The Memory Address Register
In a computer, the memory address register (MAR) is the CPU register that either stores the memory address from which data will be fetched to the CPU registers, or the address to which data will be sent and stored via system bus.

See lessFragmentation of the file system
File fragmentation occurs when a file is stored in non-contiguous sectors on a hard drive, causing it to take longer to open and decrease overall performance. It can occur when a file is saved, deleted, and re-saved over time, as well as if there is insufficient free space on the hard drive.

See lessIn virtual memory systems, Dynamic address translation
Dynamic address translation, or DAT, is the process of translating a virtual address during a storage reference into the corresponding real address. If the virtual address is already in central storage, the DAT process may be accelerated through the use of a translation lookaside buffer.

Thrashing can be avoided if the pages, belonging to the working set of the programs, are in the main memory. Eliminating one or more running apps is a temporary fix for thrashing. Increased main memory space is one of the suggested solutions to stop thrashing.
