Answer: They are forms of of carrying data from communication devices. The difference is the medium where the signal travels.
Explanation:
Hi, the difference between guided and unguided media is that in the guided media, the signal travels through a physical medium whereas, in unguided media, the signal travels through the air.
Guided and unguided media are types of transmission media.
The transmission media carries electromagnetic signals, that transmit data between communicating devices like computers.
Answer:
It is A: Packet metadata is used to route and reassemble information travelling through the internet.
Explanation:
Step 1: The Internet works by chopping data into chunks called packets. Each packet then moves through the network in a series of hops. Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee
Step 2: Entering the network
Each packet hops to a local Internet service provider (ISP), a company that offers access to the network -- usually for a fee.
Step 3: Taking flight
The next hop delivers the packet to a long-haul provider, one of the airlines of cyberspace that quickly carrying data across the world.
Step 4: BGP
These providers use the Border Gateway Protocol to find a route across the many individual networks that together form the Internet.
Step 5: Finding a route
This journey often takes several more hops, which are plotted out one by one as the data packet moves across the Internet.
Step 6: Bad information
For the system to work properly, the BGP information shared among routers cannot contain lies or errors that might cause a packet to go off track – or get lost altogether.
Last step: Arrival
The final hop takes a packet to the recipient, which reassembles all of the packets into a coherent message. A separate message goes back through the network confirming successful delivery.

Answer:
c. let v = silo.volume();
Explanation:
When you create and initialize a new object you pass through that object's class constructor. The constructor is in charge of initializing all the necessary variables for that class including radius and height. Once you save the object in a specific variable (silo) you need to call the class methods through that variable, using the '.' command. Therefore, in this scenario, in order to call the volume() method you would need to call it from the silo object and save it to the v variable, using the following statement.
let v = silo.volume();
Both yeah and no, depending on personal opinion
