  2. Memory overcommitment - Wikipedia

    en.wikipedia.org/wiki/Memory_overcommitment

    Memory swapping is then used to handle spikes in memory usage. The disadvantage of this approach is that memory swap files are slower to read from than 'actual' memory, which can lead to performance drops. [2] Another disadvantage is that, when running out of real memory, the system is relying on the applications to not use the additional ...

    en.wikipedia.org/wiki/Software_bloat

    Microsoft Windows has also been criticized as being bloated – with reference to Windows Vista and discussing the new, greatly slimmed down Windows 7 core components, Microsoft engineer Eric Traut commented that "This is the core of Windows 7. This is a collection of components that we've taken out.

    Memory leaks: Memory leaks occur when a program fails to release memory that it no longer needs, leading to a gradual depletion of available RAM. Over time, memory leaks can cause your computer to ...

  5. Thrashing (computer science) - Wikipedia

    en.wikipedia.org/wiki/Thrashing_(computer_science)

    Thrashing is when the CPU performs 'productive' work less and 'swapping' work more. The overall memory access time may increase since the higher level memory is only as fast as the next lower level in the memory hierarchy. [2] The CPU is busy swapping pages so much that it cannot respond to users' programs and interrupts as much as required.

    Windows 11 is the latest major release of the Windows NT operating system and the successor of Windows 10. Some features of the operating system were removed in comparison to Windows 10, and further changes in older features have occurred within subsequent feature updates to Windows 11. Following is a list of these.

    en.wikipedia.org/wiki/Direct_memory_access

    Due to their lagging performance (1.6 MB/s maximum 8-bit transfer capability at 5 MHz, [4] but no more than 0.9 MB/s in the PC/XT and 1.6 MB/s for 16-bit transfers in the AT due to ISA bus overheads and other interference such as memory refresh interruptions [1]) and unavailability of any speed grades that would allow installation of direct ...

  8. CPU cache - Wikipedia

    en.wikipedia.org/wiki/CPU_cache

    In the early days of microcomputer technology, memory access was only slightly slower than register access. But since the 1980s [62] the performance gap between processor and memory has been growing. Microprocessors have advanced much faster than memory, especially in terms of their operating frequency, so memory became a performance bottleneck ...

    en.wikipedia.org/wiki/Windows_11

    Windows 11 is the first major version of Windows NT without a companion mobile version following the discontinuation of Windows Phone with Windows 10 Mobile. Windows 11 features major changes to the Windows shell influenced by the canceled Windows 10X, including a redesigned Start menu, the replacement of its "live tiles" with a separate ...
