IEEE 802.1d specification, defines _________ criteria for a transparent bridges. a. two b. three c. four d. none of the above

HDLC (High-level Data Link Control) is a group of protocols or rules for transmitting data between network end points. In more technical terms, HDLC is a bit-oriented, synchronous data link layer protocol created by ISO. In your report discuss the following: introduction about HDLC, types of stations, mode operation, frame formats, HDLC flow control and OSI layer for HDLC.

“The lack of support for emerging networking paradigms is a problem that cannot be tackled easily by employing existing techniques”.(extracted from p.269 of the prescribed textbook)Search and study one Next‐generation Internet Architecture and then critically discuss how thisarchitecture addresses the shortcomings in the Internet architecture. Ensure that the discussion follows the following format:• Introduction;• What is Internet architecture?• Describe the Next‐generation Internet Architecture you have selected.• Can Next‐generation Internet Architecture address the shortcomings in the Internetarchitecture?

Your Task Your company was assigned the network ID 192.32.0.0 and the network block of /16 (that is 192.32.0.0/16 in CIDR notation). This was previously used by only one department, A. However, over the years, your company grew and three other departments emerged for a total of four departments. As the network engineer for your organization, you have been tasked with creating subnets for all four departments, A, B, C, D and assigning IP addresses to each department as follows: Department A - 3500 IP addresses, Department B - 2000 IP addresses; Department C- 400O IP addresses and Department D- 7500 IP addresses. Assume that a large number of consecutive IP addresses are available starting from 192.32.0.0, and assign each department the required IP addresses for conducting their respective business functions. For each department, specify the first IP address assigned, the last IP address assigned and the corresponding mask, using w.x.y.z/s. Company Addresses Requested Starting Address…

Please, I need the final solution as soon as possible, I do not need any explanation or explanation

Question 2: What best describe the following : A collection of computer networks interconnected together__________________ A network in which small chunks of data are passed through the network from node to node, and at each node the entire data chunk is received, stored briefly, and then transmitted to the next node IS A PACKET SWITCHING NEWT WORK This protocol model was developed by the International Organization for Standardization as a model for a computer protocol architecture and as a framework for developing protocol standards. ________________________ A device is used to connect different types of networks. __________________________

Describe hidden node problem in wireless local area networks(WLANs) , Which mechanism is employed by IEEE 802.11(WLAN) to eliminate hidden node problem.

The table below belongs to the bridge in Figure 4 MAC Address Interface No Date/Time 65-FD-B7-81-39-C5 1 10:15 9C-FA-B2-B8-71-50 3 10:16 Within collision domain of Department of Electric and Electronics Engineering  in Figure 4, there exists a host (Host#1) with 9C-FA-B9-BB-71-50 MAC address. There is another host (Host#2) with 65-FE-B8-99-39-D5 MAC address within the collision domain of Food Engineering in Figure 4. Host #1 sends a frame to Host #2. How will the bridge handle this transmission? What will it do? Explain the transmission step-by-step in reason until the frame is transmitted to the destination host.
