EXPLANATION

collisions are a normal characteristic of networks. You cannot stop all collisions from occurring, as that would be unrealistic. A better goal is to try to minimize that number of collisions that take place. To do so, you need to divide your Ethernet segment into smaller collision domains, which will result in fewer hosts per collision domain. To accomplish this, you have to use a switch. Every switchport has its own collision domain. This means that if you connect, for example, four hosts to four different switchports, you will have four collision domains
