A Timeline of Robot History and Development
History of Robots
Research in this area began in the 1950s, promising rapid progress. However, it stalled due to seemingly simple problems. In 1960, a robot could see a tower of cubes and copy it, but the lack of common sense led it to build the tower from the top down, releasing the blocks into the air. David Freedman, recognized as one of the best U.S. science writers, documented in his book Brain Makers two major projects under development in the area of artificial intelligence.

Key Features of the Physical Layer
The physical layer is responsible for all physical, electrical, functional, and procedural aspects of each network element. It transforms bit streams (link layer) into signals that can be transported by the physical medium and vice versa. This is necessary for data transmission between two hosts through a physical medium.
This includes cabling, connectors, and cables linking network devices, the devices themselves working at the level of electrical impulses and signals,

Operating Principle of Diesel Engines
A diesel engine works by the ignition of fuel injected into a combustion chamber containing air at a temperature above the fuel’s autoignition temperature.
Advantages and Disadvantages of Diesel Engines
The main advantage of diesel engines compared to gasoline engines is their low fuel consumption. The primary disadvantages of these engines are their higher initial price and maintenance costs.
Applications of Diesel Engines
Diesel engines are used in various applications,

Supercomputers
High-performance computers used for specific purposes that require great computing power (e.g., nuclear test simulation, simulation of natural disasters, scientific investigation). They consist of thousands of processor cores, take up large spaces, and consume significant amounts of power.
Top500 is a project responsible for developing a ranking of the 500 most powerful supercomputers in the world. Currently, the first place belongs to Fugaku (Japan)

Types of Network
- PAN (Personal Area Network)
- LAN (Local Area Network)
- MAN (Metropolitan Area Network)
- WAN (Wide Area Network)
What is an IP Address?
It is a numerical set used to identify each computer connected to a network.
Static IP Address vs. Dynamic IP Address
A static IP address is one that has a fixed numerical address assigned by the Internet service provider. A dynamic IP address provides a different numeric set to your computer each time it is connected to the network.
Types of Internet Connection
- Wired
- Optical

Short Circuit
A short circuit is the union of two wires or parts of an electrical circuit with a potential difference or voltage to each other, without any electrical impedance between them.
Cutouts
Cutouts are no more than a section of wire thinner than normal conductors, placed at the entrance of the circuit for protection. When the current increases due to a short circuit, this part heats up and, therefore, is the first to melt.
Differential
