Borland Sidekick was a personal information manager (PIM) launched by American software company Borland in 1984 under Philippe Kahn's leadership. It was an early and popular terminate-and-stay-resident program (TSR) for MS-DOS which enabled computer users to activate the program using a hot key combination (by default: Ctrl-Alt) while working in other programs.
A terminate-and-stay-resident program (commonly TSR) is a computer program running under DOS that uses a system call to return control to DOS as though it has finished, but remains in computer memory so it can be reactivated later. [1] This technique partially overcame DOS's limitation of executing only one program, or task, at a time.
An analogy to mind uploading is to copy the information state of a computer program from the memory of the computer on which it is executing to another computer and then continue its execution on the second computer. The second computer may perhaps have different hardware architecture, but it emulates the hardware of the first computer.
SoftRAM was designed for use with Windows 3.1.It was launched in March 1995 and sold more than 100,000 copies. [2]Most out-of-memory errors in Windows 3.x were caused by the first megabyte of memory in a computer, the conventional memory, becoming full.
For example, a watchdog timer can terminate a process that remains idle beyond a specified time limit. [3] [4] Database Transactions: In database management, aborting (often termed ‘rolling back’) a transaction is crucial for maintaining data integrity. If a transaction cannot be completed successfully, aborting it returns the database to ...
Process creation in Windows is done through the CreateProcessA() system call. A new process runs in the security context of the calling process, but otherwise runs independently of the calling process. Methods exist to alter the security context in which a new processes runs. New processes are assigned identifiers by which they can be accessed.
A computer with a von Neumann architecture stores program data and instruction data in the same memory, while a computer with a Harvard architecture has separate memories for storing program and data. [5] [6] However, the term stored-program computer is sometimes used as a synonym for the von Neumann architecture.
On many computer operating systems, a computer process terminates its execution by making an exit system call. More generally, an exit in a multithreading environment means that a thread of execution has stopped running. For resource management, the operating system reclaims resources (memory, files, etc.) that were used by the process.
