Near-Field Communication or NFC for short, is a set of communication protocols for connecting between two electronic devices at a distance of 4 cm or less, guys.
This is a wireless technology that is quite important thanks to the growth of online payment systems like Samsung Pay and Google Pay.
Especially when it comes to high-end devices and even a lot of mid-rangers right now are getting them too. You may have heard this term before, but what exactly is NFC?
As the name suggests, it allows close-range communication between compatible devices. This technology requires at least one transmitting device, and another to receive the signal. Various devices can use the NFC standard and will be considered passive or active.
Passive NFC devices include tags, and other small transmitters, which can send information to other devices without requiring their own power source.
HOW NFC WORKS
How does it work? Just like Bluetooth and Wi-Fi, and all kinds of other wireless signals guys. The technology works on the principle of sending information via radio waves.
This means that devices must adhere to certain specifications in order to communicate with each other properly.
The technology used is based on the old ideas of RFID (Radio-frequency identification), which uses electromagnetic induction to transmit information.
Nowadays, this technology feature is really needed, you know, especially for a payment!
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.
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
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.
Difference between WiFi and Hotspot
Many people don’t know the difference between WiFi and Hotspot, and it’s very clear that you often mispronounce the two terms.
WiFi itself is an abbreviation of Wireless Fidelity, a wireless internet network that uses radio waves.
Which allows computers, cellphones, televisions or printers to be connected with an internet connection.
While Hotspot is a term in English which means ‘signal area,’ so simply Hotspot is an area that has a wireless internet connection network or not.
Such as in the office, campus, home, etc.
The hotspot itself can connect an internet connection to various devices in that location, Guys.
From this explanation, you can already know the difference between WiFi and Hotspot?
That’s all we shared, of course, we will give you other interesting information about technology.
