3. WhatYou Need to Know
• A literal is a piece of data stored in memory, such as a
name, an address, or a phone number. It’s immutable,

7. WhatYou Need to Know
(continued)
• Platforms provide Software Development Kits (SDKs)
• SDKs consist of the all the resources necessary for
developing apps for the platform
• Integrated Development Environments (IDEs) are
programming tools used to make development easier
than using an SDK
• IDEs use SDKs as the “engine” to produce apps
