excel fourth work

 we did a similar project as the last one we made, but this time measuring the kinetic friction.

We measured the generalaceleration and look up the times to put the numbers  in the chart.

This is the following chart:

Excel third work

 In this work we measure the aceleration with g, throwing our movile from differenta angles and then measuring them in a table on excel. This is the table that we end up with. In this table we put the 16 experiments and measure  several things such as measure the radians and the eror, also the porcentaje of each error. 

The table:

excel second work

 In this work we used an app in our movile phones to measure different angles, the we writhe the results in an excel and make a table with all the things that we calculate.

excel first work

 we made a graphic measuring calculating different numbers.

the final graph it has to be a kind of spiral.

         

the graph:

Final work

 In this work we went outside and take photos of ourselves making funny poses, then we take a template  of the internet, mine is a cinema themed template. Then we take the photos one by one, crope  it and the give it an interesting colour for more fun.

Working with layers

 In this work we use layers to make different images using geometric forms and then with the crop tool we made each image on a scale of 1:1 and the last one on a scale of 16:9.

image 4 (16:9 format):

The other excercise was in a image put some animals in a lake and the change the backround. I used the crop tool, the ereaser and the layers to change those things.

Photo only with animals:

Photo with animals and another backround:

Jimp editing photo

In this project we change the perspective of a photo, improve the cuality and erase some elemets of the image, in my case I ereased the statue and a part of a tower of the church. 

First I changed the perspective with the crop tool and croped the edges, Then I ereased the tower and then decided to erease the towerb of the church to make more changes.

Finally I write my name and exported as a jpg image to put it on the blog

Problem 1

 I think my telephone has a type of malicious software that makes me believe that my cell has a virus. Sometimes, it will fool me into believing that my security measures are old. In turn, they offer new updates for my security settings. So I do not know what to do… 

firts you have to know that:

Fake virus warnings are the common tactic used by scammers to trick you, and if you're not cautious, they might get real malware to your device.

If you have received a warning from Google stating that your phone is infected with viruses, it is important to take immediate action to protect your device and your personal information.

The most common types of mobile viruses targeting Androids are adware, ransomware, spyware, trojan horses, and worms. The term “virus” is now widely used to describe almost any kind of security risk, but it is a specific form of malware. 

These harmful programs are designed to gain access to your Android phone, retrieve personal information, increase your data usage and damage the device. Some are even designed to trick you into providing all of that information yourself.

 5. Install anti-malware software: Installing an antivirus app is an effective way to automatically clean your phone of viruses and malware. Consider installing a reputable antivirus app, such as AVG AntiVirus for Android, to keep your device protected in real-time.

 

 

Problem 2

 My mobile phone is asking me to install my operating system update but I do not feel like to do so… Do you think it is really important to update it, why?    

First you have to know that:  

Operating system updates provide fixes to possible bugs and security holes, along with cleaning up outdated software that may slow down your device. Ensure that your computer, mobile phone, or tablet is using the latest version of its OS to protect your devices and data from cybersecurity issues.

By installing the latest updates, you can reduce the risk of cyberattacks and protect your personal and business information. Enhanced device performance OS updates are not only about security but also about enhancing the functionality and usability of your device.

How do I know if a software update is safe?

Real software updates should not require you to click on ads or provide personal information in pop-up windows. If you encounter a pop-up that asks for your credentials or personal information, it's likely a scam. If you receive an email claiming to provide software updates, check the sender's email address carefully

How does a computer work:

 A computer is a machine composed of many computer hardware and software components, each playing a unique role. A computer works by receiving data through an input unit based on the instructions it is given and after it processes the data, it sends it back through an output device. The final price of a computer should be from 1000$ to 4000$

Sound card

 A sound card is a computer component responsible for generating and recording audio. It enables users to connect analog speakers, headphones and microphones to their computer. Most modern computers have a built-in sound card in the motherboard. Generating audio on computers is challenging because sound is fundamentally analog, while computers are digital devices.

Motherboard

A complete computer components list always starts with the motherboard, the primary circuit board that holds all the hardware in place. Every PC has one, from dedicated workstations to personal notebooks. A robust motherboard offers many slots for installing multiple computer components (e.g. RAM, graphics card, etc.)

Motherboards offer different form factors, and only specific motherboard models can fit into certain computer cases/chassis, especially for customisable desktops.
