Final answer:
LAN and WAN are two types of area networks. PAN (Personal Area Network) and LAN (Local Area Network) are two types of area networks, with PAN being used for personal device connection, and LAN for connecting devices in a building or nearby buildings. The correct answer is A.
Step-by-step explanation:
LAN and WAN are two types of area networks.
PAN (Personal Area Network) and LAN (Local Area Network) are two types of area networks, with PAN being used for personal device connection, and LAN for connecting devices in a building or nearby buildings.
The two types of area networks mentioned in the question are PAN (Personal Area Network) and LAN (Local Area Network). A PAN is designed for personal use within a range of a few meters, typically to connect a person's devices such as laptops, phones, tablets, and wearables. On the other hand, a LAN connects devices in a relatively close vicinity such as in a building or a group of buildings, allowing for resource sharing like printers and file servers within that area. WAN (Wide Area Network) is another type of network that covers a broad area, such as a city, country, or spans across global distances, connecting multiple LANs.
Two types of area networks (ANs) are Local Area Networks (LANs) and Wide Area Networks (WANs).
Local Area Networks (LANs):ANs are designed to connect computers and devices within a limited geographic area, such as a single building, office, or campus. They facilitate fast and efficient communication among connected devices, enabling resource sharing, data transfer, and collaborative work. LANs often use high-speed Ethernet or Wi-Fi technologies for connectivity and are commonly found in homes, businesses, and educational institutions. They provide a cost-effective solution for connecting devices in close proximity, ensuring quick data transfer and seamless communication.
Wide Area Networks (WANs): In contrast, WANs cover a broader geographic area, connecting LANs that are separated by large distances. WANs utilize various technologies, including public and private data networks, to link LANs across cities, countries, or even continents. The internet itself can be considered a vast WAN that interconnects networks globally. WANs are crucial for enabling communication and data exchange on a global scale, making them essential for large enterprises, multinational corporations, and organizations with geographically dispersed locations. They may employ technologies like leased lines, satellite links, or virtual private networks (VPNs) to establish connectivity over extended distances.
