True Or False 1. The acronym API in this textbook stands for “Application Programming for Internet. 2. DSL bandwidth is shared. 3. Suppose 10 connections traverse the same link of rate 1 Gbps. Suppose that the client access links all have rate 5 Mbps. Then the maximum throughput for each connection is 100 Mbps.

Suppose you have a class C Network 200.94.115.0. Your task is to design a subnet scheme so that we can create 28 Network segments (subnets) within this Network. Each subnet should support hosts as given below. 2 Network Segment support 30 Hosts 4 Network Segment support 14 Hosts 8 Network Segment support 6 Hosts 14 Network Segment support 2 Hosts
Choose a set of class C, /24 addresses that could be successfully combined into a supernet that supports 3000 hosts.
Specifically why does packet size matter when two applications don't interact well when they use it on the same link in a single queue such as FTP or backup programs, and real-time streaming applications, such as Voice over IP?
60- A network for a local office requires 4 LAN subnets as follows: · Subnet A - North Office with 31 hosts; · Subnet B - East Office with 15 hosts; and · Subnet C - South Office with 7 hosts. · Subnet D – West Office with 4 hosts. Given the IP Address 192.168.15.0 /24 and above described network requirements: 1. Design an optimal address scheme using Variable Length Subnet Mask (VLSM) method; What will be the range of usable (assignable) host addresses in Subnet D? Select one: A. 192.168.15.224 to 192.168.15.255 B. 192.168.15.113 to 192.168.15.118 C. 192.168.15.192 to 192.168.15.254 D. 192.168.15.193 to 192.168.15.240 E. 192.168.15.192 to 192.168.15.239
Compare and contrast SMTP and HTTP, two widely used application protocols.Explain what "HTTP" means and how it works.Could you tell me what port it uses for connections?The abbreviations for "Transmission Control Protocol" and "User Datagram Protocol" are "TCP" and "UDP," respectively. To what extent do these scenarios have common variables?Can you describe the many kinds of networks that exist? Describe them quickly.
A connectionless protocol, such as Ethernet, defines the route of a packet through source and destination addresses. However, a connection-oriented protocol, such as ATM, defines the route of a cell through virtual connection identifiers (VPIs and VCIs). Could you explain this statement?
a) For the given network diagram, suppose an application running on Host 1 transmits a packet towards application running on Host 2. Graphically represent the process of packet encapsulation and de-capsulation along the path from Host 1 to Host 2.b) Both Layer-2 Switch and Router are used to forward network traffic from one interface to another. How are they different in terms of functionality?
Consider a short, 10-meter link, over which a sender can transmit at a rate of 150 bits/sec in both directions. Suppose that packets containing data are 100,000 bits long, and packets containing only control (e.g., ACK or handshaking) are 200 bits long. Assume that N parallel connections each get 1/N of the link bandwidth. Now consider the HTTP protocol, and suppose that each downloaded object is 100 Kbits long, and that the initial downloaded object contains 10 referenced objects from the same sender. Would parallel downloads via parallel instances of non-persistent HTTP make sense in this case? Now consider persistent HTTP. Do you expect significant gains over the non-persistent case?
