Answer:
Switches break up collision domains and routers break up broadcast domains.
Explanation:
- Collision domain depicts the part within a network where a collision can happen.
- Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
- Too many collisions can result in slow traffic speed and can effect network performance.
- So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
- When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
- Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.
- Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
- Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
- Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.
The answer that is a record in a relational database is called; A row
<h3>What is a record in relational database?</h3>
In relational databases, a record is defined as a group of related data held within the same structure. Furthermore, we can say that a record is a grouping of fields within a table that reference one particular object.
Now, in relational database, a row is called a record because each row, contains a unique instance of data or key for the categories defined by the columns.
