The next process can also be easily examined according to the structured data, and the time is also saved. Moreover, we see that it also helps interpret and execute the data. As it ensures the integrity and helps to identify the methods.
Types of Database Management System
| Types | Description | Example |
|---|---|---|
| Hierarchical DBMS | In it, the data is organized in a tree-like structure. With the tree structure, you can organise and check the data as per your needs. | IBM IMS |

Data Communication & Networking
The data communication system is an exchange between the data of two or more devices. It helps in the transmission of data between the two media, such as wireless and cables. Through it, the data can be enabled between the two platforms, and they can use it effectively.
There are different market topologies like bus, star, ring, hybrid, and mesh. These different topologies consist of the system through which the message can be sent or received. With the help of these topologies, we can say that the message is transferred through a different structure.
In the Bus topology, the message can be sent through a single central cable. The message can be conveyed through the other person; only we can deliver the message.
The star topology is a system through which the devices get connected to a central hub. In the ring, devices are connected circularly. Like the message can be transformed between the systems.
The other topology is a mesh topology in which the data can be sent through the different devices. In it, every device can connect to send the information.
| Element | Description |
|---|---|
| Message | The actual data, like text, audio, video, etc., is being communicated through the message. In the message, there is complete information that must be delivered to another person. |
| Sender | The next is the device or person through which the message is available to the other person. It helps in sending the message. Through it, the sender and receiver can transmit their information. |
| Receiver | It is the device or person that receives the message. Through it, the receiver can get the message and can enable it to read. So, when the message become available, one can use it according to his needs. |
| Medium | It is a path through which the data travels from one medium to another. There are different options which help in transmitting the information. Some of the main information through which it can be transmitted are fibre optics, airwaves, and cables. |
| Protocol | It is a governing body that helps in data transmission. It consists of TCP and IP. To send the message, one must follow the protocol so that there will be no intermission in between sending the message. |
