File Types
This file type is a compressed format ideal for web use with smaller file sizes. But, it's compression can reduce image quality.
.jpg
Define Lossy Compression
Permanently removes some of the original data, usually redundant information, to reduce file size.
What is an Audio Cable?
Audio cables are specialized to carry sound signals between devices, ensuring clear transmission of audio without interference.
What is Binary Code?
Where is Mr. Nevins' dream vacation?
Ireland
This file type is compressed audio with small file size and good quality. However, it has lossy compression reduces audio fidelity.
.mp3
Define Lossless Compression
Reduces file size without removing any data, so the original file can be perfectly reconstructed.
What is a Video Cable?
Visual cables, or video cables, are designed to transmit image data from a source device to a display.
What is a Digital Signal?
Digital Signals, on the other hand, represent data using discrete binary values, typically 0s and 1s, forming square waves rather than smooth, continuous curves.
Which video game franchise does Mr. Nevins like the most?
Persona, Uncharted, Mortal Kombat, or Mario Kart
Uncharted
This file type is a high-quality, uncompressed audio. However it is a large file size.
.wav file
Define Intra Frame Compression.
Intra-frame means that all the compression is done within that single frame and generates what is sometimes referred to as an i-frame.
Which of the following cables is considered a Dual-Purpose Cables?
XLR Cable, VGA, RCA, or DVI
RCA Cable
What is an Analog Signal?
Analog Signals are continuous waves that vary smoothly over time to represent data, closely mirroring natural phenomena like sound or light.
What are the uses for a GIF?
Entertainment
Communication
Marketing
Education
Web Design
Social Media Engagement
This file type, file allows for creating dynamic, interactive presentations with support for multimedia elements, animations, and custom layouts. However, opening and editing these files typically require software like Microsoft PowerPoint or compatible alternatives, which might not be universally accessible.
.pptx file
Define Inter Frame Compression.
Inter-frame refers to compression that takes place across two or more frames, where the encoding scheme only keeps the information that changes between frames.

Define Frequency
This is the number of cycles or wave peaks that pass a given point per unit of time, usually measured in Hertz (Hz).
What is the difference between AM and FM radio?
The key difference between AM and FM radio is that AM (Amplitude Modulation) varies the signal strength (amplitude) to transmit audio, while FM (Frequency Modulation) varies the frequency of the carrier wave for transmission, resulting in higher sound quality and less susceptibility to static.
This file type offers excellent compression ratios and supports error recovery, making it ideal for efficient and secure file storage. However, extracting these files requires specific software, which may not be as universally available as other formats like .ZIP.
.rar file
What is the difference between a Codec and a Container?
A codec is a technology used to encode or decode digital media files, compressing and decompressing audio or video data for efficient storage or transmission. A container is a file format that bundles encoded audio, video, and other elements (like subtitles) into a single package.

Define Amplitude
This is the maximum displacement or distance moved by a point on a wave from its equilibrium (rest) position.
What US city was Mr. Nevins' favorite to visit that ISN'T in the Tri-State Area?
New Orleans
