Graphics And Multimedia MCQ Quiz!

A multimedia system is characterized by both high storage and high data rates. This means that it is capable of storing and processing large amounts of data, such as videos, images, and audio files, while also being able to transmit and transfer this data at high speeds. This is essential for multimedia applications that require the efficient handling of large files and real-time streaming of content.

JPEG stands for Joint Photographic Experts Group. This is a commonly used image file format that uses a lossy compression algorithm to reduce the file size while maintaining a good level of image quality. The Joint Photographic Experts Group is the organization that developed this file format, hence the acronym JPEG.

The region code 0000 represents the Viewing Window. The viewing window is the area of the screen where the graphics or images are displayed. It is the portion of the screen that is visible to the user. The region code 0000 is often used to indicate the entire viewing window or the whole screen.

Multimedia is a computer-based presentation technique that involves the integration of various forms of media such as text, graphics, audio, video, and animation. It allows for interactive and engaging presentations that can be delivered through computers or other electronic devices. This technique enables the presenter to convey information in a dynamic and visually appealing manner, making it an effective tool for communication and education.

JPEG is a lossy image format because it uses a compression algorithm that discards some data in order to reduce file size. This compression can result in a loss of image quality, especially when the image is heavily compressed. GIF, MPEG, and PNG are not lossy formats. GIF is a lossless format that supports animation, MPEG is a lossy format for video compression, and PNG is a lossless format that supports transparency.

Morphing is a technique used to blend two or more images together to create a smooth transition between them, resulting in a new image. It involves transforming the shape and appearance of one image into another gradually, creating a seamless morph between the two. This technique is commonly used in various applications, such as special effects in movies, facial recognition, and image editing software.

Translation is the correct answer because it refers to the process of moving an object from one coordinate location to another in a straight line path. This involves shifting the object's position without changing its orientation or shape. Rotation involves turning an object around a fixed point, scaling involves changing the size of an object, and shearing involves distorting the shape of an object.

There are two categories of image file compressions.

Clipping is the correct answer because it refers to the process of dividing each element of a picture into its visible and invisible portions. The visible portion is retained, while the invisible portion is discarded. This technique is commonly used in computer graphics to ensure that only the visible parts of an object are displayed on the screen.

A smaller version of an image is commonly referred to as a thumbnail. Thumbnails are typically used as a preview or representation of a larger image, allowing users to quickly browse and select the desired image without having to load the full-size version. They are commonly used in image galleries, search results, and file explorers to provide a compact visual overview of the available images.
