Drude – Lorentz Theory In 1900, Drude was first to explained metallic conduction on the basis of his free electron theory. In 1909, H.A. Lorentz modified this Drude model by applying Maxwell-Boltzmann statistics on the electron gas. This combined idea of Drude and Lorentz is known as Lorentz-Drude theory or classical free electron theory. This

A meteorite is a solid chunk of space junk that crashes to the planet’s surface. It is a natural object that made it through the atmosphere of Earth and down to the earth. Depending on where in the solar system they came from, meteorites can have varied compositions since they are formed of different kinds

The size, composition, speed, angle of entry, and location of the asteroid’s impact would all affect how it would affect Earth and how it would affect it. A small asteroid may harm the nearby area like a major explosion if it were to strike the Earth. The impact of the asteroid on a populated location

Astronomers have been concerned about the near-Earth asteroid Apophis because it could collide with Earth. When the asteroid was found in 2004, there was considerable worry that it might hit the Earth in 2029. Even if later observations ruled out a direct collision in 2029, there is still a remote chance that one will occur

A tiny, rocky or metallic object that circles the sun is called an asteroid. The asteroid belt, which spans the space between Mars and Jupiter’s orbits, is where the majority of asteroids are found. While others have orbits that bring them closer to Earth and other planets, some asteroids do. Asteroids can range in size

The Domain Name System (DNS) plays a key role in the Internet today as it allows applications to use fully qualified domain names (FQDN) instead of IPv4 or IPv6 addresses. Many tools allow to perform queries through DNS servers. For this exercise, we will use dig which is installed on most Unix systems. A typical

In contrast with OSI, the TCP/IP community did not spend a lot of effort defining a detailed reference model; in fact, the goals of the Internet architecture were only documented after TCP/IP reference model had been deployed. which defines the requirements for Internet hosts, mentions four different layers. Starting from the top, these are :

Our reference model is divided into five layers, as shown in the figure below. Starting from the bottom, the first layer is the Physical layer. Two communicating devices are linked through a physical medium. This physical medium is used to transfer an electrical or optical signal between two directly connected devices. Several types of physical
