Computers are part of our everyday lives. They have an effect on

almost everything you do. When you buy groceries at a supermarket, a

computer is used with laser and barcodetechnology to scan the price of

each item and present a total. Barcoding items (clothes, food and books)

require a computer to generate the barcode labeland maintain the

inventory. Most television advertisements and many films use graphics

produced by a computer. In hospitals, besides terminals connected to the

hospital's main computer allow doctors to type in orders for blood test and

to schedule operations. Banks use computers to look after their customers'

money. In libraries and bookshops, computers can help you to find the book

you want as quickly as possible.
