Internet & Technology Vocabulary in English

Internet and technology vocabulary is some of the most practical English you can learn today. Whether you are sending an email, browsing social media, downloading a file, or setting up a new device, you will encounter these words every single day.

Frequently Asked Questions
What is the difference between download and upload?
Download means copying data from the internet or a remote server to your own device — for example, saving a file or installing an app. Upload means sending data from your device to the internet or a server — for example, posting a photo on Instagram or submitting a document to a website. Think of it as the direction of movement: download comes to you, upload goes away from you.
What is the difference between a website and an app?
A website is accessed through a web browser and works on any device with internet access. An app (application) is a piece of software you download and install on a specific device, typically a smartphone or tablet. Many services offer both — for example, Facebook has a website and a mobile app. Apps often work faster and offer more features than mobile websites.
What does it mean to stream content?
Streaming means watching or listening to media — such as a film, TV show, or song — in real time over the internet without downloading the file to your device first. Services like Netflix, Spotify, and YouTube all use streaming technology. You need a stable internet connection to stream smoothly, which is why bandwidth is important.
Why do English learners need internet vocabulary?
Internet vocabulary is essential for everyday life in English-speaking countries and for online study. You will need these words to understand instructions on apps and websites, follow online courses, read tech news, and communicate in digital workplaces. Many of these terms also appear in IELTS and Cambridge English exam reading and listening tasks.
What is the difference between a username and a password?
A username is the name or handle that identifies you publicly on a platform — it may be visible to other users. A password is a secret combination of characters that only you should know, used to prove that you are the account owner. Both are required when you log in, but the username identifies who you are while the password verifies that it really is you.
What does navigate mean in a technology context?
In a technology context, navigate means to move around a website, app, or computer system using clicks, taps, menus, or links. For example: The new website design makes it much easier to navigate. The word comes from sailing (to steer a ship), but it is now widely used for moving through digital environments.
What is the difference between social media and a search engine?
A search engine (like Google) helps you find information and websites by typing keywords. Social media (like Instagram or Twitter) is a platform for sharing content, connecting with people, and following communities. While some social platforms include search functions, their primary purpose is communication and content sharing rather than information retrieval.
What does bandwidth mean in everyday English?
Technically, bandwidth refers to the volume of data that can be sent over an internet connection per second — measured in megabits per second (Mbps). In everyday speech, people use bandwidth informally to mean time or mental capacity: I don't have the bandwidth to take on more work right now. Both meanings are worth knowing at B1 level.
How do hashtags work on social media?
A hashtag is a word or short phrase preceded by the # symbol, used to tag and categorise posts on platforms like Twitter, Instagram, and TikTok. When you click a hashtag, you see all public posts that use the same tag. Hashtags help content reach people who are interested in a topic, even if they do not follow you.
