World of Computer Networking Your CCNA start - Collision Domains

The video tutorial explains collision handling in computer networks, focusing on collision detection and avoidance mechanisms. It introduces the concept of collision domains, highlighting how they define network areas where collisions may occur. The tutorial discusses the role of hubs, switches, and wireless access points in managing collision domains, emphasizing the differences in their impact on network performance. Hubs create large collision domains, while switches and wireless networks can limit the domain size, improving efficiency. The video concludes with a brief mention of how devices agree on speed and duplex settings.

What is a collision domain in a computer network?

• A network area that is free from any data collisions

• A part of the network where data packets are always successfully transmitted

• A section of the network where data collisions can occur

• A domain where all devices operate in full duplex mode

How do hubs affect collision domains in a network?

• They create multiple small collision domains

• They eliminate the possibility of collisions

• They operate on the data link layer to manage collisions

• They create a single large collision domain

Which layer of the TCP/IP model do hubs operate on?

• Network layer

• Application layer

• Transport layer

• Physical layer

How do switches help in managing collision domains?

• They create individual collision domains for each connection

• They create a single large collision domain for all devices

• They operate only on the physical layer

• They require all devices to operate in half duplex mode

In a wireless network, what mechanism is used to manage collision domains?

• Full duplex communication

• Half duplex communication

• Collision avoidance

• Collision detection
