Hello students Welcome to CSE Study247 , In this page provide you Multimedia MCQs-3 , that contain 20 Multiple Choice Question.
Q.1 How many space reduce in lossless method?
40%
50%
70%
None
Explanation
Lossless compression algorithms generally reduce the size of a file by approximately 50%, though this varies based on the redundancy of the original data.
Q.2 Which of the following reason for applying the compression?
To reduce storage
To reduce Processing time
Both A & B
None
Explanation
Compression is used to save disk space (storage) and to speed up data transmission and processing by reducing the total volume of data.
Q.3 ——– Technique is generally useful for us when the quality of data is not our first priority?
Loss
Lossless
Both A & B
None
Explanation
Lossy (Loss) compression is ideal when extreme file size reduction is more important than maintaining a perfect, bit-for-bit replica of the original.
Q.4 In this type of VR environment, the three-dimensional scene is considered as a part of the physical environment.
Immersive
Semi immersive
Non immersive
Augmented
Explanation
Non-immersive VR allows the user to view a 3D environment on a standard monitor while remaining fully aware of their actual physical surroundings.
Q.5 Video is represented as a series of images formally known as
Frames
Snaps
Pics
None
Explanation
Frames are the individual still images that, when played in rapid succession, create the appearance of motion in a video.
Q.6 A type of VR environment in which subjects are visually isolated from the real environment
AR
Non immersive
Semi immersive
immersive
Explanation
Immersive VR uses specialized equipment like Head-Mounted Displays (HMDs) to completely block the real world and surround the user with a digital one.
Q.7 A concentric ring on a disk is referred to as a?
Sector
Track
Table
Segement
Explanation
On a hard drive or floppy disk, a track is one of the many concentric circles on the surface of the platter where data is stored.
Q.8 MPEG-1 was designed for a?
CD
PC
Floppy
DVD
Explanation
MPEG-1 was originally developed to provide video and audio compression for Video CDs (VCDs) at a bitrate of about 1.5 Mbps.
Q.9 Which compression provide some loss of quality
Loss
Cell based
Object based
Lossless
Explanation
Lossy (Loss) compression achieves smaller file sizes by permanently removing data that the human eye or ear is less likely to perceive.
Q.10 is a shorthand representation of music stored in numeric form
Digital audio
MIDI
LPC
Mono File
Explanation
MIDI (Musical Instrument Digital Interface) stores musical data as a series of commands (pitch, duration, etc.) rather than a recording of the actual sound waves.
Q.11 The first phase of JPEG is
DCT transformation
Quantization
Data compression
None of these
Explanation
The JPEG process begins with a Discrete Cosine Transform (DCT), which converts pixel data from the spatial domain to the frequency domain.
Q.12 The second phase of JPEG is
DCT transformation
Quantization
Data compression
None of these
Explanation
Quantization is the stage where the frequency coefficients are divided by a constant, resulting in the actual loss of data that makes the file smaller.
Q.13 The third phase of JPEG is
DCT transformation
Quantization
Data compression
None of these
Explanation
The final phase of JPEG involves using an entropy coding method (like Huffman coding) to compress the remaining data as efficiently as possible.
Q.14 The human eye measure the loss of data.
True
False
Both A & B
None of these
Explanation
Lossy compression works because the human eye and brain are incapable of perceiving the specific data points that the algorithm discards.
Q.15 —- is an application that allows you to to send and receive messages over cell phones
MMS
Multimedia
Micromedia
None of these
Explanation
MMS (Multimedia Messaging Service) is the standard protocol used to send messages that include images, video clips, or audio over cellular networks.
Q.16 With reference to multimedia elements, pick the odd-one out of the following
Animation
Audio
Voice Script
Video
Explanation
Animation, Audio, and Video are core digital media components, whereas a ‘Voice Script’ is a textual blueprint used during production.
Q.17 Random access is not allowed in
Live streaming
Dead streaming
Static streaming
On demand streaming
Explanation
In live streaming, you cannot jump ahead (random access) because the data is being generated and transmitted in real-time.
Q.18 A term to describe the extent to which a user can modify form and content of a mediated environment.
Interactivity
Non Interactivity
Richness
None
Explanation
Interactivity refers to the degree to which a user can participate in or manipulate the digital content they are interacting with.
Q.19 AIFF Format was developed by
Apple
IBM
Microsoft
None
Explanation
AIFF (Audio Interchange File Format) was developed by Apple Inc. for use on Macintosh computers and is based on Electronic Arts’ IFF format.
Q.20 Lossy and lossless are classifications of
Files
Compression algorithms
Multimedia storage systems
None
Explanation
Lossy and lossless are the two fundamental categories of compression algorithms used to reduce the size of digital files.
