Why do computers represent all data as binary?
Binary simplifies complex code into a
language a computer can easily understand
Binary can be understood by any user, allowing all users and devices easy access to content and data
Binary has only two states, making it
easier for computers to process and take up less space
Binary allows coders to easily create programs
for any type of computer
What is 01001101 in decimal form?
63
77
95
123
How does binary get physically sent over
the internet?
By earth, wind and fire
By sending on and off signals using light posts
By sending small parcels with the binary code written inside it
By light, electricity and radio waves
How does a wireless system (WiFi connection) transmit
data on the internet?
It converts binary to radio waves on sending, then converts the radio waves to binary when receiving
It sends data in binary across the atmosphere to different devices
It uses the radio channels that we have to send data across and communicate with other devices
Wireless systems do not exist
Select the most correct statement:
An ethernet cable connection uses electricity to transmit data. It is expensive to install, but has no signal loss and is extremely fast.
An ethernet cable connection uses electricity to transmit data. It is cheap to install, but has significant signal loss after a short distance.
A fibre optic connection uses light to transmit data. It is extremely fast and cheap to install, but cannot transmit data over long distances.
A fibre optic connection uses sound waves to transmit data. It is hard to work with, but can transmit data over long distances and is very fast.
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
The internet transmits data through different routers and paths. What is an advantage of having the system setup this way?
It means that people can be assured that routers are transporting packets of data a little bit at a time, to avoid data loss
It makes the internet a fast system because the most direct path is being chosen to route different packets
It makes it a fault tolerant system, meaning that if there is a fault detected, the routers can find alternate paths to deliver packets
There is no advantage to this system- it is highly inefficient and needs to be improved
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
