What does Arq mean before a name in Mexico?
It means arquitecto, or architect in Spanish.
Is arq ok in scrabble?
No. Arq is not a legal Scrabble word.
Differences between go back n arq and selective repeat arq protocol?
1.Selective repeat ARQ is efficient for noisy links and Go Back N ARQ is inefficient for noisy link. 2.Selective Repeat ARQ is complicated whether Go Back N ARQ is less complicated than Selective repeat ARQ. 3.in Sender and receiver Window Size is 2^(m-1) and in Go Back N ARQ Sender Window Size is 2^(m)-1 and receiver window size is 1.
When Using 5-bit sequence numbers what is the maximum size of the send and receive windows for each of the following protocols stop and wait arq go-back n arq selective repeat arq?
Protocols Send window size Receive window sizeStop‐and‐Wait ARQ 1 1Go‐Back‐N ARQ 32 - 1 = 31 1Selective‐Repeat ARQ 32/2 = 16 32/2 = 16

What does the number on a NAK frame mean for Selective Repeat ARQ?
Receiver asking for missing frame number to be resend
Discuss about the difference between go-back-n ARQ and Selective Repeat ARQ?
Go-Back-N ARQRetransmission begins with the last unacknowledged frame even if subsequent frames have arrived correctly .duplicate frames are discarded.Go-back-n ARQ -- Receiver must get Frames in correct orderSelective Repeat ARQOnly the unacknowledged frame is retransmitted.It may be (slightly) more efficient than Go-back-n ARQ, but also much more complicated.Selective repeat ARQ -- correctly-received out-of-order Frames are stored at Receiver until they can be re-assembled into correct orderHamida Almangush

What is error control in networking?
An error-detection code by itself does not control errors, but it can be used to request repeated transmission of errored code words until they are received error-free. This technique is called ARQ. In terms of error performance, ARQ outperforms forward error correction (FEC) because code words always are delivered error-free (provided the error-detection code doesn't fail). However, this performance does not come free of charge - we pay for it with decreased throughput. The chief advantage of ARQ is that error detection requires simpler decoding than error correction. ARQ also is adaptive because it only re-transmits information when errors occur. On the other hand, ARQ schemes require a feedback path that may not be available.
Why it is not necessary to have rej0 and rej1 for stop-and-wait arq?
The purpose of REJ (reject) is to indicate a negative acknowledgement for a frame. This is not needed for Stop-and-Wait ARQ because of the way it is designed... If there is a damaged frame, a timer expires after a period of time and then the frame is resent. If there is a damaged acknowledgment, then the frame is resent after a timeout as well. So to summarize, REJ0 and REJ1 are not required because stop-and-wait ARQ uses timers which eliminates the need for REJ0 and REJ1.
What is ARQ in computer networking?
Automatic Repeat reQuest, an errot control mechanism for data transmission.See the Related Link.
Explain the reasons for moving from stop and wait arq to the go back-n arq protocol?
In Stop and Wait ARQ, the sender needs to stop and wait for acknowledgement to each data frame that it has sent to the receiver When the sender sends a data frame to the receiver it starts timer. If the frame that the sender has sent is damaged. The receiver will not get any frame received So, it doesn't send any acknowledgement to that frame. By then, if the timer expires, the sender will resend that frame. In this protocol, sender has to set the timer every time it sends a frame. How ever in Go Back n ARQ, the sender need not wait for the acknowledgement of the first frame it has sent. Sender can send multiple frames while waiting for acknowledgement. Several frames can be sent before we receive news about the previous frames. This s aves time. A task has begun before the previous task has ended. Here the task is sending all the subsequent frames after sending the first frame before getting the acknowledgement for the first frame. so eventually multiple frames are to be put in transition while waiting for acknowledgement. This is called Pipelining. this improves the efficiency of the transmission.
