Technology Tips: Shut down your computer!

Today's Technology Tips comes to you for all users...not just Teachers...but students Too!

One of the common questions people ask with their computers...do I need to shut down?

-Because of hibernate commands and stand by modes... people think they don't need to turn their computer off.

However, please read this:

From a software perspective, an operating system and the programs you run on it tend to accumulate all sorts of cruft over extended periods of use – temporary files, disk caches, page files, open file descriptors, pipes, sockets, zombie processes, memory leaks, etc. etc. etc. All that stuff can slow down the computer, but it all goes away when you shut down or restart the system. So shutting down your computer every once in a while – and I do mean actually shutting down, not just hibernating or putting it to sleep – can give it a “fresh start” of sorts and make it seem nice and zippy again.

However, different computers and OS’s are not all equally affected by this phenomenon. Generally, a computer with a lot of RAM can go for much longer than a computer with only a little RAM. A server, on which you just start up a few programs and then let them work, will be fine for much longer than a desktop computer, where you’re constantly opening and closing different programs and doing different things with them. Plus, server operating systems are optimized for long-term use. It’s also been said that Linux and Mac OS tend to run for longer than Windows systems, although in my experience that mostly depends on what programs you use on them, and not so much on any differences between the kernels of the operating systems themselves.

That came from an article LINKED HERE.

Think of it this way...computers are nothing but machinery.  All machinery breaks down eventually.  If you run something continually, all the time, never shutting it off, you are shortening it's useful lifespan.

In addition, with Windows computers (like our school machines)...Microsoft often releases updates that are installed when the computer shuts down.

Also, for student machines...the large majority of students take their netbooks home every day.  The computer should be shut off during this travel time.  If it is on, the hard drive...which is a physical piece of machinery, is still running.  

This is what a Hard Drive looks like.

I can't tell you how many student machines are brought to me to work on that are not powered off.  Even last summer, when I went to install new programs on all the existing machines... over half of the students machines were not shut off.

So, do yourself a favor, and give your computer a break...it'll appreciate it.  At the end of the day...Shut Down!
