Types of Network Cables: Twisted Pair, Coaxial, Fiber Optic
Twisted Pair Cable
Twisted pair cable consists of two conductors, usually copper, each with its own plastic insulation, twisted together. One of the cables carries signals to the receiver, and the other is used as a signal ground reference.
In addition to the signal sent by the sender, interference and noise can affect both cables and create unwanted signals. If the cables are parallel, the effect of these unwanted signals is not the same in both due to their different positions relative to noise

Primary Networks and Subnetworks
Primary networks: Sets of wires connecting the substations with transformation substations.
Subnetworks: A set of cables connecting the substations of transformation with the rush of buildings.
Cogeneration
Cogeneration: Process of using the residual energy when producing electric or mechanical energy.
Cogeneration systems:
- Cogeneration using diesel cycle engine: Works like a standard diesel engine which has been coupled to an alternator to generate electricity.

Evolution of Computing and Cloud Computing FAQ
Historical Computing Trends
From 1960 to 1980, lower-cost minicomputers such as the DEC PDP 11 and VAX Series became popular among small businesses and on college campuses.
From 1970 to 1990, we saw widespread use of personal computers built with VLSI microprocessors. From 1980 to 2000, massive numbers of portable computers and pervasive devices appeared in both wired and wireless applications. Since 1990, the use of both High-Performance Computing (HPC) and High-Throughput Computing (HTC) systems

Hydraulic Systems: Principles, Components, and Applications
Hydraulic Systems: Advantages and Disadvantages
Hydraulic systems offer several advantages over pneumatic systems:
- Easy Speed Control: It is possible to regulate the flow of oil-water to control velocity.
- Transmission of Large Power: Hydraulic systems can transmit significant power.
- Position Control: Achieved thanks to the incompressibility of the fluid used.
- Reversibility of Drives: The fluid can move in either direction.
- System Protection: Possible through the use of safety valves.
- Start and Stop Under
Size Reduction: Methods, Applications, and Equipment
Size reduction, also known as comminution, is the process of reducing the particle size of materials to facilitate their handling, processing, or utilization. This process is fundamental in various industries, including mining, pharmaceuticals, agriculture, food, and chemical manufacturing. Size reduction enhances the surface area of a material, improves its flow properties, and prepares it for further processing, such as mixing, drying, or chemical reactions. Below is a detailed explanation of
