A router is a physical or virtual device that provides information between two or more packet-switched computer networks.

Or like this Guys, a router checks the destination Internet Protocol address (IP address) of a particular data packet, calculates the best way to reach its destination and then forwards it according to that data Guys.

This tool is rich in almost every office now there must be, eh, maybe even in every house too, right?

HOW ROUTERS WORK

How it works connects your devices to each other and, in the programmed connection settings, to the modem.

This device connects to your modem and then to your device (laptop, smart TV, printer, etc.) via an Ethernet cable or, in the case of a wireless router, a WiFi signal.

This tool creates a local area network (LAN) within your home, allowing your devices to share files and peripherals such as printers. it also manages all incoming and outgoing information from each device and modem and ensures that everything is working properly.

But this tool does not need to be connected to a modem to function Guys. You can choose to create a LAN without Internet access.

In short, this is the function of the router guys:

• Assign a local IP address for each device on the network
• Create a firewall to prevent security breaches
• Manage traffic on the network
• Handling Parenting Controls

Well, it turns out that this modern tool is really important, guys. Without this device, you can’t reach the digital world that is very informative at this time.

Email is an abbreviation of electronic mail, which is known as electronic mail (email) in English. However, the word e-mail is more familiar to the public than e-mail.

Electronic mail has the same general functions as a conventional mailbox. Conventional mail is used to receive physical letters, while e-mail is used to receive electronic letters ( e-mail ).

In the following, We will explain what e-mail or e-mail is that is often used by modern society today.

UNDERSTANDING EMAIL

This e-mail or electronic mail serves to send a message in various forms. Such as in the form of text, images, files, audio, video and others via the internet.

Actually, this electronic mail has been used since 1960, but at that time there was no internet network, so there were only a collection of mainframes that formed a network.

This mainframe is a large computer in ancient times and is often used to process data and applications.

History of E-mail

Ray Tomlinson is the person who put forward the concept of electronic mail in 1971. At that time he worked at a company Bolt Beranek and Newman.

The company is an American state defence agency with a computer program called SNDMSG.

A program that is usually used to leave messages on a computer, so everyone who uses the computer will read the messages left behind.

Then Ray Tomlinson conducted an experiment by connecting SNDMSG to a protocol called CYPNET, which was still within the scope of an ARPAnet network.

The first message that was sent by Ray via electronic mail was QWERTYUIOP. Then in 1972, he introduced the @ symbol (read et) which symbolizes the identity of the email to this day.

Currently, there are several electronic mails or email providers that are familiar and very well known in the community.

This is a list of free e-mail service providers available on the internet:

• Gmail.com
• Yahoo.com
• Outlook.com

That’s an explanation of what e-mail is or the e-mail that we now use to send messages over the internet. Hopefully useful Guys!

Difference between chip and magnetic ATM cards is a must for you to know Guys! Because in the future magnetic-based ATM cards will be abolished.

what are the differences between the two versions of ATM? Here our team provides an explanation for you.

DIFFERENCE BETWEEN CHIP AND MAGNETIC ATM CARDS

1. Physical Differences

• ATM Card Chip = Has a chip on one side of the card, which serves to store all information related to your bank account.
• Magnetic ATM Card = As the name implies, the workings of a magnetic-based ATM card use a black strip, which can be called a Magstripe. The use of the ATM card can be swiped on an EDC machine.

2. Security

• ATM Card Chip = Equipped with a technology called Cartography, which is very safe. Then, the data embedded on the chip will not be duplicated.
• Magnetic ATM Card = The security system is still very weak and prone to crime. In addition, customer data stored on Magstripe can be easily duplicated by irresponsible parties.

3. Card Authenticity Check

• ATM Card Chip = If you have upgraded from the magnetic version to the chip version, then the authenticity of your ATM card can be checked using the Offline CAM and Online CAM methods.
• Magnetic ATM Card = For the magnetic version of the ATM card, the authenticity of the card you have cannot be checked, because the Host Bank terminal is not capable of doing this.

HOW TO SWITCH TO A CHIP-BASED ATM CARD

For how to change your old ATM card to the chip version, you just have to go to the nearest bank office in the area where you live.

Don’t forget to bring your old ATM card, passbook, and ID card. After that, you just have to submit the files to Customer Service and wait for a few minutes.

If you have, you will immediately get the latest chip-based ATM card and your old ATM card will no longer be able to be used.

That’s it Guys the difference between chip and magnetic ATM cards. How? Do you understand? If so, you should immediately go to the nearest bank office, so that the bank can process it immediately.

The plan is that all Banks in India can change all types of ATM cards for their customers no later than the beginning of 2022.
