Answer:

An algorithm is a step by step process that describes how to solve a problem in a way that always gives a correct answer.

An algorithm is made up of three basic building blocks: sequencing, selection, and iteration.

Sequencing: An algorithm is a step-by-step process, and the order of those steps are crucial to ensuring the correctness of an algorithm.

Selection: Algorithms can use selection to determine a different set of steps to execute based on a Boolean expression.

Iteration: Algorithms often use repetition to execute steps a certain number of times or until a certain condition is met.

Which of the following is true of how packets are sent through the Internet?

astra-53 [7]

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.

Suppose the sender wants to send the following bit stream by using bit stuffing. What would the sender transmit if the following

Helen [10]

The purpose of bit stuffing is used as a delimiter to mark the end of one frame and the beginning of the next frame.

<h3>What is Bit Stuffing?</h3>

This refers to the use of one or more information bits in order to break up the message for easy synchronization.

The parts of a frame are:

Frame header
Payload field
Trailer
Flags.

This is a bit pattern that is used to define the start and end bits in a given frame and the 8-bit pattern 01111110 as the flag is commonly used.

Hence, we can see that your question is incomplete so I gave you a general overview to help you have a better understanding of the concept.
