What is a modem?

Short for modulator - demodulator. A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.

What is clip art?

Clip art is a collection of pictures or images that can be imported into a document or another program. The images may be either raster graphics or vector graphics. Clip art galleries many contain anywhere from a few images to hundreds of thousands of images.

Clip art is typically organised into categories, such as people, objects, nature, etc., which is especially helpful when browsing through thousands of images. Most clip art images also have keywords associated with them. For example, a picture of a female teacher in a classroom may have the keywords "school," "teacher," "woman," "classroom," and "students" associated with it. Most clip art programs allow you to search for images based on these keywords.
