III. Computer memory (From PowerPoint)
1. Computer memory is ___Binary________ (0 or 1) (on or off).
2. The ___byte______ is the standard unit of measurement.
3. A byte is composed of ___8 bits_______ (binary digits).
4. Typical units of measurement:
1 KB (kilobyte) = __1000_____ bytes
1 MB (megabyte) =1000 kilobytes or __1 million______ bytes
1 GB (gigabyte) =__1 billion______ megabytes or 1 billion bytes
IV. File management
1. Recognize that different programs have different file extensions.
2. Naming files - avoid the following _____characters_________ in naming files: @ * .
3. Saving files - know the difference between “save” and “save as”. “____save___” will
save the open document over the saved document while “___save as____” creates a new
document if you rename the document. ___save_____often so work will not be lost.
4. ________Exporting____ – converts a native format to a non-native file format to be used in
various software programs. In vector graphic programs, some file types may be
exported.
5. _______Merging Files______- in 3D graphics, bringing an outside file into an open file
(another name for this may be loading or replacing objects in the workspace).
6. ______Importing files_________- bringing a converted non-native format file into an open file.
