Unit 1 - B3 Lesson 22-Bandwidth-Latency-and-Compression

What is the purpose of learning about bandwidth and latency?

• To improve data security

• To enhance data transmission speed

• To reduce data storage

• To increase user access

What is bandwidth in a network?

• The amount of data that can be transferred in a given period of time

• The time it takes for a data packet to transfer over a network

• The number of devices connected to a network

• The speed of a single data packet

In an analogy of bandwidth and traffic on the roads, what does "increasing the number of lanes" allow?

• More cars to travel at once

• Faster cars

• Fewer accidents

• Better road signs

In online gaming, which factor is more important?

• Bandwidth

• Latency

• Storage

• Resolution

What is required for applications where a lot of data needs to be transferred?

• High latency

• High bandwidth

• Low storage

• Low resolution

What is the main concern when little data is being transferred but needs to be transferred quickly?

• High bandwidth

• Low latency

• High storage

• Low resolution

Why is compression commonly used in data transmission?

• To make files more complex

• To transmit data faster across a network

• To increase download time

• To make files unreadable

What is one effect of lossy compression on images?

• Increases the number of colors used

• Reduces the number of colors used

• Enhances image quality

• Converts images to grayscale

What is an example of lossy compression as described in the image?

• An apple with different shades of green and brown when zoomed in.

• A perfectly clear image of an apple at all distances.

• An apple that changes color when viewed from different angles.

• An apple that remains the same color regardless of zoom.

How does audio and video compression work according to the text?

• By adding more data to the file

• By identifying and removing unnecessary data

• By increasing the file size

• By enhancing the sound and picture quality
