How can I install software on External hard drive so that it works on any computer? As if I take it to one computer and plug the hard drive to the computer via USB and open the program from the external hard drive on that computer.
Thank you for your help.
Answer
Normal software normally gives problems when you use it on a different computer, because it usually keeps certain parts it needs on the computer you install it with, like for instance registry settings, even when you would install this software to an external hdd. Software that doesn't have this restriction is called portable software. Some newer software is designed to be portable, but there also may be software not indicated as portable that factually is portable just because it's self-contained, meaning it only needs it's own files and no installed extra's like the registry settings i mentioned. Some software can be made portable with a simple configuration-change like for instance choosing to keep it's initialization file in it's own installation map.
A nice collection of free portable software can be found here:

Below site also has some (i think) portable usable (although it's hard to be sure when it's not indicated to be portable that it wil work on all pc's because it may have hidden dependancies like standard windows dll's or registry settings) utilities like a cool system info utility:
http://www.mitec.cz/
A good example of selfcontained and therefore portable software is the utility photoview on mitec.cz. This utility has limited documentation but it can be used to explain the principle of selfcontained software and also why one shouldn't to quickly asume software is completely portable when not indicated to be portable. In the case of this utility i thought i read something about it being portable but i can't find it anymore, but given it's simplicity i think it's reasonable to assume it's portable, at least for the biggest part. Maybe the preferences may get lost when you use it on a different computer, not sure. When you download this utility and extract the zipfile you get basically 2 relevant files: photoview.exe and gdiplus.dll. Photoview.exe is the main programm-file, and gdiplus.dll is a library with functions used by photoview.exe. This gdiplus.dll file is normally also present in the c:\windows\system32 map so it normally could use that dll instead of the one kept in it's own map (when both are present the one in the map with the utility is used). But if you would happen to use this utility on a computer that hasn't gdiplus.dll it wouldn't work unless you keep that dll in the same map as photoview.exe.
PS: there is a slight difference between portable software and software that wil work on different computers. Take for instance the utility photoview i mentioned earlier. IF this utility would write some comfigurationsettings to the registry (i don't know) you wil loose those settings when you use it on a different computer, but that's not a big deal. However by doing so the utility would alter the host-computer, and portable software is supposed not to be doing that. Now is this potential registry alteration also no big deal but one should keep in mind that using a not explicitely portable utility on another computer can leave tracks on that other computer. Also using portable applications on computers that are not yours wil significantly enlarge the risk of a viral infection. 1 method to counter this is to use the portable software on a write-protected medium but then it of course can't safe any info like configuration settings.

How do you install speakers to a computer?
Isabella
My dad just bought some speakers from a friend, nothing came with them except a cord connecting them and a cord to connect it to the computer. The speakers are "Altec Lansing" my Monitor is called "View Sonic", and the computer part is a Dell. The Monitor used to be a Dell but it got shaky and we replaced it. There is a speaker on the computer but its really crappy. Does anyone know where the cord should be plugged into?
It doesn't seem as if there if a place for the jack on the back of the computer, does that mean theres somewhere else to put it?
Answer
On the back of your computer, you should see several small, round inputs. These inputs should be identical in every way to a typical headphone jack like you'd have on an iPod or other portable music player.
One of them should be colored GREEN. (There are usually at least three, one pink, one green, and one blue - however, more upscale computers may have more depending on the quality of the audio card).
The GREEN port is the speaker output.
Plug your speakers in there and you should be good to go!
ADDITIONAL INFO:
Can you send me the exact model of your Dell computer? Like, is it an Optiplex 280? If you let me know the exact model number, I can look up its inputs and I will send you exactly what you need.
