Computers are now being used extensively in business. You can use
computers to maintain records, exchange information with people at distant
locations, and analyze daily transactions to generate reports. You can also
use computers to buy or sell products over the Internet.

Computers can analyze your sales for the day to determine the products
that have sold the most. As a result, you need not perform lengthy
calculations to manually analyze your sales data.

With advancements in technology, electronic devices such as bar code
scanners are now used in stores. Bar codes are printed black-and-white bars
that contain information about a product, such as its price and product ID.
The bar code scanner, which is connected to a computer, reads the bar code
and sends information to the computer.

The computer decodes the information and generates the invoice for the
customer. You do not have to manually enter information in a computer to
store sales information and generate the invoice. At the end of day, the
computer can automatically analyze your sales data.

Computers can also be used for online transactions, such as selling
products over the Internet. Customers can visit the Web sites of different
stores to purchase products. They can pay for these products over the
Internet, and the products can be delivered to their doorstep. Traders can
also use computers to check stock prices over the Internet. This helps them
organize and manage investments. Lesson 5 - CAREER
