LAN stands for Local Area Network. A LAN is a network that connects computers and devices within a limited area, such as a home, office, or building. It allows for the sharing of resources and information between connected devices, such as printers, files, and internet connections. The term "local" refers to the limited geographical area that the network covers, distinguishing it from wide area networks (WANs) that cover larger areas, such as cities or countries. Therefore, the correct answer is "Local Area Network."

A computer in a network that acts as both a server and a client is referred to as a peer. In a peer-to-peer network, all computers have equal status and can both provide and request resources from other computers on the network. This allows for decentralized sharing of files, printers, and other resources without the need for a dedicated server.

WIFI is indeed an example of wireless networks. WIFI, short for Wireless Fidelity, is a technology that allows devices to connect to the internet or other networks without the need for physical cables. It uses radio waves to transmit data between devices, providing a wireless connection. Therefore, the statement "WIFI is an example of wireless networks" is correct.

In a star topology, all computers are connected to a central device called a hub. The hub acts as a central point of connection and allows the computers to communicate with each other. It receives data from one computer and transmits it to the intended recipient computer. Therefore, the statement that the device used in star topology to connect computers is called a hub is true.

A server is a computer that provides information in a network. It is designed to handle requests from clients and deliver the requested data or services. Servers are typically more powerful and have more resources compared to client computers. They are responsible for storing and managing data, hosting websites, running applications, and providing various network services. In a client-server architecture, clients send requests to the server, which processes them and sends back the requested information. Therefore, the correct answer is "Server."

The internet is an example of a Wide Area Network (WAN) because it connects a large number of computers and networks across the globe. It allows for communication and data transfer between different locations and is not limited to a specific geographic area. The internet is a public network that is accessible to anyone with an internet connection, making it a prime example of a WAN.

A computer that accesses information provided in a network is referred to as a client. A client computer connects to a server or a network and requests services or resources such as files, data, or applications. It relies on the server to provide the requested information or perform specific tasks. The client-server model is commonly used in networking, where the server acts as a central hub, and the clients connect to it to access shared resources.

A search engine is a website that allows users to search for specific content on the internet. It indexes web pages and other online content, making it easier for users to find relevant information by entering keywords or phrases. Search engines like Google, Bing, and Yahoo provide search results based on algorithms that consider factors such as relevance, popularity, and user behavior. They play a crucial role in helping users navigate the vast amount of information available on the internet.

A forum is a type of website where users can create, reply, and discuss various topics. It provides a platform for individuals to engage in conversations and share their opinions or knowledge on specific subjects. Users can start new threads on different topics and other users can respond by posting their own comments or thoughts. Forums are designed to facilitate discussions and foster a sense of community among users with shared interests or goals.

Networking is the correct answer because it refers to the study of the design, art, establishment, and topology of networks. It encompasses the understanding and implementation of various network components, protocols, and technologies to create and maintain effective communication systems. Networking involves the configuration, management, and troubleshooting of networks, ensuring their optimal performance and security. It also includes the study of network architecture, network protocols, network devices, and network administration.

In bus topology, all devices are connected to a single communication line. To prevent signals from reflecting back and causing interference, terminators are used to close the ends of the bus. These terminators absorb the signals and prevent them from bouncing back. Therefore, the statement that the device used in bus topology to close signals is a terminator is true.

The star topology is a type of network configuration where all devices are connected to a central device, such as a switch or hub. In a computer laboratory, it is common to use a star topology because it allows for easy management and troubleshooting of network connections. Each computer in the lab is connected to a central switch, which helps to ensure a reliable and efficient network. Therefore, the statement that the networking used in the computer laboratory is star topology is true.

The correct website address format for a Weebly account is "yourname.weebly.com". Weebly is a website builder platform that allows users to create their own websites. In this format, "yourname" represents the unique username chosen by the user, and "weebly.com" indicates that the website is hosted on the Weebly platform. This format ensures that the website is accessible to others and can be easily identified as a Weebly website.

A Metropolitan Area Network (MAN) is a type of network that covers a larger geographical area, typically a city or a metropolitan area. It connects multiple Local Area Networks (LANs) within the city, allowing for communication and data sharing between different locations. Unlike a Wide Area Network (WAN), which covers a much larger area such as multiple cities or countries, a MAN is specifically designed to serve a specific urban area. Therefore, a Metropolitan Area Network is the correct type of network that creates a citywide network.

A network is a group of two or more computers linked together to exchange information. This allows the computers to communicate with each other, share resources such as files and printers, and access the internet. By connecting computers in a network, users can easily share data and collaborate on projects, making communication and information sharing more efficient.

LAN (Local Area Network) is the correct answer because it refers to a network that is confined to a small geographical area, such as a home, office, or building. LANs are the basic building blocks of all types of networks as they provide the foundation for connecting devices within a limited area. MAN (Metropolitan Area Network) and WAN (Wide Area Network) are also types of networks, but they are larger in scale and encompass a broader geographical area than LANs.

Weebly.com is a correct answer because it is a website that offers free creation of websites. Users can easily create their own websites using Weebly's drag-and-drop website builder, without any coding knowledge required. Weebly provides various customizable templates, hosting services, and domain options, making it a popular choice for individuals and small businesses looking to create a website for free.

The type of cables used for bus topology is not UTP cable. Bus topology typically uses coaxial cables or Ethernet cables. UTP (Unshielded Twisted Pair) cables are commonly used in other network topologies such as star topology.

The LC computer laboratory is an example of a network using Ring topology. In a Ring topology, each device is connected to two other devices forming a closed loop. In the LC computer laboratory, the computers are connected in a ring-like structure where each computer is connected to two neighboring computers. This allows data to flow in a circular manner, passing through each computer until it reaches its destination.

In a Star Topology, UTP (Unshielded Twisted Pair) cable is commonly used. This type of cable consists of pairs of twisted wires that are not shielded, which makes it cost-effective and easy to install. UTP cables are capable of transmitting data over short to medium distances and are commonly used in Ethernet networks. They provide good resistance against electrical interference and are suitable for most office and home network setups. Coaxial cables, on the other hand, are not typically used in Star Topology networks, as they are more commonly used in cable television and broadband internet connections. Optical cables, also known as fiber optic cables, are used for long-distance and high-speed data transmission, but they are not commonly used in Star Topology networks.

Google.com, Yahoo.com, and Ask.com are all examples of search engines. These websites allow users to search for information on the internet by entering keywords or phrases. They then provide a list of relevant websites, documents, images, or other content that matches the user's search query. Facebook.com, on the other hand, is a social media platform and not a search engine.

However, the answer does not mention anything about traditional learning being the most effective, so that statement is not a known fact according to the given information.

Studying networking is necessary to establish an error-free network. By understanding the principles and concepts of networking, one can learn how to design, implement, and manage networks effectively. This knowledge helps in identifying and resolving network issues, ensuring smooth communication and data transfer between devices. Additionally, studying networking allows individuals to learn about network security, troubleshooting techniques, and best practices, which are essential for maintaining a reliable and secure network infrastructure.

Peer-to-peer architecture allows anyone to enter the network, as there is no central authority controlling access. This makes it easier for anyone to connect and participate in the network. However, this openness also makes it more vulnerable to security threats, as there is no centralized security control. Without a central authority, it becomes more challenging to enforce security measures and protect against malicious activities. Therefore, while it offers accessibility, it also poses higher risks in terms of security.

Computers can have different roles in a network. A server is a computer that provides services or resources to other computers in the network. It stores and manages data, files, and applications that can be accessed by clients. Clients are computers that request and use resources from the server. They rely on the server for services such as file sharing, printing, or email. Peers refer to computers that have equal status in a network and can communicate directly with each other. Peer-to-peer networks allow computers to share resources and communicate without a central server. Therefore, the correct answers are server, client, and peer.
