Spam is an act of sending messages through electronic devices repeatedly, without the request or will of the recipient.
Spam actions that usually occur are via email ( email ) containing advertisements, SMS from cellphones or also on a website.
In the following, We will explain what spam is, and how this spam can occur. Immediately see the article below Guys!
DEFINITION OF SPAM
Actions like this usually harm the recipient, because he did not ask for it. People who do this spam are also known as Spammers, and their actions are known as Spamming.
This spam is sent by advertisers at a very low cost because it does not require a mailing list to reach the desired customer.
The number of Spammers that appear occurs because barriers to entry are low, so the number of unsolicited messages becomes very high.
Because of this incident, many parties feel disadvantaged. Both the internet users themselves (ISPs) and the general public.
It turns out that this spam includes negative actions that can violate the law in internet laws.
Forms of Spam
There are many forms of spam that you must recognize from various electronic media, so you must be more vigilant and increase security to avoid this spam.
Even though it only contains advertisements or the like, this spam is also detrimental to internet users themselves.
It could be that the advertisement or spam message contains a virus or the like that can harm you.
Get to know some of the most common forms of spam, namely:
1. Email (Electronic Mail)
These spam messages usually go to junk mail or unsolicited commercial electronic mail.
Spam that often occurs in this email has been around since the 1930s.
Until now, the growth of spam in the electronic world is very high, reaching 80% to 85% of all electronic mail in the world.
Spam actions that usually occur in e-mails (e-mails ) are indeed the most common.
2. Instant Messaging
The instant messaging system itself can be used as spam.
According to a report from Ferris Research, 500 million instant message spam was sent in 2003, more than in 2002.
This instant spam is not blocked by the firewall, so many spammers take advantage of it.
3. Usenet Newsgroups and Forums
Spam newsgroups are the type that targets Usenet Newsgroups. This type actually existed before spam in electronic mail.
Uniquely, this type is often entered repeatedly with the same message substance.
If the type of forum spam, usually in the form of advertisements or the like that goes into internet forums. This action is performed by automated spambots that are set up.
This type usually consists of a message containing a link to a site, to increase search engine visibility in competitive areas.
Based on geographic area, this spam already exists around the world and is divided into various countries.
According to Cisco System data collection, in 2009 about the amount of spam in 5 major countries, namely:
That’s the understanding of what spam is and the highest number in several countries according to the Cisco System data collection that you should know Guys!
Hopefully, the above article can be helpful and useful for all of you guys! Thank you.
What is a router, it’s very important for you to know!
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.
Difference Between Laptop and Notebook
The difference between laptops and notebooks is not that significant, guys, but one of them has quite high mobility, you know!
A laptop is a portable computer that typically weighs 4-8 pounds (2 to 4 kilograms), depending on screen size, hardware, and other factors. Notebooks are personal computers that neglect several functions in order to remain light and small.
Notebooks usually weigh less than 5 pounds and are small enough to easily fit in a backpack or briefcase.
THE HISTORY OF THE EVOLUTION OF LAPTOPS AND NOTEBOOKS
In 1976, the Xerox PARC division developed the Xerox NoteTaker, which is considered the first portable computer.
It never reached the market, as only 10 prototypes were made. In 1981, the Osborne 1 was launched as the first commercially available portable computer.
It’s the size of a sewing machine table, you guys, wow. This Osborne does not have battery power, it only runs on direct electricity.
Notebooks are so-called because the size of these devices is roughly the size of a notebook. Named after NEC UltraLite 1988 and Compaq LTE, released in 1989.
This design was later combined with the IBM ThinkPad, featuring the first 10.4-inch screen in a notebook computer.
While these early notebooks averaged a little over 6 pounds, the lighter and more powerful “sub-notebooks” and in 1993 introduced the Gateway Handbook and the Hewlett-Packard OmniBook.
So basically the difference between this laptop and notebook is mainly from its size and functionality, guys.
Laptops are bigger and have many complete functions that you can get, while Notebooks are smaller and have many features that are trimmed from Laptops.
CONCLUSION DIFFERENCES LAPTOP AND NOTEBOOK
Initially, laptops were made to emulate the functionality of a desktop. However, the demand for laptops for entertainment purposes has driven the development of more compact devices, such as tablets.
Notebooks are also designed to function similarly to desktops but are geared more towards personal use than business use.
The practical size of a notebook is what defines it as a notebook. When it was first released, it didn’t even have a swappable hard disk or other related peripherals.
What is Email?
What does E-mail mean?
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.
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:
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!
