Question

(a)LAN

(b)NIC

(c)www

(d) MAN

Answer 1

LAN stands for Local Area Network, which is a computer network that connects devices within a limited area, such as a home, office, or school: 

• Connections

  A LAN can be wired, wireless, or a mix of both. Ethernet is a specific method or protocol used in most wired LANs, but not all LANs use Ethernet. Wi-Fi is a form of wireless LAN. 

• Examples

  In a hospital, LANs connect medical devices like patient monitors and electronic health record (EHR) systems. 

• Setting up a LAN

  A network administrator can set up a LAN by connecting devices to a LAN switch using an Ethernet cable or by configuring a wireless access point (WAP) to broadcast a network service set identifier. 

• Definition

  A LAN is a collection of devices connected together in a single location, such as a home, office, or school. LANs can be small or large, ranging from a home network with one user to an enterprise network with thousands of users and devices. 

• Purpose

  A LAN's purpose is to connect devices in a specific location and enable them to share resources, such as files, printers, internet connections, and software applications. 

LAN is different from WAN, which stands for Wide Area Network, which covers a larger geographic distance and generally involves leased telecommunication circuits.
