Why does reducing image file size improve page speed?

Analyze why smaller image files help a webpage load faster.

A Smaller files require less data to download, speeding up load time.

B Smaller files improve the color quality of images.

C Smaller files reduce the number of images shown on the page.

D Smaller files increase the number of HTTP requests needed.

❓ Comparison

Which technique is more effective for improving page speed on mobile devices?

Compare these two methods: compressing images vs. deferring JavaScript loading. Which generally improves mobile page speed more?

A Neither affects mobile page speed.

B Compressing images because it reduces data size significantly.

C Both have equal impact on mobile page speed.

D Deferring JavaScript because it delays non-essential scripts.

💡 Hint

Consider how scripts can block page rendering on mobile.

Deferring JavaScript loading prevents scripts from blocking the page render, which often improves mobile speed more than image compression alone.

❓ Reasoning

What is the effect of enabling browser caching on repeat visits?

Explain how browser caching affects the loading speed when a user visits the same page multiple times.

A It speeds up loading by storing resources locally to avoid re-downloading.

B It has no effect on loading speed for repeat visits.

C It slows down loading because the browser checks for updates every time.

D It deletes all stored data after each visit.

💡 Hint

Think about how saving files on your device helps load pages faster next time.

Browser caching saves files locally so the browser can load them quickly without downloading again, improving repeat visit speed.
