Collection of ideal essays on social studies. Collection of ideal social studies essays Getting ready for the exam computer science tasks

Hello, dear readers of the blog site. We continue to look, decide, remember what has already been forgotten. Today, on the queue of the Unified State Examination in Informatics 2017, I will try to sort out the assignments as much as possible, indicate what you need to know to successfully pass the Unified State Examination, and also share my impressions of the assignments. I remind you that the exam in mathematics and the level, and have already been sorted out, you can read about the demo versions of these subjects at the links.

I passed the exam a long time ago, there were few such tasks at the university, and far from all, so I ask you to understand and forgive me if you disagree with my assessments of complexity or necessity. But nevertheless, I will write an article, I hope it will be useful to someone, and someone will express their opinion in the comments.

USE in Informatics 2017, what you need to know

Generally speaking, judging by the demo version of the Unified State Examination in Informatics 2017, you need to know a lot, I hope the graduates know all this and it will not be somehow unusual for them to see such tasks.

You need to know the binary number system

Again, I won’t tie the list of necessary knowledge to task numbers, I’ll just give it as a list, so let’s go, I’ll try as it gets more complicated:

• Work with spreadsheets. Anyone who has used Excel will do this task without any problems.
• Know what number systems are. At least binary, octal, decimal and hexadecimal, although there may be number systems with any base, for example 3. And not only know, but also be able to translate from one number system to another. Moreover, to save time, it is better to understand which number system it will be easier and faster to translate into. For example, look at the first task, which contains a demo version of the Unified State Examination in Informatics 2017, there you can save a lot of time if you convert from binary to hexadecimal, and not convert everything to decimal.
• Know logic functions, truth tables for them and be able to work with truth tables for expressions consisting of several logical functions.
• Be able to work with graphs and tables. Moreover, sometimes they can be connected and it is necessary to establish the relationship between them.
• be able to represent text information in the form of discrete, that is, digital and know the units of information.
• To some extent, a continuation of the previous subparagraph. The ability to estimate the amount of memory needed to store one or another type of information (text, graphics, video, etc.)
• Know at least one programming language and be able to use it, how to write programs (more on that later), and understand what has already been compiled.
• Knowledge of computer networks, in particular, in the demo version there was a question about the TCP / IP protocol stack, perhaps there will be something else on the exam.
• Understand code written not in a programming language, but in Russian, if it’s not clear what I mean, see task 14 from the USE demo version.
• Be able to write programs in one of the programming languages ​​according to the task. And also understand someone else's code and find errors that were made when writing programs.

USE in Informatics 2017, impressions

After 5 years of studying computer science and programming at the university, I can’t say that the tasks seemed so easy. No, of course, everything is solvable, but you also need to know quite a lot. So the USE in Informatics 2017 is not very simple, it will be quite difficult to pass.

Important! If you cannot solve any task from part 2 given in the USE demo version, and do not even try to figure it out, being sure that you will have enough points for admission. even NOT go to university, to a specialty related to computer science and programming. Believe me, you can and will learn to program, but you will spend miles of nerves at the same time. So think very carefully about whether you need it, especially since there is a possibility that you will never learn to program. And after thinking, it’s better to give up programming anyway.

Many would not mind insuring themselves with ready-made answers to the USE-2017 in computer science. The exam is really not easy, you won’t be able to leave on intuition - you need to know. But do not rush to download answers from the first businessmen who come across the Web. First, let's figure out where the USE answers in computer science can come from; how realistic is it that anyone has them at all.

To whom and how do the USE answers get

There are three potential sources of prohibited information:

1. hackers break into mail or other servers of the Ministry of Education and Science or FIPI;
2. some of the employees of the Ministry and its departments violate the secret;
3. On the day of the exam, teachers or students promptly complete assignments from KIMs officially printed in the Far East and send them to the western regions, with which the difference between them can reach 6-8 hours.

Logic dictates that the first two sources are the most expensive, because we are talking about exclusive information that a graduate can have in advance. The third source for the graduate is less expensive (and let's say in advance that it is completely useless).

What sources of USE-2017 answers in computer science can be trusted

From East to West

The trick with the time difference between different regions is no longer a trick, but rather stupidity on the part of some graduates and laziness on the part of scammers who could not come up with a more tempting argument. The fact is that KIMs are different everywhere. Options developed a large number of, and if you don’t know which KIM options your region will get (and this is unknown to anyone except the elite), you don’t get answers, but a lottery with a very small chance of winning.

Of course, individual tasks may coincide, since they come from the same base, but it’s hardly worth spending time looking for answers and money for acquiring them (although sometimes answers are offered for free, so to speak, from the Unified State Examination solidarity).

Hackers and corrupt officials

Of course, no one on the Web introduces himself: “Hello, I am a hacker (or a corrupt official). I'm ready to make you a unique selling proposition that you can't refuse."

However, you can meet the following "tender" story.

Eleventh-graders lived and lived in one school, and before they were all tired of preparing for exams, they decided to collect all the money together and buy USE answers through one person who has the necessary connections. With the world on a thread - bought. Yes, it got too expensive. They decided to win back their money, but at the same time help the rest of the students, and began to sell the purchased answers to others. “And how not to buy something,” people think, “after all, we believe our own, relatives, the same schoolchildren.”

Very similar to epic. But it most likely is. Fraudsters try to allegedly speak the language of "customers", attract them with a folding legend about the origin of the answers, and successfully cash in on the fact that it is easy to disappear on the Internet at the right time.

Add to this observation that none of the previous exams that have already taken place this year revealed information leaks. Neither in the media nor on the Internet, no one en masse writes that the answers that were posted on the Web agreed with the tasks in the exam. Will this series of Rosobrnadzor's successes be interrupted in computer science? Doubtful.

Conclusion

There is only one conclusion: you cannot trust any sources of USE answers. There is more swindle in this matter than real help.

How to pass the USE-2017 in informatics without answers

In computer science KIMs there will be no very easy questions like “Define binary system reckoning”, etc. All 23 closed and 4 open tasks are aimed at testing your ability to analyze and apply knowledge. Without at least mediocre preparation for the exam, be prepared to retake. Alas, this year it will not work to retake the subject of choice and you will have to wait for the next year. On the other hand, you will have a whole year to study the subject perfectly and at a measured pace. And those who, because of the failure to pass computer science this year, are threatened by the army, will find benefit at least in the fact that after the service they will be able to enter the university on preferential terms.

If your interest in answers is dictated by simple self-doubt and the desire to insure, then everything is much simpler. You just don't need answers. You just need to repeat the basic things at night, sleep well and come to the exam with a fighting spirit.

Good luck to everyone on the exam!

WITH modern world technologies and realities of programming, development USE in Informatics has little in common. There are some basic points, but even if you understand tasks a little, this does not mean that you will eventually become a good developer. But there are a lot of areas where IT specialists are needed. You will not lose at all if you want to have a stable income above the average. In IT, you get it. Provided, of course, that you have the appropriate skills. And you can develop and grow here as much as you like, because the market is so huge that you can’t even imagine! And it is not limited only to our state. Work for any company from anywhere in the world! This is all very inspiring, so let the preparation for the exam in computer science be the first small step, after which years of self-development and improvement in this area will follow.

Structure

Part 1 contains 23 short answer tasks. This part contains tasks with a short answer, implying an independent formulation of a sequence of characters. Tasks check the material of all thematic blocks. 12 tasks are related to basic level, 10 tasks to an increased level of complexity, 1 task to a high level of complexity.

Part 2 contains 4 tasks, the first of which is of an increased level of complexity, the remaining 3 tasks are of a high level of complexity. The tasks of this part involve writing a detailed answer in an arbitrary form.

3 hours 55 minutes (235 minutes) are allotted to complete the examination paper. It is recommended to take 1.5 hours (90 minutes) to complete the tasks of Part 1. The rest of the time is recommended to be devoted to the tasks of part 2.

Explanations for grading assignments

Completion of each task of part 1 is estimated at 1 point. The task of part 1 is considered completed if the examiner gave the answer corresponding to the code of the correct answer. Completion of the tasks of part 2 is estimated from 0 to 4 points. The answers to the tasks of part 2 are checked and evaluated by experts. The maximum number of points that can be obtained for completing the tasks of part 2 is 12.
