A server for the LPD protocol listens for requests on TCP port 515. [1] A request begins with a byte containing the request code, followed by the arguments to the request, and is terminated by an ASCII LF character. An LPD printer is identified by the IP address of the server machine and the queue name on that machine. Many different queue ...

A helper application (cups-lpd) converts Line Printer Daemon protocol (LPD) requests to IPP. The scheduler also provides a web-based interface for managing print jobs, the configuration of the server, and for documentation about CUPS itself. [14] An authorization module controls which IPP and HTTP messages can pass through the system. [17]

The iOS mobile operating system developed by Apple has had a wide range of bugs and security issues discovered throughout its lifespan, including security exploits discovered in most versions of the operating system related to the practice of jailbreaking (to remove Apple's software restrictions), bypassing the user's lock screen (known as lock screen bypasses), issues relating to battery ...
An application layer is an abstraction layer that specifies the shared communication protocols and interface methods used by hosts in a communications network. [1] An application layer abstraction is specified in both the Internet Protocol Suite (TCP/IP) and the OSI model. [2]
