Test III. Matching Type. 1. Network ID a. A protocol is a set of rules that govern data communications. It represents an agreement between the communicating devices. 2. Class B b. a networks range from 128 to 191. 3. Logical addressing c. A core function of IP is to provide logical addressing for hosts. 4. IP d. identifies which network a host belongs to. 5. Class D e. A link is a communications pathway that transfers data from one device to another. 6. Routing f. determines the best path to a particular destination network, and then routes data accordingly. 7. IP Address g.It provide no mechanism to create boundaries between networks. 8. Class A h. provides a unique address that identifies both the host, and the network that host exists on. 9. TCP i. is the most widely-used logical address, and is the backbone protocol of the Internet. 10. Class C j. it is a Part of an IP address identifies the network. 11. Host ID k. networks are reserved for multicast traffic. 12. Hardware Addressing l. is used to uniquely identify a host within a local network. 13. MAC address m. Backbone of MAN is high-capacity and high-speed fiber optics. 14. IPv4 Addressing n. uniquely identifies the host on that network. 15. Subnet mask o. a networks range from 1 to 127 16.
