Although widespread use of the term data processing dates only from the 1950s, [2] data processing functions have been performed manually for millennia. For example, bookkeeping involves functions such as posting transactions and producing reports like the balance sheet and the cash flow statement.
Data has some inherent features when it is sorted on a key. All the values for subsets of the key appear together. When passing sequentially through groups of the data with the same key, or a subset of the key changes, this is referred to in data processing circles as a break, or a control break. It particularly facilitates the aggregation of ...
Any data input device that reads data from a card-shaped storage medium such as a memory card.

Also chip set.
Data processing system, a system which processes data which has been captured and encoded in a format style recognizable by the data processing system or has been created and stored by another unit of an information processing system; Electronic data processing, the use of automated methods to process data; Information and Software Technology ...
Names of many computer terms, especially computer applications, often relate to the function they perform, e.g., a compiler is an application that compiles (programming language source code into the computer's machine language). However, there are other terms with less obvious origins, which are of etymological interest. This article lists such ...
Information processing may refer to: Data processing in computer science, the collection and manipulation of digital data to produce meaningful information, esp. Electronic data processing, the use of automated methods to process data; Information processing (psychology) an approach to the goal of understanding human thinking
A data structure known as a hash table.. In computer science, a data structure is a data organization and storage format that is usually chosen for efficient access to data. [1] [2] [3] More precisely, a data structure is a collection of data values, the relationships among them, and the functions or operations that can be applied to the data, [4] i.e., it is an algebraic structure about data.
