What is broadband?
A slow internet connection
A high-speed internet connection
A type of wireless router
A network topology
Why is download speed usually faster than upload speed?
Because files are smaller
Because networks prioritize downloads

Because of buffering
What does buffering mean?
Increasing bandwidth
Storing data temporarily before playing
Compressing files
Encrypting data
Which of these is a disadvantage of wireless connectivity?
Requires cables
Slower than wired
Cannot connect mobile devices
No security risk
Which of these is true about fibre optic cables?
They use copper wires
They can carry terabytes per second
They are slower than dial-up
They cannot be used for broadband
What does Mbps stand for?
Mega Bytes per Second
Mega Bits per Second
Micro Bits per Second
Which factor can cause buffering?
High bandwidth
Slow download speed
Wired connection
Fibre optic cable
Define bandwidth.
The amount of data that can be transmitted at a time.
The speed at which a computer processes data.
The physical size of a network cable.
The number of devices connected to a network.
What is broadband?
A high-speed internet connection that replaced dial-up.
A type of wireless headphone.
A brand of television.
A software for editing photos.
Why does buffering occur?
When media plays faster than it downloads, data is stored temporarily.
When the internet connection is extremely fast.
When the device has unlimited storage.
When the media file is already fully downloaded.
State one advantage and one disadvantage of wireless connectivity.
Advantage: No physical cables needed. Disadvantage: Slower and less secure.
Advantage: Requires physical cables. Disadvantage: Faster and more secure.
Advantage: No internet required. Disadvantage: Always reliable.
Advantage: Unlimited range. Disadvantage: No interference.
How is internet speed measured?
In bits per second (e.g., Mbps).
In kilograms per hour.
In liters per second.
In degrees Celsius.

Bus
Network topology is defined as:
The arrangement of various elements (links, nodes, etc.) in a computer network.
A type of computer virus.
A programming language used for networking.
A security protocol for wireless networks.
A mesh network is considered reliable because:
it provides multiple paths for data to travel, reducing the risk of failure
it uses only one central node for communication
it is the least expensive network topology
it requires no maintenance
The role of a switch in a network is:
To connect devices and forward data only to the intended recipient.
To provide wireless connectivity to devices.
To assign IP addresses to devices.
To block all network traffic.
What is an IP address?
A human-readable website name
A unique numerical label assigned to a device
A type of network cable
A protocol for sending emails
What does a data packet contain?
Only the sender’s address
Only the receiver’s address
Both sender’s and receiver’s addresses
No address information
An IP address is defined as:
A unique identifier for a device on a network
A type of computer virus
A programming language
A hardware component of a computer
What is a domain name?
A numerical device address
A human-readable website name
A network protocol
A hardware identifier
Which system translates domain names into IP addresses?
DHCP
DNS
HTTP
FTP
Which of these is an example of a domain name?
142.250.185.78
www.google.com
255.255.255.0

Humans find IP addresses easier to remember
DNS is optional for websites
A device can only have one IP address
Which is the correct analogy for domain names and IP addresses?
Domain name = phone number, IP address = contact name
Domain name = contact name, IP address = phone number
Both are phone numbers
Both are contact names
A domain name is:
A unique address used to identify a website on the internet.
A type of computer hardware.
A programming language.
A social media platform.
DNS is a system that:
Translates domain names into IP addresses
Stores website content
Manages email delivery
Secures network connections
3. Identify the protocol in the following URL: https://www.example.com
FTP
HTTP
HTTPS
SMTP
DNS is important because:
It translates domain names into IP addresses.
It stores website content.
It creates internet protocols.
It manages user passwords.
One difference between a domain name and an IP address is:
A domain name is easier for humans to remember, while an IP address is a numerical label.
A domain name is a type of computer hardware, while an IP address is software.
A domain name is used only for emails, while an IP address is used for websites.
A domain name and an IP address are always the same.
