An interrogative clause is a clause whose form is typically associated with question-like meanings.

- Interrogative

One for which the questioner does not expect a direct answer: in many cases it may be intended to start a discourse, or as a means of displaying or emphasize the speaker's or author's opinion on a topic.

- Rhetorical question

Form of complex question that contains a controversial assumption .

- Loaded question

Processed, organized and structured data.

- Information

Questions are often conflated with interrogatives, which are the grammatical forms typically used to achieve them.

- Question

Rhetorical questions, for example, are interrogative in form but may not be considered true questions as they are not expected to be answered.

- Question

Loaded questions (a special case of complex questions), such as "Have you stopped beating your wife?"

- Question

This often indicates a question to which no answer is expected, as with a rhetorical question.

Complex question

A journalist raises her hand to ask a question at a press conference.

A complex question, trick question, multiple question, fallacy of presupposition, or plurium interrogationum (Latin, 'of many questions') is a question that has a presupposition that is complex.

When a presupposition includes an admission of wrongdoing, it is called a "loaded question" and is a form of entrapment in legal trials or debates.

Data storage

DNA and RNA can be considered as biological storage mediums.
Various electronic storage devices
Edison cylinder phonograph c. 1899. The phonograph cylinder is a storage medium. The phonograph may be considered a storage device especially as machines of this vintage were able to record on blank cylinders.
On a reel-to-reel tape recorder (Sony TC-630), the recorder is data storage equipment and the magnetic tape is a data storage medium.

Data storage is the recording (storing) of information (data) in a storage medium.


Shannon and Weaver Model of Communication

In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium.

Data are individual facts, statistics, or items of information, often numeric.


In The Signal by William Powell Frith, a woman sends a signal by waving a white handkerchief.
A digital signal has two or more distinguishable waveforms, in this example, high voltage and low voltages, each of which can be mapped onto a digit. Characteristically, noise can be removed from digital signals provided it is not too extreme.
A binary signal, also known as a logic signal, is a digital signal with two distinguishable levels
Discrete-time signal created from a continuous signal by sampling
Signal transmission using electronic signals

In signal processing, a signal is a function that conveys information about a phenomenon.

Information theory

A picture showing scratches on the readable surface of a CD-R. Music and data CDs are coded using error correcting codes and thus can still be read even if they have minor scratches using error detection and correction.

Information theory is the scientific study of the quantification, storage, and communication of digital information.

Information Age

Historical period that began in the mid-20th century, characterized by a rapid epochal shift from traditional industry established by the Industrial Revolution to an economy primarily based upon information technology.
