Cloud computing, also known as cloud services, cloud computing, computing cloud or simply "the cloud", is a paradigm that allows computing services to be offered over a network, which is usually the internet.
La computación en la nube (o cloud computing, en inglés) es una tecnología que permite acceder remotamente, de cualquier lugar del mundo y en cualquier momento, a softwares, almacenamiento de archivos y procesamiento de datos a través de Internet, sin la necesidad de conectarse a un ordenador personal o servidor local.
In simple terms, the cloud allows you to store and access data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. ... Storing data on a home or office network is different from using the cloud.
Open Source Software or OSS is the software whose source code and other rights are normally exclusive to those who own the copyright.
Open Source are published under an open source license or are part of the public domain.
In licenses compatible with the Open Source Definition, the copyright owner allows users to use, change and redistribute the software, to anyone, for any purpose, either in its modified form or in its original form.
Often open source software is developed collaboratively and the results are published on the internet. The software is the best example of open source development and is compared to so-called "user-generated content".
Of course, we cannot forget that the open source system lowers the barriers to innovation, so that any user can share their idea in the market.
In the same way, by using these programs, you no longer depend on the work of a company dedicated exclusively to software maintenance, being able to open doors to anyone who has the knowledge and skills necessary to do so remotely.
Deybith Venegas Aleman web page which is a web page? A web page, electronic page, digital page or cyberpage, is a document or electronic information capable of containing text, sound, video, programs, links, images, hyperlinks and many other things, adapted for the so-called World Wide Web (WWW), and that can be accessed through a web browser. Web pages can be stored on a computer or on a remote web server. The Web server can restrict access only to private networks, for example, on a corporate intranet, or it can publish the pages to the World Wide Web. Access to web pages is done by means of a transfer from servers, using the Hypertext Transfer Protocol (HTTP).
that allow us to make the web pages? they allow us to create a document that is visible using an internet browser. This document can contain texts, images, videos, sounds, files and other elements that together make up the structure of a web page. A web page is mainly composed of information on a feasible topic (text only or multimedia modules) as well as hyperlinks; It can also contain or associate style sheet, style data to specify how it should be displayed, and also embedded applications to allow you to interact with more people.
what is the importanceof the web pages? A web page serves as a prop to exist on the Internet. It's that clear. The website should be the center of any online strategy. It serves to make yourself known among all those who do not know your brand, company or SME, or the products or services you offer. A website is the center of the SEO positioning strategy. The importance of a web page is born in the way of understanding that the internet is a place for everyone, it is currently one of the most used means of communication by the masses, and it is relevant to understand that we will find everything we want through this medium.

what function has a web page? A web page, can have several uses, can be used as a means of communication for various topics, such as news, culture, medicine, science, technology, comments on various topics, forums, education, debate, games, music, movies, etc. but the function of any website is exclusively to disseminate information of all kinds: commercial, institutional, educational, journalistic, governmental, etc. From the programming point of view there are pages with static content and dynamic content.
Virtual Machine What is a Virtual Machine? A virtual machine is a software that we install on the computer that allows you to run several operating on the same hardware.
For example: On the same operator i can be using multiple operating systems. MacOs, Linux, Windows
Characteristics: The great majority of virtual machines, as for example Virtualbox or VMWare allow you to install any operating system such as Linux, Andrid, Chrome OS,etc. However, there are other virtual machines, such as Virtual PC, Hyper-V or Parrallels, which are mainly intended to virtualize Windows. Each of the operating systems that we virtualize is completely independent from the other operating systems. In the case that one of the virtual machines stop work, the rest will continue to work without any problem. The operating system virtualized is used as if is had been installed on the computer.
A virtual machine has all the elements that has a real computer, but a difference of a real computer that’s elements are virtual instead of being physical. All the elements of a virtual machine are encapsulated in a set of files.
Some of the important points for optimal performance of the virtualized operating system are: Have a fast processor and hardware virtualization capacity. Have enough space on your hard drive. Have sufficient and adequate RAM memory.
UTILITIES PROVIDED BY VIRTUAL MACHINES: To test operating systems. To use software that is not on the operating system. For example: We are Linux users, and we want to use Photoshop, we can do it through a virtual machine.
Advantage: Using virtual machines means having less physical equipment and money
They provide the same functionality as physical computers.
They run applications and various operating systems. Disadvantages:
To use a virtual machine properly we need a powerful computer.

A lot of information (and misinformation) circulates online about the term "virus", so let's make it clear and define this concept once and for all: a computer virus is a malicious and self-replicating program or code that sneaks into your device without your knowledge or permission .
Some viruses are just plain annoying, but most are destructive and designed to infect and take control of your device. A virus can spread through computers or networks by making copies of itself, in the same way that a biological virus is transmitted from one person to another.
How do computer viruses work?
"Computer virus" is a general term that includes many different types of viruses, delivery mechanisms and impacts. In terms of their exact operation, computer viruses can be divided into two categories: those that begin to infect and replicate as soon as they arrive on the computer and those that remain inactive, waiting for you to activate them (that is, waiting for you to activate them). run the code inadvertently).
Viruses have four phases (inspired by biologists' life cycle classification of real viruses). • Sleeping phase : This is when the virus remains hidden in your system, waiting. • Propagation phase : It is the moment when the virus goes viral: it replicates and stores copies of itself in files, programs and other parts of the disk. Clones can be slightly altered in an attempt to avoid detection, and they also self-replicate, creating more clones that keep copying, and so on. • Activation phase : A specific action is usually required to trigger or activate the virus. It can be a user action, such as clicking an icon or opening an application. Other viruses are programmed to come to life after a certain time, for example, after the computer has been restarted ten times (in order to hide the origin of the virus). • Execution phase : The “fun” begins. The virus releases its payload , the malicious code that damages the device.
Computer viruses can spread over the Internet through various infection mechanisms. Viruses can reach your computer in the following ways:
Email messages: Email, the favorite method of cybercriminals , can carry harmful attachments (in the form of executable files such as .EXE or .ZIP ) and malicious links, or even contain an infection directly in the body of the message, in the form of HTML.
Downloads : Hackers can hide viruses in applications, in documents sent via file-sharing services, in plug-ins, and almost anywhere you can think of where there are files to download.
Messaging services : Viruses can spread via SMS or messaging services such as Facebook Messenger, WhatsApp, and Instagram. In these cases, as in email, they can take the form of malicious links, attachments, and executable files.
Old software: If you haven't updated your applications or operating system in a long time, you are almost certainly experiencing vulnerabilities that cybercriminals can exploit to sneak viruses into you.
Malvertising: There may be hidden viruses in online advertisements such as advertising banners. Malvertising is very insidious because criminals can hide their malicious code even on legitimate and trusted websites, such as The New York Times or the BBC , that have suffered such attacks. Fortunately, there are simple ways to protect yourself from these attack vectors and we will discuss these shortly.
What do computer viruses do
After entering the execution phase and releasing its payload, a computer virus starts the attack, so it will begin to suffer negative effects on your device. As viruses hijack system code and resources to replicate, you may also experience problems during this phase. Be on the lookout for the following effects: • Slow permance • Damaged or missing files • Incessant pop-ups • Constant hard drive activity • Crashes or crashes of programs and the operating system • Strange things happen, like apps that open themselves or new files that appear randomly
Aside from causing these performance problems, viruses can also steal confidential information such as usernames, passwords, or credit card numbers. Some viruses can send messages to all your contacts to try to trick them into getting infected as well, which is another method of spread.
Signs that your device could be infected Have you ever been tipped off by friends of a suspicious email from one of your accounts? It is a classic sign of infection with a computer virus. One of the ways that viruses continue to spread is by spreading themselves to your entire contact list (whether by email, text message, or other messaging service). The aim is to try to trick recipients into downloading the virus. As mentioned before, there are other symptoms of computer virus infection, such as an abundance of pop-ups, device and application crashes and crashes, unexpected slow performance , and most of all, unexplained changes to the device or account settings.

Messaging services : Viruses can spread via SMS or messaging services such as Facebook Messenger, WhatsApp, and Instagram. In these cases, as in email, they can take the form of malicious links, attachments, and executable files.
Old software: If you haven't updated your applications or operating system in a long time, you are almost certainly experiencing vulnerabilities that cybercriminals can exploit to sneak viruses into you.
Malvertising: There may be hidden viruses in online advertisements such as advertising banners. Malvertising is very insidious because criminals can hide their malicious code even on legitimate and trusted websites, such as The New York Times or the BBC , that have suffered such attacks.
Fortunately, there are simple ways to protect yourself from these attack vectors and we will discuss these shortly.
What do computer viruses do
After entering the execution phase and releasing its payload, a computer virus starts the attack, so it will begin to suffer negative effects on your device. As viruses hijack system code and resources to replicate, you may also experience problems during this phase. Be on the lookout for the following effects:
• Slow permance
• Damaged or missing files
• Incessant pop-ups
• Constant hard drive activity
• Crashes or crashes of programs and the operating system
• Strange things happen, like apps that open themselves or new files that appear randomly
Aside from causing these performance problems, viruses can also steal confidential information such as usernames, passwords, or credit card numbers. Some viruses can send messages to all your contacts to try to trick them into getting infected as well, which is another method of spread.
Types of computer viruses
• Direct-action viruses:
• Boot sector viruses :
• Resident viruses :
• Multipartite viruses
• Polymorphic Viruses
• Macro viruses:
Signs that your device could be infected
Have you ever been tipped off by friends of a suspicious email from one of your accounts? It is a classic sign of infection with a computer virus. One of the ways that viruses continue to spread is by spreading themselves to your entire contact list (whether by email, text message, or other messaging service). The aim is to try to trick recipients into downloading the virus.
As mentioned before, there are other symptoms of computer virus infection, such as an abundance of pop-ups, device and application crashes and crashes, unexpected slow performance , and most of all, unexplained changes to the device or account settings.
