Language does not always use spoken language, but also uses body language or sign language. You can imagine, if in the world there is no language, then we all cannot communicate with each other. But nowadays, spoken language is not everything. Because, many have created modern communication tools.
Language is indeed the main communication tool used by humans to interact daily. The language we know as colloquialism is conventional or convection. Thus, in this world there are hundreds to thousands of national and regional languages spread throughout the world. Language is the main means of communication. These modern communication tools are basically the same, namely to make it easier for humans to communicate.
Communication tools are also experiencing development. In ancient times, to gather people around to want to gather in a place or to notify other people if there is a danger, a gong was used. "Kentongan" (in Indonesia) is usually placed in the corners of the hamlet. So, if someone wants to share information, all they need to do is gather the community members and call the residents using a kentongan.
In addition to the gong, you can also use fire or a long blown trumpet. After kentongan and fire, humans then used animals to send letters. So that in ancient times, many kept pigeons which were used as letter carriers. In addition to pigeons, you can also use pets such as dogs and cats.
Now, times are advancing. Animal services have also been replaced by human services. The dove's job was replaced by a letter delivered by the postman. A few years ago, post boxes could still be found in several places in city centers or on the highway.
As the times progressed, the number of post boxes decreased. People's interest in sending letters by post began to decrease because they turned to other modern means of communication.
Postal services are now more used as work calls or companies that require mail delivery services. The postal service still has a lot of demand, namely the delivery of goods along with the number of people who sell via online. The following will describe several types of modern communication tools that have developed in society.
Telephone and Cellphone
The telephone that Alexander Graham Bell found, was still large and could not be carried anywhere. However, it is possible that there would not have been a variety of telephones had it not been invented by Alexander Graham Bell.
Before mobile phones or telephones were rampant as they are today, in the past it was very difficult to have this one communication tool, especially landlines. In the past, people who had telephones were only among the rich because the price was still expensive.
But at that time there were also public telephones installed in several public places to make it easier for ordinary people to communicate remotely. So, it could be that one Village only has one telephone.
Gradually, homes had their own personal telephones. After personal telephone, then began to spread "wartel" or telephone stalls and public telephones. So a dozen years ago, coins were still very valuable because they were used to make calls.
However, along with the development of technology, the existence of landlines and public telephones is increasingly being displaced by cellphones (mobile phones) or more popularly with the abbreviation Hand phone. Compared to telephones, cellphones are more popular and more preferred because they are more practical and easy to carry everywhere.
Hp was first introduced in 1973. This year, the form of Hand phone is still in the form of large and heavy bars. After that, he developed various shapes and sizes. Now, various cell phones from various brands are very easy to find in stores or outlets that sell cell phones.
Not only adults, even children are now familiar with cellphones. In fact, it becomes a personal item. Hand phone is a crucial thing and many people can't get rid of cellphones. This shows that the cellphone is an important communication tool.
In addition to making calls and sending messages, cellphones can also be used to open or send emails. Hand phone has provided various conveniences, so many people depend on this one communication tool.
Television
TV does not only act as a medium of entertainment, but also a medium of communication. A lot of information is displayed, such as information on loss, accident, search, sad news, health, movies, and much other information.
However, just like cellphones, TVs must be used wisely. Especially if the users of the technology are children. Parents must always supervise so that the communication tools provided by parents to children are not used for negative things.
TV also does not always have a positive impact on providing useful information. TV sometimes presents programs that often have a negative impact on children, such as shows that children should not watch and cartoons that teach children bad habits.
Radio
Radio is more flexible to enjoy than TV. Because to be able to listen to the radio, we do not have to spend time sitting in front of the screen. Simply by turning on the radio, we can still hear the radio, even though we are cooking or cleaning the house. Radio also often displays live news. So, listeners can immediately receive messages live.
Computers and the Internet
The internet is a communication medium that is widely used for various activities. For example, to search for information, download, watch, or communicate remotely.
The internet is like two sides of a coin, it can have a good or bad impact on its users, depending on the user's personality and intentions. Therefore, the internet must be used wisely because many people abuse the internet to see things that are prohibited.
Basically, this modern communication tool was created to help meet human needs. These tools have developed from time to time. So maybe in the next ten years, the existence of these tools will be replaced by more sophisticated tools, such as robots that help humans do all the work and help humans get the information they need.
