2019-2020 20191327 "Introduction to information security professional," the second week of learning summary

1. learning content summary
Chapter One: Understanding the basic structure and system of the computer components. While understanding the history of the development of the computer; marvel from one room to the size of today's compact people; who first programmer what is the power of women as powerful.
Chapter XVIII: know what is the big O analysis, common to distinguish between the different orders of magnitude, also learned in mathematics computer is not a panacea, there are some special circumstances will occur error.
2. solve learning problems and resolve process
issues a : how to quickly find the code of the software error
resolution process: through Internet search, found different software have their own search methods, found some by thinning retrieval, making some simple the Demo, there is also some initial system automatically alerts.
Question two : Why the World Wide Web worldwide information sharing easier
resolution process: searching through the Internet, initially learned the simple reason that it is in a TCP / IP network protocol variety of different types, different sizes, the physical network located in different geographical locations the coupling as a whole. The specific reasons for the more esoteric needs a deeper understanding of the depth of learning again.
3. Learn sentiment
trying to learn about the code learning needs perseverance, we need to accumulate knowledge of all aspects of the need to constantly practice
4. learning progress
read the "wave of the summit" books
cumulative number of lines of code to play: about 70 rows (because the computer arrived and just getting started does not adapt, then will increase the number of lines)
