EDITED PICTURE

For this project, I used the GIMP 2.10.12 application. As you can see, in the first image there are no horses and the sky is different. Using the tools and instructions from the teacher, I was able to edit the image, adding horses and a new background.

 MADRID

This photograph was taken in Madrid and later edited using GIMP 2.10.12 to refine the original perspective.

A streetlamp was removed to minimize visual distraction.

The aim was to keep the focus on the main subject of the image.

The final composition is cleaner and more visually balanced.

PROJECT OF FLAGS

SWEDISH FLAG

EUROPEAN UNION FLAG

USA FLAG

I have used the application Inkscape because it is a vector design program that allows you to create precise shapes and use exact colors, which is very useful for designing flags.

The Swedish and European flags were chosen by the teacher because their designs are simple and help to learn how to place shapes and colors correctly. I chose the United States flag because it is more interesting and a bit more complex, with stripes and stars, which helped me practice repeating elements and organizing the design better.

Inkscape has helped me work in an organized way and achieve a clean final result.

DIGITAL IMAGE - PROBLEMS ( Theme 1)

PROBLEMS

 41.- Think you want to print out a photograph with a size of DIN A4: 210 × 297 mm maintaining a printing quality of 200 dpi. Which resolution would the image need?

DIN A4 size: 210 × 297 mm = 8.27 × 11.69 inches.
At a quality of 200 dpi:

Width = 8.27 × 200 = 1654 pixels
Height = 11.69 × 200 = 2338 pixels

Therefore, the image should have a resolution of 1654 × 2338 pixels (approximately 3.87 MP) to be printed in A4 size at 200 dpi quality.

42.- Which resolution would the same picture need to have a 300 dpi picture?

DIN A4 size: 210 × 297 mm = 8.27 × 11.69 inches.
At a quality of 300 dpi:

Width = 8.27 × 300 = 2481 pixels
Height = 11.69 × 300 = 3507 pixels

Therefore, the image should have a resolution of 2481 × 3507 pixels (approximately 8.7 MP) to be printed in A4 size at 300 dpi quality.

ARTICLE 2: The Problem of Using the Same Password for All Accounts

Why Using the Same Password Everywhere Is a Big Security Risk?

Problem Description

Many people often use the same password for all their accounts and applications. They avoid creating complicated passwords because they are hard to remember and too long. While this might seem convenient, it significantly increases the risk of cyberattacks. If one of your accounts is compromised, hackers can use the stolen password to access all your other accounts, leading to identity theft, financial loss, and personal data breaches.

What is Password Reuse?

Password reuse is the practice of using the same password across multiple online services or accounts. This behavior is a major security risk because it makes it easier for attackers to gain unauthorized access to many of your accounts if one password is exposed.

5 Tips to Avoid the Password Reuse Problem

1. Use a Password Manager: A password manager securely stores unique passwords for every account, so you don’t have to remember them all.

2. Enable Two-Factor Authentication (2FA): Even if a password is compromised, 2FA adds a second verification step to protect your account.

3. Create Memorable Passphrases: Instead of complicated passwords, use longer but easy-to-remember phrases (e.g., "CoffeeSunshine2025!").

4. Change Passwords Regularly: Update important passwords periodically to minimize the damage if they are stolen.

5. Avoid Using Personal Info: Don’t use birthdays, names, or common words in your passwords—they are easy to guess.
