Which of the following is/are stateless transport layer protocol?

In a network, on an average 60,000 frames pass every two minutes. The bandwidth of the network is 20 Mbps. If each frame is carrying 5,000 bits. What is the throughput of this network in Mbps? (Answer up to 1 decimal place)

Match List I and List II

Choose the correct option from those given below:

The baud rate at the time Manchester encoding is 1.5 × 10⁷ b/s.  Bit rate in the ethernet is k × 10⁶ b/s. What is the value of k?

Consider two systems are connected with LAN cable. The length of the cable is 3 kilometers and the data transmitted at a rate of  30 MB/s. The signal speed in the cable is 2.5 × 108 m/s. What is the minimum frame size in bits in the CSMA/CD network?

Consider a LAN with 3 nodes N1, N2 and N3. Time is divided into fixed-size slots, and a node can begin its transmission only at the beginning of a slot. A collision is said to have occurred if more than one node transmits in the same slot. The probabilities of generation of a frame in a time slot by N1, N2 and N3 are 0.2, 0.4, and 0.6, respectively. The probability of sending a frame in the first slot without any collision by any of these three stations is \(\frac{x}{{1000}}\;.\;\) What is the value of x?

Which of the following is/are false about different layers of the OSI model?

A. Fragmentation of datagram is performed at Transport layer

B. Data compression is performed at the Session layer

C. Dialog control is done is at the Application layer.

Choose the most appropriate option

Two hosts are connected by a single direct link. Link transfer the data at a rate of 10⁷ bits/seconds. The distance between the two host is 5000 km and the propagation speed along the link is 2 × 10⁵ kilometer per second. One host is sending a data of 10,000 bytes in a single packet to another host. Let T_t be the transmission delay and T_P be the propagation delay. The difference between the propagation delay and the transmission delay in millisecond is _____.

II. 2A : 1F : 41 : 4C : 11:19

III. FF : FF : FF : FF : FF : FF

IV. C9 : EA : B2 : 1D : 64 : 15
