What is a Computer?
A computer (from the Latin computare, meaning “to estimate”) is an electronic device that processes data to produce useful information. It consists of integrated circuits and components that execute instructions with speed and accuracy, based on user input or automated programs. This process, known as programming, enables a wide range of practical applications.
Computers require both software (instructions) and specific data (input) to generate output (processed information).

1. Alternative ISPs in Areas Without Coverage
In areas where alternative ISP networks lack access to Telefónica’s ADSL infrastructure, two main options exist. The speed of these options reflects the market conditions at the time of Telefónica’s recruitment.
ADSL Resold (Almost Obsolete)
This service, based on GigADSL, was used by alternative operators in the early days of ADSL. The alternative ISP rents all connection layers from Telefónica, including ATM, IP address, and transport network to a

Leveling Struts
Struts are telescopic and are used to ensure the vertical (plumb) and temporary bracing of the walls. They attach to the walls and the horizontal plates, ensuring the successful implementation of the panel seams.
Modular Coordination
This consists of a series of steps in line with the chosen measurement system and form of coupling parts, tolerances, and errors.

Control Devices
Definition
A control device is a key component of a charge control circuit, facilitating communication between the user’s control circuit and the machine.
Types of Control Devices
- Switches: Multi-position switches used to intervene in the control of a circuit.
- Pilot Lights: Indicate a command action.
Buttons and Switches: Symbols
Buttons, used for maneuvering in control circuits, consist of two parts:
- Control Device: The part of the button that the operator interacts with.
- Contacts: Responsible
Injection Pump Function, Types, and Operation
Injection Pump Function
What is the function of an injection pump?
Its function is to send oil to the injectors at the right time, at the correct pressure, and perfectly dosed for each engine’s working condition. Regarding types of mechanical pumps, they can be linear or rotary. Many brands exist, but Bosch and Lucas are among the most representative.
