It was adopted for use with computing, and it refers to any situation in which something is dealt with on a "first-in, first-out" basis. In a file and print context, a queue is an imaginary line that print jobs wait in to ge t serviced. Q I can't print from one particular station, and I've traced it down to something to do with the server, because the queue file is not the same on the server as it is on the workstation. What's the next step in tracking this down? A If other folks are successfully printing to this server queue, it might be something to do with the workstation. However, this workstation might be on a different network segment than the others that print successfully. Can you move the workstation? That might point to a failing router or switch port. Q Is there any way to clear somebody's locks on a file without disconnecting them from the server? A NT can clear someone's lock on a file; Novell cannot. To clear someone's lock on a file residing on a Novell server, you've either got to call the user and ask him or her to stop using the file, or you need to clear the network connection from the server. Q Is there a Telnet-type tool for UDP to see if a UDP socket is listening? A To know whether a connectionless socket is listening, you've got to get a response. To get a response, you need to send it the correct kind of "note." So no. The only tool you can use to remotely see if a UDP server is up is the client. Quiz 1.
