What else can I help you with?
Which is a device that forwards packets between networks by processing the routing information included in the packet?
A router is a networking device that forwards data on a network.
What is the most importand function of a router?
A router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect, and are the critical device that keeps data flowing between networks and keeps the networks connected to the Internet.
What is a router and what are its purpose?
router networking/roo't*/ A device which forwards packets between networks. The forwarding decision is based on network layer information and routing tables, often constructed by routing protocols.
What are Moving packets from source to destination across multiple networks called?
Router
What is inter-arrival time in computer networks?
It is the time between successive packets.
Variable-length packets and ststistical multiplexing are characteristics of?
... packet-switching networks.
Why cant routers forward packets as fast as bridges can?
It is a fact that bridges forward packets faster when compared to routers. Because router takes time to find the shortest path between source and destination,whereas bridges directly forwards the packets.
What is a solution that requires packets to pass in and out of a device?
A common solution that requires packets to pass in and out of a device is a router. Routers manage the traffic between different networks by forwarding data packets based on their destination IP addresses. They receive incoming packets, determine the best path for them, and then send them out to their next destination. This process is essential for enabling communication between devices on different networks, such as connecting a home network to the internet.
What converts private IP addresses into normal IP address when it forwards packets from those computers to the Internet?
network address translation device
What protocol assists in determining whether packets reach their intended destination?
The Answer is ICMP - A core protocol in the TCP/IP suite that notifies the sender that something has gone wrong in the transmission process and that packets were not delivered. Page 177. Networks + Guide to Networks 5th edition.
On a VoIP network that uses the DiffServ QoS technique what makes certain that a router forwards packets within a given time period?
Expedited Forwarding
Why IP is consider as a best effort protocol?
Internet Protocol (IP) is considered a best-effort protocol because it does not guarantee the delivery of packets, their order, or error correction. IP simply forwards packets based on their destination address, without ensuring reliability or quality of service. If packets are lost, delayed, or arrive out of order, IP does not provide mechanisms to rectify these issues, leaving it up to higher-layer protocols, like TCP, to manage reliability and flow control. This design allows for simplicity and efficiency in routing data across diverse networks.
