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?
210 mm / 25.4 = 8.27 in
297 mm/25.4≈11.69 in
Step 2: Multiply by the desired dpi (200 dpi)
Width in pixels: 8.27×200≈1654 px
Height in pixels: 11.69×200≈2338 px
42.- Which resolution would the same picture need to have a 300 dpi picture?
Width: 8.27 in
Height: 11.69 in
Width in pixels: 8.27×300≈2481 px
Height in pixels: 11.69×300≈3507 px
Required resolution at 300 dpi: 2481 × 3507 pixels

Use unique passwords for each account:
Never reuse the same password. This limits the damage if one account is hacked.
Create strong, complex passwords:
Combine uppercase and lowercase letters, numbers, and symbols. Example: G!raffe_2025#
Use a password manager:
Password managers (like Bitwarden, 1Password, or LastPass) can create and remember strong passwords for you.
Enable two-factor authentication (2FA):
Add an extra layer of protection so that even if someone gets your password, they can’t access your account without the second verification step.
Change passwords regularly and avoid sharing them:Update passwords every few months, and never send them by message or email.
