Understanding the Internet

Why is using satellites for internet transmission not preferred?

• Because it's too expensive

• It's preferred but not widely available

• Due to the long distance causing latency

• Satellites can't transmit data effectively

What is the backbone of the Internet?

• Undersea cables

• Cell towers

• Optical fiber networks

• Satellite communication

What does an IP address do in the internet?

• It encrypts data

• It stores data

• It increases internet speed

What happens if a data packet does not reach its destination?

• The packet is lost forever

• The destination device requests the packet again

• The entire message is resent

• The packet is converted into a different format

What role do protocols play in the internet?

• They design websites

• They manage the flow of data packets

• They physically lay down optical fiber cables

• They create new IP addresses

What institution manages IP address assignment and domain name registration?

• Google

• Internet Service Providers

• ICANN

• The United Nations

What is the Internet?

• A local network.

• Mobile phone network.

• Is the global system of interconnected computer networks that use the TCP/IP protocol to link devices worldwide.
