Museo Louvre De Lens (Francia)




Concebido como una extensión del Louvre parisino en el departamento del Paso de Calais, este espacio expositivo se sitúa en una antigua zona minera, hoy en declive, para revitalizar su economía. No cuenta con una colección permanente en propiedad sino que cada cinco años recibe nuevas obras de similar calidad que sustituyen a las expuestas.
La propia estructura del edificio sorprende por su sencillez. Solo existe una planta a ras de suelo  y los materiales dominante son el cristal y el acero. Colores neutros y minimalismo para que todo el protagonismo lo adquieran los objetos expuestos. Además de una sala dedicada a exposiciones temporales, el espacio principal es la denominada Galería del Tiempo, un pabellón diáfano de 120 metros de longitud con paneles móviles para adaptarse a las necesidades de la exposición. En esta galería se cuenta la historia de la Humanidad de manera cronológica desde la Antigüedad hasta el siglo XIX. Un sorprende y fascinante recorrido por cinco mil años de civilización a través de esculturas, pinturas y diversos objetos decorativos.

Networking | Routing And Switching | Tutorial 4 | 2018


Welcome to my 4th new tutorial of the series of networking. In this blog you'll the content about network switches. You'll learn about how to make a communication successful and secure in the same network (LAN) by using STP. As Spanning tree protocol (STP) we used in multi-switched networks. Why we use this protocol in multi-switched network etc.

What is Switch? 

A switch is an intelligent device used to connect multiple devices within the same network. The intelligence of is that it requires Media Access Control (MAC) address for communication and doesn't allow broadcast.  Let's understand the whole thing by a little example, consider there is a network having 3 end devices name Device-A, Device-B,Device-C connected with each other respectively with the help of switch. When a Device-A sends data to Device-C so that data will only forwarded by switch to Device-C not to Device-B.

What is Media Access Control (MAC) address?

A Media Access Control (MAC) address is 48-bit unique physical address given to network interface controller (NIC) or network adapter, for communication within the same network which is given by its manufacturer. It is made up of hexadecimal numbers like a1:b1:cc:ac:2e:f1.

What is STP?


STP stands for Spanning tree protocol which is basically used in bridge and switches to prevent loops when you have a redundant links in the Ethernet networks. If the loop is present in the Ethernet network so the whole network will suffer because there will MAC instability in the MAC table,  duplicate frames generation and so on. Let's move to the video for further detail.
