Read the information and put 4 questions to your friends.
Web applications are rarely used, although XML files and other output may be passed to a computer for display. File systems with folders are typically absent as are SQL databases.
Software development requires use of a cross compiler, which runs on a computer but produces executable code for the target device. Debugging requires use of an in-circuit emulator, JTAG or SWD. Software developers often have access to the complete kernel (OS) source code.
Size of the storage memory and RAM can vary significantly. Some systems run in 16 KB of Flash and 4 KB of RAM with a CPU operating at 8MHz, other systems can rival contemporary computers. These space requirements lead to more work being done in C or embedded C++, instead of C++. Interpreted languages like BASIC and Java are not used.

Supper
- At what time do you usually have your supper?
- Well, I usually have my supper at seven o'clock.
- What do you have for supper.
- I eat either a slice of meat with some vegetables, or some meat salad, or a sausage sandwich, or some pudding and then I have a glass of tea with a piece of pie.
- Do you like your tea strong or weak?
- I don't have strong tea in the evening. And what about you?
- As for me, I eat almost nothing in the evening as I dine rather late.
- What does your supper consist of then?
- Oh, nothing substantial. It consists only of two cups of tea with milk and some toast or bread and butter. Sometimes I take either a cheese or a ham sandwich with my tea.
