Digital Security

Always use the same password for all my accounts and applications. I do not like to use complicated passwords because it is difficult to remember and too long. 
What do you think?.


Absolutely, here is the English translation of the previous response:

Yes, it poses a very serious security problem to use the same password and email address for everything.

This is due to a risk called "password reuse" or the "credential stuffing" attack.

Why is it dangerous?

  1. Domino Effect: If a single platform you use suffers a security breach and your password is leaked (which happens frequently), cybercriminals can use that email and password combination to automatically try to access all your other accounts (social media, online banking, main email, streaming services, online stores, etc.).

  2. Access to Your Main Account: If the password is the same one you use for your main email, the risk is exponential. Email is often the "master key" that allows you to reset passwords for almost any other service. If they gain access to your email, they could potentially take control of your entire digital life.

  3. Identity Theft and Financial Loss: By gaining access to multiple accounts, attackers can steal sensitive information, make fraudulent purchases, and in severe cases, commit identity theft.

Security Recommendations:

Of course! Here are the 5 essential cybersecurity tips translated into English:

  1. Use Unique and Strong Passwords: Never repeat the same password across different accounts. Use a password manager to create and remember complex, distinct keys for every service.

  2. Enable Two-Factor Authentication (2FA/MFA): Turn this on for all your critical accounts (main email, social media, etc.). This adds a crucial layer of security, requiring an extra code (usually from an app) to log in, even if your password is leaked.

  3. Keep Everything Updated: Make sure your phone/computer's operating system and all your applications are always running the latest version. Updates fix security flaws that hackers could exploit.

  4. Beware of Phishing: Be suspicious of emails, messages, or suspicious links, especially if they ask for personal information or passwords. Always verify the source before clicking.

  5. Avoid Public Wi-Fi Networks: Do not enter passwords or banking details when connected to open Wi-Fi networks in public places. These networks are often easy for third parties to intercept.

Input Devices

 keyboard:

The keyboard is the peripheral hardware that allows the input of data, both on a computer and on other technological devices, such as smartphones, tablets, ATMs, and others.

It is a peripheral device made up of keys or buttons arranged in a special order. With them, it is possible to give commands to the software of the device being used. In this way, it enables the user's interaction with the functions of the software.

The Keyboard and Its Functions

Computer keyboards have the same layout and order of alphabetical and numerical keys as typewriters. It is due to this arrangement that it is named the "QWERTY keyboard."

Modern keyboards include additional keys or buttons for other functions, such as multimedia control, shutdown, internet access, and startup programs.The keyboard is used to:

Interact with device software

Give instructions to devices

Enter data and information

Control multimedia functions

Enter and edit text

Perform mathematical operations

Play video games


Mouse:

What is a mouse?

Designed to facilitate user interaction with the graphical interfaces of numerous computer systems. Today, it is a popular and traditional computing accessory.

Mouse functions

The mouse's purpose is to reflect the movements of our hand in the virtual graphic environment of the system, that is, to serve as an extension or representation of our will within the computer system . Thus, we can dictate to the system which applications we want to run, by pressing the button (or one of them: the Macintosh mouse has a single button, while the IBM mouse has two ) on the icon that represents it, or even where we would like to move it in the folder system, represented by windows that display its contents. The mouse can also serve as an interface with application software such as video games, spreadsheets, and more.

Storage Devices (hard drives)

 What is a Hard Drive?

A hard drive is a storage unit where we can keep our files stored. Being a non-volatile storage unit means that it can store the data inside even when it is not connected to power. 'Hard drive' has become a generic term, since originally storage devices with hard disks were called hard drives and removable ones were called floppy disks, although nowadays the term 'hard drive' also refers to other storage units such as SSDs and some external drives.

We can say that a hard drive is the secondary storage unit in a PC, unlike what many users might think, which is that it is the primary one; the primary unit is the RAM.


What is a Hard Drive for?

What is a Hard Drive for? Basically, the purpose of a hard drive is to store information. A hard drive is used to save our data even if we disconnect it from the power supply, so it is designed to last over time, whether for a long or short period. Additionally, a hard drive serves as a secondary storage unit where the operating system and our computer files can be stored.

With a hard drive, you can also make backups. Since it is a device that stores data, you can copy photos, videos, documents, and other types of files you want to keep for security, memory, or any other reason, and later retrieve them when they are useful to you. You can connect it using an external interface (such as USB with its corresponding enclosure or adapter), or you can also use it internally in addition to the secondary hard drive you use as your main drive on your computer.

Power Supply

 What is a Power Supply?

A power supply is an essential component of any electronic device since it is responsible for giving it life. It is in charge of doing what a power supply does, which is managing the energy input from the grid and adapting it to power the equipment. Therefore, a power supply is a device responsible for providing the right and necessary current to an electronic device.


What is a Power Supply For?

A power supply is used to provide energy to an electronic device. Continuing with the topic of desktop computers, the power supply provides energy to the motherboard, CPU, graphics cards, HDDs, SSDs, fans, CD drives... In short, it powers everything that needs energy, using different types of cables to do so.

Power supplies provide energy to SSDs and HDDs through SATA power connectors, and to fans through 3- or 4-pin Molex connectors or via the motherboard itself (which is powered by the 24-pin ATX connector). In this way, all components receive power from the power supply. Additionally, power supplies protect all components through a wide range of dedicated systems.

Graphics Card

 What is a graphics card?

A graphics card is an electronic component responsible for processing the information received by the device and then displaying it visually to the user through a monitor.

What is a graphics card for?

A graphics card serves as an output for the user, allowing them to see the interaction with the computer in real time. A computer can turn on without any graphics card (dedicated or integrated) but it will not display anything on the screen, and therefore, we will not know what we are doing.

The graphics card is one of the components with the most potential for overclocking, thereby increasing its performance (as well as power consumption and temperature) to get even more out of these circuits. Similarly, they can be used for underclocking, which is the opposite technique, lowering temperatures, consumption, and performance.
