10 packets can sender transmit before it starts recieving acknowledgements back .

In telecommunications and computer networking, a network packet is a structured unit of data delivered via a packet-switched network. A packet is made up of control information and user data, often known as the payload. Control data provides information needed to deliver the payload.

packet length = 10k bits

                        =  10 * [tex]2^{10}[/tex] bits

band width = 10 mbps = 10  * [tex]10^{6}[/tex] sec

transmission time = L / b.w. = ( 10 *2^10 )/ (10 * 10^6) = 0.001024 sec.

for every 0.001024 sec one packet transmit to reciever from sender .

number of packets sent in 10 ms = (10 * 10^-3) / 0.001024 = 9.76 = 10(approx.)
