20 cards. Read the term and the definition here. The deck at the top of this page is optional.
- CPU
- The processor component that executes machine instructions and coordinates operations under the computer architecture, distinct from memory that stores working state or devices that display results.
- RAM
- Working memory used by running programs and system services, commonly volatile in personal computers. Its role differs from persistent storage and from a CPU cache.
- Device driver
- Software providing the operating-system interface to a supported hardware device, with compatibility and trusted installation requirements that depend on the actual device and platform.
- File extension
- A suffix commonly used for application association or a format hint. It does not prove the file’s actual content or convert its representation when renamed.
- Backup
- A planned recoverable copy or history with protection appropriate to the expected loss scenarios, whose value depends on verified restoration rather than a success message alone.
- Paragraph style
- A named set of paragraph and related formatting rules that can be applied consistently, enabling structural changes without manually editing every matching heading or paragraph.
- Section break
- A document boundary that can permit different page-level settings in the following section, with behavior governed by the actual word processor and section options.
- Mail merge
- Combining a main document with structured recipient records to create personalized output, requiring verification of fields, selection, missing data and resulting documents before distribution.
- Tracked changes
- A review feature recording proposed edits for inspection and acceptance or rejection, distinct from establishing that the resulting document has received final authorization.
- Absolute reference
- An Excel-style cell reference whose fixed row and column are marked with dollar signs, preserving that location when the formula is copied under the stated model.
- Mixed reference
- A reference fixing either the row or the column while allowing the other coordinate to change, useful when a copied formula needs one stable relationship.
- Cell format
- Display and presentation instructions such as number format, alignment or borders. Formatting can change what a user sees without changing the underlying stored numeric value.
- Filter
- A selection view showing rows that meet conditions while retaining other records in the underlying table, unlike a deletion that removes data from the selected structure.
- Chart series
- A related set of plotted values associated with labels or positions, whose source range, units and ordering must match the intended comparison.
- Slide master
- A shared presentation design layer influencing layouts and slides that use it, useful for consistent structure without guaranteeing that every independent object changes automatically.
- Primary key
- A chosen minimal identifying key enforced as unique and nonnull for a table, which can consist of one column or a declared combination.
- Database query
- A request or stored definition selecting or transforming information under the database model, distinct from the table storing records or a form presenting data entry.
- URL
- An address describing a resource and its access scheme, host and other components as applicable, rather than merely a displayed page title or search result label.
- Phishing
- A deceptive attempt to imitate a trusted interaction and obtain information or induce an unsafe action, requiring assessment of actual context and destination rather than branding alone.
- Lossless compression
- A representation allowing exact reconstruction of the encoded data under the scheme, with achievable size reduction depending on the source rather than a guaranteed ratio.
