What is produced by the deencapsulation of a frame?
1- Segment
2- Packet
3- Data segment
4- Bits at layer 0
Answer: 2- Packet
Packet is produced by the deencapsulation of a frame
Decapsulation is the process of opening up encapsulated data that are usually sent in the form of packets over a communication network.

What is the PDU at Layer 3 called? A. Data B. Segment C. Packet D. Frame E. Bit
A TCP segment consisting of 1500 bits of data and 160 bits of header is sent to the IP layer, which appends another 160 bits of header. This is then transmitted through two networks, each of which uses a 24-bit packet header. The destination network has a maximum packet size of 600 bits. How many bits, including headers, are delivered to the network layer protocol at the destination?
A TCP segment consisting of 4,256 bits of data and 184 bits of TCP header is sent to the IP layer. The IP layer uses 200 bits of header. The IP datagram is transmitted through two networks each of which uses a 20-bit header. The target network has a maximum packet size of 1,500 bits. How many total bits, including headers, are delivered to the network layer protocol at the destination?
3) [10 marks] Refer to following Figure 2.14 and Figure 16.3. This question is about encapsulation, decapsulation, and protocols. Figure 2.14 illustrates that a TFTP Trivial File Transfer Protocol) packet is encapsulated in a UDP (User Datagram Protocol) segment that in turn is encapsulated in an IP (Internet Protocol) datagram. In Figure 2.14, the length of each row is 32 bits (4 bytes). For example, the length of row "Source Address" is 32 bits long. Figure 16.3 gives the format...
1. Please explain the functionality of Management Frame, Control Frame and Data Frame in 802.11/WiFi. 2. Compare and contrast the IPv4 and IPv6 header fields. Do they have any fields common? 3. Describe fragmentation and reassembly process in IPv6? What happens when a packet bigger than the size a router can process arrives at the router? What is the advantage of eliminating fragmentation and reassembly at the router level in IPv6? 4. What are different mechanisms used for IPv4 and...
3. A data packet containing 18 bits is sent over a noisy communication channel. The probability that the k-th bit is received correctly at the destination is 1 - p, and, therefore, it is erased with probability p. Erasures are independent over time. (a) 1 pt What is the probability that exactly 7 bits are erased from this packet? (b) 1 pt What is the maximum value of p such that the probability that the packet is received correctly (i.e.,...
What is the size of an ARP packet when the protocol is IPv4 and hardware is Ethernet? Ans: Is the size of ARP packet fixed? Explain. Ans: Assume we have an isolated link (not connected to any other link) such as a private network in a company. Do we still need addresses in both network layer and data link layer? Explain. Ans: In a block code, a dataword is 20 bits, the corresponding codeword is 25 bits. What are the...
a tcp segment with 1480 bits of data and 150 bits of header issend to IP add another 150 bits of header, then is transmitted through twos each of which uses 24 bit packet. if the destination node only has maxiumum packet size 800 bits then how many bits including headers are delivered?
(a) A data link with a 1 Gigabits/sec capacity is used to transmit packets made up of 1400 bytes of data and 100 bytes of protocol control information. Each packet is acknowledged by a short frame of size 150 bytes. The propagation speed in the transmission medium is 200,000 km/sec. Consider the buffering and processing time in the nodes to be negligible. A node A communicates with a node B, with a distance between nodes A and B of 16...
help with computer network questions 1. What is the difference between circuit switching and packet switching? 2. What are the different layers in today’s Internet? Why do we create layers? 3. Suppose there is a 10 Mbps microwave link between a geostationary satellite and its base station on Earth. Every minute the satellite takes a digital photo and sends it to the base station. Assume a propagation speed of 2.4 * 10^8 meters/sec. a. What is the propagation delay of...
