According to me solution:
Q.1
total chanel * cahanel capcty = data rate
i.e
total chanel = 50
chanel capcty = 64kbps
50*64kbps= 3200
ye confusion hy k mbps men cnvrt krny k liey 1024 se divid krain gy ya 1000 se lkn jo file men ne sbmit ki hy us men men ne 1000 se divid kia hy
so
3200/1000 = 3.2mbps
according to data rate hmen T ya E lines ko select krna hy hm 1 se ziada lines b use kr skty hen ta k wastage kam se km ho
i.e
data rate=32mbps
if we combine 2 E-1 lines we can get the data rate 4.096mbps agr hm isy use krain to hmra wastag  hoga 0.896
lkn agr ham koi r conbination bnain to phir hmari wastag ziada ho gi
isis trha baqi ka q b solv krain
Q.2
yahn hmen (CRC) ka proces btana hy. hmen Polynomial dia gya hy us se ham divisor nikalain gy r jitni bits divisor ki hon gi us se 1 bit kam 0's ham real data ka sath atach kr k usy binry division use krty hwy devide krain gy jo remainder ho ga woh hmara CRC ho ga usy ham real data k sath atach kr k send kr dain gy reciver phir uski division kry ga r agr remainder 0 ho to woh data accept kr lay ga warna wapis snd kr day ga yahan q k hmara data without error recive ho gya hy to reciver sidee py hmara remainder 0 hna chahey
