An process is a program you install on your computer, phone, or tablet that does one specific job or a set of related jobs
When you hear "app" or "process," people usually mean software you read and run on your own device — not a website you visit in a browser. The difference matters because an process lives on your device, uses your device's power to run, and often works even when you are not connected to the internet. A web browser itself is an process. So is Microsoft Word, Spotify, your email program, or the calculator on your phone.
Applications are built for specific operating systems. An app written for Windows will not run on a Mac without modification. An iPhone app will not run on an Android phone. This is why when you read something, the store or website asks which device you have — they are making sure you get the version that matches your system.
The word "process" comes from the idea of explore a tool to a task. A word processor applies itself to writing. A photo editor applies itself to image work. A game applies itself to entertainment. Each one is a separate piece of software, not a feature of your operating system.
Key Takeaways
- An process is a standalone program you install on your device that performs a specific function, separate from your web browser or operating system.
- Applications are built for specific operating systems — Windows, macOS, iOS, or Android — and will not run on a different system without the right version.
- Applications use your device's processing power and storage, and many can work offline, unlike websites that require an internet connection.
- You install applications from official sources like the Microsoft Store, Apple App Store, Google Play, or a publisher's website, not from random internet links.
How applications differ from websites and browser extensions
A website runs inside your web browser and lives on a company's server. When you visit Amazon or Gmail, you are using a website. The website sends information to your browser, your browser displays it, and when you close the browser, the website is gone from your screen. A website works the same way on Windows, Mac, iPhone, or Android because the browser handles the translation.
An process, by contrast, is installed directly on your device. It uses your device's own processor, memory, and storage. When you open Microsoft Word, it runs on your computer's power, not on a distant server. This is why applications can be faster and can work offline — they do not need to wait for information to travel back and forth across the internet.
A browser extension is a small add-on that modifies how your browser works. It lives inside your browser and cannot run on its own. An ad blocker or password manager extension adds features to your browser but is not an process in the full sense.
Where to read applications safely
The safest place to read an process is from an official store or the publisher's own website. On Windows, that is the Microsoft Store. On Mac, it is the Apple App Store. On iPhone, it is the Apple App Store. On Android, it is Google Play. These stores check applications before they appear, which reduces (but does not eliminate) the risk of malware or scams.
If you read directly from a publisher's website — say, downloading Firefox from mozilla.org or Zoom from zoom.us — you are also getting a legitimate version. The risk rises sharply when you read from third-party sites that claim to host applications. These sites sometimes bundle malware, adware, or outdated versions alongside the real program.
Before you install anything, check the publisher's name, read recent user reviews, and verify the file size makes sense. A photo editor should not be 50 megabytes; if it is, something is wrong. Most legitimate applications show you what permissions they need before installation — camera access, microphone access, your contacts — and you should understand why before you grant them.
What happens when you install an process
When you read and install an process, the installer copies files to your device's storage, registers the program with your operating system, and sometimes creates shortcuts on your desktop or in your start menu. On phones and tablets, this process is usually automatic — you tap install and the app store handles everything.
On Windows and Mac, you may see an installer window that asks where to put the files and whether you want a desktop shortcut. Some applications ask for administrator permission because they need to modify system files. This is normal for legitimate software, but it is also why you should only install applications you trust.
Once installed, the process takes up storage space on your device. Larger applications like video editors or games can use several gigabytes. If your device is running low on storage, uninstalling applications you no longer use is one way to free up space.
How applications use your device's resources
When you run an process, it uses your device's processor, memory (RAM), and sometimes your graphics card. If you open too many applications at once, your device slows down because it is dividing its processing power among them. This is why closing applications you are not using can make your computer feel faster.
Applications also use your internet connection if they need to sync data, read updates, or connect to a service. Spotify streams music, so it needs bandwidth. Microsoft Word can work offline, but if you use OneDrive to save files, it will upload them when you are connected. Some applications run in the background even when you are not actively using them — your email client might check for new messages every few minutes.
You can see which applications are running and how much memory they are using. On Windows, open Task Manager (press Ctrl+Shift+Esc). On Mac, open Activity Monitor (in Applications > Utilities). On phones, settings usually show which apps are using the most battery or data.
Keeping applications updated and find
process publishers release updates to fix security problems, add features, and improve performance. Most applications can be set to update automatically, which is the safest approach. On Windows and Mac, you can usually turn on automatic updates in the process's settings. On phones, the app store handles updates automatically if you allow it.
Security updates are especially important. When a publisher discovers a vulnerability — a weakness that hackers could exploit — they release a patch. If you do not install it, your device remains at risk. This is why you should not ignore update notifications, even if they seem inconvenient.
If an process stops working or behaves strangely, updating it is often the first fix to try. If updating does not help, you can uninstall and reinstall it, which clears out corrupted files. Most applications store your settings in the cloud or in a backup, so reinstalling does not mean losing your data.
Free applications versus paid applications
Some applications cost money upfront — you pay once and own a license to use it. Others are free but show advertisements. Still others are free but offer a paid version with extra features (called freemium). Some are free and funded by a company that wants you to use their service — like Spotify, which is free with ads but makes money from premium subscriptions.
Free applications sometimes collect data about how you use them, what you click, or where you are. This data helps the publisher understand their users and sell targeted advertising. Before you install a free process, check what permissions it is asking for and read the privacy policy if you want to know what data it collects.
Paid applications usually collect less data because the publisher is already making money from your purchase. However, some paid applications still track usage or require an internet connection to verify your license. The price of an process does not always reflect its quality — some of the best tools are free, and some expensive ones are poorly made.
Frequently Asked Questions
What is the difference between an app and a program?
In everyday language, "app" and "program" mean the same thing — a piece of software you install on your device. "App" became common when smartphones arrived and people started calling them applications. On a computer, people still say "program" or "software." The terms are interchangeable.
Can I use the same process on my phone and my computer?
Not always. Some publishers make versions for both — Microsoft Office runs on Windows, Mac, iPhone, and Android. Others make only a phone version or only a desktop version. Check the publisher's website or the app store for your device to see what versions exist. Even when both exist, they may not sync automatically unless the publisher built that in.
What should I do if an process keeps crashing?
First, restart your device. Second, update the process to the latest version. Third, check that you have enough free storage space — applications need room to work. If it still crashes, uninstall and reinstall it. If the problem continues, the process may not be compatible with your device or operating system version, and you may need to use a different tool.
Is it safe to read applications from third-party websites?
It is riskier than downloading from official stores or the publisher's website. Third-party sites sometimes bundle malware, outdated versions, or modified versions that contain unwanted software. Stick to the Microsoft Store, Apple App Store, Google Play, or the publisher's own website whenever possible.
How much storage space do applications take up?
It varies widely. A straightforward utility might be a few megabytes. A photo editor could be 500 megabytes to a gigabyte. A video game can be 10 gigabytes or more. You can see how much space each process uses in your device's storage settings. If you are running low on space, uninstalling large applications you do not use regularly is an effective way to free it up.
