Nodes are individual devices or points in a network where data can be created, received, or forwarded, such as computers, routers, and servers. Packets are small units of data transmitted over a network, which include not only the payload (the actual data being sent) but also metadata like the destination address and error-checking information. Together, nodes and packets facilitate communication and data transfer within a network.

What are the distinct units of data that are exchanged between nodes on a network?
data packets
What are the distinct units of data that are exchange between nodes on a network?
data packets
What do you call data packets that are in a group and sent together?
Data packets that are in a group and sent together are called a frame. Data packets do not have to travel through unnecessary nodes so they can be sent quickly.
Can an ethernet HUB learns the MAC address and sends packets to the designated node?
Hubs, largely obsolete, are not capable of sending packets to specific nodes. It acts as a repeater to multiple nodes, and therefore all nodes on that hub share bandwidth. Switches learn MAC and IP addresses, and routers deal almost exclusively with IP addresses.
The distinct units of data that are exchanged between nodes on a network?
Data packets are the units of data that are exchanged between nodes on a network. A typical packet contains around 1,000 to 1,500 bytes.
Why is it that when the load exceeds the network capacity delay tends to infinity?
As load exceeds network capacity, packets gets jammed at nodes. These packets never go forward unless load goes below network capacity. Hence when load exceeds network capacity delay tends to infinity. As load exceeds network capacity, packets gets jammed at nodes. These packets never go forward unless load goes below network capacity. Hence when load exceeds network capacity delay tends to infinity.
What are the advantages of Router?
Routers allow data packets to travel faster on a computer network. This is by determining the shortest and best route between the sending and receiving nodes.

What are three benefits of IPv6?
this protocol routes data packets between networks . IP address specify the locations of the source and destination nodes in the topology of routing system.
Which command would an administrator use to identify all hops between two nodes?
An administrator can use the traceroute command (or tracert on Windows systems) to identify all hops between two nodes. This command sends packets to the destination and reports back the IP addresses of the routers that handle the packets along the route. By analyzing the output, the administrator can determine the path taken and the response times for each hop.
What is the difference between wavelet tree and wavelet packets?
Wavelet tree is recursively built applying decomposition and approximation filter only to the (father wavelet) approximation filter output at each step (or level). Wavelt packets, instead, are constructed by applying both filters to approximation and decomposition filter output resulting in a 2^(n+1)+1 nodes with respect to 2(n+1)+1 nodes of standard discrete wavelet tree
What is CSMACD and how does work?
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) is a network protocol used to manage how data packets are transmitted in Ethernet networks. It works by first checking if the network is free (carrier sense) before sending data. If a collision is detected (multiple nodes trying to transmit at the same time), all transmitting nodes stop and wait for a random amount of time before retransmitting. This helps prevent data packets from colliding and causing errors.
