Answer 2

Answer:

Explanation:

Multimedia is a form of communication that combines different content forms such as text, audio, images, animations, or video into a single presentation, in contrast to traditional mass media, such as printed material or audio recordings. Popular examples of multimedia include video podcasts, audio slideshows, animated shows, and movies.

Multimedia can be recorded for playback on computers, laptops, smartphones, and other electronic devices, either on demand or in real time (streaming). In the early years of multimedia, the term "rich media" was synonymous with interactive multimedia. Over time, hypermedia extensions brought multimedia to the World Wide Web.

FEATURES-

Given the above challenges the following feature a desirable (if not a prerequisite) for a Multimedia System:

Very High Processing Power

-- needed to deal with large data processing and real time delivery of media. Special hardware commonplace.

Multimedia Capable File System

-- needed to deliver real-time media -- e.g. Video/Audio Streaming. Special Hardware/Software needed e.g RAID technology.

Data Representations/File Formats that support multimedia

-- Data representations/file formats should be easy to handle yet allow for compression/decompression in real-time.

Efficient and High I/O

-- input and output to the file subsystem needs to be efficient and fast. Needs to allow for real-time recording as well as playback of data. e.g. Direct to Disk recording systems.

Special Operating System

-- to allow access to file system and process data efficiently and quickly. Needs to support direct transfers to disk, real-time scheduling, fast interrupt processing, I/O streaming etc.

Storage and Memory

-- large storage units (of the order of 50 -100 Gb or more) and large memory (50 -100 Mb or more). Large Caches also required and frequently of Level 2 and 3 hierarchy for efficient management.

Network Support

-- Client-server systems common as distributed systems common.
