  2. Booting process of Linux - Wikipedia

    en.wikipedia.org/wiki/Booting_process_of_Linux

    The Linux kernel handles all operating system processes, such as memory management, task scheduling, I/O, interprocess communication, and overall system control. This is loaded in two stages – in the first stage, the kernel (as a compressed image file) is loaded into memory and decompressed, and a few fundamental functions are set up such as ...

  3. Database dump - Wikipedia

    en.wikipedia.org/wiki/Database_dump

    A database dump contains a record of the table structure and/or the data from a database and is usually in the form of a list of SQL statements ("SQL dump"). A database dump is most often used for backing up a database so that its contents can be restored in the event of data loss.

  4. dump (Unix) - Wikipedia

    en.wikipedia.org/wiki/Dump_(Unix)

    The dump command is a program on Unix and Unix-like operating systems used to back up file systems. It operates on blocks, below filesystem abstractions such as files and directories. Dump can back up a file system to a tape or another disk. It is often used across a network by piping its output through bzip2 then SSH.

    However, new software added to the system may require changes to existing files that risk producing an unbootable system. BSD init was, prior to 4.3BSD, the same as Research UNIX's init; [ 4 ] [ 5 ] in 4.3BSD , it added support for running a windowing system such as X on graphical terminals under the control of /etc/ttys .

  7. Initial ramdisk - Wikipedia

    en.wikipedia.org/wiki/Initial_ramdisk

    This leaves the initial root file system at a mount point (such as /initrd) where normal boot scripts can later unmount it to free up memory held by the initrd. On an initramfs, the initial root file system cannot be rotated away. [10] Instead, it is simply emptied and the final root file system mounted over the top.

  8. systemd - Wikipedia

    en.wikipedia.org/wiki/Systemd

    systemd is a software suite that provides an array of system components for Linux [7] operating systems. The main aim is to unify service configuration and behavior across Linux distributions. [8] Its primary component is a "system and service manager" — an init system used to bootstrap user space and manage user processes.

  9. procfs - Wikipedia

    en.wikipedia.org/wiki/Procfs

    The proc filesystem (procfs) is a special filesystem in Unix-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory.
