What is Wireless LAN?

The Wireless LAN or Wireless Local Area are the most important and well - known in all wireless networks . To understand this type of network perfectly, it is important to first know what a LAN network is, without wireless, so we start there and then see the Wireless LAN in detail. Components of a Wireless LAN The physical architecture of WLAN is quite simple. The basic components of WLAN are typically: Wireless Access Point . Wireless network interface cards ( NICs ) You can use other components, such as wireless bridges or repeaters, to extend the reach of your network. There are two main problems or weaknesses, let's say so, that it has a WLAN: -Security. This is considered to be much more vulnerable than other networks, so it is necessary to take all possible measures to prevent anyone from accessing it. Hence, for example, what is encryption and the use of different keys and algorithms. -Speed. In the same way, there is still much better WLAN in this regar

what is system engineer?

The system engineering is a college career that deals with the design , programming, implementation and maintenance of systems . Unlike other branches of engineering , this discipline does not deal with tangible products (civil engineers, for example, build buildings), but with logical products. Therefore, systems engineering implies the use of mathematical notions that make it possible to specify the technological application of systems theories . It is an interdisciplinary science, which requires diverse knowledge to translate your designs into practical life. Systems engineering makes it possible to transform an operational need into a description of the performance parameters of a system, with its corresponding configuration. On the other hand, it enables the integration of the related technical parameters in such a way that the program and functional interfaces are compatible and the operation of the total system is guaranteed. When carrying out its work, the specialist in
