Technology becomes less intimidating when you understand the words people use to describe it.
Terms such as Wi-Fi, Bluetooth, cloud storage, streaming, apps, updates, and two-factor authentication appear everywhere.
The problem is that instructions often use these words without explaining what they mean.
A senior might hear, “Connect the device to Wi-Fi, open the app, pair it through Bluetooth, and save the file to the cloud.”
That sentence sounds simple to someone who already understands the terms. To a beginner, it might sound like a foreign language with a monthly subscription.
This guide explains 25 common technology terms in plain English. Each definition includes a simple example and a practical reason the term matters.
Quick Learning Tips
- Learn a few terms at a time.
- Practice each term on a real device.
- Write unfamiliar words in a notebook.
- Ask someone to explain the term using an example.
- Do not pretend you understand when you do not.
- Ask for instructions without technical language.
- Return to this glossary whenever a word feels confusing.
1. App
An app is a program that performs a specific task on a phone, tablet, computer, smart television, or other device.
The word “app” is short for application.
Examples
- Phone app for making calls
- Messages app for sending texts
- Camera app for taking pictures
- Banking app for managing an account
- Weather app for checking forecasts
- Video-calling app for speaking with family
Simple Definition:
An app is a tool inside your device.

2. Browser
A browser is the program used to visit websites.
Common browsers include Chrome, Safari, Edge, and Firefox.
A browser lets you type a website address, search the internet, open links, read articles, watch videos, and use online services.
Simple Definition:
A browser is the door you use to enter the internet.
3. Wi-Fi
Wi-Fi connects devices to the internet without using a cable.
A home router sends the wireless signal. Phones, tablets, computers, televisions, cameras, and smart devices connect to that signal.
Wi-Fi usually requires
- Internet service
- A modem or router
- A network name
- A Wi-Fi password
Safety Tip:
Public Wi-Fi at stores, hotels, airports, and restaurants is less private than your protected home network.
4. Bluetooth
Bluetooth connects nearby devices without a cable.
It usually works across a short distance.
Common Bluetooth connections
- Phone to hearing aids
- Phone to wireless headphones
- Phone to a car
- Tablet to a keyboard
- Health monitor to a mobile app
- Phone to a smart speaker
Simple Definition:
Bluetooth lets nearby devices talk to each other.
5. Internet
The internet is the worldwide network that connects computers, phones, websites, apps, services, and people.
It supports email, video calls, websites, online banking, shopping, streaming, social media, maps, and many smart-home devices.
Wi-Fi is one method used to connect a device to the internet. Wi-Fi and the internet are related, but they are not the same thing.
6. Mobile Data
Mobile data connects a phone or cellular tablet to the internet through a mobile carrier.
It works when Wi-Fi is unavailable, provided the device has cellular coverage and an active plan.
Activities that use mobile data
- Browsing websites
- Watching videos
- Using maps
- Video calling
- Downloading files
- Using social media
Cost Tip:
Video and large downloads use more mobile data than simple text messages or email.
7. Cloud Storage
Cloud storage saves files on computers operated by an online service instead of keeping everything only on your device.
Photos, contacts, documents, and backups might be stored in the cloud.
Examples
- Google Drive
- Apple iCloud
- Microsoft OneDrive
- Dropbox
Simple Definition:
Cloud storage saves information online so it can be reached from another approved device.
8. Download
Download means moving a file, app, picture, document, or other information from the internet onto your device.
Examples
- Installing an app
- Saving a photograph
- Saving a PDF document
- Downloading a software update
- Saving an email attachment
Safety Warning:
Do not download files or apps from unexpected messages or unfamiliar websites.
9. Upload
Upload means sending a file from your device to a website, app, online service, or another person.
Examples
- Posting a photograph on Facebook
- Adding a document to cloud storage
- Sending an image through a website form
- Adding a video to YouTube
- Submitting a file to an online account
Memory Trick:
Download brings something down to your device. Upload sends something up to the internet.
10. Streaming
Streaming means watching or listening to content through the internet without permanently saving the complete file first.
Examples
- Watching YouTube
- Watching a movie service
- Listening to internet radio
- Playing a podcast
- Watching a live event online
Streaming requires a steady internet connection and might use a large amount of mobile data.

11. Online Account
An online account stores your information and settings for a website, app, store, bank, email service, or other digital service.
An account usually requires a username or email address and a password.
Safety Tip:
Create accounts only through official websites and apps.
12. Username
A username identifies you when signing into an online account.
Some services use an email address as the username. Others let you create a separate name.
A username is different from a password. The username identifies the account. The password protects it.
13. Password
A password is a secret combination of letters, numbers, and symbols used to protect an account or device.
Strong password rules
- Use a different password for every important account.
- Make passwords long.
- Avoid names, birthdays, and simple number patterns.
- Do not send passwords through text messages.
- Do not share passwords with unexpected callers.
- Store passwords securely.
Do Not Reuse:
One stolen password should not give a criminal access to every account you own.
14. Two-Factor Authentication
Two-factor authentication adds a second security step after entering a password.
The second step might use:
- A code sent to your phone
- An authentication app
- A fingerprint
- Face recognition
- A security key
This protects the account when someone steals or guesses the password.
Simple Definition:
Two-factor authentication means proving your identity in two different ways.
15. Verification Code
A verification code is a temporary number used to confirm your identity.
It might arrive through a text message, email, phone call, or authentication app.
Never Share It:
Anyone asking you to read a verification code over the phone might be trying to enter your account.
16. Software Update
A software update installs improvements, security repairs, new features, and error fixes.
Phones, tablets, computers, apps, televisions, routers, and smart devices receive updates.
Before a major update
- Connect the device to power.
- Use trusted Wi-Fi.
- Back up important information.
- Allow enough time.
- Use the device settings or official app store.
17. Notification
A notification is a message or alert from an app, device, website, or service.
Notifications might announce:
- New text messages
- Missed calls
- Appointment reminders
- Package deliveries
- Weather warnings
- Security alerts
- Software updates
Too many notifications create confusion. Turn off alerts from apps that do not matter.
18. Link
A link is clickable text, a button, or an image that opens another webpage, app, file, or location.
Links appear in websites, emails, text messages, social media posts, and online advertisements.
Safety Warning:
Do not open unexpected links from strangers or alarming messages.
19. Spam
Spam is unwanted communication sent through email, text messages, phone calls, social media, or online comments.
Some spam is advertising. Some contains scams, harmful links, or fake offers.
What to do
- Do not reply to suspicious messages.
- Block the sender.
- Use the report-spam or report-junk feature.
- Do not open attachments.
- Do not click unknown links.

Phishing is an attempt to steal private information by pretending to represent a trusted company, person, or organization.
A phishing message might pretend to come from:
- A bank
- A delivery company
- A government agency
- A technology company
- A family member
- A streaming service
The message often asks you to click a link, sign in, confirm payment, or send a code.
Memory Trick:
Phishing means someone is fishing for your information.
21. Scam
A scam is a dishonest plan used to steal money, information, account access, or property.
Common scams targeting seniors
- Fake bank alerts
- Family emergency scams
- Government impersonation

- Who sees social media posts
- Who can call or message you

GPS helps with:

25. Artificial Intelligence
Artificial intelligence, often called AI, is technology that performs tasks associated with human thinking.
