Messages from Broadcast They seek to optimize the work of servers, in addition to helping users by saving time when sending messages. But what are broadcast messages? That's what we'll see next.
What are Broadcast messages?
Broadcasts are text messages sent to more than one person at the same time, with purposes that will be defined in advance, aiming to reach the largest number of people in a short space of time.
Basically, in the world of computer networks, we assume that the broadcast address is one that when addressed will transmit the information to all hosts on its respective network.
For example, if a packet's destination is 10.255.255.255, a copy of each packet will be sent to every possible address on network 10, totaling many packets. And by default, the broadcast address of any network will always be its own last valid address.
What are Broadcast messages for?
In English terms, broadcast means transmission or diffusion. It is widely used to transmit a large amount of messages to all devices that are connected to that network and most of the time, it serves as a strategy marketing attracting customers to company promotions.
In addition, these messages are also used to transmit emergency alerts to users about floods, fires, hurricanes, among others. For example, for those who live in risk areas, it is a highly relevant resource, and it is recommended that customers do not deactivate it.
Can I disable broadcast messages?
Although important, these messages tend to be quite irritating precisely because they also function as marketing strategies operators, which makes many customers want to deactivate them and this is possible, however, as we have already said, if you live in risk areas, it is not recommended.
But if this is not your case, deactivating these messages is done in a very simple way, varying according to the manufacturer, let's see:
Disable broadcast messages on Android
- Click on the “messaging” app on your Android smartphone;
- Then, press the “menu” button on your smartphone and/or tap on “settings” in the messages;
- Click on “CB settings”, and change the “CB activation” option.
- Done, messages will be disabled!
Disable broadcast messages on iPhone
- Click on the messages icon, then settings and preferences, text/SMS messaging options.
- Then, simply deactivate it, so that you stop receiving emails/broadcast.
- You can also do this through your carrier's website.
- Using iMessage, starting with iOS 7, click on the letter “i” next to the name of the contact who sent the message to block them.
- Done, messages disabled!
Disable Broadcast Messages on Windows Phone
- Go to your device's settings, and click on call/SMS filter.
- After that, switch it to “enabled”.
- Then, click on the number that sent you the message, until it is blocked on your device!
- Ready!
It is worth remembering that it may be necessary to block more than one number to stop SPAM broadcast.
What methods of message transmission exist?
There are three methods:
1: Unicast Messages: These messages occur when a device communicates directly with another device, always one at a time, unlike broadcast, for example, which communicates with several devices at once.
Therefore, when this occurs, only the device used as the recipient will receive the messages, the others will not be able to hear, or should not be listening to this type of conversation, hence the name Unicast, from unique.
Examples of protocols that are used for unicast transmissions include HTTP, SMTP, FTP, and Telnet.
We will use this Unicast mode, for example, when we are exchanging files with another computer.
2: Broadcast Messages: As we mentioned above, it is a form of communication in which a message is sent from one computer to all others connected to the network.
In this case, all the people who hear this message at the same time, we call it the broadcast domain.
For example, when there is a file that more than one computer needs to access, then, in this case, the ideal would be to use broadcast mode.
3. Multicast Messages: This is another form of network communication, which is when a single device talks to a group of devices. Then, the conversation will only occur with people who are in the same group, which will then be a private transmission.
Therefore, a device, which can be a computer, tablet, among others, transmits the message, and only this private group will be able to hear these messages, the other computers will not receive the message that was sent to that group, precisely because they are not connected to it.
What are the message addressing methods?
1: Unicast Addressing: The addressing of unicast messages must be for a specific sender, and this type of message transmission is considered one of the most used, and is present in almost all existing protocol models.
2: Broadcast Addressing: The Broadcast transmission method occurs when a tablet, for example, sends messages to others that are on the same network, therefore, its addressing must be restricted to that specific network, being a rare addressing.
3: Multicast Addressing: The Multicast transmission method occurs when a single computer, for example, sends messages to others that are on the same network, therefore, its addressing requires means of identification for a specific group that will be able to hear these messages.
Therefore, these methods of transmitting and addressing messages aim to facilitate the work of these servers.
