Hey Computer experts! What's a CRT and I have another question...? - Steve K I know a CRT is a computer monitor but I want to know what the exact words the CRT stand for? Plus, I also need to know if it's okay to leave your computer on all the time or is it better to shut it off. I know you save power by shutting it off but if I left it on all the time, does it hurt the computer in the long run by getting too hot or something?

Best Answer: CRT = Cathode Ray Tube, it's an old-style monitor (the heavy, long ones) that houses a gun in the back and shoots images from there onto the screen. Current models are often called "flat screens" because they aren't long in the back, but this is sometimes confusing because late model CRTs were sometimes called "flat screens" because the screens were flat (not bubbled out like earlier ones). It is fine to keep your computer on for long periods of time, however most Windows computers need a reboot now and then. Windows actually schedules maintenance in the middle of the night, which might never happen if you always turned it off before bed-- so you might argue it's better for the computer to leave it on. Assuming you leave it in an area that's at least moderately ventilated, not in a tightly closed cabinet or on a carpeted floor, you don't need to worry about overheating. - LordSam

Cathode Ray Tube the same as a TV's picture tube. Dont leave any system at on position while nobody is there - dxb78

It means Cathode Ray Tube. I know it sounds complicated but basically it is a monitor that is not as advanced as today and so it requires more space inside for the hardware. Since now a day we have LCD screens which are thinner and simpler, CRT are not seen as often. If you turn off your PC, it does not hurt anythings it just lets the PC rest so it wont get heated. Even with the fan, it helps to shut it down once in a while to sort of have your physical memory, or in easier words any tabs/programs you have open in your PC, be erased and the computer starts up fresh. personally, i prefer to just put my PC on hibernation mode so it may rest, but it quickly resumes to my profile when i want to. it also saves some energy. Once in a while i would shut it down so it would not damage internally or get a virus if you Have DSL or high-speed connection. If you have it on all the time, and have a high speed connection, you are more vulnerable to hackers, spy ware and viruses even with an anti virus program, etc. So really any damage to your PC would not be because of getting hot rather for just being connected tot eh Internet/to a LAN connection. - gingerstar04

Turning it off and on a lot isn't good for the hard drive. Instead of turning it off, you can put it in Standby or Hibernate. Try both of them out. When you log off, click the Standby button beside Turn Off button. It shuts off the computer halfway. To restart it, just jostle the mouse. It takes 5 seconds, and you are booted up and ready to go. Then, try Hibernate. To put the PC in Hibernate, you hold the Shift key as you click Standby. That's shuts the PC down more than Standby but less than Turn Off. Press the start button on the mini-tower like normal, and it takes about 15 seconds to boot up. Much faster than turning it off completely. Note: sometimes any slight banging in the house will cause the computer to come out of Standby mode (i.e. jostle mouse) so I use hibernate quite a bit. Good luck. - Brian Q

CRT = Cathode Ray Tube As far as leaving your computer running, you will probably see debate from both sides: energy conservationists vs the equipment conservationists. When you turn your machine on and off, the moving parts (especially the hard drive) in your computer are the most susceptible to damage as the warm up-cool-down cycles put extra strain on them. As far as energy usage, if you have your computer set to go into low power mode when you are not using it, then it takes hardly any energy to run your computer. There shouldn't be any heat buildup unless your fans are not working properly. I personally leave my computer running and let it go into stand-by mode when I'm not using it. But if I'm taking a trip or not going to be using my computer for a few days, then I will go ahead and shut it off. But I know people who only restart their machine after updates, and I know some who shut their machine down if they are going to be away from it for more than an hour. So it really comes down to your personal preference. - OpenSource

Cathode Ray Tube You can save energy by turning it off or you could use the time productively by running a distributed computing program like folding at home. - Brad J
