A router, wireless router, access point (AP), or wireless access point (AP) is needed to create a wireless link. These devices are responsible for transmitting and receiving wireless signals, allowing devices to connect to a network without the need for physical cables. They act as a bridge between the wired and wireless networks, enabling communication between devices. Different terms such as router, wireless router, AP, and access point are used interchangeably to refer to these devices.

To set up a computer network, one would require a hub, switch, bridge, router, server, workstation, or repeater. These devices play different roles in establishing and managing the network. A hub is a central connection point that allows multiple devices to be connected together. A switch is an intelligent device that directs network traffic to specific devices. A bridge connects multiple networks together. A router connects different networks and directs data packets between them. A server provides services and resources to other devices on the network. A workstation is a computer used by an individual for work. A repeater amplifies and extends the network signal.

The maximum approximate broadcast distance of a WPAN is 10 meters.

The maximum approximate broadcast distance of a WLAN is 100m, 100meters, 100 m, or 100 meters. This means that the wireless signal from a WLAN can typically reach up to 100 meters in distance before it starts to weaken and lose its strength.

The structure of telecommunication networks consists of three main components: the control plane, the user plane, and the management plane. The control plane is responsible for establishing and maintaining connections between network devices, while the user plane is responsible for the actual transmission of data. The management plane, on the other hand, is responsible for the overall management and control of the network, including tasks such as configuration, monitoring, and troubleshooting. Therefore, the correct answer is the management plane, which plays a crucial role in ensuring the smooth operation and maintenance of telecommunication networks.

A LAN (Local Area Network) is a type of computer network that is designed to cover a limited geographical area, such as an office or a building. It allows multiple devices, such as computers and printers, to be connected and share resources within the same area. Unlike a WAN (Wide Area Network) or MAN (Metropolitan Area Network), a LAN is typically smaller in scale and is privately owned and operated. Therefore, the given answer, LAN, is the correct choice as it accurately describes a network that covers a limited geographical area like an office.

A WAN (Wide Area Network) is a computer network that spans a large geographical area, typically covering a state or country. It connects multiple local area networks (LANs) and allows for the transmission of data and communication between different locations. Unlike LANs, which are limited to a small area such as an office or building, WANs provide connectivity over longer distances. Therefore, the correct answer is WAN.

The correct answer is Internet. The Internet is a global network of interconnected networks that allows for universal communication services over different physical networks. It enables the exchange of information and data between devices and users worldwide, regardless of the specific physical network they are connected to.

A transceiver is a device that combines both the functionality of a transmitter and a receiver in a communication infrastructure. It is capable of both sending and receiving information, making it an end node that can actively participate in the communication process. This makes the transceiver an essential component in various communication systems, such as wireless networks, where it can both transmit data to other devices and receive data from them.

Radio broadcast requires one powerful transmitter and many receivers. The transmitter sends out radio waves, which are then picked up by receivers such as radios. This allows for the transmission of audio signals over long distances, making it an effective method for broadcasting news, music, and other forms of entertainment. Unlike other options such as wireless broadcast, telephone, and wifi, radio broadcast specifically involves the use of radio waves for communication.

In a star LAN layout, all nodes are individually connected to a central connection point, such as a hub or a switch. This central point acts as a communication hub, allowing all nodes to communicate with each other. This layout is commonly used in Ethernet networks as it provides better performance and reliability compared to other layouts. Nodes can easily be added or removed without affecting the rest of the network, making it a flexible and scalable option.

Fibre optic is the correct answer because it is a network medium that uses light to transmit data. Unlike twisted pair and coaxial cable, which use electrical signals, fibre optic cables use pulses of light to carry information. This technology allows for faster data transmission and longer distances without signal degradation. Bluetooth, on the other hand, is a wireless communication technology that does not require a physical medium like fibre optic cables.

Network protocols are formal standards and policies that define communication between devices over a network. They consist of rules, procedures, and formats that ensure efficient and reliable data transmission. These protocols govern how data is transmitted, received, and interpreted by devices on the network, enabling seamless communication and interoperability. Examples of network protocols include TCP/IP, HTTP, FTP, and SMTP.

Bluetooth is an example of an unguided transmission medium because it uses wireless technology to transmit data. Unlike twisted pair, coaxial cable, and fiber optic, which rely on physical cables to transmit signals, Bluetooth uses radio waves to transmit data between devices. This makes Bluetooth a suitable choice for short-range communication between devices, such as connecting a smartphone to a wireless headset or transferring files between two laptops.

Bluetooth falls under supporting technologies because it is a wireless communication technology that supports the connection and exchange of data between devices. It is commonly used for connecting devices such as smartphones, tablets, and computers with peripherals like speakers, headphones, and keyboards. Bluetooth technology supports and enhances the functionality of various devices by providing a convenient and reliable wireless connection.

The transaction between MultiTV and Tonaton can be classified as e-business because it involves the use of electronic platforms, specifically the web platform, for advertising their used vehicles. E-business refers to conducting business activities electronically, including buying and selling products or services over the internet. In this case, MultiTV is using the web platform of Tonaton to advertise their vehicles, which aligns with the concept of e-business.

The initial cost being low is not an advantage of deploying a network. Deploying a network typically involves purchasing hardware, software, and setting up infrastructure, which can incur significant upfront costs. However, the advantages of deploying a network include sharing hardware, software, and information, which can lead to cost savings and improved efficiency in the long run.

The correct answer is 802.11. This is the IEEE standard for wireless local area networks (WLANs), commonly known as WiFi. It specifies the protocols and technologies used for wireless communication in the 2.4 GHz and 5 GHz frequency bands. This standard ensures compatibility and interoperability between different WiFi devices, allowing them to connect and communicate with each other seamlessly.

The World Wide Web is a solution for displaying, formatting, and accessing multimedia information over a network such as the Internet. It allows users to access websites, view and interact with multimedia content, and navigate through hyperlinks. Unlike telnet, FTP, and email, which serve different purposes such as remote login, file transfer, and electronic communication respectively, the World Wide Web specifically focuses on multimedia information dissemination.

The correct answer is "E-commence" because e-commerce refers to the buying and selling of goods and services over the internet, which includes both monetary transactions and non-monetary transactions such as online shopping, online banking, and online booking of services. Therefore, it is not limited to only monetary transactions on the internet.

FTP, or File Transfer Protocol, is a standard network protocol used to transfer data from one host to another host over a TCP-based network, such as the Internet. It allows users to upload and download files between their local system and a remote server. FTP is commonly used for website maintenance, software updates, and sharing large files. It provides a reliable and efficient method for transferring files over a network.

A ring topology allows only one-way flow of data across the media. In a ring network, each device is connected to exactly two other devices, forming a closed loop. Data is transmitted in one direction around the ring, passing through each device until it reaches its destination. This ensures that data flows in a single direction, preventing collisions and ensuring efficient communication.

The transmission medium does not convert signals back into usable information. Its main function is to carry the signals from the sender to the receiver without altering or converting them. The conversion of signals into usable information typically occurs at the receiving end, where the received signals are processed and interpreted by the appropriate devices or systems. Therefore, the given answer is false.

MAC Filtering is a wireless network security implementation where the device cannot connect if its physical address is not added to the trusted list. This means that only devices with specific MAC addresses are allowed to connect to the network, providing an additional layer of security by preventing unauthorized access. SSID refers to the network name, WEP and WPA are encryption protocols used to secure wireless networks.

The correct answer is "Both of A and B". This means that both the failure of one computer affecting the whole network and the disturbance of network activity when adding or removing computers are drawbacks of Ring Topology. Additionally, if the central hub fails, the entire network fails to operate, which is another drawback of this topology.
