A+ Certification
The '''A+ certification''' demonstrates competency as a computer technician. CompTIA A+ certification is a vendor neutral certification.
It requires two tests to be passed: the [[wikipedia:A+ Essentials|A+ Essentials]] exam and a choice of one of three elective exams. CompTIA is vendor neutral but leans towards Microsoft operating systems, although some Apple questions do appear on newer exams.

# Win.com will start KERNEL32.DLL, KERNEL386.EXE, GDI.EXE, and  GDI32.EXE.  The Kernel files are the operating systems.  The GDI files are responsible for the graphical functions and display.
# The Kernel files will load the Explorer user interface, which includes the Desktop, Taskbar, and Start Menu.
# The Kernel will then process anything in the Startup folder and restore network connections.
# The user can now interact with the operating system.



  === WIN2000/NT/XP BOOT PROCESS ===

# BIOS runs POST.
# Computer finds the boot device and loads Master Boot Record (MBR) into RAM.
# MBR looks for the active partition on the boot device and loads the boot sector.
# The boot sector in turn starts the Ntldr file which will load the operating system.
# Ntldr configures the computer’s processor to recognize all of the memory.
# Ntldr will start the file system, and the operating system will load, whether it is FAT or NTFS.
