Computer ads come in two types, namely Classified Computer Text Ads and Classified Computer Display Ads. Classified text ads are simple text ads, and they are the cheapest. These ads are charged on the basis of number of words, number of lines or number of characters used. Classified display ads include richer formatting and images, and these ads are charged on the basis of space occupied. If you wish to include a photo of a computer in your newspaper advertisement, you will need to book a Classified Computer Display Ad. Hope this helps!
