This week, the focus shifts to software licensing and concepts of free software, before moving on to more specific topics such as software development, software testing, and software piracy. The material for this week's video has already been sent to the editor for editing, and a telegram has been set up for discussion of course materials.
00:10:00 This video is about computer topics, specifically Professor Renato da Costa's classes on computer security and malware. In the first part of the lesson, Professor da Costa discusses the different types of malware and how they can be used. In the second part, he discusses spyware and how it can be used to monitor a person's online activities. The last part of the lesson is about privacy and how social media can affect it.
00:15:00 The video discusses the different types of malware and how to identify a legitimate spoiler program. The speaker notes that, as an example, a legitimate spoiler program for a child's phone might be installed with the child's consent.
00:20:00 The video discusses the use of keyboard spies, which are programs that capture everything typed by the user, and some sites feeling harmed by this practice of spy programs. It also discusses the development of virtual keyboard technology to prevent users from logging in this way, and the use of screenloggers to capture screens. The video then shows how a keyboard spy works on Windows, and how a screenlogger captures screens as you type. The screenlogger also records audio, and can show the user what was captured on the screen. The screenlogger is considered a kind of spy program, because it is often used to spread political propaganda.
00:25:00 In this video, Professor Renato da Costa discusses the different types of computer viruses. He explains that a spam message is a message that is unwanted, and a boato is a rumor. He also discusses the Root's virus, which is a virus that is designed to exploit someone's online security.
00:30:00 This video discusses various computer topics, including how a company airline participates in the best hotel celebrations, and how Leonardo DiCaprio's character in the movie "Prenda-me" has several professions, including pilot and doctor, that are alternated throughout the film. One computer program that exploits vulnerabilities and causes slowdowns is the "time bomb." This virus is programmed to go off on Valentine's Day, and reminds viewers of the Chernobyl disaster with the warning that "this is just the beginning." Other viruses that stay latent all year are described, along with an example of a malicious program that uses them to achieve its goals. The next topic discussed is a malware type known as a "bomb lógica." This code is injected into a system to cause it to crash, and is sometimes used to take down a user's computer. The video concludes with a warning about the dangers of bomb lógica codes, and provides an example of how they might be used.
00:35:00 In this video, Professor Renato da Costa discusses the different types of malware and how they can affect a computer. He also discusses how a Spider virus can propagate without being explicitly executed. This is a relevant topic, as some people still believe that downloading and installing programs from untrustworthy sources is a safe practice.
00:40:00 In this video, Professor Renato da Costa discusses the different types of computer viruses, and how to protect yourself from them. He also discusses the Spider virus, and how to identify and avoid it. Finally, he discusses the importance of having a security guide, and how to use it to protect yourself from viruses.
00:45:00 The video discusses the different types of spyware and spyware programs, and how they can be used to invade and spy on a computer system. One particular question on the test was incorrect, and the student was penalized for arguing with the professor. The video concludes with a brief discussion of the different types of spyware and spyware programs and their respective purposes.
00:50:00 In this video, Professor Renato da Costa discusses the concept of backdoors and how they can be used to invade someone's computer. He also mentions programs that are very similar to spiders, but have different purposes. Finally, he talks about how an administrator should use sniffers to monitor the traffic on their network.
00:55:00 The video discusses ways that technology can be used for illegitimate purposes, such as Jennifer being used to track down someone illegally. It also recalls the engineering social attack, which is a type of attack designed to obtain data for the purpose of fraud. Spam, which is a message that is unwanted, can also be used as an attack. The time bomb virus is a particularly malicious code that infects a browser, and it is worth the people installing it to be aware. The Jack virus infects the browser, and as a result, the person who is infected may experience problems with their online presence. After discussing the idea, it is rejected by the audience. However, the presenter believes that it could be viable to persuade someone at Rosen Val Marketing to sponsor the idea in order to gain 50 cents for every person who clicks on the coruja logo.

01:00:00 - 02:00:00

In the video, Professor Renato da Costa discusses the concept of "hijacker." He explains that hijackers are people who exploit a user's computer by opening unwanted pages and stealing money. The video also covers the history of the "Cavalo de Tróia" story, which teaches children about the importance of compromise and communication. Professor Costa recommends that people learn how to program and adjust settings on their computers in order to avoid becoming a victim of a hijacker.

01:00:00 In the video, Professor Renato da Costa discusses the concept of "hijacker." He explains that hijackers are people who exploit a user's computer by opening unwanted pages and stealing money. The video also covers the history of the "Cavalo de Tróia" story, which teaches children about the importance of compromise and communication. Professor Costa recommends that people learn how to program and adjust settings on their computers in order to avoid becoming a victim of a hijacker.
01:05:00 In this video, Professor Renato da Costa discusses the history and meaning of the term "Cavalo de Tróia," and discusses some potential dangers of using such a program. He also discusses different types of Trojan horses, and how to identify and avoid them.
01:10:00 This video discusses different types of computer viruses, including Trojan horses. The video explains that a Trojan horse is a type of virus that is designed to do harm to a computer. Backdoors are a type of Trojan horse that allow remote access to a computer. Spyware is another type of virus that collects sensitive information and sends it to third parties. Finally, the video discusses the Delta virus, which is a type of backdoor that allows unauthorized access to a computer.
01:15:00 This video covers the different types of malware, and how to identify and avoid Backdoors. It also covers the dangers of spam and how to protect yourself from it.
01:20:00 The video discusses different types of malicious code, including techniques like data fusion and polymorphism. These are created by attackers to make it more difficult for antivirus software to detect and prevent attacks. One type of malicious code is called a virus polimorphic. It exists when a virus changes its form to evade detection. Another type of malicious code is called a backdoor. It allows an attacker to return. 4 out of 5 items are true. Backdoor malware is designed to stay hidden, and can be installed on the system's kernel. It is difficult to remove. Damage caused by a virus of computer can often require formatting and reinstallation of the computer's operating system.
01:25:00 The video discusses the concept of "malicious software" and how it can be used to attack a computer system without the user's knowledge. It goes on to discuss the various types of malware and their methods of attack. The video finishes with a discussion of "highjack" malware, which is known for its ability to hijack a user's browser and steal their online money.
01:30:00 The video discusses various computer-related topics, including the idea of "click-jacking" – where someone is directly rewarded for clicking on a malicious link, rather than through the regular website rewards system. It also covers the different types of malware, and how users can protect themselves from them. One of the key points made in the video is that anyone studying for a computer science or programming competition should be aware of the page on the Cartilha website that compares different types of malware. This page is available at www.cartilha.br, and the PDF book version can be downloaded from that site. Click-jacking, malware types, and computer viruses are all discussed in more detail, along with the different ways in which they can be spread. The video finishes with a brief discussion of computer "pest management."
01:35:00 The three technical concepts below correspond to one of the three possible ways a virus can infect a computer: through the inclusion of copies of itself in other programs, through the inclusion of copies of itself in other files, or by directly executing copies of itself or by exploiting vulnerabilities in existing programs. The third concept, backdoor, refers to a virus that creates copies of itself in other locations in order to execute malicious actions. The candidate answer is "Backdoor."
01:40:00 In this video, Professor Renato da Costa discusses the differences between malware and viruses. He also explains the concepts of Backdoor and Fishing, which are two of the less dangerous types of malware. Finally, he provides a brief overview of cybersecurity issues. If you're studying information technology, it's important to use your good sense when trying to answer this question: which is the answer to item 3? Most people would say that it's not malware, but instead it's a type of fishing technique. Engenharia is the term for the practice of designing techniques to mislead or deceive. The third item is a question that has been difficult for those studying information technology to answer. It's between A and B. I know that for someone who is studying it can be difficult to identify the man as a virus because the man is a specific type of malware that is different from a virus. However, the context of the question is more expansive. It's a context of a malicious program, such as a virus of a particular kind, that creates copies or infects other computers or networks. The idea of the man spreading or replicating itself to carry out more selfish actions is what might be considered in item 3. The practice of spamming
01:45:00 In this video, Professor Renato da Costa discusses the dangers of flooding and how it can be caused by congestion. He also discusses the phenomenon of fluide, which is an attack based on water flooding. Finally, he discusses how software can be improved to prevent such attacks.

02:05:00 This video features Professor Renato da Costa discussing various topics related to technology. Among the topics discussed are mobile technology, online security, and computer viruses.
02:10:00 In this video, Professor Renato da Costa discusses software concepts, specifically software vs. hardware. He explains that software is intangible and can't be touched, while hardware is tangible and can be touched. He also discusses how software can be classified as either software programs or software instructions, and how it can be tested on the exam.
02:15:00 In this video, Professor Renato da Costa discusses the different components of a computer hardware and software. He states that the hardware, or physical parts of the computer, is perfect if it has the software to run on it. The software is what the programs running on the computer are made of, and the instructions that are passed to the computer through programs. The third item is false, as the concepts of software and hardware are swapped.
02:20:00 This video discusses the different components of a computer, and explains that, while hardware (the physical parts of the computer) is independent, software (the logical parts of the computer) needs both hardware and software to function. The main point of the video is to remind people that a computer is composed of two parts, hardware (the physical parts) and software (the logical parts). The hardware part (e.g. the CPU) needs software to function, and the software part (e.g. the programs) needs hardware to run. Item 3 is incorrect, as software should be written in software, not hardware. All of the other items are correct.
02:25:00 This video discusses the different types of software that computers need to function, and the importance of having both the hardware and software. The B letter is wrong, because a person must have both a body and soul to provide life to a computer, and the computer must have both hardware and software. Hardware includes the physical parts of the computer, such as the CPU and memory, while software includes the programs that interact with the user and run on the computer. A system administrator, or the "god" of a computer, is the software that manages other software and oversees the computer's overall operation. When studying for a computer test, it's important to remember the different types of software and the system that each operates on, such as Windows or Linux. In addition, the speaker discusses the importance of having an editor for text, a spreadsheet, an electronic presentation editor, and a software to create graphics for websites.
02:30:00 In this video, Professor Renato da Costa discusses how the three main types of software in use on computers--basic software, utility software, and application software-- are classified and explained. He also covers how a computer has to have basic software in order to function, and how to test if a software application is an "utility" or "applicative" software. Finally, he discusses how a person's diet can affect their health and how medication can be classified as either a "basic software" or an "applicative software."
02:35:00 This YouTube video introduces the different types of computer software and how they are useful. The professor discusses the importance of computer software, explaining that while applications are what are good for people, the operating system is what is good for the machine. He goes on to discuss various computer programs and their respective uses, such as word processing, spreadsheet software, photo editing applications, and car control software. He also explains that some systems, such as cars and aircraft, have computer systems on board that allow for more efficient and safer operation. The professor concludes the video by emphasizing the importance of computer software and how it can be used in a variety of ways.
02:40:00 This video discusses the different types of computer systems that have been developed over the past 50 years, and how some of them, such as operating systems, have never been well-known. It then discusses the importance of software-embedded systems, which are systems that are executed only on computers that are of the server type, but is incorrect to say that server-based systems use Linux. System-embedded systems are executed on large-frame computers that accept installed software by users, and they do not accept user-installed software. Systems-embedded systems are installed on large-frame computers that are known as servers, and they accept software that is installed by the manufacturer. I personally prefer the example of a central multimedia system, which I find more interesting because it changes even though this topic has been around for a long time. Today, we are used to using TVs and installing apps on TVs, and there has arisen a new company called Disney Plus. It is possible that your TV allows installation of legal beauty applications. However, if people think about TVs from 10 years ago, they had menus that allowed you to increase the volume, change channels, and have them pre-installed. They also had a system that was factory-installed and could not be changed,
02:45:00 In this video, Professor Renato da Costa discusses different topics related to computer technology, including an overview of the different types of software available on a computer, a discussion of computer operating systems, and the dangers of viruses. He also covers the basics of database management systems. Finally, he concludes the video by discussing the importance of software maintenance and reminds viewers that software can be classified in either ascending or descending order.
02:50:00 This video discusses the different topics related to technology, including the dangers of viruses. The presenter explains that a virus is a program that can cause harm to a computer, and that it is logical for a virus to exist. The presenter also discusses the role of software licenses in software freedom, and the difference between free and proprietary software. The presenter also provides a brief overview of free and open-source software applications.
02:55:00 This video discusses the different types of firmware that are used in practice. It covers the setup process and the need for a firmware that is "firmware-firm." The various examples given demonstrate how a firmware can be essential in the operation of various devices. One example is the use of a micro-oven with built-in firmware that allows it to heat up to the maximum power setting for four minutes. Another example is the smartphone that was previously un-able to be unlocked, but was successfully unlocked after the manufacturer's authorized service was visited in Rio de Janeiro. The main problem with this particular video is that the concepts of firmware and system-level Embarcado are often confused. The main take-away is that when setting up a device, it is important to understand which firmware is being used and whether or not it is the system-level Embarcado.

03:00:00 - 03:35:00

In this video, Professor Renato da Costa discusses the importance of computer science and its impact on society. He also covers the different fields of computer science, including software, hardware, and data processing.

03:00:00 The video discusses topics related to computer technology, specifically software for maintaining and repairing computers, firmware (software that precedes the operating system on electronic equipment), and software for data processing, such as word processors and spreadsheet programs. The main goal of these programs is to manage the computer's function, without getting too technical. One example of a software program that manages computer function is the BIOS (basic input/output system), which is a set of instructions that are pre-programmed on a computer's ROM (read-only memory). Setup (the program that starts up the computer) and post (the program that updates the operating system and helps keep it running) are also pre-programmed on ROM. Finally, we discuss the testing of computer knowledge. In this video, we focus on the computer's basic programming, which is what the BIOS is for.
03:05:00 In this video, Professor Renato da Costa discusses the different types of software, from basic utilities to specific application programs. He explains that a system's operating system is a basic software application, and can be either a basic utilities software or an application program. He goes on to say that Linux can also be considered a basic software application, as it precedes Windows in the operating system hierarchy. He then highlights the different types of software, with applications like PowerPoint and Word being considered basic utilities, while Android and WinRAR are considered application programs. Finally, he introduces the term "utilitário" and describes its specific usage for software in the operating system hierarchy.
03:10:00 This video discusses different topics related to computer technology, such as software and hardware. It covers the basics of a software, such as a básico utilitário and aplicativo, and gives an example of a Windows program and a Linux program. It also discusses the different types of software, such as aplicativos and software básicos. The video concludes by discussing the basics of backup and software.
03:15:00 Renato da Costa discusses the use of software utilities in the classroom, discussing how some, like editors for text and graphics, are helpful while others, like antivirus software, are not. He goes on to say that although Wikipedia is a collaborative website, its content is not verified and cannot be used to corroborate an academic paper. Finally, he warns students not to rely on Wikipedia when writing academic papers.
03:20:00 The video discusses the different topics related to technology, specifically Prof. Renato da Costa's thoughts on the topic of research methodology. Prof. Costa points out that while Wikipedia can be a useful resource, you will likely want to consult a source from the Wikipedia article itself in order to cite it as a reference in your thesis or dissertation. He goes on to explain that you can find information on Wikipedia in books, but these will usually be out of date by the time you need it for research. He also mentions that there are authors who will write articles in books several decades after they were originally written, and that other authors might consider everything in an article to be a part of the same book. Finally, he provides a quiz on Gabarito, with the correct answer being "D".
03:25:00 This video teaches basic concepts of hardware and software, including the difference between drive and driver. It also discusses computer components and explains that hardware is made up of drive and driver, while software is a program to install equipment. In the end, the instructor discusses a quiz question that is commonly repeated in competitions. They have to cut it out because it is too long. They say goodbye and wish everyone good luck. The video discusses the difference between hardware and software, and explains that hardware is made up of drive and driver. It also explains that software is a program to install equipment. The quiz question asks the students to identify the correct answer about the concept of hardware and software. The only answer that is correct is that drive is hardware and software is a program to install equipment.
03:30:00 This video is a introduction to Professor Renato da Costa's topicspecial lectures on information technology. In this video, Renato discusses the benefits of anxiety control, and how to approach and perform a successful test. He also discusses the importance of using effective tools in one's work, and how regular exercise can improve mental focus. Finally, he gives advice on how to manage one's work and personal life simultaneously.
