  • Budget. Start out with a budget and prioritize features and performance based on your budget. To cut down on costs, consider refurbished or more budget-friendly manufacturers.
  • Upgradability. If you require upgrades, consider an option that allows for expansions. For this option, desktops are the way to go as they provide expansion slots. Laptops limit the amount of upgrades you can make.

Because there are so many different types of personal computers on the market, picking a PC can seem like a complicated task. However, if you break it down and consider what you need, it's easy to find a PC that fits your lifestyle.

How to set up and maintain your PC

Once you pick a personal computer, you must set it up. Follow these steps to set up and maintain your computer. To set up your PC, you first need to set up the hardware. Then, you can install the operating system and software.

Setting up your personal computer

Take your computer out of its box and connect the components if applicable, including monitor, keyboard, and mouse. Follow the instructions in the box for turning on your computer.

Once finished, follow the on-screen prompts to set up your computer by installing the operating system and updating it to the latest version. This is when you'll create and configure your user account. You'll also establish network settings, connect to the Internet, and set your security and privacy preferences.

Next, install any needed software applications. This includes web browsers, multimedia players, video and audio editors, streaming apps, productivity apps, and antivirus software. Once your PC is set up, you can start using it.

Maintaining your personal computer

Maintaining a PC isn't hard, but it does require some time in order to make sure that your device and files are secure. Make sure to regularly backup your data so you don't lose important files in case of system corruption or your hardware failing. To do this, you can use a cloud service, an external hard drive, a solid state drive, or a paid backup software that regularly backs up your data.

Because you house a lot of personal data on your computer, it's important to install an antivirus software to protect yourself. Additionally, you can also enable firewalls, use a VPN, keep your OS up to date, install all security patches, and follow accepted security practices to protect your privacy and keep your device secure.

To ensure performance remains optimal, make sure to regularly clean up unnecessary files, get rid of unused software, and close out of unnecessary apps and browser tabs.

Personal computer maintenance doesn't end with software, however. You need to make sure you're also cleaning your hardware on a regular basis to remove dusts from fans, vents, and other components. This ensures good airflow to avoid the device overheating.

To keep your devices for their useful life and avoid unnecessary costs, you should also learn common troubleshooting techniques. That way, you can fix problems by yourself whenever they may arise. Look for assistance directly from the manufacturer or from online forums like Reddit if needed.
