A PAN typically covers a larger geographical area than a LAN.

A PAN allows for many users to share resources, whereas a LAN is for individual use.

A LAN is less secure than a PAN.

Give one example of where a PAN could be used.

Place the four layers of the TCP/IP stack in order from top layer (1) to bottom layer (4).

Application - 1, Transport - 2, Internet - 3, Link - 4

Link - 1, Internet - 2, Transport - 3, Application - 4

Transport - 1, Link - 2, Internet - 3, Application - 4

Internet - 1, Transport - 2, Application - 3, Link - 4

State two reasons why using a biometric authentication measure is better than password authentication for staff accounts.

Biometrics are unique to each individual and cannot be easily replicated or shared, unlike passwords which can be guessed or stolen.

Biometric systems can be more convenient for users as they do not have to remember a password.

Passwords are more secure than biometrics because they can be changed regularly.

Biometric systems are less secure because they can be easily bypassed with fake fingerprints or facial recognition.

Explain why it would not be appropriate for the café to use MAC address filtering on their wireless network.

MAC address filtering can be easily bypassed by spoofing a MAC address, making it not very effective for security.

MAC address filtering requires constant updating and management, which can be impractical for a café with many customers.

MAC address filtering is the most secure method for wireless networks and cannot be bypassed.

MAC address filtering does not provide any security benefits and is completely useless.

What is one difference between a LAN and a WAN?

A) A LAN is typically used for local file sharing, while a WAN is used to connect larger networks over greater distances.

B) A LAN is less secure than a WAN.

C) A WAN is used only within a single building.

D) A LAN can operate without any physical connections.

Why is HTTPS often used rather than HTTP?

B) Because HTTPS encrypts the data to provide secure communication over the Internet.

A) Because HTTPS is faster than HTTP.

C) Because HTTP supports digital certificates, whereas HTTPS does not.

D) Because HTTPS requires less data usage than HTTP.

What are the two other layers of the TCP/IP stack, in addition to the application and network (internet) layers?

D) Transport and Physical layers.

A) Presentation and Session layers.

B) Data Link and Physical layers.

C) Transport and Data Link layers.

What is the purpose of the network (internet) layer within the TCP/IP stack?

C) It is responsible for logical addressing and routing, enabling data to traverse multiple networks.

A) It is responsible for the actual physical transmission of data.

B) It provides encryption and secure communication protocols.

D) It ensures error-free data transmission between host computers.

What is the purpose of MAC address filtering in network security?

To restrict network access to authorized devices based on their MAC address

To encrypt data packets over the network

To increase the speed of the network

Which of the following is a measure to maintain the security of a computer system?

Regularly defragmenting the hard drive

Increasing the brightness of the monitor

Why might a school allow teachers to access the school network from home?

To facilitate lesson planning and grading

To reduce the cost of internet at home

Why might a school not allow teachers to access the school network from home?

To prevent potential security risks

To encourage teachers to stay at school longer

To limit the use of school resources

To avoid paying for teachers' home internet

What is one difference between a PAN and a LAN?

A LAN is used for connecting devices in a limited area, while a PAN is for personal area network

A PAN is typically larger than a LAN

A PAN uses only wired connections, while a LAN uses wireless

A LAN is used for personal devices, while a PAN is for office networks

What is a protocol in the context of computer networks?

A set of rules governing the exchange or transmission of data between devices

A device that connects multiple computers together
