Hub and Switch Functionality

The video tutorial explains the concept of a hub in network infrastructure, describing it as a multidirectional repeater that broadcasts messages to all connected devices, similar to a loudspeaker. It uses a real-life analogy of a lost child announcement in a shopping center to illustrate how a hub functions. The tutorial then introduces switches, explaining their role in directing data more precisely compared to hubs, akin to a switchboard operator in a telephone network.

What is the primary function of a hub in a network?

• To store data

• To direct data to specific devices

• To repeat signals in multiple directions

• To encrypt data

In a star network, where is the hub located?

• At the edge of the network

• In a separate network

• Outside the network

• In the center of the network

How does a hub handle a message it receives?

• It broadcasts the message to all connected devices

• It deletes the message

• It sends the message to a specific device

• It stores the message

What real-life analogy is used to describe a hub's operation?

• A text message

• A private conversation

• A loudspeaker announcement

• A telephone call

What is the main difference between a hub and a switch?

• A switch can store data

• A switch can control the direction of data flow

• A hub can encrypt data

• A hub is faster than a switch

What is a switchboard in the context of a telephone network?

• A tool for encrypting phone calls

• A machine that records conversations

• A system that connects calls to the correct recipient

• A device that stores phone numbers

How does a switch determine where to send data?

• It uses a predefined path

• It sends data to all devices

• It directs data based on the destination address

• It randomly selects a device

What analogy is used to describe the function of a switch?

• A loudspeaker announcement

• A rail track switch

• A loudspeaker

• A storage box

Which device is more efficient in directing data to specific destinations?

• Repeater

• Router

• Switch

• Hub

What is the role of an operator in a switchboard?

• To encrypt calls

• To store messages

• To connect calls to the correct recipient

• To broadcast messages
