Adding to Your System
Just as there are all sorts of application programs you can get for your computer, there are
dozens of peripheral devices that can make your computer more useful.
The following sections
give you an idea of typical system configurations for school, home, and office use.
Different Configurations
Read about the configuration that best applies to you. If you want to know more about any of
the peripheral devices mentioned, you'll find sections later in this chapter that describe each
peripheral device in detail.
School Configuration
A typical school configuration might consist of an Apple IIe, a monitor, a disk drive, and a
mouse.
A color monitor is ideal for schools because most educational software uses color to engage and
hold students' attention, but it's not a requirement software will run just fine on a
television set or a monochrome monitor.
For many applications, a single disk drive is inadequate because you spend a lot of time
exchanging your program disk for your data disk, but it's not a problem with most educational
software because students can use the educational programs for drill and practice without
saving their work on a disk.
While it's not a requirement for most educational software, a mouse is a desirable peripheral
device for school systems because mouse-based programs are easier to learn and more intuitive
than keyboard-based programs.
