Relationship of Human Consciousness with the Computer

Computers and their relationship with the computer, I believe that computers have become necessary in our daily lives; such as at work, school, university, etc.

I think that although it is necessary in our life, it is not vital for us, and we still have a conscience when it comes to the computer.

The Most Dangerous Virus in the Internet

In more technical terms, a computer virus is a type of malicious program or code written to modify the operation of a computer. Furthermore, it is designed to spread from one computer to another. Viruses insert themselves or attach themselves to a legitimate program or document that supports macros in order to execute its code. 

A virus can cause various problems on an infected device. This can quickly consume all of your computer's available memory, causing your system to slow down or crash. Viruses can damage data, destroy files, format hard drives, or make drives unreadable.

The Most Dangerous

1. Barrotes

It emerged in 1993 and was the first known virus in Spanish. It is activated every January 5th and it is easy to identify, because it makes vertical bars of colors appear on the computer screen.


2. Falling Letters

Also known as Cascade, it appeared in Germany in 1997. Like the Barrotes, it is easy to recognize because it generates effects on the screen. It causes the letters to descend like water from a waterfall on the infected devices.

3. Friday the 13th

Created in 1998, its name has to do with its attack system, because it is only activated when the calendar shows the date Friday the 13th. On that day, this malware eliminates all the programs and files executed on the system. Also called Jerusalem, this virus was spread through emails or CDs.

4. Melissa

It appeared in March 1999, and like ILoveYou or Anna Kournikova, it spread massively through email services. It emerged in the United States and the message it used was “Here is the document you requested… don't show it to anyone else”.

5.ILoveYou

Launched in 2000, it was sent via email with the subject line “I LOVE YOU” and a malicious attachment. It is considered one of the most dangerous because it infected 10 million computers and is still running.

6. Anna Kournikova

Launched in 2001, this virus was sent through an email containing an image of the famous tennis player. When the user opened the file, the mail was automatically forwarded to all his contacts in the Outlook electronic messaging system.

7.Nimda

This computer worm was created in China in 2001, and was considered very dangerous due to its propagation method, which combined three different systems. Its name is short for administrator, but spelled backwards, because it allowed the driver to acquire administrator privileges.

8. Blaster

Also known as Lovsan, Blaster is a worm created in the United States in 2003, designed to attack computers with a Windows operating system. In its code it contained two messages, one of which read: “Billy Gates, why are you making this possible? Stop making money and fix your software."

9. SQL Slammer

It was created in 2003 and attacked more than 500,000 servers in just a few days. This computer worm is considered one of the most dangerous due to the surprising speed of its propagation.

10. Zeus

Launched in 2007, it became famous because it was used to steal passwords and bank details, that is, sensitive information for the user. It was detected only on computers with Windows system. It was a Trojan virus that allowed the driver to take over some functions of the infected PC.

The History of Windows

In 1975 Bill Gates and Paul Allen founded the Microsoft company in the United States, with the aim of developing and marketing programs to run the Altair 8800, a microcomputer designed in 1974. Gates and Allen developed the first programming language for Altair Basic.

In 1979 Microsoft released the first operating system called Xenix to the public, which is now obsolete. In 1981 he created a new operating system that allowed him to achieve success, the DOS (from the acronym in English Disk Operating System that means disk operating system).

In 1985 the first version of the currently known Windows operating system was released. Some time later, in 1989, another product appeared that is also still valid today and that works together with the Windows interface: the Microsoft Office software package, which consists of a set of integrated applications, such as Microsoft Word or Microsoft Excel. .

In 1990 Microsoft released Windows 3.0, a new version of the operating system. As he developed improved versions, he changed the corresponding number in the name. However, in 1995 it released Windows 95 which offered a completely new interface with an improved file explorer, quick access start menu and better hardware compatibility among other benefits.

As of 2012, the Windows 8 operating system was launched with a new image design that was more interactive and that allowed it to be executed through touch screens. It was a version of the software designed to be run from other devices, such as mobile phones or tablets, and to coexist with the rise of the Internet and social networks.

Throughout the evolution of Microsoft, the Windows operating system has been presenting different improved versions. Among the main ones stand out.



Windows 1.X/2.x. 

It meant a big change for the operating systems of the time that were based on text representations. This version used monochrome type graphical representations.

Windows 3.x. 

It was launched as a multitasking and purely color interface that contained new computing concepts, such as icons, folders, taskbar and wallpaper, among others.

Windows NT (New Technologies). 

It was released as a different version designed for connectivity to servers on a network. It competed with the UNIX operating system.

Windows 95. 

It was a completely improved version with 32-bit environment management and the plug and play function that allowed a device to be connected and run on the computer without prior configuration.

Windows 98/98 SE. 

It was a very similar version to its predecessor, but it offered an improvement for the recognition of a greater variety of external devices through the plug and play function.

Windows 2000. 

It was an evolution of the Windows version with improved hardware recognition, 64-bit support and the Active Directory service (Active Directory), which allowed sharing devices on the network, such as a printer, a router or a computer. server with other computers that were also connected to the network.

Windows Millennium. 

It was a version similar to its predecessor, but with the important improvement of a wide recognition of external devices, through the renewed plug and play function through the USB port inputs.

Windows Xp. 

It was an outstanding version due to the possibility of executing remote assistance, that is, it allowed the user to share control of his computer with another computer that was connected to an internal or external network.

Windows 7. 

It was launched as a greatly improved version in terms of compatibility, both for programs and external connectors, even for working with multiple monitors simultaneously. It also offered higher data processing speeds that allowed a quick graphics transition.

Windows 10. 

It consisted of a new generation of the operating system with an interactive whiteboard format typical of cell phones. In addition, its renewed interface offered better features for working connected to clouds or external servers.

The most used operating systems



The invention of the first operating system is by Gary Kindall, (1942-1994), however, it is attributed to Bill Gates. Kindall was a doctor of computer science and created the first operating system for personal computers, the CP/M.

All operating systems use a graphical user interface, that is, what allows you to use the mouse to click on icons and buttons, or interact with any other element to execute actions or tasks. This is how we tell the computer what to do.



The most important operating systems in the world:

  • Windows.
  • Linux.
  • iOS.
  • Chrome OS.


The operating system has three essential components or software packages that allow interaction with the hardware:


Microsoft Windows

It was developed in the 1980s. Its most recent versions are Windows 11, Windows 10; Windows 8, created in the year 2012; Windows 7, in 2009; and Windows Vista, created in 2007.Windows viene instalado, por defecto, en la mayorĂ­a de los computadores nuevos.

Mac OS X

It is the operating system created by Apple Inc. and is installed on all its computers. The most recent versions are: Monterrey, BigSur and Catalina; and some, a little older, are: Mojave, HighSierra, Sierra.

Linux Ubuntu

It is an open source operating system. This means that it can be modified and distributed by anyone around the world. This is one of its advantages, since you do not have to pay for it and you can choose between the different versions that exist.

Chrome OS.

They run Chrome OS, which has cloud storage, the best elements of Google built in, and multiple levels of security.

FreeBSD.

Open source operating system for computers based on the x86, Intel 80386, Intel 80486, and Pentium architecture CPUs. It currently runs on eleven different architectures including Alpha, AMD64, IA-64, MIPS, PowerPC, and UltraSPARC.

OpenBSD.

Complete, free, cross-platform Unix-like operating system based on BSD. According to its website, it seeks to emphasize: "portability, standardization, correctness, proactive security, and integrated cryptography."

Android-x86 (GNU/Linux)

Was an unofficial initiative for Google's Android mobile operating system to run on devices with x86 processors from AMD and Intel, instead of ARM RISC chips

Solaris

Unix-like operating system developed since 1992 initially by Sun Microsystems and currently owned by Oracle Corporation after its acquisition of Sun. Successor of SunOS, it is a system officially certified as a version of UNIX.
