Computer Networks: Types, Devices, and Protocols
A computer network consists of a set of computers and other devices connected physically or wirelessly, with the aim of sharing resources. There are networks with servers and peer-to-peer networks.
Network Types
- LAN (Local Area Network): A network within a limited area, like a home or office.
- WAN (Wide Area Network): A network spanning a large geographical area, like a city or country.
- NIC (Network Interface Card): A component that allows a computer to connect to a network.
LANs typically have two types

Electric Motor Components and Operation
The constitution of the electric motor comprises a casing, a fixed part or stator, and a rotating part or rotor:
Stator
The stator is a cylindrical ring composed of metal plates made and fitted under pressure into the motor housing. Its entire surface has available slots in which drivers are housed in the windings.
Rotor
The rotor rotates around the same axis as the stator. It consists of a cylinder formed by electrical sheets also pressed, with slots in its periphery.

Control Systems
A control system is a set of devices within a machine designed to manage and regulate the behavior of a specific variable. For a machine to operate automatically, a control system is essential.
Open Loop Control Systems
These systems operate for a predetermined time, irrespective of environmental changes. They function based on a preset value, known as the setpoint. Examples include dishwashers, washing machines, and basic radiators.
