Address space is the amount of memory allocated for all possible addresses for a computational entity -- for example, a device, a file, a server or a networked computer. The system provides each ...

The Number Resource Organization warns that less than 10 percent of the IPv4 address space remains; it’s time to start adopting IPv6. The warning comes after APNIC, the registry that hands out IP ...

“The Internet has grown beyond anyone’s expectations. Sustained exponential growth continues to introduce new challenges. One challenge is a concern within the community that globally unique address ...

Prelink (PDF) is a popular tool used to decrease program load time, shortening system boot time and making applications start faster. Developed by Jakob Jelinek at Red Hat, prelink relocates libraries ...

Mike Rapoport from IBM launched a bid to implement address space isolation in the Linux kernel. Address space isolation emanates from the idea of virtual memory—where the system maps all its hardware ...

Address space layout randomization (ASLR) is a memory-protection process for operating systems (OSes) that guards against buffer-overflow attacks by randomizing the location where system executables ...

The traditional organization of the virtual address space (as seen from user space, on x86 systems) is as shown in the diagram to the right. The very bottom part of the address space is unused; it is ...

Memory (RAM) that is addressed starting with 0, and each subsequent byte is referenced by the next sequential number (1, 2, 3, etc.). A 32-bit computer with a 32-bit address space treats all 4GB of ...

Memory addressing in which each byte is referenced by a base number (the segment) plus an offset. An x86-based PC running in 16-bit mode (Real Mode and Virtual 8086 Mode) uses 64KB segments, and a ...
