Once all the boot and system drivers have been loaded, the kernel starts the session manager (smss.exe), which begins the login process. After the user has successfully logged into the machine, winlogon applies User and Computer Group Policy setting and runs startup programs declared in the Windows Registry and in "Startup" folders.
The second-stage loader (stage2, the /boot/grub/ files) is loaded by the stage1.5 and displays the GRUB startup menu that allows the user to choose an operating system or examine and edit startup parameters. After a menu entry is chosen and optional parameters are given, GRUB loads the linux kernel into memory and passes control to it.
The Process Data Object protocol is used to process real time data among various nodes. You can transfer up to 8 bytes (64 bits) of data per one PDO either from or to the device. One PDO can contain multiple object dictionary entries and the objects within one PDO are configurable using the mapping and parameter object dictionary entries.
As a result, a significant amount of time is spent 'jumping' from file to file and back again multiple times, even though a single access would be more efficient. The prefetcher works by watching what data is accessed during the boot process (including data read from the NTFS Master File Table), and recording a trace file of this activity. The ...
Processes transmit data by calling on the TCP and passing buffers of data as arguments. The TCP packages the data from these buffers into segments and calls on the internet module [e.g. IP] to transmit each segment to the destination TCP. [16] A TCP segment consists of a segment header and a data section.
When a child process is created, it inherits all the environment variables and their values from the parent process. Usually, when a program calls another program, it first creates a child process by forking , then the child adjusts the environment as needed and lastly the child replaces itself with the program to be called.
In computing, start is a command of the IBM OS/2, [1] Microsoft Windows [2] and ReactOS [3] command-line interpreter cmd.exe [4] (and some versions of COMMAND.COM) to start programs or batch files or to open files or directories using the default program. start is not available as a standalone program.
Svchost.exe (Service Host, or SvcHost) is a system process that can host one or more Windows services in the Windows NT family of operating systems. [1] Svchost is essential in the implementation of shared service processes, where a number of services can share a process in order to reduce resource consumption.
