Case | The Farmer’s Wife
Ten years ago, Elizabeth and Scott MacDonald started The Farmer’s
Wife, a fruit and vegetable stand in Oquossoc, Maine. Their
business quickly grew to include fl owers, gourmet foods, home-baked
goods, wines, and seasonal items, including holiday decorations.
Elizabeth and Scott have spent so much time building their business
that they haven’t had time to research and purchase an updated
computer system. They need to buy a computer soon because
several of their suppliers are switching to all electronic ordering
systems. Also, customers who visit the area in the summer have
begun asking if The Farmer’s Wife has a Web site from which they
could order. Elizabeth and Scott ask you to research and
recommend a computer system that fi ts their needs. They want a system
that will grow with their business, but they have a limited budget to
start (approximately $1500). They ask you to help them decide what
to buy.
In this tutorial, you will learn about computers and their
components. You will learn about how data is represented, processed, and
stored. You will examine input and output devices, how information
is transmitted between computers, and ways to secure that
information. Finally, you will learn about system and application software,
and cloud computing.
