Logbook

Just to remind that the logbook is a very important component of the course and will be evaluated, together with the final exam they count 20% of the course grade.

You should record the logbook on a daily basis, with pages numbered and dated, about two main topics:

-Discussions and findings about projects, collectively or individually

-Answers to questions posted here in the class notes and other learning conclusions you found by doing activities related to this course.

The next logbook due date is Engin 103 Final Exam in May 2006.

Logbook questions:

1.- Why a binary representation is more suitable for the computer? What is the relationship between assembly code, programming language, and compiler?

2.- What is the minimum number of bits needed to write 127 in binary representation?

3.- Can fractional numbers be represented exactly in a binary system? Why computers use more bits (they went from 16, to 32, to now 64 bits)?
