Extended search being performed may take a significant time so a forking proxy must send a 100 Trying response. [1] : §21.1.1. 180 Ringing. Destination user agent received INVITE, and is alerting user of call. [1] : §21.1.2. 181 Call is Being Forwarded. Servers can optionally send this response to indicate a call is being forwarded.

Key Code Qualifier. Key Code Qualifier is an error-code returned by a SCSI device. When a SCSI target device returns a check condition in response to a command, the initiator usually then issues a SCSI Request Sense command. This process is part of a SCSI protocol called Contingent Allegiance Condition. The target will respond to the Request ...
The first element of a CIRC decoder is a relatively weak inner (32,28) Reed–Solomon code, shortened from a (255,251) code with 8-bit symbols. This code can correct up to 2 byte errors per 32-byte block. More importantly, it flags as erasures any uncorrectable blocks, i.e., blocks with more than 2 byte errors.
The term "drive-by download" usually refers to a download which was authorized by a user without understanding what is being downloaded, such as in the case of a Trojan virus. In other cases, the term may simply refer to a download which occurs without a user's knowledge. Common types of files distributed in drive-by download attacks include ...
In computing, a page fault (sometimes called PF or hard fault) [a] is an exception that the memory management unit (MMU) raises when a process accesses a memory page without proper preparations. Accessing the page requires a mapping to be added to the process's virtual address space. Besides, the actual page contents may need to be loaded from ...

The requested action is being initiated; expect another reply before proceeding with a new command.
In coding theory, the repetition code is one of the most basic linear error-correcting codes. In order to transmit a message over a noisy channel that may corrupt the transmission in a few places, the idea of the repetition code is to just repeat the message several times. The hope is that the channel corrupts only a minority of these repetitions.
