best path to transfer packets from a computer, over the network, to the desired destination. The Network layer protocols consist of: Internet Protocol (IP), Address Resolution Protocol (ARP), Reverse Address Resolution Protocol (RARP), and Internet Control Message Protocol (ICMP). Internet Protocol (IP) provides for the network identification through addressing and User Datagram Protocol (UDP)/ connectionless delivery of packets. IP moves the data from point A to point B and is known as the best-effort

relies on the network layer (3) to provide host-to-host communication. There’s a piece of network layer in every host and router in the network. Transport segment from sending to receiving host. On sending, Host 1 encapsulates segments into datagrams. On receiving, Host 2 delivers datagrams to transport layer. Protocols in every host, router. Router examines header fields in all IP datagrams passing through it. Moves packets from sending to receiving hosts. Routers: forwards datagrams from input links

Semester Two Journal and Study Guide CISCO SYSTEMS NETWORKING Academy CCNA 2 Chapter 1 WANs and Routers One major characteristic of a wide-area network (WAN) is that the network operates beyond the local LAN's geographic scope. It uses the services of carriers, such as regional Bell operating companies (RBOCs), Sprint, and MCI. WANs use serial connections of various types to access bandwidth over wide-area geographies. By definition, the WAN connects devices that are separated by wide areas. WAN

IPv6 Protocol Text from presentation Sl2: Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) in 1998 (RFC2460) to deal with the long-anticipated problem of IPv4 address exhaustion. Sl3: Every device on the Internet must be assigned an IP address

(DNS) Domain Name System is a database system that translates a computer's fully qualified domain name into an IP address. Then there is (DHCP) Dynamic Host Configuration Protocol) which is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP). Now in DNS networked computers use IP addresses to locate and connect to each other, but IP addresses can be difficult for people to remember

1. What role does TCP/IP play for Internet communications? The Internet Protocol (IP) is the main communications protocol in the internet protocol suite for relaying datagrams across network boundaries its routing function enables inter networking and essentially establishes the internet. 2. IP being the primary protocol has the task of delivering packets from the source host to the destination host based on IP addresses in packet headers. So IP defines packet structures that contain the data

IP v6 Introduction: IPv6 or IP version 6 is the next generation Internet protocol which will eventually replace the current protocol IPv4.it is the communication protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF). IPv6 has a number of improvements and simplifications when compared to IPv4. The primary difference is that IPv6 uses 128 bit addresses as compared
