Tpr2_u3: The Internet 2/3

A LAN stands for Local Area Network, which refers to a network that covers a small geographical area such as a home, office, or school. It allows devices within this area to connect and communicate with each other, enabling the sharing of resources such as files, printers, and internet access. LANs are typically faster and more reliable than wide area networks (WANs) as they are confined to a smaller area.

The correct answer is "Yes, the printer and the phone are connected to the same network." This means that both the printer and the mobile phone are connected to the same Wi-Fi network, allowing them to communicate and print documents wirelessly.

The correct answer is the ISP (the telephone company) because the ISP is responsible for assigning and providing the public IP address to the router. The ISP is the service provider that connects the router to the internet and assigns a unique IP address to the router, allowing it to communicate with other devices on the internet.

The correct answer is 192.168.0.101. This IP address is most likely the internal (private) IP address of the laptop because it falls within the range of IP addresses commonly used for private networks. The IP address 192.168.0.101 is in the same subnet as the given IP address 192.168.0.100, suggesting that they are part of the same network. Additionally, the IP address 192.168.0.1 is commonly used as the default gateway for home networks, indicating that it is likely the router's IP address rather than the laptop's. The IP address 82.10.250.19 is a public IP address, which is assigned to devices on the internet and not typically used for internal networks.

The correct answer is Ethernet cable (RJ45) because desktop computers typically require a stable and high-speed internet connection, which is best achieved through a wired connection. Ethernet cables, specifically RJ45 cables, are designed to provide reliable and fast network connectivity between devices such as computers and routers. This type of connection ensures minimal interference and maximizes data transfer speeds, making it ideal for desktop computers. Wireless connections like WiFi or Bluetooth may also be used, but they are typically less reliable and slower compared to a wired Ethernet connection.

Based on the given information, it is stated that the router is turned off, which means that there is no internet connectivity provided by the router. Additionally, it is mentioned that the mobile phone is connected to the internet using a WiFi connection, and PC number 2 is connected to the internet using a wired connection. However, since the router is turned off, none of the devices have a connection to the internet using this network. Therefore, the correct answer is that none of the devices have a connection to the internet using this network.

The correct answer is "Wireless connection (WiFi)" because WiFi is a technology that allows devices to connect to the internet or communicate with each other wirelessly. It uses radio waves to transmit data over short distances. Unlike Ethernet cables or telephone cables, WiFi does not require physical connections and allows for greater mobility and flexibility in accessing the internet or sharing data between devices. Bluetooth is also a wireless technology, but it is primarily used for short-range communication between devices, such as connecting a smartphone to a wireless headset.

The correct answer is 192.168.0.1. This is because the IP address 192.168.0.1 is commonly used as the default gateway address for many routers. It is a private IP address that is used to access the router's configuration settings. The other IP addresses listed are also private IP addresses, but 192.168.0.1 is the most commonly used address for routers. The IP address 82.10.250.19 is a public IP address, which is assigned to devices on the internet.

The correct answer is 82.10.250.19. This is because the given IP address is in the format of a public IP address, which is used to identify devices on the internet. The other options provided (192.168.0.104, 192.168.0.101, 192.168.0.1) are in the format of private IP addresses, which are used for local network communication and cannot be directly accessed from the internet. Therefore, the only option that could be the external IP address of desktop computer number 2 is 82.10.250.19.

ISP stands for Internet Service Provider. An ISP is a company that provides internet access to individuals, households, businesses, and other organizations. They offer various types of internet connections, such as broadband, DSL, cable, and fiber optic, allowing users to connect to the internet and access online services, websites, and other digital content. ISPs also often provide additional services like email accounts, web hosting, and virtual private networks (VPNs). Overall, ISPs play a crucial role in enabling internet connectivity and facilitating communication and access to information for users worldwide.

When the router is unplugged from the telephone line, all devices connected to the network lose their connection to the Internet. This includes the mobile phone, which relies on a WiFi connection, and PC number 6, which uses a wired connection. As a result, it is not possible to print a document from PC number 6 because it cannot access the Internet. Therefore, the correct answer is that none of the devices have a connection to the Internet using this network.

The correct answer is 82.10.250.19. This is because the IP address 192.168.0.x is a private IP address range that is used for local networks, such as home or office networks. These IP addresses are not accessible or routable on the internet. The IP address 82.10.250.19, on the other hand, is a public IP address that can be accessed over the internet. Therefore, it is the external (public) IP address of the laptop.

The external (public) IP address of a device refers to the unique identifier assigned to it on the internet. In this case, the correct answer is 82.10.250.19. This IP address is a public address that can be used to access the mobile phone from outside the local network. The other IP addresses listed (192.168.0.100, 192.168.0.101, and 192.168.0.1) are private IP addresses commonly used within local networks for communication between devices.

The router is responsible for providing the local IP address 192.168.0.101 to the laptop. The router acts as a central hub for connecting multiple devices to a network and manages the distribution of IP addresses. It assigns unique IP addresses to each device connected to it, allowing them to communicate with each other and access the internet. Therefore, in this scenario, the router is the device that assigns the local IP address to the laptop.

LAN ports on a modem-router can be connected to wired devices such as PCs and printers using Ethernet cables (RJ45). This is because Ethernet cables are designed to transmit data between devices over a local area network. The other options mentioned, such as connecting the telephone line using a telephone cable (RJ11) or Ethernet cable (RJ45), or connecting wireless devices, are not applicable to LAN ports on a modem-router.

The modem-router mentioned in the question has an antenna, which indicates that it is capable of wireless connectivity. Therefore, wireless devices such as mobile phones and tablets can connect to the modem-router using the antenna. Wired devices like PCs and printers would connect to the modem-router using Ethernet cables, while the telephone line would typically use a telephone cable or an Ethernet cable with an RJ11 connector.

The correct answer includes the essential components of a typical home network. A router is necessary to connect all the devices together and provide internet access. Desktop computers, a mobile phone, a laptop, and a smart TV represent the various devices that can connect to the network and access the internet. A printer is also included as it can be connected to the network to enable wireless printing from any device.

The correct answer is "The telephone line using an Ethernet cable (RJ45)." This is because ADSL (Asymmetric Digital Subscriber Line) technology uses Ethernet cables (specifically, RJ45 connectors) to connect the modem-router to the telephone line. RJ45 connectors are commonly used for Ethernet connections, allowing for high-speed data transmission over the telephone line.

The correct answer is that you can print a document from your laptop using the printer because the laptop and the printer are interconnected and the router is on. This suggests that the printer is connected directly to the laptop, possibly through a USB cable, and the router is providing the necessary network connectivity for the laptop to communicate with the printer. Therefore, even if the router is unplugged from the telephone line and there is no internet connection, the laptop can still communicate with the printer and print documents.

This modem-router can connect up to 4 PCs and up to 30 mobile phones (more or less) to the internet. It supports both wired and wireless devices, allowing for a combination of both types of connections.
