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:
zeroIt(&x);
Explanation:
The statement that sets the value stored in x to zero by invoking the function zerolt is given below
zeroIt(&x);
The zeroIt function is also given below for better understanding.
void zeroIt(int *x) {
*x = 0;
}
As seen, the function takes an argument with integer variable type, which is a pointer, denoted by the asterisk symbol (*x).
The ampersan sign (&x) is used to access the variable whose value can then be stored.
