Networking

Fiber-optic cabling has advantages over UTP cables, such as:
- It allows for longer distances due to the nature of the fiber-optic signals (C).
- It is less affected by external signals, making it more reliable (D).
Therefore, the correct answer is "C and D only."

Step 1: Understanding broadband internet services.
Broadband internet services are high-speed internet connections that allow continuous transmission of data and provide fast internet services over large geographical areas.
Step 2: Evaluating each option.
- Option 1: LAN (Local Area Network): LAN is a network limited to a small geographic area such as a single building. It is not typically used for broadband internet services. - Option 2: MAN (Metropolitan Area Network): MAN covers a larger area than LAN, but it is still confined to a city or large campus. It may offer broadband services but does not fit broadband internet services for individual connections. - Option 3: WAN (Wide Area Network): WAN covers large geographic areas, often spanning countries or continents. Cable-based broadband internet services often use WAN connections. - Option 4: PAN (Personal Area Network): PAN is used for connecting devices within a small area, typically a few meters. It does not apply to broadband internet services.
Step 3: Conclusion.
Cable-based broadband internet services typically operate over WAN, which is the correct answer.
Final Answer:

Step 1: Understanding networking devices.
Networking devices are hardware used to connect computers or other devices to the network and facilitate communication.
Step 2: Evaluate each option.
- Option (A) Gateway: A gateway is a device used to connect different networks and facilitate communication between them. It is a networking device. - Option (B) Repeater: A repeater is a networking device that amplifies or regenerates signals to extend the range of a network. - Option (C) MAN: A MAN (Metropolitan Area Network) is not a device but a type of network. - Option (D) Modem: A modem (modulator-demodulator) is a device that converts digital data from a computer into an analog signal for transmission over telephone lines and vice versa, making it a networking device.
Step 3: Conclusion.
The correct networking devices are Gateway and Modem.
Final Answer:

Step 1: Understanding the terms.
- STAR TOPOLOGY (A): This refers to a network topology where each device is connected to a central hub or node. - LAN (B): A Local Area Network (LAN) is a network of devices connected over a small geographical area, such as within a building. - HUB (C): A hub is a networking device used to connect multiple devices in a network, especially in a star topology. - VoIP (D): Voice over Internet Protocol (VoIP) is a technology used for voice communication over the internet.
Step 2: Match the items.
- (A) STAR TOPOLOGY matches with (I) Each communicating device is connected to a central node. - (B) LAN matches with (II) Networking device, as it refers to a network. - (C) HUB matches with (III) Protocol, as it is a networking device. - (D) VoIP matches with (IV) Type of network, as it is a communication protocol.
Step 3: Conclusion.
The correct matching is: (A) - (I), (B) - (II), (C) - (III), (D) - (IV).
Final Answer:

Step 1: Understanding WAN.
A WAN (Wide Area Network) is a telecommunications network that extends over a large geographical area, such as a city, country, or even globally.
Step 2: Evaluate each option.
- Option (1) PAN: A PAN (Personal Area Network) is a small network, usually limited to a small area like a room or personal workspace. - Option (2) WWW: The WWW (World Wide Web) is a system of interlinked hypertext documents but not a network. - Option (3) Ethernet: Ethernet is a protocol for local area networks (LANs), not a WAN. - Option (4) Internet: The Internet is the largest WAN that connects billions of devices globally.
Step 3: Conclusion.
The correct answer is the Internet, as it is the largest WAN connecting devices globally.
