Computers have changed the way that people operate within society. Rather than talking in person or on the telephone, people can communicate instantly via the Internet. People are not required to go to a store to shop or to the post office to mail bills and letters.

Computers have changed the way people view information. Previously, people wanted to store their information, such as work documents, and be able to access them again when the computer was turned back on. Now people can store documents, watch movies, read books, make telephone calls, get directions, access bank accounts, download and store music, and a multitude of other things all with a computer.
Computers have become so advanced that people carry them as cell phones, making pay phones obsolete. Personal information, including credit cards, bank records, personal pictures and contact information, is stored on computers and is accessible using almost any device with an Internet connection.
