8页1、Unit 2 Track 4-2-OL-5 In todays report, we look at a new technology called pervasive computing. Pervasive computing means putting tiny computers into everyday electronic appliances, such as toasters and microwaves. With pervasive computing, appliances can communicate with their users and with other appliances! Some companies now sell pervasive computing products like a “smart” toaster.
