An email says your account will close today unless you click a button. Is it real? You do not have to decide while the message is pressuring you.

Watch: Email says your account will close? Check this first.

What is a phishing email?

Phishing is a trick that tries to get you to give away information, send money, or open something harmful. An email may pretend to be from a company or person you trust.

Warning signs worth checking

• Pressure: “Act now,” a threatened account closure, or a reward that supposedly expires immediately.
• An unexpected request: A bill, attachment, or sign-in demand you were not expecting.
• Private information: A request to reply with a password, payment details, or a verification code.
• An odd sender address: The name says one company, but the actual address looks unrelated or misspelled.

These are clues, not a perfect test. A polished message with your name and a familiar logo can still be fake. A familiar sender’s account can also be misused.

See Microsoft’s phishing guidance for more warning signs.

A made-up example

This fictional example shows the pattern: an unexpected problem, a deadline, and a request to act through the message.

Check the claim without using the message

1. Stop before clicking, replying, scanning a QR code, or calling its number.
2. Open the service through a known app, saved bookmark, or address you know is correct.
3. Look for the claimed problem in your account, or contact the company through a trusted number.
4. If the message appears to come from a friend, confirm through a separate conversation using their usual contact details.

If you do not know the correct address, ask someone you trust to help verify it. The top search result alone is not proof of authenticity.

A verification code belongs in a verified sign-in process you started. Do not read it to someone who contacts you or approve an unexpected sign-in request.

Report it

Use your email service’s Report phishing option when available. In Gmail on a computer, open the message’s More menu beside Reply and choose Report phishing. Avoid its links and attachments while doing this. Menu wording varies by app.

Do not bypass a warning just because the message looks important. For Gmail instructions, see Google’s phishing guide.

What if I already responded?

Stop interacting and take the next step that matches what happened:

• Entered a password: Go directly to the real service, change it, and change it on other accounts where you reused it. Review account security and turn on additional sign-in protection.
• Shared card or bank details, or sent money: Contact the provider promptly using its official contact information.
• Downloaded or opened something suspicious: Update your security software and run a scan. Ask a trusted support provider if you need help.

For U.S. reporting and recovery guidance, use ReportFraud.ftc.gov and IdentityTheft.gov. The FTC’s phishing guide explains these steps.

If someone got into your email: Follow our 10-step hacked-email recovery checklist, including how to check for hidden inbox rules and forwarding.

A website says “Download,” but what happens when you choose it?

A simple example

You receive an email with a photo attached. Choosing Download can save a copy on your device. You can then open that copy with a photo app.

For an ordinary photo or document, downloading a copy usually leaves the original with the service.

Where did the download go?

Need to find a saved file now? Follow our missing downloads, photos, and documents checklist to check likely locations before downloading another copy.

Browsers often save files in a folder called Downloads, unless you choose another location or change the settings.

The browser’s downloads list may offer “Show in folder” or a similar option. On Windows, look in File Explorer. On a Mac, look in Finder.

Phone apps may save items to a Files app, a photo library, or their own storage. If you cannot find an item, check the app’s download instructions.

Download, open, and install

• Download: Bring the item to your device.
• Open: View it or use it with an app.
• Install: Set up software so the device can run it.

Downloading an app installer does not always install the app. It may need another step. A document or picture usually does not need an installation step.

Download or stream?

Streaming plays online music or video as it arrives. It normally needs a continuing connection. A download can let you use a saved item later.

Some services allow offline downloads only inside their app. Those copies may expire or depend on your account. They are not always ordinary files you can move elsewhere.

Before you click Download

• Make sure you recognize the source.
• Look for the file you intended, rather than a large advertisement marked Download.
• Get app installers from the official store or software maker.
• Do not bypass a browser or device warning just to finish the download.

Any downloaded file can carry risk. A familiar-looking filename alone does not prove it is safe.

Still can’t find the file? Open your browser’s Downloads list (often Ctrl + J on Windows, or Command + Option + L in Safari on Mac), then select the downloaded item or choose Show in folder if available. Do not run an unfamiliar installer just to check what it is.

If the download does not finish

Check your connection, available storage, and the browser’s download status. Wait until it says the download is complete before expecting to open the full file.

Repeatedly choosing Download can create several copies. Check whether the item already arrived before trying again.

Next, read What Are Files and Folders? to learn how to find and organize what you saved.

Computer basics, in plain English · Updated October 1, 2026

Your computer offers several power choices. Here is what the main ones mean.

Sleep: taking a short break

Sleep uses less power and usually keeps your session ready to return to. Waking it often brings you back to the apps you were using.

The details vary by device and settings. Sleep is not a substitute for saving: a flat battery or power problem can still interrupt your work.

Shut down: finishing for now

Shut down closes the session and turns the computer off. Use the on-screen command so the system can finish properly.

On Windows, choose Start → Power → Shut down. On a Mac, choose Apple menu → Shut Down. Save first and let it finish.

Restart: a fresh start for the system

Restart closes the system and starts it again. It can help after a software problem or when an update asks for it.

On Windows, choose Start → Power → Restart. On a Mac, choose Apple menu → Restart.

If instructions say Restart, use that choice. Turning off the monitor or closing a laptop lid is not the same action.

Which should I choose?

• A short break: Sleep is usually convenient.
• Finished using it: Shut down is an option when you no longer need it running.
• An app or device is acting strangely: Save, then try Restart.
• An update requests a restart: Follow its instructions and allow time to finish.

What about the monitor’s power button?

On a setup with a separate monitor, that button usually controls the screen only. The computer may still be running.

A laptop or all-in-one combines parts in one housing. Learn more in What Is a Computer?

Before you step away

Save your work and lock your screen if others could access it. Locking protects your session; it does not necessarily put the computer to sleep.

If a long upload or other task needs to continue, check its requirements and your device’s sleep settings. Do not assume closing the lid will keep it running.

Avoid pulling the power plug or holding the power button as your normal way to turn off a computer. Forced power-off can lose unsaved work.

Windows references: Microsoft’s power-options guide and restart instructions. Mac reference: Apple’s shut down and restart guide.

Why does restarting help? Read our simple explanation: Why turning it off and on again actually works.

Computer basics, in plain English · Updated October 1, 2026

Someone says your photos are “in the cloud.” They are talking about computers, rather than something floating in the sky.

An everyday example

You take a picture on your phone. A photo service may upload a copy to its servers. Later, you sign into that service on your computer and see the picture there too.

Depending on your settings, the phone may keep a full copy, a smaller preview, or download the original when you need it.

What is an upload?

Upload means sending something from your device to an online service. Download means bringing something from that service to your device.

Think of uploading a photo as putting it in an online storage space, and downloading as bringing a copy back.

What is syncing?

Syncing keeps connected copies up to date. Change a synced document on one device, and the change may appear on your other devices.

That includes deletions. Removing a synced photo on your phone may remove it from the service and other connected devices too.

Is the cloud a backup?

Some services provide backup features, but cloud storage and syncing alone do not guarantee you can recover everything.

Check whether your service keeps deleted files or older versions, and for how long. Important files should have another recoverable copy. Test that you can actually open or restore that copy.

Do I need the internet?

You normally need a connection to upload new files or fetch files that are only online. Some apps let you mark files for offline use.

Seeing a filename or thumbnail does not always mean the full file is on your device. Open what you need while connected, and check the service’s offline settings before traveling.

What should I check?

• The account: Know which sign-in holds your files.
• The status: Check that uploads have finished.
• The space: Services often have storage limits.
• The sharing: Check who can view a shared file or link.
• The recovery: Know how to recover deleted items.

Before deleting photos to free space, find out whether Delete removes them everywhere. Use your service’s documented free-space feature if that is what you intend.

You have a photo you want to send to someone. Email can carry that picture along with your message.

Before you begin

Find the photo and check that it is the right one. If you need help finding a saved picture, start with our files and folders guide.

You also need the person’s email address. A small typing mistake can send your picture to the wrong place.

The basic steps

1. Start a message. Open your email app or website and choose Compose, New message, or a similar option.
2. Add the recipient. Enter their address in the To field. Check any suggested contact before selecting it.
3. Add a subject and message. For example, “Photo from our picnic.”
4. Choose Attach. Look for a paperclip, an Attach button, or a photo option.
5. Choose your photo. Find it in the file or photo picker and confirm your choice.
6. Wait for it to attach. Look for a filename, thumbnail, or completed upload.
7. Check, then send. Confirm the recipient and the picture before pressing Send.

The labels vary between email apps. On a phone, the app may ask for access to photos. If it offers selected-photo access, you can choose only the pictures you want to share.

A Gmail example on a computer

In Gmail, start a message with Compose. Select the Attach files paperclip, choose the saved photo, and select Open. Wait for the attachment to finish before sending.

For current Gmail instructions, see Google’s attachment guide.

Sending several photos or a large picture

Start with one photo and check that it arrives. For a group of pictures, compare the total file size with your email service’s limit. If the message will not send, use a sharing link rather than repeatedly attaching the same files.

Follow our guide to sharing a file link with the right permissions. Ask the recipient to confirm they can open it before deleting or moving anything.

Attachment or sharing link?

An attachment sends a copy with the message. A sharing link points to a file held by an online service.

Large photos or groups of photos may exceed your email service’s attachment limit. The service might suggest a link instead. If you use one, check who can open it; sending a link does not always give the recipient permission.

A quick check before Send

• Is the address correct?
• Did I choose the right photo?
• Does the photo show anything private I do not want to share?
• Has the upload finished?

Start by sending one ordinary photo to your own email address. Open the received message and see what the attachment looks like.

If someone asks for a clearer copy, use the app’s original-size option if available and within the service’s size limit.

Computer basics, in plain English · Updated October 1, 2026

People say “use the app” for everything from checking the weather to writing a letter. What do they mean?

Think of an app as a tool

• A calculator app helps you work with numbers.
• A camera app lets you take pictures.
• A writing app helps you make documents.
• A browser app lets you visit websites.

Your device can have many apps, just as a kitchen has different tools for different jobs.

How do I open one?

Look for its name or picture, called an icon. On a phone or tablet, you usually tap it. On a computer, you can choose it from the app menu, search for its name, or open its desktop icon.

Some desktop icons need a double-click. Items in menus usually need one click.

How do I close one?

Save your work first. Computer apps usually have a close button on the window. A Mac app can stay running after its window closes; its menu’s Quit option closes the app.

On a phone, going back to the home screen leaves the app’s screen. The phone manages what can keep running in the background. You generally do not need to force-close every app after using it.

An app, a file, and an account

These do different jobs:

• App: The tool, such as a photo viewer.
• File: The saved item, such as your dog’s photo.
• Account: Your sign-in with a service, often connected to an email address.

Installing an email app does not automatically create an email account. Removing an app does not necessarily delete your account with its service.

Where do apps come from?

Some arrive with your device. Others come from its official app store or the software maker’s official website. Check the app’s name, maker, and any cost before installing.

If an app asks to use your camera or location, consider whether that fits what you are doing. A video call needs a camera; a simple calculator usually does not.

Try it yourself

Open your device’s calculator. Work out 2 + 2, then leave or close it. You have used an app to do a task.

Next, learn what files and folders are.

Computer basics, in plain English · Updated November 3, 2026

Copy and paste lets you use the same words in another place without typing them again. You might copy an address into a message or a recipe into a note.

Copy and paste keyboard shortcuts at a glance

Looking for the keys? Hold Ctrl on a Windows computer or Command (⌘) on a Mac, then press the letter shown. These shortcuts work in many programs, including documents, email, and browser text boxes.

• Copy: Ctrl + C (Windows) or Command + C (Mac).
• Paste: Ctrl + V (Windows) or Command + V (Mac).
• Cut: Ctrl + X (Windows) or Command + X (Mac).
• Select all: Ctrl + A (Windows) or Command + A (Mac).
• Undo: Ctrl + Z (Windows) or Command + Z (Mac).

Example: To copy a sentence, highlight it, hold Ctrl and tap C. Click where you want the copy, hold Ctrl and tap V. The original stays where it was.

1. Select the words you want to copy

To copy a sentence with a mouse, put the pointer at its beginning. Hold the main mouse button, move to the end of the sentence, then release. The selected words usually have a colored background.

This is called selecting or highlighting. Only the selected words will be copied.

2. Copy with a mouse or keyboard

Right-click the selected words and choose Copy if the menu offers it. You can also use these keyboard shortcuts:

The plus sign means “hold the first key, press the second key, then release.” Do not type a plus sign. For example, hold Ctrl, tap C once, then release Ctrl.

No right-click on your Mac? Hold the Control key while clicking the selected words, then choose Copy. Control-click opens the menu; Command + C is the Mac copy shortcut.

Copying often gives no visible confirmation. The selected words stay where they are. Continue to the next step.

3. Choose where the words should go

Open your note, document, or message. Click in a place where you can type. A blinking line often shows where the words will appear.

If other words are selected there, pasting may replace them. Click an empty place if you want to add text.

4. Paste the copied words

Right-click the typing area and choose Paste, or use the Paste shortcut above. You should now see the copied words.

Copying uses a temporary holding place called the clipboard. Copying something else usually replaces its current contents. The clipboard is not a reliable place to save work.

Try it yourself: a copy-and-paste exercise

1. Open a new, unimportant note or document.
2. Type “Milk and bread.”
3. Select those words and copy them.
4. Click on a new line and paste.

You should see the words twice. You have kept the original and made a copy.

Copy and paste not working? Check these first

1. Make sure the text is selected. Look for a colored highlight over the words before choosing Copy. If nothing is highlighted, select the words and copy again.
2. Click somewhere you can type. Try a blank note or document. You cannot paste text into ordinary text on a web page. Look for a blinking typing cursor in a text box, document, or message.
3. Use the right shortcut. Windows uses Ctrl + C and Ctrl + V. Mac uses Command + C and Command + V. If the shortcut fails, try the app’s Edit menu or its right-click menu.
4. Copy the text again if the wrong words appear. Copying another item usually replaces the clipboard’s current contents. Go back to the original words, select them, copy, then paste without copying anything else in between.
5. Check whether the source is an image or the app restricts copying. A photo or screenshot of words is different from selectable text. Some devices have a text-recognition feature, but the normal selection steps may not work on a picture. Some apps also limit copying or pasting.

If it works in a plain note but not in another app, focus on that app or typing area. If a paste accidentally replaces words, use the app’s Undo command before making more changes.

Need to show someone what you are seeing? Follow our simple screenshot guide for Windows and phones.

How to copy and paste on an Android phone or iPhone

Touch and hold a word until selection handles appear. Drag the handles to cover the words you want, then tap Copy. Open the message, note, or other place where you want the words, touch and hold the typing area, and tap Paste. Some apps use slightly different menus.

To copy a link, touch and hold the link and look for Copy link. You can also copy an address from the browser address bar.

Can I copy a website address?

Yes. Click the address bar at the top of your web browser. Select the full address, copy it, then click in a message or note and paste it. These steps copy the address; they do not copy the entire website.

Can I copy and paste files the same way?

You can also copy files, but you select a file and paste into a folder rather than selecting words and pasting into a typing area. Start with the text exercise above, then read What Are Files and Folders? to understand where files go.

How to paste without the original formatting

If text arrives with unexpected fonts or colors, use your app’s Paste as plain text or Paste and Match Style option. Many Windows browsers and apps support Ctrl + Shift + V; on Mac, the shortcut varies by app. You can also look in the Edit menu for a plain-text paste option.

Copy and cut are different

Cut prepares selected text to be moved and can remove it from the original place. Start with Copy while practicing. These steps cover text; moving files has its own rules.

Computer basics, in plain English · Updated October 1, 2026

You saved a document, but where did it go? Understanding files and folders makes that question easier to answer.

What counts as a file?

A photo of your dog, a shopping list, a song, and a saved receipt can all be files. Each file has a name so you can tell it apart from other items.

An app is the tool you use to work with a file. A writing app opens a document; a photo app opens a picture. The tool and the item are different things.

What does a folder do?

A folder groups items together. You might have a folder called “Family Photos” and another called “Receipts.” A folder can also hold other folders.

The names are your labels. They do not have to be fancy. “Dentist appointment October” is easier to recognize later than “Document 7.”

What is the difference between a file and a folder?

A file contains information, like one photograph, spreadsheet, or PDF. A folder organizes files and can contain other folders. For example, Documents → Taxes → receipt.pdf means the file receipt.pdf is inside the Taxes folder, which is inside Documents.

How to create a folder

1. Windows: open File Explorer, go to Documents, right-click an empty space, choose New → Folder, type a name, and press Enter.
2. Mac: open Finder, go to Documents, then choose File → New Folder. Name it and press Return.

Give folders clear names such as “Family Photos” or “2026 Receipts.” You can move a file into a folder by dragging it there, but start with a practice file until you are comfortable.

Save, open, and download

• Save: Keep your work in a file. Some apps save automatically; others need you to choose Save.
• Open: View or work with a file you already have.
• Download: Bring a copy of a file from an online service to your device.

When you save something, notice both its name and its location. If the app offers Save As, it usually lets you choose a name or location for a copy.

Where should I look for my files?

On Windows, File Explorer helps you find files and folders. On a Mac, Finder does that job.

Common places include:

• Downloads: Often where files downloaded through a browser go, unless you chose another location.
• Documents: A common place for letters and other written work.
• Pictures: A common place for images.
• Desktop: The area behind your open windows can also show saved items and shortcuts.

These are starting places, not rules. A file can be saved somewhere else, and some apps keep work in their own library or online account.

Can’t find something you saved? Follow our step-by-step guide to finding missing downloads, photos, and documents.

What are the letters after the dot?

A filename may end with letters such as .jpg, .pdf, or .docx. This ending is called a file extension. It helps identify the kind of file.

You do not need to memorize these. Changing “photo.jpg” to “photo.pdf” does not turn a picture into a PDF. Use an app’s export or conversion option when you need a different format.

Copy, move, and delete

• Copy: Make another copy and keep the original.
• Move: Put the item in a different location.
• Delete: Remove the item. It may go to Recycle Bin or Trash, but some deletions are immediate.

Before deleting something important, make sure you have a recoverable copy. If a folder is connected to a cloud service, deleting an item may also remove it from other devices.

Keeping a file in two folders on the same computer can help organization, but it does not protect it if the computer’s storage fails.

Computer basics, in plain English · Updated October 1, 2026

You want to visit a website, but someone says “open your browser.” What are you supposed to open? Here is the simple explanation.

Browser, search engine, and website: three different things

These names often get mixed together. Each has a different job:

• Browser: The app you open to visit websites. Think of it as your way of traveling.
• Search engine: A service that helps you find pages, such as Google Search or Bing. Think of it as a directory.
• Website: The place you visit, such as NoPanicTech. Think of it as your destination.

An example: You open Chrome, search Google for “printer offline,” and choose a NoPanicTech article. Chrome is the browser, Google is the search service, and NoPanicTech is the website.

When someone says “open Google,” they might mean Chrome or the Google Search website. It is fine to ask which one they mean.

The address bar: where to go

Near the top of the browser is a long box called the address bar. It shows the address of the page you are viewing.

You can use it in two ways:

1. Go to a known website: Click or tap the bar, replace its contents with nopanictech.com, and press Enter or Go.
2. Search for a topic: Type words such as “what is a computer” and press Enter or Go. The browser normally sends those words to its chosen search engine.

A website address tells the browser where to go. A search asks for possible places to visit.

Links: how you move between pages

A link is something you can click or tap to open another page. Links may look like underlined words, a button, or a picture.

Web links usually need one click. You do not need to double-click them. The browser’s Back arrow usually takes you to the page you just left.

Tabs: several pages in one browser

A tab holds an open page. You can have one tab for a recipe and another for your email. Selecting a tab switches the page you are looking at.

Closing a tab closes that page. It does not delete the website or your account. Save anything you are writing before closing it; an unfinished form or message may be lost.

Bookmarks: a shortcut for later

A bookmark saves a page’s address so you can find it again. Many browsers use a star or a bookmark menu to save one.

A bookmark remembers where a page is. It usually does not save a complete offline copy of the page.

Do I need the internet?

You can open the browser app without being online, but loading most websites needs an internet connection. If the browser opens and pages will not load, the connection or the website may be having trouble.

For an important account, use an address you already know or a bookmark you saved from the correct site. A sponsored search result is not proof that a page belongs to the company you want.

Computer basics, in plain English · Updated October 1, 2026

You do not need to know technical words to start using a computer. Let’s begin with the parts you can see and what each one does.

The four parts of a typical desktop setup

1. The computer: the part doing the work

A desktop computer can be a tall box, a small box on the desk, or a little box mounted behind the screen. People often call a tall one a tower.

Inside are the parts that run your programs and hold your saved files. A program, also called an app, is a tool you use on the computer—for example, a tool for writing a letter.

2. The monitor: the screen you look at

A separate monitor displays what the computer sends to it. Think of it as a window into what is happening.

Turning off a separate monitor usually turns off the screen only. The computer may still be running. When you want to shut down the computer, use its on-screen Shut down option.

There is an exception: an all-in-one computer has its computer parts built into the screen’s housing. We’ll explain that below.

3. The mouse: point, click, and scroll

Move the mouse across the desk and a small arrow usually moves across the screen. That arrow is called the pointer.

• Click: Point at something and press the main mouse button once. This can select an item or press an on-screen button.
• Double-click: Press the main button twice quickly. Many desktop items, such as folders, open this way.
• Scroll: Roll the wheel to move up or down a page.
• Right-click: Press the other button to see extra choices for an item.

Most mice use the left button as the main button, but you can change that in settings. Web links usually need just one click.

4. The keyboard: type words and numbers

Click in the place where you want to write, then use the keyboard.

• Space bar: Adds a space between words.
• Backspace: Usually removes the character just before the typing position. On a Mac, this key is often labeled Delete.
• Enter or Return: Can start a new line, confirm a choice, or submit something. What it does depends on the app.
• Shift: Hold it while pressing a letter to type a capital letter.

You do not need to memorize every key. Start with the ones you use.

How the parts work together

Imagine writing a shopping list:

1. You use the mouse to open a writing app.
2. You use the keyboard to type “milk.”
3. The computer handles your typing and runs the app.
4. The monitor shows the word “milk.”

When you save the list, the computer stores it in the place you choose. Some apps also save files through an online service.

What about laptops and all-in-one computers?

A laptop puts the computer, screen, and keyboard into one device you can fold and carry. The flat touchpad below the keyboard does the mouse’s job: move a finger on it to move the pointer. You can also connect a separate mouse.

An all-in-one looks like a monitor, but the computer is built into the same housing. It usually uses a separate keyboard and mouse. The screen and computer share one unit.

Do I need the internet to use a computer?

Not for everything. Many computers can let you write or view files saved on them without an internet connection. Visiting websites and using most online services needs a connection.

A good first step: Look at your own setup and find the screen, keyboard, and mouse or touchpad. Then see whether the computer is a separate box or built into the device. You have already learned the main parts.
