CompTIA A+ Certification Core 1 (220-1101) - Hubs Versus Switches

The video tutorial explains the differences between hubs and switches in a local area network. It begins with an introduction to network boxes and their role in creating a LAN. The tutorial then distinguishes between hubs and switches, highlighting the functionality and limitations of hubs, such as shared bandwidth and slower communication. It concludes by demonstrating the advantages of switches, which include efficient data handling and improved network performance.

What is the primary purpose of the small boxes used in a local area network?

• To provide internet access

• To store data

• To connect computers within a network

• To amplify signals

How does a hub handle data transmission between computers?

• It repeats the signal to all connected devices

• It stores data temporarily before sending

• It sends data only to the intended recipient

• It amplifies the signal to all devices

What is a major drawback of using a hub in a network?

• It only supports wireless connections

• It shares bandwidth among all devices, slowing down communication

• It limits the number of devices that can connect

• It requires complex configuration

How does a switch improve network efficiency compared to a hub?

• By amplifying signals

• By learning and using MAC addresses to direct traffic

• By storing data for later transmission

• By providing internet access

Why are switches preferred over hubs in modern local area networks?

• They support only wireless connections

• They are cheaper to install

• They require less power

• They allow multiple conversations without bandwidth sharing
