Very Short Question and Answers - Type of Network and Network Components

LAN stands for Local Area Network. It is used when two or more computers are connected within a small area, such as a room or office building.

The maximum range of a LAN can be up to 10 kilometers.

A common example of a MAN is a Cable Television Network.

The main purpose of a WAN is to connect two or more computers located at far distances using communication facilities.

A PAN typically includes devices such as a desktop or laptop computer, mobile phone, and handheld devices like PDAs or smartphones.

A server is a powerful computer that provides services and resources to other computers in a network.

A client is a computer that uses a network to access services and information from a server.

A NIC facilitates communication between different computers over a network and provides a unique physical address to each node.

A modem connects a computer to the Internet by converting digital signals to analog signals for transmission over phone lines.

A hub sends data received at one port to all other ports, while a switch sends data to the specific port assigned to the destination address.

A repeater regenerates and retransmits signals to extend the distance over which data can travel.

A router connects different networks and directs data packets between them, optimizing routes for efficient transmission.

A gateway is a point that connects two networks using different protocols, allowing for communication across them.

A bridge interconnects two LANs operating on the same protocol while filtering traffic based on source and destination addresses.

Essential components of a LAN include computers, network software, peripheral devices (like printers), and connection cables.

The typical range of a PAN is less than 10 meters, or about 30 feet.

You might find a MAN in urban settings, as it covers large areas like an entire city.

The two categories of modems are internal modems and external modems.

A switch increases network performance by sending data only to the correct port rather than all ports, which reduces unnecessary network traffic.

A WAN is commonly used for Internet access, connecting various devices and locations over large distances.
