1. Identify the network model shown below
Correct Answer
B. Peer-Peer model
Explanation
The network model shown below is the Peer-Peer model. In this model, each device in the network can act as both a client and a server, allowing for direct communication and file sharing between devices without the need for a centralized server. This model is commonly used in file-sharing applications and decentralized networks where all devices have equal capabilities and can communicate with each other.

2. The smallest type of network is..
Correct Answer
A. PAN
Explanation
A PAN (Personal Area Network) is the smallest type of network that connects devices within a short range, typically within a person's workspace or immediate surroundings. It allows for communication between devices such as smartphones, tablets, and laptops, as well as peripherals like printers and keyboards. PANs are commonly used for tasks like file sharing, wireless printing, and connecting devices to the internet. They are typically created using technologies like Bluetooth or Wi-Fi, and provide a convenient and efficient way to connect and interact with devices in a localized area.

3. A computer network is...
Correct Answer
D. All the above
Explanation
A computer network involves the sharing of resources, such as printers or storage devices, among multiple computers. It also enables communication between computers, allowing them to exchange data and information. Therefore, the correct answer is "All the above" as it encompasses all the mentioned aspects of a computer network.

4. Identify the image shown below
Correct Answer
C. Switch
Explanation
The image shown below is a switch. A switch is a networking device that connects multiple devices on a local area network (LAN). It operates at the data link layer of the OSI model and uses MAC addresses to forward data between devices. Unlike a hub, a switch can intelligently direct traffic to the appropriate device, increasing network efficiency. A router is used to connect multiple networks, and a gateway is a device that connects a LAN to the internet.

5. 192.168.10.3 is an example of...
Correct Answer
D. IP address
Explanation
192.168.10.3 is an example of an IP address. An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves as an identifier for the device and allows it to communicate with other devices on the network. In this case, 192.168.10.3 is a specific IP address assigned to a device.

6. A computer must have an IP address when..
Correct Answer
B. Connecting to a Wi-Fi hotspot
Explanation
A computer must have an IP address when connecting to a Wi-Fi hotspot because the IP address is a unique identifier that allows the computer to communicate with other devices on the network. When connecting to a Wi-Fi hotspot, the computer needs to obtain an IP address from the router or access point in order to establish a connection and access the internet. This IP address is necessary for routing data packets between the computer and other devices on the network, enabling communication and data transfer.

7. A home computer network is sometimes also called a…
Correct Answer
B. LAN
Explanation
A home computer network is sometimes also called a LAN, which stands for Local Area Network. A LAN is a network that connects devices within a limited area, such as a home or office building. It allows devices like computers, printers, and smartphones to communicate and share resources with each other. A LAN is typically owned and controlled by the user, making it suitable for home use.

8. Identify the image shown below
Correct Answer
C. Network Interface Card
Explanation
The image shown below is a Network Interface Card (NIC). A NIC is a hardware component that allows a computer to connect to a network. It is usually inserted into an expansion slot on the computer's motherboard and provides a physical connection between the computer and the network. NICs are essential for enabling communication between computers within a network and for accessing the internet.

10. What does LAN stand for?
Correct Answer
C. Local Area Network
Explanation
LAN stands for Local Area Network. It is a computer network that connects devices within a limited geographical area, such as a home, office, or building. LANs allow for the sharing of resources, such as printers and files, and enable communication between connected devices.

11. Thomas Mills High School has computers being used in a number of school buildings within the site.
Which network is being used?
Correct Answer
D. None of the above
Explanation
The question states that Thomas Mills High School has computers being used in a number of school buildings within the site. However, it does not provide any information about the network connecting these computers. Therefore, we cannot determine which network is being used based on the given information. Hence, the answer is "None of the above."

13. The amount of data that can be transferred over a network in a certain amount of time.
Correct Answer
D. Bandwidth
Explanation
Bandwidth refers to the amount of data that can be transferred over a network in a certain amount of time. It represents the capacity of the network to transmit data. A higher bandwidth allows for faster data transfer, while a lower bandwidth results in slower transfer speeds. Therefore, bandwidth is the correct answer as it directly relates to the given definition.

14. To test the IP stack on your local host, which IP address would you ping?
Correct Answer
C. 127.0.0.1
Explanation
The correct IP address to ping in order to test the IP stack on your local host is 127.0.0.1. This IP address is known as the loopback address and it represents the local machine itself. When you ping this address, the packets are sent to the network stack on your own computer and then returned back to the sender, allowing you to test the functionality of the IP stack without involving any external network devices.

15. You want to implement a mechanism that automates the IP configuration, including IP address, subnet mask, default gateway, and DNS information. Which protocol will you use to accomplish this?
Correct Answer
C. DHCP
Explanation
DHCP (Dynamic Host Configuration Protocol) is the correct answer. DHCP is used to automate the IP configuration process by assigning IP addresses, subnet masks, default gateways, and DNS information to devices on a network. It eliminates the need for manual configuration and allows for centralized management of IP addresses. SMTP (Simple Mail Transfer Protocol) is used for sending email, SNMP (Simple Network Management Protocol) is used for network management, and ARP (Address Resolution Protocol) is used for mapping IP addresses to MAC addresses.

16. Which class of IP address provides a maximum of only 254 host addresses per network ID?
Correct Answer
C. Class C
Explanation
Class C IP addresses provide a maximum of only 254 host addresses per network ID. This is because Class C addresses have a default subnet mask of 255.255.255.0, which allows for 256 total addresses. However, the first and last addresses are reserved for network and broadcast addresses respectively, leaving only 254 usable host addresses. Class C addresses are typically used for small to medium-sized networks.
