Data Storage

  • Floppy Disk: A thin, flexible plastic disk coated with magnetic material, historically used for data storage.
  • Hard Disk: A rigid, magnetic disk made of hard plastic or metal, used for long-term data storage.
  • CD-ROM: An optical disc that uses a laser to read data.
  • DVD: An optical disc with a higher storage capacity than a CD-ROM, also using a laser for data reading.
  • Magneto-Optical Disk: A disk that uses both magnetic and optical technologies for data storage.
  • Flash Memory:

Key IoT Protocols, Cloud Concepts, and Device Fundamentals

What is Modbus?

Modbus is an industrial communication protocol developed by Modicon (now Schneider Electric) in 1979 for programmable logic controllers (PLCs). It follows a master-slave architecture, where a master device initiates requests, and slave devices respond. Modbus operates over serial lines (RS-232, RS-485) and TCP/IP networks. It supports three modes:

  • RTU (Remote Terminal Unit): Binary encoding.
  • ASCII: Text encoding.
  • Modbus TCP: Ethernet-based communication.

It is widely used in SCADA systems,

Understanding Hierarchical Telephony Networks: Structure and Function

Understanding Telephony Network Hierarchy

The plants are tied together by bonds, which depending on the type of traffic that they are entered, you can classified as:

– Outbound Links. Course called output of the plant.

– Links of arrival. They’re going to get calls from other plants

– Bidirectional links. Are capable of acting both as output links Ecomo Arrival Due to a growing number of user lines, and therefore the number of plants, we again raised a problem of power interconnections to all users

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
