Bandwidth, Latency, throughput, goodput
Bandwidth is the capacity at which a medium can carry data.
Latency - Amount of time, including delays, for data to travel from one given point to another
Throughput - The measure of the transfer of bits across the media over a given period of time
Goodput - The measure of usable data transferred over a given period of time
what is transport layer in charge of
- Logical communications between applications running on different hosts
- Link between lower layers that are responsible for network transmission and application layers
what is the private addresses for IPv4
10.0.0.0 to 10.255.255.255 ( 10.0.0.0/8)
172.16.0.0 to 172.31.255.255 (172.16.0.0/12)
192.168.0.0 to 192.168.255.255 (192.168.0.0/16)
what is dhcp
automatically assigns IP addresses, subnet masks, default gateways, and other network configuration information to devices on a network. It eliminates the need for manual configuration of network settings, making it easier to manage large networks and add new devices to the network.
what is a banner

broadcast
the process of sending a packet from one host to all hosts in the network.
multicast
process of sending a packet from one host to a group of hosts in the network which subscribes to a special range of address called a multicast address
