Datacom

Okay, let's think about datacom like sending a letter. Imagine you want to send a letter to your friend who lives far away. In order to do that, you write what you want to say on a piece of paper, put it in an envelope, write your friend's address on it, and then put it in the mailbox. The postman will come and take the letter from the mailbox and bring it to your friend's mailbox near his house.

Datacom works in a similar way, but instead of a letter, we're sending information or data. The information can be in the form of pictures, videos, text, or any other digital form. We use special tools or devices to send this data, like computers, smartphones, and tablets.

When we send the data, we need to make sure that it goes to the right place. So, we use addresses like email addresses, IP addresses, or phone numbers to make sure the data gets to the right person.

Just like the postman, there are special devices called routers or switches that help us send the data from one device to another. These devices are like traffic controllers that direct the data to the correct address. They make sure the data doesn't get lost or mixed up with other data.

Finally, when the data reaches its destination, it can be read or viewed on the receiving device. The whole process from sending to receiving is called data communication or datacom.
