 ♣ 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 x 1 inch ➗ 254 mm = 0,82 inches

297 mm x 1 inch ➗ 254 mm = 1,16 inches

0,82 x 200 = 164 inches

1,16 x 200 = 232 inches

• Resolution: 164x232 inches

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

210 mm x 1 inch ➗ 254 mm = 0,82 inches

297 mm x 1 inch ➗ 254 mm = 1,16 inches

0,82 x 300 = 246 inches

1,16 x 300 = 348 inches

Situation 1

"I use always 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?.... "

MAKE A WEAK PASSWORD 

This happen when you don't are concious of that a person can know all your private information knowing your password. 

You have to do different and complicated passwords for all your accounts and applications, trying long passwords with numbers and symbols.

If you make a weak password a person can steal all of your information and information of your family or friends too.

A weak password is short, common, a system default, or something that could be rapidly guessed by executing a brute force attack using a subset of all possible passwords, such as words in the dictionary, proper names, words based on the user name or common variations on these themes, and a strong password is: At least 12 characters long but 14 or more is better. A combination of uppercase letters, lowercase letters, numbers, and symbols.

What do you need to make a computer?

 Building a computer may seem complicated, so here are some of the main components to make a computer and it works:

- Motherboard

- CPU

- RAM

- GPU

- SSD

- PSU

- Case

- OS

8. Operating System

When you build a PC, you don't automatically have Windows included. You'll have to buy a license from Microsoft or another vendor and make a USB key to install it.

Of course, you will need to install the OS onto your Computer, and there are several ways to do this. You can use a Win OS Install DVD if you have one and your PC has a DVD Drive.

Nowadays, though, as optical drives are becoming a thing of the past, the Operating System is usually either downloaded directly from the Internet (for you to create your own boot medium on DVD or thumb drive), or you can buy it on a USB Stick (Thumb-Drive).

The most expensive OS can cost $199,000

7. Case

The Computer case is nothing more than a fancy-looking box that holds all of the PC’s components. It can be opened and closed and has pre-defined areas with screws and holes where all of the components are supposed to be placed and attached to.

PC Cases come in different colors, and sizes, with or without fans; some have RGB lights, some don’t and some have glass side panels

Example of a computer case:

You should pay around $100 and $150

6. PSU

PC won’t work without a power supply to supply the PC with power.

Your power supply unit is a little box that keeps the electricity running to every component. It determines how quick and powerful your PC can be. The faster it is, the more power it needs, and you always want to have a little more than you need, just in case. Just like GPUs, PSUs are also in and out of stock right now.
