Wireless personal area networks and wireless wide area networks

 wireless local area networks, wireless metropolitan area networks, wireless personal area networks and wireless wide area networkseach with its own function. Below we discuss the different types of wireless networks and the various equipment and connections they require. Wireless LAN (WLAN) technology provides internet access within a building or a limited outdoor area. First used within offices and homes, WLAN technology is now also used in stores and restaurants. The use of home networks has greatly increased as the difference between computer engineering and computer science pandemic has forced office workers, students, teachers and others to work and study from home.

Most home network designs are simple. A modem connects to the cable or fiber from a local service provider. A wireless router is connected to the modem and receives the signal from the modem, which it then broadcasts using a wireless protocol, such as the 802.11 standards. Office networks are more complicated. Access points (APs) are mounted on the ceiling, with each broadcasting a wireless signal to the surrounding area. Multiple APs are required in large offices, each connecting to the office backbone network via a wired connection to a switch.

obstacles to becoming a professional programmer. For one, outside the industry, harmful stereotypes remain. Engineers are often seen as introverted, antisocial and (you guessed it) male. As a teenager who wasn’t any of those things, I was put off. And I know there are many others now who are just like I was then. So perhaps it’s not surprising that I didn’t want a job that, at first glance, appeared to isolate me from other people in some form of employed solitary confinement. So, it was with this thought in mind that I stepped away from engineering to instead embark on a career in marketing. Fortuitously my father happened to work in the same building as my new company, so before and after work I would spend time sitting in his office.  By observing him and his team, I quickly discovered that working in software development was not an isolating role, but rather a much more collaborative and sociable endeavour.  I  computer science vs computer engineering   then and there that I had to

Two founding signatories leave Architects Declare

 Over the past year, Zaha Hadid Architects and Foster + Partners, two of the 17 founding signatories of Architects Declare, have been criticised for working on aviation projects. Zaha Hadid Architects was criticised for designing Western Sydney International Airport, while Foster + Partners' decision to design an airport for a luxury resort in Saudi Arabia led Architects Climate Action Network, another group that advocates more radical climate action, to call on the studio to withdraw from the project or from Architects Declare. This division over working on airport projects led Foster + Partners to leave Architects Declare yesterday, with studio founder Norman Foster saying: "agriculture and aviation are not going to go away and they will both need the most sustainable buildings to serve them together with the architects who can most responsibly design them." Since its foundation, the UK branch of Architects Declare has gained over jobs with computer science degree whil
