What is GPS and how does it work

GPS stands for Global Positioning System; it is a navigation system that uses satellites, receivers and algorithms to synchronize location, speed, and time data for air, sea, and land travel.

The satellite system consists of a constellation of 24 satellites in six orbital planes centred on Earth. Each with four satellites orbits at an altitude of 13,000 miles (20,000 km) above Earth and travels at 8,700 mph (14,000 km/h).

While we only need three satellites to produce a location on the Earth’s surface. The fourth satellite is often used to validate the information from the other three Guys.

The fourth satellite also transports us to the third dimension and allows us to calculate the device’s height.

HOW GPS WORKS

GPS works through a technique called trilateration. Used to calculate location, speed and altitude, trilateration collects signals from satellites to produce location information. This is often misunderstood as triangulation, which is used to measure angles, not distances.

Satellites orbiting the Earth send signals to be read and interpreted by GPS devices located on or near the Earth’s surface. To calculate the location, the GPS device must be able to read signals from at least four satellites.

Difference between Spyware and Malware

Difference between Spyware and Malware

The difference between Spyware and Malware is sometimes. Still, many people think that these two are the same, even though they are very different.

In short, malware is a general term used to describe several types of malicious software, including adware, Spyware, trojans and others.

Spyware is a specific type of malware, but it is very different from most other malicious software.

THE PURPOSE OF SPYWARE AND MALWARE

Most malware is designed to harm your computer in some way. Many programs can accidentally damage your laptop, but malware’s sole purpose is to cause errors, slow down your computer, or spread viruses.

The purpose of Spyware derives from its name and is designed to monitor your actions. Spyware will see what sites you visit and, in more extreme cases, track what you type to steal your passwords and personal information.

The effect

Malware, such as viruses and trojans, will generally only cause problems on your computer—examples like slowing it down or generating an error.

Spyware collects your personal information and can cause more long-term damage by giving others access to your online accounts, bank information, etc.

How to prevent it

This can be transmitted in various ways such as:

  • From the websites, you visit.
  • The program you downloaded.
  • And the email you opened.

Because of this, they often have more entry points and can more easily infect your system.

And prevention requires using a firewall and ensuring your antivirus program can work in the background to detect it automatically.

Spyware can be more complicated to detect and may infect your system without your knowledge. Antispyware programs are more effective in the removal phase, not prevention.

Difference between 404: Not Found and 403: Forbidden

Difference between 404 Not Found and 403 Forbidden

The difference between 404: Not Found and 403: Forbidden is not significant. Guys, both are codes that indicate failure to access a website.

So if 404: Not Found, it is a code that indicates if the server failed to find any information related to the website/site you want to go to.

While 403: Forbidden is an error code that indicates if the site you are accessing does not display the data you want to access because some information on the site may be forbidden for many people to see.

Only if in 403: Forbidden the case can have a different meaning and become a protection for the website because basically, it can ward off foreign attacks that want to steal the site’s data.

But both are still detrimental to the website owner because obviously, the visitors will immediately leave your site.

If you are the owner of a website/site, you should avoid them, guys.

Yep, that’s the difference between 404: Not Found and 403: Forbidden; you should be able to start distinguishing the two, guys.
