File-backed mapping maps an area of the process's virtual memory to files; that is, reading those areas of memory causes the file to be read. It is the default mapping type. Anonymous mapping maps an area of the process's virtual memory not backed by any file, made available via the MAP_ANONYMOUS/MAP_ANON flags.
A memory-mapped file is a segment of virtual memory [1] that has been assigned a direct byte-for-byte correlation with some portion of a file or file-like resource. This resource is typically a file that is physically present on disk, but can also be a device, shared memory object, or other resource that an operating system can reference through a file descriptor.
If a Linux program is to be distributed widely, an LSM file may be created to describe the program, normally in a file called software_package_name.lsm. This file begins with Begin4 and ends with End. It has one field on each line. The field name is separated from the value by a colon (:). Mandatory fields are Title, Version, Entered-date ...
Program database (PDB) is a file format (developed by Microsoft) for storing debugging information about a program (or, commonly, program modules such as a DLL or EXE). PDB files commonly have a .pdb extension. A PDB file is typically created from source files during compilation.
if the file cannot be read, or its Unix file type is undetermined, the file program will indicate that the file was processed but its type was undetermined. file must be able to determine the types directory, FIFO, socket, block special file, and character special file; zero-length files are identified as such
Virtual addresses are used by the program executed by the accessing process, while physical addresses are used by the hardware, or more specifically, by the random-access memory (RAM) subsystem. The page table is a key component of virtual address translation that is necessary to access data in memory.
Most email software and applications have an account settings menu where you'll need to update the IMAP or POP3 settings. When entering your account info, make sure you use your full email address, including @aol.com, and that the SSL encryption is enabled for incoming and outgoing mail.
LibreOffice Base is designed to allow users to easily create, access, modify, and view databases and their data. This is done by providing users with a graphical user interface that allows users to work with four main tools: Tables, queries, forms, and reports. [6] [7] Base includes software wizards to assist users with various aspects of the ...
