GATE CSE 2015 Set 3 | Question: 28
Consider a network connecting two systems located $8000$ $\text{Km}$ apart. The bandwidth of the network is $500 \times 10^6$ $\text{bits}$ per second. The propagation speed of the media is $4 \times 10^6$ $\text{meters}$ per ... . Assume that processing delays at nodes are negligible. Then, the minimum size in bits of the sequence number field has to be ______.

GATE IT 2007 | Question: 64
A broadcast channel has $10$ nodes and total capacity of $10$ Mbps. It uses polling for medium access. Once a node finishes transmission, there is a polling delay of $80$ μs to poll the next node. Whenever a node is polled, it is allowed to transmit a maximum of $1000$ bytes. The maximum throughput of the broadcast channel is: $1$ Mbps $100/11$ Mbps $10$ Mbps $100$ Mbps

GATE IT 2007 | Question: 62
Let us consider a statistical time division multiplexing of packets. The number of sources is $10$. In a time unit, a source transmits a packet of $1000$ bits. The number of sources sending data for the first $20$ ... unit. Then the average number of backlogged of packets per time unit during the given period is $5$ $4.45$ $3.45$ $0$

Tanenbaum -A 1-km-long, 10-Mbps CSMA/CD LAN
A 1-km-long, 10-Mbps CSMA/CD LAN (not 802.3) has a propagation speed of 200 m/μsec. Repeaters are not allowed in this system. Data frames are 256 bits long, including 32 bits of header, checksum, and other overhead. The ... frame. What is the effective data rate, excluding overhead, assuming that there are no collisions? ans=3.8 mbps please explain??
