Mbps stands for megabits per second, which is a unit used to measure the speed of data transmission in a network. It represents the number of megabits that can be transmitted in one second. This unit is commonly used to describe internet connection speeds, indicating how quickly data can be transferred from one node to another node in a network.

The given address "20:B9:F1:63:2F:FB" is a MAC address. MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communications at the data link layer of a network segment. It is used to uniquely identify devices on a local network. IP address is used to identify devices on a network at the internet layer, TCP/IP is a protocol suite used for internet communication, and HTTP is a protocol used for transferring hypertext over the internet.

The given description states that each node is connected with the help of a single coaxial cable. This is a characteristic of a bus topology, where all nodes are connected to a central cable. In a bus topology, data is transmitted in both directions along the cable, and each node receives the data and determines if it is intended for them.

TCP/IP is the most common communication protocol on the internet that ensures end-to-end communication. TCP (Transmission Control Protocol) is responsible for breaking data into packets and reassembling them at the destination, while IP (Internet Protocol) is responsible for addressing and routing these packets across the network. Together, TCP/IP provides a reliable and efficient method for data transmission over the internet, making it the standard protocol for internet communication. FTP (File Transfer Protocol), HTTP (Hypertext Transfer Protocol), and SLIP/ppp (Serial Line Internet Protocol/Point-to-Point Protocol) are also used for specific purposes, but they do not provide the same level of end-to-end communication as TCP/IP.

The correct answer is IP Address. An IP address is a unique numerical label assigned to each device connected to a computer network. It consists of four parts separated by periods and is used to identify and locate devices on the internet. IP addresses allow devices to communicate with each other and enable data transfer across networks.

The two students have formed a PAN (Personal Area Network) by connecting their laptops using Bluetooth. A PAN is a network that is used for communication between devices in close proximity to each other, typically within a range of 10 meters. In this case, the students are using Bluetooth to create a small network for working on their seminar presentation.

FTP stands for File Transfer Protocol. It is a protocol/technology used to exchange files on the internet. FTP allows users to transfer files from one computer to another over a network, such as the internet. It provides a simple and efficient way to upload, download, and manage files on remote servers. FTP is commonly used by web developers, system administrators, and individuals who need to transfer large files or multiple files between computers.

A URL, which stands for Uniform Resource Locator, is a string of characters that provides the address for a resource on the internet. It is commonly used to locate web pages, images, videos, and other files. A URL typically consists of several parts, including the protocol (such as HTTP or HTTPS), the domain name or IP address, and the specific path or location of the resource. The URL serves as a unique identifier for the resource, allowing users to access it through web browsers or other internet-enabled applications.

A repeater should be used to amplify the signal between the two neighborhood schools. A repeater is a device that regenerates and amplifies the signal, allowing it to travel further without loss. By using a repeater, the schools can overcome the loss of signal and successfully share their E-Learning resources.

A modem is a device that converts data from a digital bit stream into an analog signal and vice-versa. It is used to transmit data over telephone lines by converting digital signals from a computer into analog signals that can be transmitted over the phone line, and then converting the analog signals back into digital signals at the receiving end. This allows for the transmission of data between computers over long distances using existing telephone infrastructure.

A coaxial cable is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, which is then surrounded by a tubular conducting shield. This design allows the cable to transmit signals with minimal interference and loss of signal quality. Coaxial cables are commonly used in telecommunications, cable television, and computer networks to transmit data and video signals.

The relevant communication protocols that will allow Joy to upload and download files from/to a remote Internet server are FTP and HTTP. FTP (File Transfer Protocol) is specifically designed for transferring files between a client and a server on a computer network. HTTP (Hypertext Transfer Protocol) is the protocol used for transmitting hypertext over the internet, which includes the ability to download files. By using both FTP and HTTP, Joy will have the necessary protocols to perform file transfers in both directions.

Bluetooth is a communication channel that allows for the exchange of data over a short distance from both fixed and mobile devices. It is a wireless technology that uses radio waves to transmit data between devices such as smartphones, tablets, and computers. Bluetooth is commonly used for connecting devices like headphones, speakers, keyboards, and other peripherals to a computer or mobile device. It provides a convenient and reliable way to transfer data without the need for physical cables, making it ideal for short-range communication between devices.

A router is the most suitable network device to minimize network traffic. Routers are designed to efficiently direct network traffic between different networks, such as local area networks (LANs) and wide area networks (WANs). They use routing tables to determine the best path for data packets to reach their destination, which helps to optimize network traffic flow. Additionally, routers can also implement network segmentation by creating separate subnets, which can further reduce unnecessary network traffic by limiting broadcasts and isolating network segments.

In a hilly area, the most appropriate wireless communication channel would be a microwave. This is because microwave signals have a higher frequency and shorter wavelength, allowing them to easily penetrate obstacles such as hills and trees. Microwave communication is commonly used in hilly areas for various purposes, including television broadcasting, cellular communication, and satellite communication.

TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is a set of protocols that allows computers to communicate with each other over the internet. The Transmission Control Protocol (TCP) ensures reliable and ordered delivery of data packets between devices, while the Internet Protocol (IP) is responsible for addressing and routing the packets across networks. TCP/IP is the foundation of the internet and is used for various applications such as web browsing, email, file transfer, and more.

Coaxial cable is a suitable choice for connecting computers in a local area network within a 50m distance. It is an economical option that provides high-speed data transfer. Coaxial cable consists of a central conductor surrounded by a layer of insulation, a metallic shield, and an outer protective layer. This design allows for efficient transmission of data signals while minimizing interference. Coaxial cable is widely used in networking applications due to its affordability, reliability, and ability to support high-speed data transfer.

Bus topology is ideal for long-distance networking because it uses a single cable to connect all devices in a linear manner. This allows for easy expansion and flexibility, making it suitable for long-distance networks. Additionally, the use of a single cable reduces the cost and complexity of the network, making it a cost-effective option for long-distance networking.

Satellite is the correct answer because it refers to a man-made object that orbits the Earth and is used for various purposes, including communication between different countries. Satellites are equipped with communication devices that allow them to transmit signals across long distances, enabling communication between people in different countries. They play a crucial role in international telecommunications and help bridge the gap between nations by facilitating efficient and reliable communication.
