Answer the questions you asked in the No. 0 week's homework
- Chapter One: What is the life cycle of a program?
- Write programs, preprocess, compile, assemble, link, run
- Chapter Two: The effect of unsigned numbers and number of twos complement on programming?
- Two different expressions, C and C + + support signed and unsigned numbers. Java only supports signed numbers
- Chapter Three: How to become Machine code in C program language?
- Pre-processing, compilation, and compilation become binary machine code, high-level language translated into assembly language and then become a binary language
- The fourth chapter: How is pipelining realized?
- Pipelining of program execution for processor implementation
- The fifth chapter: How to optimize the program?
- You can optimize your program by reducing process calls, eliminating unnecessary memory references, and more
- The sixth chapter: how to improve the time locality and spatial locality of the program
- According to the sequential execution of memory sequence, the program has good spatial locality, and the procedure of repeated reference to the same variable has good time locality.
- The seventh chapter: what is the link?
- Linking is the process of collecting and combining various pieces of code and data into a single file
- The eighth chapter: what is the consequence of the indeterminate behavior caused by the concurrent execution of the program?
- Cause program exceptions
- The Nineth chapter: How does virtual memory work?
- Virtual memory provides a consistent address space for each process, simplifying memory management
- The Tenth chapter: why is Standard I/O limited?
- Standard I/O and network files are incompatible with each other
- The 11th chapter: how does the Web server communicate?
- The Web server uses the HTTP protocol and its clients to communicate with each other
- The 12th chapter: What is concurrent programming?
- Program logic control flow overlaps in time
Bonus points Item
Lessons learned and deficiencies
- Harvest: Improve self-learning ability
- Insufficient: Super much insufficient, study of particularly tired, not interested.
Questionnaire Survey
- How long do you spend on average per week in this course?
- About 20 hours
- Do you improve your weekly learning efficiency?
- No
- Are you satisfied with your learning effect?
- General, not satisfied
- Will you continue at least one blog post at the end of the course? (If you can, I'll put your blog into a book when I graduate)
- Yes, but I can't write the academic stuff. 1
- What do you think the teacher of this class should continue to do?
- Cancel end of term
- What do you think the teacher of this class should stop doing?
- Forced
- What do you think the teacher of this course should start to do new things?
- You should focus on how to get students interested in your class, not what the students are thinking now. Take your blog as a weekly burden. You see the result is good: a semester down, students blog, their own batch of papers are very people have a sense of accomplishment. But... Burden
