Class Summary 2-20-2014

Today was an open session meaning we talk about whatever comes up. I started off with talking about copyrighted pictures vs. free ones and where to find them. Here are a couple of site we browsed during class and a couple of additions:

We reviewed using by downloading a free image and then editing it. For more on it see

We had a question about what PhotoShop means when it tell you you have a disconnected picture. This is not only a PhotoShop issue. It could happen with Picassa and other similar programs. When you install the program it locates all your pictures and catalogs them with a thumbnail image of the original. When you open the program to browse your pictures it shows you thumbnails it created when you added the picture. If you then move the original picture to a different location then the thumbnail will display but the location the program expects to fine the original picture no longer contains it. If you know the new location you can tell the program or let the program search your hard drive to locate it. Best to organize you images withing the photo program instead of using File Manager.

Another question was about how to find a file when you do not know where you saved it. When you want to find something on the Web you open a browser and enter you request into the search engine. Finding a lost file on your computer is similar, but the "browser" you use is Windows explorer and the File Manager. Click the icon in the task bar (Windows 7 and 8 Desktop) the looks like a file folder. Or click the Start button to open the Start Menu (assumes Windows 8 users have gone to and installed it) and then click on Search for Files or Folders.

In the search box (right side under the ribbon with a magnifying glass) type the name of the file or a portion of the name, and as you type the search starts. It will display every file or folder containing what you typed.

Someone asked the difference between hibernating and sleeping. When the computer goes to sleep the monitor goes dark and the hard drive stops spinning. Everything else is still running. The computer looks like it is turned off, but it is not. So if it is on pure battery it will run the battery down and go off on its own. Hibernation is different. A copy of RAM is placed on the hard drive and a note made in the start up files of where it was placed. Then the computer does a complete shut down. When it is turned back on Windows recognizes that hibernation had taken place and restores RAM to its original state and opens right where you left off.

We covered a number of additional topics. Remind me of them and I will add to these notes.
