The Biodiversity Heritage Library website, an example of a digital library. A digital library (also called an online library, an internet library, a digital repository, a library without walls, or a digital collection) is an online database of digital objects that can include text, still images, audio, video, digital documents, or other digital media formats or a library accessible through the ...
Raymond A. Lorie, during his employment at IBM Research Centre Almaden, initiated the development of a UVC-based solution to long-term digital preservation. [2] He describes the approach as ‘Universal’ because its definition is so basic that it will endure forever, ‘Virtual’ because it will never have to be physically built and it is a ‘Computer’ in its functionality.
The earliest digital reference services were launched in the mid-1980s, primarily by academic and medical libraries, and provided by e-mail.These early-adopter libraries launched digital reference services for two main reasons: to extend the hours that questions could be submitted to the reference desk, and to explore the potential of campus-wide networks, which at that time was a new technology.
Mac OS X has built-in PDF support, both for creation as part of the printing system and for display using the built-in Preview application. Older PDF files are supported by almost all modern e-book readers, tablets and smartphones. Newer PDF files may not display properly on older e-readers, may not open, or may crash them.
In this same context, the Virtual Environment would include a doctor practicing CPR on a training mannequin, and the Constructive Environment is the software within the training mannequin that drives its behavior. In a second example, consider fighter pilot training or operational testing. The Live environment is the pilot flying the combat ...
A virtual environment is a networked application that allows a user to interact with both the computing environment and the work of other users. Email, chat, and web-based document sharing applications are all examples of virtual environments. Simply put, it is a networked common operating space.
The cornerstone of digital preservation, "data integrity" refers to the assurance that the data is "complete and unaltered in all essential respects"; a program designed to maintain integrity aims to "ensure data is recorded exactly as intended, and upon later retrieval, ensure the data is the same as it was when it was originally recorded".
A digital environment is an integrated communications environment where digital devices communicate and manage the content and activities within it. The concept is based on digital electronics systems which are integrated and implemented for a global community. [ 1 ]
