Presentation slides are here

  • Understand the Windows permission system.
  • Manage NTFS permissions.
  • Distinguish between the three types of sharing.
  • Manage share permissions.
  • Understand the Windows print architecture.

access control entry (ACE) An individual permission assignment in an access control list, consisting of a security principal and the specific permissions assigned to that security principal. 

access control list (ACL) An attribute of a Windows operating system element, such as a file, a printer, or a registry entry, which consists of a collection of individual permission assignments, in the form of access control entries (ACEs).

effective permissions The combination of permissions affecting a security principal’s access to a protected resource, whether derived from explicit permission assignments, permission inheritance, or group memberships. 

NTFS permissions A system by which administrators control access to the files and folders stored on disk volumes formatted with the NTFS file system. To access a file, whether on the local system or over a network, a user must have the appropriate NTFS permissions.

print device A type of hardware device, connected to a computer or a network, which produces hard copy documents on paper or other print media.

printer The software interface through which a computer communicates with a print device. Windows 7 supports numerous interfaces, including parallel (LPT), serial (COM), USB, IEEE 1394, Infrared Data Access (IrDA), Bluetooth, and TCP/IP ports, as well as network printing services such as lpr, and Internet Printing Protocol (IPP).

printer control language (PCL) A communications protocol that computers and print devices use to exchange information about print jobs and device status. Each printer is associated with a printer driver that takes the commands generated by an application and converts them into the printer’s PCL.

printer driver A device driver that converts the print jobs generated by applications into an appropriate string of commands for a specific print device. Printer drivers are designed for specific print device and provide applications with access to all of the print device’s features.

print server A computer (or standalone device) that receives print jobs from clients and sends them to print d
evices that are either locally attached or connected to the network.

security principal The name of the user, group, or computer being granted permissions.
