File Types and Internet Basics Flashcard

Front

What file type would be best for using photographic images with good quality and small file size on a website?

Back

JPEG

Answer explanation

JPEG is ideal for photographic images as it provides good quality with a smaller file size compared to GIF and PNG, which are better for graphics and transparency. SVG is vector-based and not suitable for photos.

Front

What file type would be best for creating a small animated “loading” spinner that loops continuously on a webpage? Options: GIF, PNG, JPEG, SVG

Back

GIF

Answer explanation

The GIF format supports animation and is ideal for creating small, looping animations like a loading spinner. PNG and JPEG do not support animation, while SVG is better for scalable graphics but not specifically for simple animations.

Front

What file type would be best for a company logo that requires a transparent background so it can be placed over various colours? Options: GIF, PNG, JPEG, SVG

Back

PNG

Answer explanation

The PNG file type supports transparent backgrounds, making it ideal for logos that need to be placed over various colors. Unlike JPEG, it retains quality with transparency, and while GIF also supports transparency, PNG offers better color depth.

Front

What file type would be best for a responsive website logo that must remain perfectly sharp when scaled from small to large sizes?

Back

SVG

Answer explanation

SVG is the best file type for a responsive website logo because it is vector-based, allowing it to scale without losing quality. Unlike raster formats like GIF, PNG, and JPEG, SVG maintains sharpness at any size.

Front

A website needs short sound effects that should load quickly but maintain high sound quality for music samples. Which file type is most suitable? Options: WAV, MP3, MIDI, AAC

Back

MP3

Answer explanation

MP3 is the most suitable file type as it offers a good balance between sound quality and file size, allowing for quick loading while maintaining high quality for music samples. WAV files are larger, and MIDI is not suitable for sound effects.

Front

File type suitable for preserving full quality of a live concert recording for professional audio editing: WAV, MP3, OGG, MIDI.

Back

WAV

Answer explanation

WAV files are uncompressed and preserve the full quality of audio, making them ideal for professional editing. In contrast, MP3 and OGG are compressed formats that reduce quality, and MIDI is not an audio file type.

Front

A small background music loop for a web game must have a very small file size and only basic sound quality. Which file type is most suitable? Options: WAV, MP3, MIDI, AIFF

Back

MIDI

Answer explanation

MIDI is the most suitable choice for a small background music loop as it generates music using digital signals rather than audio samples, resulting in a very small file size and basic sound quality, ideal for web games.

Front

A live sports streaming service needs a format that can deliver real-time broadcasts with minimal delay and efficient packet handling. Which protocol/file type is most suitable?

Back

RTSP

Answer explanation

RTSP (Real-Time Streaming Protocol) is designed for real-time streaming applications, providing low latency and efficient packet handling, making it the best choice for live sports streaming compared to HTTP MP4, AVI, or MOV.

Front

A training video will be embedded on a webpage and must be viewable in all modern browsers without plugins. Which file format is most suitable?

Back

MP4

Answer explanation

The MP4 format is widely supported across all modern browsers without the need for plugins, making it the most suitable choice for embedding videos on a webpage. Other formats like WMV, FLV, and MKV may not be universally compatible.
