How to do a survey in blogger 2021
Hello guys I give you the warmest welcome to the Computer Science blog of group 459 of the National Preparatory School; I am sure it will be full of new knowledge and will contribute to your education.
A university student is not satisfied with someone transmitting knowledge to him/her, but he/she elaborates his/her own knowledge. A university student is nourished by his professors, by good bibliography, by the world around him, and he asks questions and wonders in order to find his own answers that satisfy him.
It is important that you discard the stereotype that Computer Science and Computing are only a multimedia tool that is applied in showy and sophisticated effects; since computing is a science that requires efficient professionals and a broad culture to be able to apply that knowledge, methods and techniques in the development of all disciplines as they are an indispensable complement.

SCHOOL CYCLE 2020 – 2021 GROUPS 458B, 459B, 460B, 461B, 462B, 463B, 467B, 470, 471B Week 17 (February 15 – 19, 2021) Unit 3. Computational Problem Solving Methodology Specific Objectives The student will: ● Will develop skills to acquire logical mathematical and algorithmic thinking in analyzing and solving computable problems by developing flowcharts, verifying the solution coded through a programming language. ● Develop attitudes such as concentration, patience, perseverance and creativity, necessary for programming. Conceptual contents 3.1Positioning: delimitation and scope of the computable problem 3.2 Analysis: definition of data and identification of the elements and resources required for the solution of the problem Zoom session * What is a problem? * Elements of analysis of a problem solution Activity 1 (Feedback in the next class) a) Steps of problem solving

FOR ALL THE STUDENTS OF THE SECONDARY SCHOOL SECTIONS: GROUPS 1° “A” DEAF, 1° “C” , 1° “D” AND 3° “A” – DEAF; , HIGH SCHOOL SECTION: 2ND SEMESTER – DEAF IN THE SUBJECT OF COMPUTER SCIENCE II AND SECTION: PREPARATORY UNAM INCORPORATED SYSTEM IN THE SUBJECT OF COMPUTER SCIENCE 4TH SEMESTER, WE ASK YOU THE FOLLOWING:
That when registering, they do it with their full name, not with their email username, since this will facilitate their correct identification on the platform and in the fulfillment and delivery of their activities. In the case that students are already registered (in their specific groups by level) but are with their user names, a video tutorial is attached, to make such change (modification).
IMPORTANT NOTE: STUDENTS WHO HAVE NOT YET HANDED IN THE PREVIOUS ACTIVITIES (THOSE THAT WERE REQUESTED BEFORE LEAVING ON VACATION) HAVE UNTIL WEDNESDAY, APRIL 22, SO THAT THESE ACTIVITIES DO NOT ACCUMULATE. PLEASE ORGANIZE YOUR WORK TIME PROPERLY WITH YOUR PARENTS, SO THAT YOU CAN TURN IN THESE ACTIVITIES IN A TIMELY MANNER.

➵Boot viruses. They are installed in the system boot sector or in the master boot record; they infect as soon as the computer is turned on, this prevents the operating system from booting.
➵Frame viruses. They use the macro programming language of a spreadsheet, word processor, and database application to spread every time such a file is started
➵ TSR viruses. they install themselves in the computer’s RAM while it is turned on. The computer must be turned off and restarted because it will continue to contaminate files and intercept operating system calls.
Polymorphic Viruses – Changes itself each time it spreads, so when trying to identify it by looking for a sequence of bytes that characterize it, it cannot be found. It changes its content randomly and makes it difficult to identify.
Spyware – Spyware is spyware that collects information from a computer. After obtaining the data, it transmits it to an external entity without the knowledge or consent of the computer owner.
