LAN stands for Local Area Network, which is a computer network that connects devices within a limited area.

• LAN is a type of network that is used to connect devices within a limited area such as a home, office, or school.

• It allows devices to communicate with each other and share resources such as printers and files.

• LAN networks are typically faster and more secure than wide area networks (WANs) because they are confined to a smaller area.

• Examples of LAN technologies include Et...read more

DC motors are electric motors that operate using direct current (DC) power sources.

• DC motors convert electrical energy into mechanical energy

• They have a rotating armature and a stationary field magnet

• Common types include brushed DC motors and brushless DC motors

• Used in various applications such as electric vehicles, robotics, and industrial machinery
