(Thank you for the support of the book friend "Uh-huh-huh", bow!) In the new week, I ask you to give some support, the new book is not easy, and there are all kinds of requests for rolling all over the ground! ）

Tian Tian had already seen her lost video text, and because she was happy, she didn't pay much attention to Chen Mo's words, only to see her say with a look of surprise: "Master Chen is really amazing!" I actually found the text that was lost by the virus! ”

Chen Mo laughed dryly and said, "Actually, it's nothing...... Hehe......"

To tell the truth, Chen Mo has some contempt for the current university teachers, especially the university computer teachers, in his opinion, Tian Tian can't solve such an easy problem, this should definitely not be.

Tian Tian asked happily, "Master Chen, how did you do it?" I was very nervous just now, I didn't see your operation, can you explain it to me? ”

Chen Mo felt that it felt good to explain the problem about computers to a university computer teacher, so he nodded with a smile and said: "Okay, I'll just talk about my method, in fact, this method is very simple - the basic unit of the computer hard disk storage is the sector, these sectors are separated, this is like the paper book we read, divided into pages by page, after your computer is infected with a virus, it will automatically execute the text delete instruction, and delete the text you stored in the hard disk. If you want to find them, you have to distinguish the sectors on the hard disk of the computer, first of all, find the table of contents equivalent to the front of the paper book, and roughly calculate how many sectors the text you want to find is stored between the sectors......"

Chen Mo saw Tian Tian's eyes widening the more he listened, and his face was fascinated, he couldn't help but stop, and asked curiously, "Sister Tian, why do you have this expression?" ”

Tian Tian came back to her senses at this time, only to see her sneering: "Oh, I just think it's very fresh, to be honest, it's the first time I've heard these contents!" Master Chen, go on. ”

Chen Mo once again slandered the level of today's university computer teachers in his heart, and then continued: "After roughly estimating the range of sectors where Wen Jiàn may be stored, you can get them back by removing these 'delete' signs that Wen Jiàn was marked." ”

Tian Tian couldn't help but widen his eyes when he heard this: "That's okay?" ”

Chen Mo said depressedly: "Otherwise, how complicated do you think?" ”

Tian Tian blinked his eyes and said, "But...... But those texts have been deleted, it's like the number of pages in a diary has been torn off and burned, how can you find the content on it? ”

Chen Mo sighed in his heart when he heard this, and then explained: "Although the sector division of the computer hard disk is very similar to that of a paper book, the two methods for destroying the above content are not the same, once the pages of the paper book are torn off and burned, the content on it is impossible to retrieve, but the computer hard disk can, this problem involves the storage and deletion principle of the computer hard disk, we store the data in the computer hard disk, in fact, it is equivalent to arranging some symbols in it, according to the base system of the computer program, These symbols are all represented by the numbers 0 and 1, under normal circumstances, we want to delete a text, just right-click, and then click on the 'delete' column, the vast majority of people think that this is even if the text is deleted, in fact, they are just marked' When the new text is stored on the hard disk, the area where the text that has been marked 'deleted' will be overwritten, so that we really can't find them, but before the new text is stored in the computer, we can remove the 'delete' symbol that they are marked, so that we can find them. ”

Chen Mo paused when he said this, and then continued: "Your computer was just bought, and most of the storage disk in it should be free, I found those texts that were automatically deleted by the virus, and then removed the 'delete' mark marked on them, so that the computer will recognize the storage of these texts, and they will also appear in the computer hard disk." ”

When Tian Tian heard this, she finally understood the principle thoroughly, and she couldn't help but sigh: "So that's the case...... Master Chen, you're amazing! I know so much! ”

Chen Mo said modestly: "Where is it, I just usually like to delve into computer hardware knowledge, and I am very clear about the working methods and principles of each computer hardware, Sister Tian, since you are a university computer teacher, have you not been exposed to this knowledge?" ”

Tian Tian said a little embarrassed: "The computer science department of the university mainly teaches students the knowledge of software programming, and the rest is gone, so we teachers only learn the knowledge of software programming, and we don't need to know everything...... By the way, Master Chen, are you really just a computer repairer? ”

Chen Moxin said: No wonder it's like this, this is really exam-oriented education! Students learn knowledge in order to cope with the exam, and the teachers teach knowledge so that students can get the pass during the exam, so that most of the students are very rigid when they study, and they can cope with the exam, but the practical application is not good, this is also the so-called high score and low ability, Tian Tian can become a university computer teacher, and she should also be admitted to the exam, and it is not surprising that her actual operation is not good.

Chen Mo thought of this and nodded: "Yes, I just can't say that, in fact, I just work as a small worker in this shop, and it's only because I'm more interested in computers that I learned and mastered this knowledge." ”

Tian Tian couldn't help but sigh: "Your computer technology is much better than mine, at least in terms of hardware, I am 108,000 miles behind you." ”

Chen Mo smiled modestly, and then changed the topic and said, "Since Wen Jiàn has been recovered, let's take a look at whether Wen Jiàn is intact, if something really goes wrong, it won't be good." ”

Chen Mo was worried about the 50,000 yuan, but Tian Tian thought he was worried about himself, so she smiled and nodded, "Well, let's take a look at Wen Jiàn first." ”

Chen Mo clicked the play button, and then the promotional video created by Tian Tian appeared on the computer monitor.

Although Chen Mo doesn't understand video creation technology, he can see at a glance that the picture of this video is a little rough, and the creativity is not very good, and overall it can only be regarded as okay.

Tian Tian had long regarded Chen Mo as an omnipotent computer master, and she asked while watching, "Master Chen, what do you think of this video?" Is there anything that needs to be improved? ”

Chen Moxin said: Can I say that this video needs to be recreated?
