In computing, a scalar is a variable or field that can hold only one value at a time; as opposed to composite variables like array, list, record, etc. A variable (ˈvɛərɪəbl is an Attribute of a physical or an abstract System which may change its Value while it is under Observation. In Computer science, data that has several parts can be divided into fields. In Computer science an array is a Data structure consisting of a group of elements that are accessed by indexing. In Computer science, a list is an ordered collection of entities / Items In the context of Object-oriented programming languages In Computer science, object composition (not to be confused with function composition) is a way and practice to combine simple objects or In some contexts, a scalar value may be understood to be numeric. A scalar data type is the type of a scalar variable. For example, char, int, float, and double are the most common scalar data types in the C programming language. tags please moot on the talk page first! --> In Computing, C is a general-purpose cross-platform block structured

The origin of the term "scalar" in computing dates back to the 1970s, where the intended meaning was "opposite of vector", so as to distinguish from the idea of vector processing in computer processor design. In Computer science, a dynamic array, growable array, resizable array, dynamic table, or array list is an Array A vector processor, or array processor, is a CPU design where the instruction set includes operations that can perform mathematical operations on multiple data
