(i) Drawing elements (or) objects such as lines, rectangles, circles and so on to create an images are based on Vector images.
(ii) The advantage of vector image is relatively small amount of data is required to represent the image and thereby only less memory is needed to store.
(iii) Compression techniques is used to reduce the file size of images that is useful for storing large number of images and speeding transmission for networked application.
E.g.: GIF, TIFF and JPEG.

Pre-production: Based on the planning and design, it is necessary to develop the project.
Budgeting: Budgeting for each phases like consultants, hardware, software, travel, communication and publishing is estimated for all the multimedia projects.

(i) TGA is the first popular format for high resolution of images.
(ii) TGA is supported by most of the video-capture boards.
(iii) PNG- An extensible file format for the less loss, portable and well compressed storage of raster images.
(iv) PNG acts as replacement for GIF and also replaces multiple common uses of TIFF
(v) PNG works good with online viewing applications like worldwide web. So, it is fully streameable with a best display option.

(i) JPEG was designed to attain maximum image compression.
(ii) It uses lossy compression technique, where a compression method is referred that loses some of the data required for the image reconstruction.
(iii) It works good with photographs, naturalistic artwork, and similar material but functions less on lettering, live drawings or simple cartoons.

(i) GIF is a compressed image format. Most of the computer color images and backgrounds are GIF files.
(ii) This file format is best suitable for graphics that uses only limited colors, and it is the most popular format used for online color photos.
(iii) 13-bit Color look up table is used by the GIF format to identify its color values. This format is supported widely.

(i) Initially this format is in use with Windows 3.1.
(ii) It is quite large and uncompressed and hence BMP is used for the high-resolution (or) large images.
(iii) This DIB format which is similar to BMP, allows the files to be displayed on a variety of devices.

This format is common in desktop publishing world (high quality output), and is supported by almost all software packages. Recent versions of TIFF allows image compression, and the format is comfortable for moving large files between computers.

(i) Sampled sound is a Digitized sound. A sample of sound is taken and stored every nth fraction of a second as digital information in bits and bytes.
(ii) The quality of this recording depends on the sampling rate. Sampling rate is defined as how often the samples are taken and how many numbers are used to represent the value of each sample (bit depth, resolution and sample size).
(iii) Finer the quality of the captured sound and the resolution is achieved while played back, when more often the sample is taken and the more data is stored about that sample.

(i) The common and comprehensive form of storing images in a computer is raster (or) bitmap image.
(ii) Bitmap is a simple matrix of the tiny dots called pixel that forms a raster (or) bitmap image. Each pixel consists of two (or) more colors.
(iii) Based on how much data, in bits is used to determine the number of colors, the color depth is determined.
E.g.: One bit is two colors, four bits means sixteen colors, eight bits indicates 256 colors, and so on.

Multimedia conferencing or video conferencing is a system that performs face-to-face interaction samong participating users, located far from each other, as if they weresitting and discussing in a single room.

(i) Multimedia is available in many public places like trade shows, libraries, railway stations, museums, malls, airports, banks, hotels and exhibitions in the form of kiosks.
(ii) The information presented in kiosk are enriched with animation, video, still pictures, graphics, diagrams, maps, audio and text. Banks uses kiosks in the form of ATM machines.

(i) Medical Students practices surgery methods via simulation prior to actual surgery.
(ii) Tiny digital cameras are inserted in human body and it displays the inner scene of the body. Like wise, the medical practioners were able to see the inner part without dissecting it.

(i) The remarkable advancement in the entertainment industry is due to the Multimedia Technololgy mainly.
(ii) This technology is needed in all mode of entertainment like radio, TV, online gaming, video on demand etc.
(iii) Video on demand or movies on demand is a service that provides movies to television sets ib an individual basis at homes.
(iv) Movies are stored in a central server and transmitted through a communication network.

(i) Multimedia plays a vital role in offering an excellent alternative method to traditional teching by allowing the students to explore and learn various concepts through animation.
(ii) Students, teachers and the parents enjoy this multimedia mode of learing and multimedia learning materials.
(iii) Many educators accept multimedia introduces new ways of thinking in the classroom.

(i) A hypertext is a system which consists of nodes, the text and the links between the nodes, which defines the paths the user; need to follow for the text access in non-sequential ways.
(ii) The author of the working system created this structure. The user is permitted to define their own paths in more sophisticated hypertext systems.
(iii) The user is provided with the flexibility and choice to navigate in hypertext.
