What is an IP address?
A unique identifier assigned to each device on the Internet
A type of Internet service provider
A password required to access the Internet
A software that protects devices from viruses
Which of the following is an example of an IPv4 address?
2001:0db8:85a3:0000:0000:8a2e:0370:7334
139.130.4.5
12345:678:90
ABCD:EF01:2345:6789:ABCD:EF01:2345:6789
Why was a longer IP address system introduced?
To increase the speed of the Internet
To allow for more devices to be connected to the Internet
To improve the security of Internet communications
To reduce the cost of Internet access
When accessing the internet, what is required no matter what kind of device you use?
A) A web browser
B) An IP address
C) A search engine
D) A social media account
What happens to a web page when it is sent from the server to a client computer?
A) It is sent as a continuous stream of data.
B) It is sent in large chunks without an address.
C) It is split into small chunks called packets, each with the IP address of the client.
D) It is compressed into a single packet with encryption.
If packets do not make it to the client, what might happen?
A) The client computer will crash.
B) The entire data set may be sent again or just the packets that were lost.
C) The server will automatically shut down.
D) The packets will be lost forever.
Which might be more important for a user streaming a video game?
A) 100-percent packet accuracy
B) The color quality of the display
C) The size of the web page
D) The number of advertisements
What is the process of splitting data into packets and sending them over the internet known as?
Data encoding
Packet switching
Protocol streaming
Data fragmentation
What are the rules known as that determine how computers send and receive data?
Guidelines
Protocols
Instructions
Procedures
How many layers are used in the TCP/IP model according to the text?
Two
Three
Four
Five
Which protocol is the standard for how web pages are displayed on the web?
SMTP
HTTP
POP3
IMAP
What is the difference between IMAP and POP3?
IMAP saves changes on the server, while POP3 saves changes only on the local device.
IMAP is used for sending emails, while POP3 is used for receiving emails.
IMAP is less secure than POP3.
IMAP is faster than POP3.
What is the role of the Transmission Control Protocol (TCP) layer mentioned in the text?
It labels each packet with the IP address of the destination device.
It deals with breaking down data and opening channels of communication between applications.
It determines the best route for each packet to take.
It ensures that all packets travel along the same route.
What analogy is used in the text to explain the function of the IP layer?
A group of people taking different routes to reach the Empire State Building in rush hour traffic.
A bus getting stuck in traffic while carrying people to a destination.
Packets traveling along the same route to reach the destination.
A kayak traveling along the East River.
What is the main function of the IP layer as described in the text?
It uniquely identifies a network-based application with a port number.
It breaks down data into packets for communication.
It labels each packet with the IP address of the destination device and determines the best route for each packet.
It ensures that all packets are sent along the same route.
What is the most common protocol in the hardware layer?
TCP/IP
MAC
Ethernet
IP
What does the hardware layer deal with in the TCP/IP model?
Routing of packets
Encryption of data
Physical transport of packets
Data storage
Can a MAC address change when a device connects to different networks?
Yes, it changes with the network
No, it is installed on the NIC and cannot change
Yes, it changes with the IP address
No, it changes with the device's location
What is the purpose of the MAC address in the hardware layer?
To encrypt the data on the packets
To identify the specific device to send the message to
To change the IP address depending on the network
To store data on the network interface card
What is the original message sent from Host 1 in the diagram?
Red, Blue, Green
Blue, Green, Red
Green, Red, Blue
Green, Blue, Red
