What is the Internet?
The World Wide Web
A collection of interconnected networks
A place where a huge amount of information is stored
A single network controlled by a central computer
What is a URL (uniform Resource locator)?
A search engine
A web address
A web browser
A website
In a packet switching network:
Each packet contains the entire message being sent
All packets travel via the same route from sender to recipient
Any type of data (e.g. text, sound, images, video) can be sent
The sender decides how many packets are to be used
In a packet switching network, if the connection between two nodes on the route between sender and destination is broken:
the entire message must be resent
the packet takes an alternative route to the destination
the sender is notified that transmission has failed
he packet is delayed until the connection is restored
A domain name is:
a website address
a company name
a country name
part of a website address
A unique identifying number given to every computer each time it is connected to the internet:
Wi-Fi
Internet Protocol
IP Address
Software
Transmission Control Protocol
A device that connects multiple devices to the internet through the same physical internet connection:
Bit
Router
Wi-Fi
Hardware
Software
It is responsible for the formatting and addressing of the data packets being sent over the internet:
Hardware
Wi-Fi
Router
Internet Protocol
Transmission Control Protocol
It is responsible for dividing data into packets at one end of a transmission and reassembling those packets at the other end:
IP Address
Transmission Control Protocol
Internet Protocol
Router
Software
Which of these are examples of transmitting data
across the internet?
Playing a game online
Searching and loading information on Wikipedia for a school assessment
Writing an email
All of the above
What does every information packet on the internet
have?
A set of instructions of where it needs to
go and which route to take
A designated messenger and path of travel
The IP Address of where it's from and where it is going
A nice message from the sender to the receiver
Why does data need to be broken down into packets to
be sent over the internet?
It makes it easier for internet users to view the data being sent
The information may be too large to send in one go
It slows the system down so the internet doesn't get flooded with information
All of the above
What is an advantage of having a system that uses the
TCP and router to transmit data on the internet?
It is scalable- able to be used & reliable regardless of how many devices are on the system
It is the fastest way to send and receive data
It ensures data is sent and received safely in one go
All of the above
Which of these best describes fault-tolerance on the Internet?
The ability to stop cyberattacks
The ability to transmit data even when some connections have failed
The ability for DNS servers to retrieve the correct IP addresses of websites
The ability for the Internet to handle billions of unique users
Which of these best describes the scalability of the Internet?
The ability to stop cyberattacks
The ability to transmit data even when some connections have failed
The ability for DNS servers to retrieve the correct IP addresses of websites
The ability for the Internet to handle billions of unique users
Which of these best describes the redundancy of the Internet?
There are many different paths for information to travel from point A to point B.
Information on the Internet is broken up into packets.
A router directs a packet by reading its destination IP address.
The Internet can handle billions of unique users at once.
Which of the following is an advantage of fiber optic cable compared to copper wire?
It is faster
It is cheaper
It is easier to work with
It requires no physical connection
Transmission control protocol (TCP) splits data into
segments
groups
parcels
packets
What is packet switching?
A method of compressing data to save bandwidth
A method of encrypting data for secure transmission
A method of transmitting data by breaking it into smaller packets
A method of transmitting data in a single, continuous stream
