CHARACTERISTICS OF DIGITAL INFORMATION
Digital describes electronic technology that generates, stores, and processes data in terms of two states:
positive and non-positive.
What is Digital Information1.
Machine language; data stored in zeros and ones.
2.
Information that is in digital, electronic form and is stored, manipulated, and displayed by computational tools.
Digital information is stored using a series of ones and zeros. Computers are digital machines because they can only read information as on or off -- 1 or 0. This method of computation, also known as the binary system, may seem rather simplistic, but can be used to represent incredible amounts of data.
Digital technology is primarily used with new physical communications media, such as satellite and fiber optic transmission. A modem is used to convert the digital information in your computer to analog signals for your phone line and to convert analog phone signals to digital information for your computer.
Digital data, in information theory and information systems, is the discrete, discontinuous representation of information or works. ... The term is most commonly used in computing and electronics, especially where real-worldinformation is converted to binary numeric form as in digital audio and digitalphotography.
Relevant characteristics of digital information
Digital information is very different from its physical counterpart. Physical information has a fixed position in place and time. This is not the case with digital information, which can be:
rapidly duplicated and easily distributed
e.g. a message posted via social media is reposted elsewhere by friends or an email sent to a list of recipients within a very short time frame
stored in multiple locations
e.g. a photo can be stored simultaneously on a laptop, a smartphone and in the Cloud
created and communicated automatically
e.g. a smartphone can synchronise emails with another device or an online service
stored with varying levels of 'discoverability'
e.g. image files that can only be accessed using a password or other method of authentication.
DIGITAL INFORMATION CAN BE COMMUNICATED RAPIDLY
The 'viral' nature of digital communication enables information to spread rapidly and reach a wide audience. This can make it very difficult to know who has received the information or how it will spread further. It also requires any action to minimise harm that could be caused by this communication to be taken quickly.
DIGITAL INFORMATION IS HARD TO PERMANENTLY DELETE
Once digital information or items are created it can be difficult, if not impossible, to permanently delete all copies. For example digital information can be:
stored on a range of digital devices such as smartphones, laptops and internet servers as it is communicated. For example an email or chat message.copied and communicated automatically or to a schedule making it difficult to know what information is stored where. For example, a smartphone automatically synchronising stored information with a laptop computer or to the 'Cloud'.
retrieved or restored from the archive or trash after deletion using easily accessible tools.
temporarily stored on a device. For example, a device will download information to display a website and then can delete it when the web browser is closed.
DIGITAL INFORMATION CAN BE REMOTELY ACCESSED
Typically, transmitting digital devices such as smartphones or laptops can be accessed remotely via another internet connection. Similarly, the content of a website can be remotely accessed and edited. Example of actions that can be carried out remotely include:
deleting, adding or editing information stored on a digital device or web page
accessing a device's location services to find its specific location, or
turning on a device's web camera and using it to record.
