Assignment 2.1 Chapter 5 1-37 odd | | | | * What are the four layers of the TCP/IP model? Application layer, Transport layer, Internet layer, and Network Interface layer. * What are well-known ports? Ports reserved by ICANN (1 – 1023) * Define the purpose of a connection oriented protocol. It establishes a connection, manages the delivery of data, and terminates the connection. * What is the purpose of a sequence number (SEQ=) in TCP data packets? The sequence number is used to keep track of the data packets being transferred from host A to host B. * Describe how a TCP connection is terminated. The Host B sends a FIN (finish) packet to host A. Host A then sends an ACK packet acknowledging the reception of the FIN packet. Host A sends a FIN packet, then Host B responds with an ACK packet. * What is the purpose of the Internet layer in the TCP/IP protocol suite? Defines the protocol used for addressing and routing data packets. * What is the purpose of an ARP reply? The protocol that contains the hardware address for the destination host. * When is IGMP used? It’s used to control the flow of data in the network, for reporting errors, and for preforming diagnostics. * Convert the following 8-bit binary number to decimal: 10010011. 147. * Convert the following 8-bit number to decimal: 1111100. 252. * Convert the number 192 to its binary equivalent. 11000000. * Convert the number 96 to its binary equivalent. 01100000. * Convert 0x5AF3 to binary. Use Table 5-5. 0101101011110010. * What is the IP address range for class C addresses? 192.0.0.0 to 223.255.255.255 * How many bits are in an IPv4 address? How many octets? 32 bits within 4 octets. * The IP address 192.168.12.2 is an example of what format? Dotted Decimal Format. * How many network and host bits are in a class C network
