Lossy compression is a type of data compression technique that provides some loss of quality. It achieves higher compression ratios by permanently removing some data that is considered less important or less noticeable to the human eye or ear. This means that when the compressed data is decompressed, there will be a loss of quality compared to the original uncompressed data. Object-based and cel-based compression techniques do not necessarily involve loss of quality, while lossless compression techniques aim to retain all the original data without any loss.

There are two types of video compressions.

Slides is the correct answer because it refers to a computer-based presentation technique. Slides are typically used in programs such as Microsoft PowerPoint to create visual aids for presenting information. They allow the user to display text, images, and other media in a sequential manner, making it easier to convey information and engage the audience during a presentation.

Lossy compressions provide some loss of quality because they use algorithms that discard certain information from the original data in order to reduce file size. This means that some details or data may be permanently lost during the compression process, resulting in a decrease in quality. Lossless compressions, on the other hand, do not result in any loss of quality as they are able to fully restore the original data after decompression. Cel based and object based compressions are not relevant to the concept of loss of quality in compression.

MMF stands for Multimedia System, which refers to a system that allows the integration of various types of media, such as text, graphics, audio, and video. This system is used for creating, storing, manipulating, and presenting multimedia content. It is commonly used in fields such as entertainment, education, marketing, and communication.

The correct answer is "Graphic Interchange File." GIF stands for Graphic Interchange File, which is a file format commonly used for images and animations on the internet. It supports both static and animated images and has become popular due to its small file size and ability to display transparent backgrounds.

The correct answer is 5 because sound is controlled by five main attributes: pitch, volume, tone, duration, and timbre. Pitch refers to the highness or lowness of a sound, volume is the loudness or softness, tone determines the quality or color of the sound, duration is the length of time the sound lasts, and timbre is the unique characteristic that distinguishes one sound from another. All these attributes work together to create different characteristics of sound.

The correct answer is GIF. GIF is a lossy format because it uses a compression algorithm that discards some of the image data in order to reduce file size. This results in a loss of image quality, especially for complex or detailed images. JPEG is also a lossy format, while MPEG and PNG are lossless formats, meaning they retain all of the original image data.

JPEG stands for Joint Photographic Experts Group. It is a commonly used file format for compressing and storing digital images. The correct answer is "Joint Photo Experts Group", which accurately represents the acronym JPEG.

The most commonly used image formats are JPEG (Joint Photographic Experts Group) and PNG (Portable Network Graphics). These formats are widely supported by various devices and platforms, making them the go-to choices for sharing and displaying images. Other formats like GIF (Graphics Interchange Format) and TIFF (Tagged Image File Format) are also commonly used, but not as extensively as JPEG and PNG. Therefore, the correct answer is 2.

The correct answer is "Morphing." Morphing is a technique used to blend two or more images together to create a new image. It involves smoothly transitioning between the different images, often by manipulating the shape and appearance of the objects or subjects in the images. This technique is commonly used in animation, special effects, and image editing software to create seamless transitions between different frames or images.

There are six categories of image file compressions.

The correct answer is 2 because creating a 3D animation typically involves two main steps: modeling and animating. In the modeling step, the objects and characters in the animation are created and shaped using specialized software. In the animating step, the objects and characters are given movement and brought to life through keyframe animation or other techniques.

Shockwave is a file format that is commonly used for creating interactive multimedia content, including images. It supports high-quality graphics and animations, making it suitable for creating a perfect reproduction of the original images. The other options, Nx View, GIF, and JPG, are also image file formats, but they may not necessarily provide the same level of reproduction quality as Shockwave.
