Problem 2: Acronym Match                                                                         (6 Points)

For each of the concepts given below, list which of the following acronyms apply:

802.3, 802.11, ARP, BGP, CIDR, CRC, CSMA/CD, DNS, FDMA, FTP, HTTP, IPv4, IPv6, ICMP, LAN, MTU, NIC, OSPF, RFC, RTT, SMTP, TCP, TDMA, TLD, TTL, UDP, URL

Not all acronyms are used. Unless otherwise stated, there is one acronym per concept.

1. A way of interpreting IP addresses as having an initial (variable-length) network prefix, plus the remaining bits identifying a host within that network: _____________
2. The IEEE standardization of Ethernet Medium Access: _____________
3. 2 types of layer-4 protocols: _____________
4. A term referring to a host’s network adaptor; Hardware device that handles an interface to a computer network and allows a network-capable device to access that network: _____________.
5. The largest sized packet that can be sent across a link (or a network path) without requiring fragmentation: _____________.
6. The style of MAC (Media Access Control) protocol used by Ethernet: _____________
7. A scheme for computing a checksum value over a block of data in order to detect bit errors: _____________
8. The time it takes to send a packet to a destination and hear a response back from it: _____________
9. A counter in the IP header that is decreased at each hop; if it reaches 0, the packet is discarded (also refers to how long to keep a DNS response in a local cache): ________
10. A way of sharing a link’s capacity among a group of senders in which each sender is assigned its own frequency to use when transmitting, which it can use to transmit whenever it pleases: _____________
