Understanding Plastics: Types, Properties, and Recycling
Plastics are materials made of polymers consisting of long chains of atoms that contain carbon.
Types of Plastics According to Their Origin:
- Natural: Derived from vegetable or animal raw materials.
- Synthetic or Artificial: A compound derived from petroleum, natural gas, or coal.
Physical Properties of Plastics
These include hardness, elasticity, rigidity, toughness, and flexibility, which are specific properties of certain plastics and vary from each other.
Environmental Properties of Plastics
Most plastics

Understanding Computer Memory: RAM, CMOS, and BIOS
RAM (Random Access Memory)
RAM is a type of temporary or volatile memory where a computer stores data it is currently working on. When the computer is turned off, the contents of RAM are erased, and any unsaved information is lost. It is generally used as the main memory of a computer.
Dynamic RAM (DRAM)
DRAM requires constant refreshing to retain data in its cells. Memory cells consist of a capacitor and an electronic circuit. The circuit generates

Electricity Fundamentals
Matter is formed by atoms consisting of negatively charged particles (electrons) and positively charged particles (protons). Between these particles, there are forces of attraction or repulsion that generate a type of energy called electricity.
Material Classification by Electrical Behavior
According to the way materials behave when subjected to an electrical force, we classify them into:
- Conducting materials: These transmit electrical energy across their surface. We call this
Understanding Local Area Network Components and Structure
Elements of a Local Network
A local network requires several components, including:
File Server
This is typically a high-capacity computer that functions as the central repository for data and/or software applications on the network. It incorporates mass storage devices.
Workstations
These are the individual computers connected to the network. Computationally intensive tasks and the execution of application programs often occur at these stations.
Cabling
Connects the file server(s) and workstations. Also

Fundamentals of Electricity
Electric Charge: Substances are made of atoms, and atoms contain electrons, protons, and neutrons, which possess electric charge.
Electric Current: This consists of the movement of electric charges through a conducting material, such as copper or aluminum.
Generating Electric Current
Generator: A device that creates and maintains the voltage needed to produce and sustain an electric current.
Electrical Circuits: These are formed by a generator and several interconnected elements
