  2. Performance Monitor - Wikipedia

    en.wikipedia.org/wiki/Performance_Monitor

    This type of application may be used to determine the cause of problems on a local or remote computer by measuring performance of hardware, software services, and applications. The program can define thresholds for alerts and automatic actions, generate reports, and view past performance data. [1] [2] [3] In Windows 9x, System Monitor is not ...

    A system monitor displaying system resources usage. A system monitor is a hardware or software component used to monitor system resources and performance in a computer system. [1] Among the management issues regarding use of system monitoring tools are resource usage and privacy. Monitoring can track both input and output values and events of ...

  4. Page fault - Wikipedia

    en.wikipedia.org/wiki/Page_fault

    In computing, a page fault is an exception that the memory management unit (MMU) raises when a process accesses a memory page without proper preparations. Accessing the page requires a mapping to be added to the process's virtual address space.

    30-pin SIMM, 256 KB capacity Two 30-pin SIMM slots on an IBM PS/2 Model 50 motherboard. Standard sizes: 256 KB, 1 MB, 4 MB, 16 MB. 30-pin SIMMs have 12 address lines, which can provide a total of 24 address bits. With an 8-bit data width, this leads to an absolute maximum capacity of 16 MB for both parity and non-parity modules (the additional redundancy-bit chip usually doe

  7. Serial presence detect - Wikipedia

    en.wikipedia.org/wiki/Serial_presence_detect

    In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module. Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.

  8. SoftRAM - Wikipedia

    en.wikipedia.org/wiki/SoftRAM

    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.

  9. Dual-ported RAM - Wikipedia

    en.wikipedia.org/wiki/Dual-ported_RAM

    Dual-ported RAM (DPRAM), also called dual-port RAM, is a type of random-access memory (RAM) that can be accessed via two different buses.. A simple dual-port RAM may allow only read access through one of the ports and write access through the other, in which case the same memory location cannot be accessed simultaneously through the ports since a write operation modifies the data and therefore ...
