Questions and Answers of Introduction to Computing and Programming in Pytho

Look up Alan Kay, object-oriented programming, and the Dynabook on the Web. Alan is one of the inspirations for the media computation approach that we use in this book. Can you figure out what he has
As we said in the chapter, computer science is about people. Start your exploration of computer science by exploring the people who are computer scientists and influence computer science. As you do,
How can you encode a floating-point number in terms of bytes? Do a search on theWeb for “floating point.”You will find that there are different encodings of floating point numbers. Take a common
One of the powerful ideas in computer science is that encodings can be layered. Most of the encodings we’ve talked about so far (e.g., pixels in a picture, characters, floating point numbers) are
MicrosoftWord used to use an encoding of a word-processing document called “DOC.” Most recent versions of MicrosoftWord use a different encoding called “DOCX.” What’s the difference between
One bit can represent 0 or 1.With two bits you have four possible combinations 00, 01, 10, and 11. How many different combinations can you make with four bits or eight bits (one byte)? Each
Consider the representation for pictures described in Section 1.4, where each dot (pixel) in the picture is represented by three bytes, for the red, green, and blue components of the color at that
Text characters are encoded in different ways. The bottom level is always binary in bytes, but a different binary pattern can be used to represent different characters. Two of these encodings are
The 2013 Nobel Prize in Chemistry was in some sense a Nobel Prize given for work in computer science. What was the role of computers in that Nobel Prize?
Every profession uses computers today. Use aWeb browser and a search engine like Google to find sites that relate your field of study with computer science or computing or computation. For example,
