Schemes for data retention do not make provisions for adequate regulation of the data retention process and for independent judicial oversight. [citation needed] Data retention is an invasion of privacy and a disproportionate response to the threat of terrorism. [citation needed] It is easy for terrorists to avoid having their communications ...
Digital computers, in particular, make use of two forms of memory known as RAM or ROM and although the most common form today is RAM, designed to retain data while the computer is powered on, this was not always the case. Nor is active memory the only form used; passive memory devices are now in common use in digital cameras.
After such a file is created, typical operation is to present it as a slide show using a portable computer, where the presentation file is stored on the computer or available from a network, and the computer's screen shows a "presenter view" with current slide, next slide, speaker's notes for the current slide, and other information.

In computer science, resource contention is a conflict over access to a shared resource such as random access memory, disk storage, cache memory, internal buses or external network devices. A resource experiencing ongoing contention can be described as oversubscribed.
In 2014, the National Digital Stewardship Alliance recommended developing file format action plans, stating "it is important to shift from more abstract considerations about file format obsolescence to develop actionable strategies for monitoring and mining information about the heterogeneous digital files the organizations are managing".

Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data.
RAM drive – a block of random-access memory that the operating system treats as if it were secondary storage; Sequential access memory – a class of data storage devices that read stored data in a sequence; Wear leveling – a technique for prolonging the service life of some kinds of erasable computer storage media, such as flash memory
Confidential computing can be used in conjunction with storage and network encryption, which protect data at rest and data in transit respectively. [ 1 ] [ 2 ] It is designed to address software, protocol, cryptographic, and basic physical and supply-chain attacks, although some critics have demonstrated architectural and side-channel attacks ...
