Answer:
All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.
A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision
Explanation:
Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.
CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.

Database management system (DBMS) refers to software for creating, maintaining, and manipulating data.
In the field of software engineering, a database management system (DBMS) can be described as a software whose function is to properly manage a database. Any kind of data in a database can be created, changed, or retrieved through the database management system (DBMS).
It is through the database management system (DBMS) that data is created, gets secured and its integrity is maintained. Through the database management system (DBMS), a certain piece of data can be assessed by various people at the same time from different locations.
Some examples of database management systems are columnar DBMS, NoSQL DBMS, and in-memory DBMS.
