Damn wish i could suck my own , need to stretch some more . <| sep |> Just say , No idea . I always tip . and let them struggle through it . <| sep |> Doesn ' t every database system need at least one human left to interact with it ? Doesn ' t a CEO kind of hold that position if it ' s the last one ? Should be a lead programmer or something but in case anyone gets me wrong that ' s what I ' m pointing out that we don ' t base this decision on logic . And it ' s a serious one according to most catastrophists . <| sep |> Originally with PCs many of the functions that we now take as standard built in stuff were optional features that could be added if you wanted to use them . This was because back then much of it was very expensive and you may not want to actually spend money on them if you did not use them . So if you wanted your computer to for example make sounds you bought a sound card that had all the electronics to make sounds and the connectors to connect device like speakers to them . Graphics were also a thing that did not use to be a standard feature . Your computer didn ' t have any graphic capability built in and when assembling it you just choose the type of expansion card that did what you wanted . If a two color text only output was enough for you you could go with that , if you wanted full graphics capability you could go with a more expensive option . Before to long simply graphics capability was something that was built in into the mainboards and you only needed a separate card for that if you wanted to do more complicated stuff . Eventually resolutions became higher and higher and different types of connectors became available and you needed to pick your video card based on that . Another thing that became popular was 3 D graphics . While any processor can make the necessary calculations to create 3 D images , the CPU in your computer is not really optimized for it . The CPU is an allrounder that can do everything . The chips used in modern graphics cards are sort of idiotsavants . They can only do few things but they can do them very well . The chips on the graphics cards optimized to make certain mathematical operations that you need for for example 3 D stuff . They can also be used to solve other problem that make use of the same sort of mathematical operations which is why for example a few years ago everyone was using graphic cards to mine bitcoins . Intel has recently started to put basic version of these graphic chips directly into their CPUs . These are actually rather powerful and unless you want to do some gaming or graphics processing you don ' t really need a graphics card anymore .
