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 ...

Linux systems have traditionally run with a single address space that is shared by user and kernel space. That changed with the advent of the Meltdown vulnerability, which forced the merging of kernel ...

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 ...

Speculative-execution vulnerabilities come about when the CPU can be fooled into accessing arbitrary memory in a speculative mode, bypassing checks that (presumably) exist in the code to prevent such ...

“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 ...

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 ...

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 ...
