English Technology Vocabulary: 80 Essential Words for Daily Life

English technology vocabulary is the everyday language you need to use phones, computers, websites, social media, and workplace tools in English. Start with practical words such as app /æp/, password /ˈpæs.wɝːd/, download /ˈdaʊn.loʊd/, browser /ˈbraʊ.zɚ/, and update /ʌpˈdeɪt/, then learn them through real actions rather than isolated lists.

Technology English matters because it appears far beyond a computer class. You see it when a colleague shares a link, a friend sends a voice message, a hotel asks for an email address, or a show character says their phone battery is dead. For more everyday core language, pair this list with the 100 most common English words.

The International Telecommunication Union reported that 5.5 billion people were online in 2024, roughly 68% of the global population. That scale helps explain why technology vocabulary travels quickly across borders, even when the rest of a conversation happens in another language.

Devices and basic hardware

A device /dɪˈvaɪs/ is any piece of electronic equipment, including a smartphone /ˈsmɑːrt.foʊn/, laptop /ˈlæp.tɑːp/, tablet /ˈtæb.lət/, or smart watch. In everyday speech, people often say my device when they do not need to name the exact object.

A screen /skriːn/ is the display, while a keyboard /ˈkiː.bɔːrd/ and mouse /maʊs/ are input tools. A mouse is called a mouse because early models had a cable resembling a tail, a useful bit of vocabulary history that makes the unusual name easier to remember.

Use charger /ˈtʃɑːr.dʒɚ/ for the cable, plug, or charging unit that gives a device power. Battery /ˈbæt̬.ɚ.i/ can refer to the power source itself or its remaining charge: “My battery is at ten percent.”

Internet and connection vocabulary

The internet /ˈɪn.t̬ɚ.net/ is the global network that connects computers and services. Wi-Fi /ˈwaɪ.faɪ/ is the wireless connection that lets your device join a local network, usually through a router.

This distinction is practical. If someone says “The Wi-Fi is down,” they mean the wireless connection is unavailable. If Wi-Fi works but a website will not load, the problem may be the internet provider, a server, or the website itself.

Browser

A browser /ˈbraʊ.zɚ/ is an application for opening websites. Common browser actions include opening a tab /tæb/, entering a web address, following a link /lɪŋk/, and using a search engine /sɝːtʃ ˈen.dʒɪn/.

A website /ˈweb.saɪt/ contains one or more web pages /ˈweb peɪ.dʒɪz/. In casual English, people may say “Send me the website,” even if they technically mean one specific page or link.

Cloud

The cloud /klaʊd/ is not a physical object floating above you. It is a general name for services that store data or run software on remote computers connected through the internet.

When you save photos “to the cloud,” the files are stored on servers operated by a service provider. A server /ˈsɝː.vɚ/ can provide web pages, files, games, email, or streaming video to many users at once.

Naomi S. Baron examines how digital tools change everyday communication in How We Say Now. Her work is a useful reminder that terms such as message /ˈmes.ɪdʒ/, call /kɑːl/, and reply /rɪˈplaɪ/ now refer to several different digital actions, not just one traditional medium.

Apps, files, and everyday actions

An app /æp/ is short for application /ˌæp.ləˈkeɪ.ʃən/. Apps can be for banking, maps, games, social media, music, work, or nearly any other task.

A file /faɪl/ is a saved unit of information, such as a photo, document, spreadsheet, video, or audio recording. A folder /ˈfoʊl.dɚ/ organizes files, like a digital version of a paper folder in an office.

Download and upload

Download /ˈdaʊn.loʊd/ means receiving a file from the internet onto your device. You might download a PDF, a game, an attachment, or an offline episode before a flight.

Upload /ʌpˈloʊd/ means sending a file from your device to an online service. You upload a profile photo, a résumé, or a video. These verbs are opposites, so remember the direction: download comes down to you, upload goes up to a service.

Update

An update /ʌpˈdeɪt/ can be a noun or a verb. As a noun, it is a newer version of software. As a verb, it means installing that version or changing information: “Update the app” and “Update your address.”

Many people postpone updates because they take time, but updates can fix bugs and security weaknesses. A bug /bʌɡ/ is an error in software that makes it behave incorrectly. In technology English, “There is a bug” is neutral and does not blame a person.

Screenshot

A screenshot /ˈskriːn.ʃɑːt/ is an image of what is currently visible on a screen. It is one of the most useful modern communication words because it can show an error, a reservation, directions, a message, or proof of payment without requiring a long explanation.

In films and series, text messages, browser searches, video calls, and notifications often carry important plot information. Use movies to learn English actively: pause a short scene, identify the technology action, then repeat the full sentence aloud.

Communication and social media words

A notification /ˌnoʊ.t̬ə.fəˈkeɪ.ʃən/ is an alert from an app or website. It may appear as a sound, vibration, badge number, or message on your lock screen.

A feed /fiːd/ is the stream of posts you see on a social media platform. To scroll /skroʊl/ is to move through that feed, usually by swiping upward on a phone screen.

A post /poʊst/ can be a noun or verb. You can create a post, post a photo, repost something, or comment beneath another person’s post. The word has older meanings related to mail and public notices, but its social media meaning is now ordinary everyday English.

Gretchen McCulloch, in Because Internet, analyzes how online writing develops its own conventions. Her work helps explain why a short reply, repeated letters, punctuation, emojis, and lowercase writing can all signal tone, not merely grammar.

Culturally, technology vocabulary can reveal age, workplace habits, and region. A younger speaker may say “DM me” /ˌdiːˈem miː/ for a private message, while a workplace may prefer “Send me a message on Teams” or “Email me.” Learn the platform-neutral verbs first: send, share, call, reply, attach, and save.

Privacy, security, and troubleshooting

A password /ˈpæs.wɝːd/ protects an account. A username /ˈjuː.zɚ.neɪm/ identifies the account holder, while a password verifies that the person logging in should have access.

Log in /lɔːɡ ɪn/ means entering an account, and log out /lɔːɡ aʊt/ means leaving it. You may also hear sign in /saɪn ɪn/ and sign out /saɪn aʊt/, which normally mean the same thing.

A scam /skæm/ is a dishonest attempt to get money, data, or access. A suspicious message may be phishing /ˈfɪʃ.ɪŋ/, a scam that pretends to come from a trusted company and tries to steal passwords or financial information.

For basic troubleshooting, learn these sentences:

• “The app keeps crashing.” A crash /kræʃ/ happens when software suddenly closes or stops working.
• “My screen is frozen.” Frozen /ˈfroʊ.zən/ means the device is not responding.
• “I have no signal.” Signal /ˈsɪɡ.nəl/ refers to a mobile or wireless connection.
• “Can you reset the router?” Reset /riːˈset/ means return a device or setting to a working starting state.
• “Try turning it off and on again.” This is common, simple advice because restarting can solve temporary problems.

How to make technology vocabulary stick

Do not try to memorize all 80 words in one session. Choose the words attached to your actual habits. If you use a phone mainly for videos and messaging, learn stream /striːm/, subscribe /səbˈskraɪb/, comment /ˈkɑː.ment/, mute /mjuːt/, and notification first.

Next, make a tiny routine. Change one device menu to English for five minutes, find five words from this list, and write one sentence for each. This turns abstract vocabulary into something you recognize under real time pressure.

Technology language also changes quickly. The Oxford English Dictionary tracks how established words gain new senses and how newer terms enter public use. Build a foundation with stable words such as file, folder, screen, and password, then notice newer expressions as they appear in conversation.

If online conversation feels too informal or confusing, read our English slang guide alongside this vocabulary. For number-heavy tech contexts such as storage, prices, dates, verification codes, and phone numbers, practice with English numbers from 1 to 100.

A practical study plan for this week

On day one, learn device and connection vocabulary. On day two, practice the verbs: download, upload, save, delete, install, update, click, and scroll.

On day three, describe what you do on your phone for two minutes in English. On day four, watch a short English video tutorial with captions and write down five terms you hear.

On day five, explain one minor technical problem aloud: “My Wi-Fi is slow,” “I cannot log in,” or “The app crashed.” On the weekend, review your screenshots, settings, and app menus in English.

Technology English becomes useful when it is connected to a real task. The goal is not to sound like an engineer. It is to understand the words that appear every day and to solve simple problems clearly when they matter.
