A phone can be beautifully quick at showing a button and surprisingly vague about what happened after you pressed it. This guide teaches 100 digital technology vocabulary words with meanings, collocations and original examples, so you can explain devices, networks, data and permissions—and read a service message without turning “received” into “approved.”
South Korea offers useful contexts through electronics and telecommunications research, digital-policy discussions, cybersecurity institutions and services that need to handle Korean and other languages. These contexts give general English technology terms practical questions. They do not mean that every person has the same access, confidence, device or experience of digital life.
Follow one task from input to response, choose the relevant word group and retrieve five terms without the table. Then explain the task to a reader who needs plain language. “Top 100” is a curated learning list, not a measured frequency ranking. All services, dialogue, status messages and datasets below are invented for practice; the linked primary sources support the technical concepts.

Read these invented messages: “You are signed in”; “You may view this record”; “Your submission has been received.” Do they establish that you may edit the record or that the submission has been approved? No. Identity, permission and process status are distinct meanings. That is the first useful diagnostic, even before a reader meets the word authorization.
Ask the learner to sketch a phone, a network connection, a server and a stored record. Draw a request towards the server and a response back. If the learner knows every label but puts the saved record inside the button, practise the relationship. If the relationship is clear but server and browser are hard to retrieve, practise naming and explaining.
Students can underline the action and its status in each message. Parents can ask “What exactly has been confirmed?” Teachers can collect a short unaided explanation before providing a model. Good digital vocabulary is not measured by the number of acronyms remembered; it helps the reader understand what happened and what remains uncertain.
Hardware, working memory, storage and a display are different parts of the story. The English terms are general; South Korea provides a context through electronics and digital-service research.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 1. digital | Representing or processing information through discrete values, commonly binary in computing. | digital service | The Seoul learning scene follows a digital service from the screen to its stored record. |
| 2. device | A piece of equipment performing a specified function. | mobile device | The visitor uses a mobile device to read the museum’s message. |
| 3. hardware | The physical components of a computer or other digital system. | computer hardware | The explanation separates hardware from the application running on it. |
| 4. processor | A component that executes instructions and performs computing operations. | central processor | The diagram places the processor inside the device. |
| 5. semiconductor | A material whose electrical properties can be controlled, fundamental to many electronic components. | semiconductor material | The Korean research paragraph discusses a semiconductor without treating it as an entire computer. |
| 6. chip | An electronic component containing a circuit, commonly an integrated circuit. | integrated-circuit chip | The label distinguishes a chip from the finished phone. |
| 7. memory | Computer storage used to hold information for processing, often referring to working memory. | working memory | The exercise separates working memory from a long-term saved file. |
| 8. storage | Keeping digital information for later access. | local storage | The diagram contrasts local storage with a remote service. |
| 9. display | A screen or system presenting visual information. | display resolution | The visitor enlarges the text on the display. |
| 10. input | Information or signals supplied to a system. | user input | The form checks the input before accepting the request. |
An application, operating system, version and update are related but not interchangeable. A support explanation needs the relevant version and conditions rather than a vague report that everything changed.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 11. software | Programs and related instructions enabling digital equipment to perform tasks. | application software | The software handles the form after the user enters the information. |
| 12. application | Software designed for a particular user task or purpose. | mobile application | The application shows a status message after submission. |
| 13. operating system | Software managing device resources and providing services for other software. | device operating system | The notice distinguishes the operating system from the gallery application. |
| 14. interface | A boundary or means through which people or systems interact. | user interface | The interface should explain what the button will do. |
| 15. installation | Adding and configuring software for use on a system. | software installation | The example separates installation from opening an already installed application. |
| 16. update | A change to a system or its software, often supplying fixes or new behaviour. | software update | The notice describes the update without promising that every problem is solved. |
| 17. version | An identified state or release of software or another digital artefact. | application version | The support note records the version involved. |
| 18. compatibility | The ability of components or systems to work together under relevant conditions. | device compatibility | The help text states compatibility requirements rather than assuming every device works. |
| 19. configuration | The settings and arrangement determining how a system operates. | system configuration | The analyst records the configuration before comparing results. |
| 20. default | A preset value or behaviour used unless another is chosen. | default setting | The learner checks the default instead of assuming it is a personal choice. |
Bandwidth and latency answer different questions. A network connects systems; it does not grant every user permission. Avoid turning connectivity into a claim that all people have the same access.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 21. network | Connected devices or systems able to exchange information. | computer network | The diagram distinguishes the network from any one connected device. |
| 22. internet | The global system of interconnected networks using common internet protocols. | internet connection | An internet connection does not automatically grant permission to edit the record. |
| 23. bandwidth | A connection’s data-carrying capacity in computing usage, or a frequency range in other technical contexts. | network bandwidth | The report distinguishes available bandwidth from measured transfer speed. |
| 24. latency | Delay between a stated event and the relevant response or arrival. | network latency | The log records latency rather than calling every delay a slow processor. |
| 25. packet | A formatted unit of data transmitted through a network. | data packet | The diagram divides the transmission into packets. |
| 26. protocol | Agreed rules for communication between systems. | network protocol | The systems need a compatible protocol to exchange the message. |
| 27. router | A device directing data between networks. | network router | The sketch shows a router connecting the local network to another. |
| 28. wireless | Communicating without a wired connection, commonly through radio signals. | wireless connection | The device uses a wireless connection in the reading example. |
| 29. cellular | Relating to mobile communication networks organised around coverage cells. | cellular network | The visitor distinguishes a cellular network from the museum’s local wireless network. |
| 30. connectivity | The ability or condition of systems being connected and communicating. | network connectivity | The message reports a connectivity problem without diagnosing its cause. |
The browser, server and stored record perform different roles. A timeout can leave the outcome uncertain. Read the response and verify state rather than inventing success or failure.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 31. browser | Software used to retrieve and present web content. | web browser | The visitor opens the guide in a browser rather than a separate installed application. |
| 32. server | A system or program providing services to other systems. | web server | The server returns a response to the browser’s request. |
| 33. client | A system or program requesting or using another system’s service. | client application | The diagram marks the browser as a client in this exchange. |
| 34. request | A message asking a system to perform an action or return information. | server request | The browser sends a request when the button is pressed. |
| 35. response | Information returned after a request or action. | server response | The learner reads the response before deciding whether the task succeeded. |
| 36. upload | Transfer data from a local system to another system, often a server. | upload a file | The user uploads the drawing to the demonstration service. |
| 37. download | Transfer data from another system to the local system. | download a document | The visitor downloads the published guide for later reading. |
| 38. cloud computing | On-demand access to shared computing resources through a network, under the relevant service model. | cloud service | The diagram describes a cloud service without imagining a single invisible computer. |
| 39. cache | A store of information kept to make later access faster or reduce repeated work. | browser cache | A cached page may differ from the latest stored record. |
| 40. API | Application programming interface: a defined way for software components to interact. | service API | The developers use an API to exchange the required information. |
Korean and English text make character representation a useful practical question. Unicode is not the same thing as a particular font. Data needs structure and scope to remain meaningful.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 41. data | Recorded values or information used by a system or analysis. | stored data | The exercise checks which data the service actually records. |
| 42. database | An organised collection of data managed for access and use. | service database | The database stores the accepted submission. |
| 43. record | A stored unit of information describing an item or event. | submission record | The support note looks for the record before repeating the action. |
| 44. field | A named element of a record or form holding a particular value. | date field | The form’s date field needs a clear expected format. |
| 45. metadata | Information describing other data, such as origin, format or time. | file metadata | The reviewer checks metadata alongside the file’s visible content. |
| 46. format | An agreed structure or representation for information. | file format | The upload accepts the stated file format. |
| 47. character encoding | Rules representing characters as values or bytes in a digital system. | text character encoding | The team checks character encoding when Korean text displays incorrectly. |
| 48. Unicode | A standard assigning characters identities and code points for consistent text representation. | Unicode text | Unicode helps represent Korean and English text within the same document. |
| 49. dataset | A defined collection of data used for analysis or another purpose. | training dataset | The analyst describes the dataset’s scope before discussing the result. |
| 50. data quality | The fitness of data for a specified use, considering properties such as correctness and completeness. | check data quality | More records do not automatically mean better data quality. |
CHAPTER 7 OF 18 · WORD GROUP 6 OF 10
Separate identity, permission and information protection
A signed-in user may still lack editing rights. Encryption and privacy also do different jobs. This is vocabulary learning, not a procedure for testing or bypassing a live system.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 51. authentication | Checking a claimed identity or the authenticity of information through an appropriate process. | user authentication | Authentication checks who is signing in, not every action they may perform. |
| 52. authorization | Granting or checking permission for a specified action or resource. | editing authorization | The user is signed in but has no authorization to edit this record. |
| 53. credential | Evidence or information used to support an identity or access claim. | account credential | The learning dialogue discusses a credential without displaying a real secret. |
| 54. password | A secret value used in some authentication processes. | account password | The notice refers to a password without asking the class to share one. |
| 55. multi-factor authentication | Authentication using more than one distinct category of evidence or factor. | enable multi-factor authentication | Two passwords alone do not necessarily constitute multi-factor authentication. |
| 56. encryption | Transforming information using cryptographic methods so recovery requires the relevant key or process. | data encryption | Encryption protects the data’s readable form under the stated design. |
| 57. privacy | Appropriate control and treatment of information about people in its relevant context. | data privacy | The design discussion asks how privacy is affected by collecting a birth date. |
| 58. permission | An allowed action or access right. | application permission | The learner reads the permission requested before explaining its purpose. |
| 59. vulnerability | A weakness that could be exploited or contribute to harm in a system. | software vulnerability | The report distinguishes a vulnerability from an observed attack. |
| 60. phishing | Deceptive communication intended to make someone disclose information or take a harmful action. | phishing message | The fictional phishing example is labelled as a classroom illustration. |
Usability, accessibility and localisation concern real readers. A translated message must preserve its status meaning; a beautifully short button can still be ambiguous.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 61. navigation | The routes and controls used to move through an interface or information space. | clear navigation | The visitor follows the navigation to the language options. |
| 62. accessibility | The ability of people with different needs to perceive, operate and understand a system. | digital accessibility | The design review includes digital accessibility as a requirement. |
| 63. usability | How effectively and satisfactorily intended users can complete tasks in a defined context. | usability test | A beautiful screen can still perform poorly in the usability test. |
| 64. responsive design | An approach adapting an interface’s presentation to different display sizes or conditions. | responsive web design | The sketch shows responsive design on a phone and a larger screen. |
| 65. localisation | Adapting a product or service for a language, region or audience. | Korean localisation | Localisation considers wording and date presentation as well as translation. |
| 66. translation | Expressing information in another language while preserving the relevant meaning. | interface translation | The translation keeps the distinction between submitted and approved. |
| 67. notification | A message informing a user about an event or condition. | status notification | The notification tells the user what happened and what comes next. |
| 68. error message | A message describing a failed or invalid condition in a system. | clear error message | The error message identifies the rejected file format. |
| 69. confirmation | An acknowledgement that a specified action or condition has been established. | submission confirmation | The confirmation records receipt, not automatic approval. |
| 70. consent | Agreement to a specified action or use under the relevant conditions. | informed consent | The design exercise explains what the user is being asked to consent to. |
Artificial intelligence is broader than one method. Training, inference and evaluation belong to different stages. South Korea’s digital-policy and research accounts are contexts, not guarantees about a particular product.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 71. algorithm | A defined procedure for performing a task or solving a problem. | search algorithm | The explanation identifies the algorithm’s task rather than calling it intelligence by itself. |
| 72. artificial intelligence | Computer systems performing tasks associated with capabilities such as prediction, language processing or decision support. | AI system | The Korean research text describes an AI system with a stated purpose. |
| 73. machine learning | Methods that derive patterns or models from data for tasks such as prediction. | machine-learning model | The model’s performance needs a defined task and test. |
| 74. model | A representation or computational system used to describe, predict or generate outputs. | prediction model | The model is checked against relevant evidence. |
| 75. training | The process of fitting or developing a machine-learning model using data and a defined method. | model training | The report separates training from the later evaluation. |
| 76. inference | Using a trained model to produce an output for new input in this computing context. | model inference | The diagram puts inference after the training stage. |
| 77. prediction | An estimated outcome produced from evidence or a model. | model prediction | A prediction is not the same as a confirmed observation. |
| 78. classification | Assigning an item to a category according to a rule or model. | image classification | The task uses classification to assign images to stated categories. |
| 79. bias | A systematic tendency affecting data, decisions or results; the intended sense must be stated. | model bias | The evaluation asks which groups or conditions the model bias affects. |
| 80. evaluation | Assessment against defined criteria using appropriate evidence. | model evaluation | The evaluation uses a different task question from merely describing the training data. |
An outage, a slow response and an incorrect result are different problems. Backup and redundancy support resilience under particular designs; neither word promises uninterrupted service.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 81. reliability | The ability of a system to perform its intended function under stated conditions. | service reliability | The report states the period and conditions behind the reliability claim. |
| 82. availability | The extent to which a service is accessible and usable when required. | service availability | The status note distinguishes availability from the correctness of a response. |
| 83. backup | A retained copy of data used to support recovery. | data backup | The backup record states what was copied and when. |
| 84. recovery | Restoring data or service after a loss or disruption. | service recovery | The team checks recovery rather than assuming a backup guarantees it. |
| 85. redundancy | Additional components or information intended to support operation if another part fails. | system redundancy | The diagram shows redundancy alongside its remaining shared dependency. |
| 86. outage | A period during which a service is unavailable. | network outage | The fictional notice gives the outage’s observed scope. |
| 87. monitoring | Repeatedly observing a system’s condition or performance. | service monitoring | Monitoring records the response time and the observation period. |
| 88. log | A recorded sequence of system events or other information. | event log | The log helps establish what happened before the error. |
| 89. incident | An event requiring attention because it affects or may affect the expected operation or security. | service incident | The report defines the incident before discussing its impact. |
| 90. patch | A change intended to fix a software issue or vulnerability. | security patch | The patch addresses the stated issue without promising perfect security. |
CHAPTER 11 OF 18 · WORD GROUP 10 OF 10
Connect a service with people and responsibility
Digital literacy includes judgement about what a system has established. Access, skills, responsibilities and records matter alongside technical capability.
| Vocabulary word | Meaning in this context | Natural collocation | Original example sentence |
|---|---|---|---|
| 91. digital literacy | The knowledge and judgement needed to use and understand digital technologies appropriately. | digital-literacy practice | Digital literacy includes interpreting the message rather than only pressing the button. |
| 92. digital divide | Differences in access to or effective use of digital technologies and related opportunities. | digital divide | The discussion asks which access and skill differences are involved in the digital divide. |
| 93. platform | A system supporting services, applications or interaction among users and other participants. | digital platform | The paragraph identifies what the platform enables. |
| 94. transaction | A defined exchange or operation, often involving a change to recorded state. | online transaction | The support note checks whether the transaction completed before retrying it. |
| 95. interoperability | The ability of systems to exchange and use information effectively. | data interoperability | Interoperability needs shared meanings as well as a connection. |
| 96. automation | Using systems to carry out tasks with reduced direct human action. | workflow automation | The team states which step the automation performs. |
| 97. audit trail | Records allowing actions and changes to be followed and examined. | digital audit trail | The audit trail connects a change to its recorded event. |
| 98. accountability | Responsibility for decisions and the obligation to explain them. | digital accountability | The discussion asks who is accountable for the service’s decision. |
| 99. verification | Checking whether a claim, result or requirement is supported. | status verification | The learner verifies the stored status rather than relying on an uncertain screen. |
| 100. innovation | A new or substantially improved approach put into use within a relevant context. | digital innovation | The article discusses innovation through a concrete task rather than a national stereotype. |
The Electronics and Telecommunications Research Institute’s official site supplies a research context spanning electronics and communications. Its telecommunications and media research account connects communication infrastructure with media and content. Research subjects provide learning contexts; they are not proof that every technology is already deployed everywhere.
South Korea’s Ministry of Science and ICT published Digital Strategy of Korea, a roadmap announced in September 2022. Its priorities give a useful setting for AI, semiconductors, connectivity and digital participation vocabulary. Keep a roadmap’s announced aims separate from independently measured completion or a claim about today’s entire population.
The Korea Internet & Security Agency provides a Korean institutional context for digital security. For selected English meanings, NIST’s authentication and authorization entries help separate identity checks from allowed actions. NIST is a United States institution; the terms are used here as technical references rather than Korean legal requirements.
The Unicode Consortium’s Korean text FAQ makes character representation a particularly useful country-context question. A character’s encoded identity, the bytes used to represent it and the font’s visible shape are related but different. That distinction helps explain why localisation involves more than translating a button.
The recently published South Korea learning guide includes Hangul and different regional cultural environments. Connect that variety with digital reading: a museum description, a classroom task and a service form have different audiences and language needs.
Sources were reviewed on 15 October 2026. This guide does not announce a current connectivity ranking, adoption percentage, product specification or software release. Its examples use general concepts and explicitly invented systems.
CHAPTER 13 OF 18
Worked service journey: the screen has timed out, but what is known?
Original practice scene: Min uploads a drawing to an imaginary exhibition service. The screen says “Request timed out.” A later view of the service’s record list shows one entry with Min’s submission identifier and status received. No selection decision is displayed. Min writes, “The upload failed, so I submitted it again and the exhibition accepted me.” The first error is treating an uncertain response as a settled failure; the second is treating receipt as approval.
Read the evidence in order. A timeout says the expected response was not obtained within the relevant interval. The later stored record establishes that one identified submission was received in this invented service. The status does not establish selection. A careful explanation is “The initial screen left the outcome uncertain. The record list later showed one received submission; approval is not stated.”
Now try an invented dialogue. Min: “I am signed in, so why can’t I change the record?” Support reader: “Signing in concerns authentication. The record’s editing permission concerns authorization.” Min: “Does the view button mean I have editing permission?” Reply: “No. The available action is view.” A few terms prevent an entire inaccurate help message.
Write a useful status note: “Submission S-14 appears once in the record list with status received. The displayed page does not show an approval decision or an editing option.” The note gives an identifier and observed status without exposing a real account or inventing a support contact.
Change one condition for transfer: the later page is a previously stored browser copy rather than a freshly obtained response. Now a cache question matters. The reader should not assume the old view proves current state. MDN’s HTTP caching guide explains why stored responses and their reuse need a defined freshness context. We use that concept for reading, without prescribing a particular live service’s recovery procedure.
Hardware is physical equipment; software provides programs and related instructions. An application serves a user task, while an operating system manages resources and services for applications. Installation, update and configuration describe different changes. A support note becomes much more useful when it identifies which one occurred.
Bandwidth concerns data-carrying capacity in this computing usage; latency concerns a delay between stated events. A larger capacity does not remove every delay. MDN’s latency glossary supplies a concise technical reference. State the measured start and end rather than say “the internet is slow” as if that identified the cause.
Authentication checks an identity or authenticity claim; authorization concerns permitted access or actions. Encryption transforms information using cryptographic methods. Privacy concerns appropriate treatment of personal information in context. A secure-looking sign-in page does not by itself settle all four questions.
Unicode assigns character identities and code points; a font supplies visual glyphs; an encoding form represents characters in units or bytes. The Unicode basic FAQ explains why the standard does not define every aspect of layout or appearance. Korean localisation may also need understandable language choices and date or form conventions.
Training develops a machine-learning model from data under a method. Inference uses the trained model for new input. Evaluation assesses performance against a defined task and criteria. NIST’s AI technology evaluation account provides a primary context for task- and dataset-specific assessment. A prediction is an output to examine, not a confirmed observation merely because it came from a model.
Register can stay humane. “The system received your file; a decision is still pending” may be better than a dense paragraph about transaction states. Learn the technical meaning, then choose the plain sentence that helps the actual user. Shortening a message should not remove the status distinction.
1. A user is authenticated and permitted to view a record. Does that establish permission to edit it? 2. A message says received. Does it establish approved? 3. Which term names delay: latency or storage? 4. Is Unicode itself a font? 5. In machine learning, which stage uses a trained model for new input?
6. Rewrite “The request timed out, therefore nothing was saved” when no stored-state evidence is available. 7. A report says a model correctly classified 18 of 20 items in an invented test. State the test proportion, then name a conclusion the result does not establish. 8. Write a plain-English confirmation distinguishing receipt from selection.
Answers and checking notes: 1. No: viewing and editing permissions differ. 2. No. 3. Latency. 4. No: character representation and visible font design are distinct. 5. Inference. 6. Example: “The request timed out, so this response does not establish whether the item was saved.” 7. 90% in that specified test: 18 ÷ 20. It does not establish performance for every user, dataset or task. 8. Example: “Your drawing has been received; the message does not state a selection decision.”
Choose five terms from a group and explain one service journey without the table. Later, use a new journey with different permissions or a changed status. On a further review, give a thirty-second explanation to someone who does not know the technical vocabulary. The new conditions should change the answer when they change the meaning.
Create a fictional help card for an exhibition submission. Include the accepted input, the meaning of received, the difference between viewing and editing, and what information a user should supply in a status question. Use invented identifiers only. The task requires no real credentials, messages or system changes.
For a parent, ask whether the explanation makes the next question clear. For a teacher, rotate roles of status reader, permission reader and plain-language editor. Then give each student a fresh notice to explain independently. For students, keep a first answer and a revision showing where an overclaim was removed.
The South Korea English learning guide separates understanding a passage from preserving a limiting word in a summary. Digital messages offer compact practice: may, received, pending and available can control the whole conclusion. Use the learner’s actual grade, course and task for assessment planning rather than assume a technical word list is a CSAT specification.
This vocabulary supports science and technology reading, service communication, digital-literacy discussion and career exploration. It does not establish a software qualification, product endorsement, local eduKate operation or a promised employment route.
Are all the words Korean? No. They are English technology terms contextualised through South Korean research, language needs and digital-service questions. The article does not require a list of untranslated Korean labels.
Does using a phone fluently mean I know the vocabulary? It shows practical familiarity with some tasks. Explaining permissions, uncertainty or a data claim may require other language and concepts.
Does two-step always mean multi-factor? Not necessarily. Multi-factor concerns distinct categories of authentication evidence, not merely the number of screens or repeated use of the same factor.
Can a model’s test result prove general accuracy? A result needs its task, dataset, method and relevant limitations. One classroom proportion is not universal performance.
Are the service records and messages genuine? No. The exhibition, identifier and test results are invented for reading and vocabulary practice.
Use groups 1–2 to explain a device or software notice. Choose groups 3–5 to follow a request and its data. Use groups 6–7 for permissions and user messages. Groups 8–10 help with AI outputs, reliability and accountability questions.
Your next independent task is to write four sentences about a fictional service: what the user requested, what was observed, what permission exists and what remains unknown. Include five terms naturally, then turn the account into a short friendly explanation.
Continue through the eduKate vocabulary learning hub for collocations, retrieval and transfer. Bring the new notice and your explanation to a learning discussion. One correctly preserved status can make an entire response more useful.
