packets must travel on a specific path to reach their destination
packets may travel on any possible path to reach their destination
packets are processed as they travel from one node to the next

The chart shown explains the IPv4 hierarchy. Which of the following best correlates with an IP address.
from left to right, with increasingly specificity to reach a target device
each part of the IPv4 quad is randomly generated

Which of the following best describes the protocols used on the Internet?
The protocols of the Internet are secret to maintain the privacy and security
The protocols of the Internet are used by all devices connected to the network
A protocol for sending packets that does error-checking to ensure all packets are received and properly ordered.
Transmission Control Protocol (TCP)
User Datagram Protocol (UDP)
The maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.
Path

Flexibility:
Expandability:
Scalability:
Variablilty:
Data added to packets to help route them through the network and reassemble the original message.
Computer ID:
Packet Metadata:
IP Address:
Router Number:
Can continue to function even in the event of individual component failures. This is important because elements of complex systems like a computer network fail at unexpected times, often in groups.
Bandwidth:
IP Address:
Router:
Fault Tolerant:
A protocol for sending packets quickly with minimal error-checking and no resending of dropped packets
Router Protocol:
User Datagram Protocol (UDP):
IP Protocol:
Transmission Control Protocol (TCP):
An Internet Service Provider (ISP) is a company that builds the routers and wired connections that allow individuals to access the Internet. An ISP is considering adding additional redundant connections to its network. Which of the following best describes why the company would choose to do so?
It costs less to design a network that is redundant
The protocols of the Internet only work on networks that are redundant
Redundant networks are more reliable

Which of the following is NOT true of how computers represent complex information?
Common abstractions that are represented by computing devices include numbers, characters, and colo
Abstraction helps represent complex information by surfacing complexity that might otherwise be hidden
Which of the following is FALSE about routers and routing on the internet?
The central DNS server determines the shortest route for a packet to take between two IP addresses.
Each router independently determines how to pass along each packet it receives.
Packets often arrive in the wrong order or are lost entirely.
Routers will attempt to find the quickest route to the packet's destination based on the information available to the router's software.
Which of the following is true about TCP/IP packets?
Packets that are part of the same message may take different routes from sender to receiver.
TCP guarantees that no packets are dropped in transit.
Packets must arrive in the correct order at the receiver.
If a packet is dropped, the entire message must be resent in order.
How does a computer resolve a domain name into an IP address?
It asks its assigned DNS server.
It checks its etc/hosts file.
It consults the DDOS exchange.
It is provided by the DHCP server on the server's subnet.

A much larger number of unique IP addresses is available.
More than 4 gigabytes of memory can be used on the internet with IPv6.
Greater resistance to DDoS attacks.
Higher bandwidth for streaming video.
