Explain the difference between IPv4 and IPv6.
IPv4 is a 32-bit address scheme with about 4.3 billion addresses; IPv6 is a 128-bit scheme with a vastly larger address space.
IPv4 uses hexadecimal addresses while IPv6 uses decimal addresses.
IPv4 is primarily used for mobile devices, while IPv6 is for desktop computers.
IPv4 can support more devices than IPv6 due to its larger address space.

What is bandwidth in the context of data transmission?
Bandwidth is the number of devices connected to a network.
Bandwidth is the amount of time data takes to travel from one point to another.
Bandwidth is the maximum data transfer rate of a network connection.
Bandwidth refers to the physical size of a network cable.
What is a firewall and how does it enhance network security?
A firewall is a device that boosts internet speed by compressing data.
A firewall is a type of antivirus software that scans for malware.
A firewall is a network security device that monitors and controls traffic to enhance security by blocking unauthorized access.

What is the client-server model?
A model where servers request services from clients.
A method for storing data on a local device.
The client-server model is a distributed architecture where clients request services from servers that provide those services.
A single computer system that does not involve networking.
How does a client communicate with a server?
A client communicates with a server by sending emails to its administrator.
A client communicates with a server by directly accessing its database.
A client communicates with a server by sending requests and receiving responses over a network.
A client communicates with a server by using physical mail to send requests.
What is the role of a web server?
