linearsequential

Linearsequential is a term used in computer science to describe a data organization and access pattern that combines a linear arrangement of elements with sequential processing. The term merges linear (an ordered structure) with sequential (processing in a fixed, single pass) to emphasize sustained, forward-only traversal.

Core characteristics include: elements stored in a linear order, such as an array or contiguous buffer; access that proceeds from the first element to the last without random jumps; strong spatial locality and cache friendliness; minimal indexing and simple control flow; well suited to streaming data and single-pass algorithms.

Common contexts for linearsequential patterns include memory layouts optimized for sequential prefetching, input/output pipelines that read data line by line, and buffers used in real-time or streaming processing. Examples include iterating a fixed-size array from start to finish, reading a log file line by line, or applying a filter to a data stream in a single pass.

Advantages are predictable performance, low overhead, and efficient use of cache and memory bandwidth. Limitations include poor suitability for random access workloads, difficulty in inserting or deleting elements in the middle of an active sequence, and potential inefficiency when the exact size is unknown or frequently changing.

Relation to related concepts: linearsequential differs from general random-access data structures but overlaps with linear data layouts and sequential access patterns. It is often discussed in the context of data locality, streaming algorithms, and design of cache-friendly data processing pipelines.
