Computer Networking Fundamentals Chapter 2 Pdf Domain Name System Each device on an ip network requires 3 different pieces of information in order to correctly communicate with other devices on the network: an ip address, a subnet mask, and a broadcast address. Network devices why use hubs a hub? pcs on a network communicate through a network interface card (nic) with a hub, all pcs communicate with each other through a central location, where all the pc cables come together.
Networking Fundamentals Pdf Computer Network Router Computing To send information over the internet, a computer packs data into internet protocol (ip) packets and labels them with the correct address. they are then sent across a packet switched interconnected network. the term telecommunication means communication at a distance. Ip addressing addressing domain names: “radford.edu” ip addresses: iii.jjj.kkk.lll, dotted decimal example: radford university has a computer (somewhere) with ip address 137.45.192.36 mac (hardware) address hexadecimal digits separated by colons or dash. example: 00 06 6b ff 0a b4 specific .vs. broadcast (ff ff ff ff ff ff) addresses. Every host must have a unique ip address. ip addresses are assigned by icann. (internet corporation for assigned names and numbers). an ip address such as 176.10.0.0 that has all binary 0s in the host bit positions is reserved for the network address. Computer networks and internets: an overview of concepts, terminology, and technologies that form the basis for digital communication in individual networks and the global internet.

Ip routing module determines best route (direct on interface 128.192.1.250) and passes ip datagram (after decrementing ttl) to dl module along with ip delivery address (128.192.1.9). Chapter 5: implementing tcp ip in the command line this chapter covers understand ing tcp ip tools such as ping, tracert, pathping, telnet, ipconfig, netstat, reserved address ranges for local use (including local loopback ip), protocols as well as discussing using a routers routing table memory. A link layer protocol to map ipv4 address to mac address in the same subnet each host has an arp table in its memory (arp a). a router has an arp table for each of its interfaces. the table map mac addresses to ip addresses. when sending a packet to an ip address, a system will consult its arp table first. Every ip address must be accompanied by a subnet mask. by now you should be able to look at an ip address and tell what class it is. unfortunately your computer doesn’t think that way. for your computer to determine the network and subnet portion of an ip address it must “and” the ip address with the subnet mask. what you see 192 . 100 . 10 .
