Ace Test Series: Digital Logic - Decoder
A $3$ line to $8$ line Decoder is used to implement a $3$-variable Boolean function as shown in figure. The simplified form of output $Y$ is. $\bar{X}Y + \bar{Y}Z + XY\bar{Z}$ $\bar{X}Z +\bar{Y}Z + XYZ$ $X\bar{Y} + X\bar{Z} +\bar{X}YZ$ $X\bar{Y} + X\bar{Z} + \bar{X}Y\bar{Z}$

Congest oSlow start
What is the effective throughput for transferring a 1600 KB file when TCP using slow start congestion control technique. Given round trip time 20 ms and Maximum segment size 800 bytes. Assume there are no packet losses, unlimited bandwidth, and receiver window size. Assume slow start begins initially with a congestion window size of 1. Answer given = 8MBPS.
