Persistence in computer science refers to the characteristic of data that outlives the execution of the program that created it. Without this capability, data would only exist in RAM, and would be lost when this RAM loses power, such as on computer shutdown....

Capability-based security is a concept in the design of secure computing systems. A capability is a communicable, unforgeable token of authority. It refers to a value that references an object along with an associated set of access rights. A user program on a capability-based operating system must...

An operating system is an interface between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of the computer that acts as a host for computing applications run on the machine. As a host, one of the purposes of an operating...

International Business Machines Corporation, abbreviated IBM, is a multinational computer technology and IT consulting corporation headquartered in Armonk, Town of North Castle, New York, United States. The company is one of the few information technology companies with a continuous history dating...

IBM mainframes, though perceived as synonymous with mainframe computers in general due to their marketshare, are now technically and specifically IBM's line of business computers that can all trace their design evolution to the IBM System/360....

A computer is a machine that manipulates data according to a set of instructions.Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century . These were the size of a large room, consuming as...

An emulator in computer sciences duplicates the functions of one system using a different system, so that the second system behaves like the first system...

VM refers to a family of IBM virtual machine operating systems used on IBM System/370, System/390, zSeries, and System z IBM mainframes and compatible systems, including the Hercules emulator for personal computers. The first version, released in 1972, was VM/370, or officially Virtual Machine...

Multiple Virtual Storage, more commonly called MVS, was the most commonly used operating system on the System/370 and System/390 IBM mainframe computers...

POSIX or "Portable Operating System Interface [for Unix"] is the name of a family of related standards specified by the IEEE to define the application programming interface , along with shell and utilities interfaces for software compatible with variants of the Unix operating system, although the...

EROS is an operating system developed by The EROS Group, LLC., the Johns Hopkins University, and the University of Pennsylvania. Features include automatic data and process persistence, some preliminary real-time support, and capability-based security. EROS is purely a research operating system,...

CapROS is an open source operating system. It is a pure capability-based system that features automatic persistence of data and processes, even across system reboots...
