Packets

What is the purpose of breaking down data into packets before transmitting it over a network?

• To reduce the size of the data
• To improve data security
• To improve data transmission efficiency
• To eliminate the need for routing

What are the components of a packet?

• Header, footer, data
• Header, payload, trailer
• Header, payload, data
• Header, footer, trailer

What is the purpose of the header in a packet?

• To identify the source of the packet
• To identify the destination of the packet
• To identify the type of data in the packet
• All of the above

Which of the following is NOT included in the header of a packet?

• Source IP address
• Destination IP address
• Payload data
• Protocol type

What is the purpose of the trailer in a packet?

• To identify the source of the packet
• To identify the destination of the packet
• To verify the integrity of the packet data
• To encrypt the packet data

What is packet switching?

• A process of transmitting data between two computers
• The process of breaking down data into packets
• The process of transmitting data across a network using routers
• The process of encrypting data before transmission

How does packet switching work?

• Each packet is sent to its destination directly
• Each packet may take a different route to its destination
• Each packet is checked for errors before being sent
• Each packet is sent with a unique identifier

What is a router in a network?

• A device that connects multiple networks together
• A device that encrypts data
• A device that stores data
• A device that filters data

What is the purpose of a router in a network?

• To connect multiple networks together
• To encrypt data
• To store data
• To filter data

Which of the following best describes the process of packet switching?

• Packets are sent from the source directly to the destination
• Packets are sent to a central server for processing before being sent
• Packets may take different routes to the destination and may arrive out of order
• Packets are sent with a unique identifier to ensure they are received in order
