arranged or happening in order
Happening or arranged one after another in a clear order.
用法パターン：
sequential [steps/events/tasks/items]
よくある間違い：
Learners sometimes mix up 'sequential' with 'consequential'. 'Sequential' means things come one after another in order. 'Consequential' means something is important or is a result of something. Also, some learners use 'sequence' as an adjective (e.g., 'sequence steps') instead of the correct 'sequential steps'.
類義語
consecutive (Focuses on things coming one directly after another, often in time, without gaps.)
|
ordered (More general; means arranged in some order, not always clearly step‑by‑step like 'sequential'.)
|
serial (Often used in technical or formal contexts for items in a series, sometimes more mechanical in tone.)
対義語
random (Suggests no fixed order or pattern, the opposite of being in a clear sequence.)
|
nonlinear (Used especially for stories or explanations that do not move step‑by‑step in time or logic.)

property
2
non-parallel, one-by-one processing
In technical subjects, working with things one by one instead of many at the same time.
用法パターン：
sequential [processing/access/circuit/algorithm]
よくある間違い：
Learners may assume 'sequential' in technical contexts always means 'slow', but it only describes the order of operations (one after another), not the absolute speed. Another confusion is treating 'sequential access' and 'random access' as the same; in fact, they are contrasting ways of reaching data.
類義語
serial (Very close in technical contexts; often used for data or processing handled one bit or item at a time.)
|
linear (Highlights a simple one‑direction flow, but may be broader and less strictly about timing than 'sequential'.)
対義語
parallel (In computing or electronics, refers to tasks or signals handled at the same time, the opposite of 'sequential'.)
|
random-access (In memory and storage, means you can reach any item directly, not by moving through them sequentially.)
