sequential access is a method of data access where information in a storage device is accessed in a sequence or order. it's like listening to songs on a cassette tape; you must go through each song to reach the one you want. this is different from random access where any data can be ...
processing is often used when performing input and output (I/O) operations. For example, when reading a file sequentially, data is read one item at a time from the beginning to the end. Similarly, when writing data sequentially, it is written in a specific order, preserving the sequence. ...

Here are a few prominent conceptual and functional differences between general purpose programming languages and QL:QL does not have any imperative features such as assignments to variables or file system operations. QL operates on sets of tuples and a query can be viewed as a complex sequence ...
2. In an SQL (Structured Query Language) database, a sequence is used to generate a unique number and starting point, which is then increased based on a set interval. A sequence creates a primary key value in a database table, and is incremented by one with each newly generated data...
Next-generation sequencing (NGS) is a technology for determining the sequence of DNA or RNA to study genetic variation associated with diseases or other biological phenomena. Introduced for commercial use in 2005, this method was initially ...
(1)One of the three basic logic structures in computerprogramming. The other two logic structures areselectionandloop. In asequencestructure, an action, orevent, leads to the next ordered action in a predetermined order. The sequence can contain any number of actions, but no actions can be ...
As an example, when a programmer types a sequence ofC programming languagestatements into Windows Notepad and saves the sequence as a text file, the text file now contains source code. Source code andobject codeare sometimes referred to as thebeforeandafterversions of a compiled computer program....
In computer science, a thread typically refers to a sequence of software codethe computer and its CPU must execute. In programming, a thread is the smallest series of related instructions involved in a process, which can involve many threads. For example, a thread may involve a small subroutin...
