Named Pipe
A pipe is a simple Windows data transfer mechanism that works, well, pretty much like a pipe: You stuff things in one end and the things come out the other end. You can establish a pipe both locally and to a remote machine.  One machine must have created the pipe (the server), and another machine that wants to use the pipe (the client) must know both the name of the server machine and the name of the pipe on the server machine.

Once the client and the server have agreed to communicate using a named pipe, they can stuff data into the pipe and read the data from the other side of the pipe.  The Software Update Wizard service creates the pipe, and the Software Update Wizard DLL component writes to the pipe.  The pipe implementation is one way only - incoming to the service.

Script
In the context of the Software Update Wizard, a script is a simple text file which is uploaded to your web server and contains a series of script sections, each of which contains all the information (keyword lines) needed to process the update of a single file on a client computer.  See also: Section, Keyword Lines
 
Section
A series of keyword lines within a script.
 
Service application
A Windows Service application is a type of executable that gets special treatment from the operating system.  A service runs whenever the computer is running the operating system. It does not require a user to be logged on.  It runs within the security context of the operating system rather than any logged on user, and therefore has the security rights to update files which the logged on user cannot.

URL
