Machinery and Equipment Essentials
Machinery and Equipment
We live surrounded by machines and equipment: vehicles, watches, televisions, computers, washing machines, mobile phones, etc. From simple tools, like an opener, to more complex systems, like an industrial robot. Machines can be recognized by traits that distinguish them:
- Work with energy input: Machines and equipment require power supplies to function, either by connecting to a power source, battery, burning fuel, using air-operated pressure, or muscular effort.
- Transmit and
Green IT and Cloud Computing Essentials
Green IT Overview
(Green Computing/Technologies) refers to efficient computing resource use to minimize environmental impact, maximize economic viability, and ensure social duties. It identifies major energy consumers, environmental waste producers, promotes ecological software development, and computer recycling. Some technologies are classified as green for reducing energy consumption or CO2 emissions.
It is based on identifying technologies and energy-producing waste in computer product manufacturing,

Semiconductors
Semiconductors are neither conductors nor insulators. At room temperature, they are poor conductors but can conduct electricity with external power. Examples include silicon and germanium.
Doping
To improve conductivity, semiconductors undergo a process called doping. There are two types:
- P-Type: Dopants create “holes” where electrons are missing. Examples: Aluminum, boron, and gallium.
- N-Type: Dopants add extra electrons.

Computer Peripherals, Interfaces, and Technologies
1. Definition and Types of Peripherals
Peripherals are devices through which a computer communicates with the outside world. They also serve as storage systems, acting as auxiliary memory. Peripherals facilitate input/output (I/O) operations, complementing the CPU’s processing. They are classified into five main categories:
- Input Peripherals: Capture and send data to the computer for processing.
- Output Peripherals: Display or project information from the computer. These devices convert electrical impulses

Introduction to Electricity
Electricity is the movement of electrons through a conductor, such as a wire. This movement requires an energy source, like a generator.
Types of Current
Direct Current (DC)
In direct current, electrons flow continuously in one direction, from the negative to the positive terminal of a power source. Examples include batteries and flashlights.
Alternating Current (AC)
In alternating current, the flow of electrons changes direction periodically. This is the
