QI had two computers both connected to a wireless router. Yesterday I connected a third computer to the network and, although the connection goes through for this new computer, one of the original computers now says "Limited or no connectivity" and cannot connect to the Internet. Is it possible that the new computer is using up too much bandwidth and is therefore preventing the other computer from accessing the Internet?

QHi I'm interested in computer courses to study, today I spoke to someone from one of the unis I was interested in one of the courses were more about designing and the other practical and more technical fixing and support the system. I'm really interested in that. Its called computer enterprising. .But I want to apply to more but I get confused as every university calls the computer courses a different name. So i'm unsure if its software , or computer science , IT , IS with business. I think it could be IS with business what I'm interested in but I'm unsure. In some of the modules in the enterprise one has : information systems,computer programming ,data management , software testing , human computer interaction. developing internet applications supporting the systems kinda thingWhich computer course would include that sort of things? Its one of the practical and technical I want I'm not interested in designing. And can anyone tell me from this which computer courses is more like the one i described is it Information technology with business or something else? And is Computer science based on designing the applications? and not the more practical

QI have a great interest in computer and aircrafts, especially military aircrafts. I am planning to do computer engineering and be involved in the designing of military aircrafts (aircraft's computer).I need to know whether the US Air Force needs computer engineers and if yes, will a computer engineer be wearing uniform and do they have military ranks ?

QWhen is it time to purchase a new computer?Some people I have talked to told me its good to purchase a new computer every 2 years however that could be expensive for most people. I always thought every 4-5 years.What is your opinion on this?The computer I own is 11 months old?

QHi there. I was just wondering why its such a big thing these days to have a ridiculous amount of ram in a computer? People tell me that the more Ram you have in your computer the faster your computer will be. I always thought that it was the processor that controls the speed of a computer and not the Ram. I had 512MB of Ram in my laptop and I have now changed it to 2Gigs of Ram and I've seen no difference in performance what so ever. Could somebody please explain to me what does Ram does exactly?Thanks in advance

QI just figured out that my computer has this kind of trojan. I was running pretty much all of the Anti-virus things my computer has. The main one says there is nothing there and my Windows defender says I have two trojans so I'm not sure what to do. I'm thinking of buying or building a new one. Right now I have intel. Im not sure which is best like Dell, Miscrosoft, etc. I need a gaming computer which can also be used as a school work computer. Any ideas?

QI know I want to build my own computer for college. But the only brand that I know of that does build computers to your specification is Dell. However, I'm pretty sure that there is another top of the line brand that lets you build your own computer. So if you can have get some more options of brands for which I can choose that will be great.
