Q 4: EXPLAIN THE BASIC CONCEPT OF MULTIMEDIA. IDENTIFY TEN DIFFERENT EXAMPLES OF MULTIMEDIA AND ALSO DESCRIBE FIVE OF THEM IN DETAIL.

Answer:
THE CONCEPT OF MULTIMEDIA:-
The term ‘multimedia’ refers to diverse classes of media employed to represent information. The unit provides the basic concepts of multimedia, multimedia elements and interactivity issues required for multimedia applications. Before the design take place, a topic from the syllabus was chosen for this multimedia application. This includes ensuring there are enough resources to building the application. Multimedia is the use of computers to present text, graphics, video, animation, and sound in an integrated way. Long touted as the future revolution in computing, multimedia applications were, until the mid-90s, uncommon due to the expensive hardware required. With increases in performance and decreases in price, however, multimedia is now commonplace. Nearly all PCs are capable of displaying video, though the resolution available depends on the power of the computer’s video adapter and CPU.

EXAMPLES OF MULTIMEDIA
There are several types of media, including video, audio, and text. A multimedia device allows a person to deal with a variety of these media while eliminating the need to have a separate device for each. There are numerous tasks that may be accomplished on these devices, such as creating, editing, and transferring files. Many of these devices are compatible with computers, which allows them to be easily dealt with in ways that may not otherwise be possible. These are: Graphics, 2. Animation, 3. Audio, 4. Video 5. Analog 6. Flash player 7. QuickTime 8. Multimedia 9. Portfolio Video 10. Elements3D 11. Elements Interactive 12. Flash Audio 13. Elements PDF as a website 14. Audio Handling 15. Video Output, 16. Phonon, 17 Memory Card, 18. A tablet Computer and 19 MP3 Player.

AIOU CODE 1431 SOLVED ASSIGNMENT 2 SPRING 2017 COMPUTER GRAPHICS

I. GRAPHIC:- The term computer graphics includes almost everything on computers that is not text or sound. Today almost every computer can do some graphics, and people have even come to expect to control their computer through icons and pictures rather than just by typing. It refers to any computer device or program that makes a computer capable of displaying and manipulating pictures. The term also refers to the images themselves. For example, laser printers and plotters are graphics devices because they permit the computer to output pictures. A graphics monitor is a display monitor that can display pictures. A graphics board (or graphics card) is a printed circuit board that, • when installed in a computer, permits the computer to display pictures. Many software applications include graphics components. Such programs are said to support graphics. For example, certain word processors support graphics because they let you draw or import pictures. All CAD/CAM systems support graphics. Some database. management systems and spreadsheet programs support graphics because they let you display data in the form of graphs and charts. Such applications are often referred to as business graphics.
1. ANIMATION:-
A simulation of movement created by displaying a series of pictures, or frames. Cartoons on television is one example of animation. Animation on computers is one of the chief ingredients of multimedia presentations. There are many software applications that enable you to create animations that you can display on a computer monitor. Note the difference between animation and video. Whereas video takes continuous motion and breaks it up into discrete frames, animation starts with independent pictures and puts them together to form the illusion of continuous motion.

2. AUDIO:-
When considering multimedia applications audio is very important. Traditionally computers have relied on visual interfaces, and audio facilities were very limited. Now, however, most personal computers will have sound cards and speakers, and the hardware to upgrade those that do not is relatively cheap. Audio can be used to enhance multimedia applications in a number of ways, for example in delivering lectures over the web, music used to add interest and emotion to a presentation, and other non-speech audio used as part of a general interface. Computer audio is far simpler and more approachable then you might think. Computer Audio Demystified was written to help you get a handle in this new and exciting way to experience music in your home. VI.0 media player is one of the best open-source multimedia players out there. Its great portability features and sleek interface make the player very easy-to-use, so even the inexperienced users can master the program relatively fast. The wide supported format range will also meet the needs of almost any user. QuickTime is a media player that supports most common audio and video formats. It also conies with a basic image viewer that supports most popular image formats. It offers a simple GUI with basic buttons to play, seek, and adjust volume. It is a bit slow to open, but other than that it performs well during audio and video playback. It works great with IlD and Full-III) videos

3. VIDEO:-
DVDs, streaming video on the web, and films are engaging instructional tools. Everyone benefits from dynamic visual displays and dialog. Well, not everyone. Viewers who are deaf miss all audio content that is not also presented in a visual form. Those who are blind can access only the visual content that is also presented in spoken form. It is usually not difficult to make video and multimedia products accessible to viewers with sensory impairments, but special considerations should be made at the design phase to ensure complete access to everyone. Including accessibility features when the product is being developed is much easier than providing accommodations to viewers with sensory impairments once they need to access the media. Building in accessibility features for all instructional products is in keeping with principles of universal design. To experience watching a multimedia product without the ability to hear, turn off the volume on your television set or computer during a video presentation. Some programs, such as sporting events, are fairly easy to follow by watching the visual display. Others, such as news programs, make little sense without audio. To make this content accessible to those who are deaf, the program developer could arrange for a sign language interpreter or text captioning to appear on the screen. Captioning involves synchronizing text with audio content of a video presentation. It is more common than sign language because not all individuals who are deaf know sign language, there is no one standard version of sign language, and the intricate motions of sign language may be difficult to display clearly, especially when scientific or other highly specialized language is used. Millions of people worldwide experience enough hearing loss to affect their ability to watch a television program at a standard volume level. Some people are born deaf or hard of hearing, some experience a hearing loss from an accident or illness, and many gradually lose their ability to hear. The elderly are the fastest growing group of individuals who are deaf or hard of hearing. Captions on video products allow these people to fully access educational and recreational programs with family, friends, and fellow students.

AIOU CODE 1431 SOLVED ASSIGNMENT 2 SPRING 2017 COMPUTER ANALOG SYSTEM

4. ANALOG :-
It is multimedia computer in which continuously variable physical quantities, such as electrical potential, fluid pressure, or mechanical motion, are used to represent (analogously) the quantities in the problem to be solved. The analog system is set up according to initial conditions and then allowed to change freely. Answers to the problem are obtained by measuring the variables in the analog model. Analog computers are especially well suited to simulating dynamic systems; such simulations may be conducted in real time or at greatly accelerated rates, allowing experimentation by performing many runs with different variables. They have been widely used in simulating the operation of aircraft, nuclear power plants, and industrial chemical processes. It represents data by measurable quantities, as voltages or, formerly, the rotation of gears, in order to solve a problem, rather than by expressing the data as numbers. An analog provides a better representation of the recorded information? Well, since computers perform digital computations, they can only work with digital media. Therefore, all analog audio or video media must be converted to digital to work on a computer. Once the information is digital, computers can be used to edit the data and create effects that were never possible with analog media. Digital media is non-linear, which means it can be edited or played back starting at any point, which can be a huge timesaver compared to working with tape. Digital information also does not “wear out” after repeated use like tapes or records do, which results in much better longevity for digital media. To summarize, a digital signal is an estimation of analog data. Digital recordings are made with ones and zeros, while analog recordings are made with linear bumps and dips. While digital information is not as exact as analog information, it can be used with other digital devices, such as computers, making editing and reproduction of the information easier and faster. Because digital media is more compatible and does not degrade over time, it has become the common choice for today’s audio and video formats.

AIOU CODE 1431 SOLVED ASSIGNMENT 2 SPRING 2017 MULTIMEDIA KIOSK

Q 5: Write a note (in your own words) on the following:-
• *Multimedia Kiosk
• *High Level Language
• *Complier and Interpreter

Answer:-
1):- MULTIMEDIS KIOSK:-
A multimedia Kiosk is any type of large computer terminal, most often located in a public place, which the general public may use for various purposes. An ATM is a type of multimedia kiosk, for instance; a user can walk up to the terminal, insert a debit card, and withdraw money from an account without needing to interact with a bank teller or other employee. Multimedia kiosks are often found in places such as supermarkets, shopping malls, airports, and convenience stores, among others, and most feature convenient to tich screens. Though an ATM is probably the most common type of multimedia kiosk, there are many others available as well. A photo printing kiosk is very common. These often have different functions; for instance, one may be able to insert the memory card from a digital camera. The photos will then be loaded onto the screen, where the user can individually select which photos he or she wants to print.

AIOU CODE 1431 SOLVED ASSIGNMENT 2 SPRING 2017 HIGH LEVEL LANGUAGE

2):- High Level Language
Very early in the development of computers attempts were made to make programming easier by reducing the amount of knowledge of the internal workings of the computer that was needed to write programs. If programs could be presented in a language that was more familiar to the person solving the problem, then fewer mistakes would be made. High level programming languages allow the specification of a problem solution in terms closer to those used by human beings. These languages were designed to make programming far easier, less error-prone and to remove the programmer from having to know the details of the internal structure of a particular computer. These high-level languages were much closer to human language. One of the first of these languages was Fortran II which was introduced in about 1958. In Fortran II our program above would be written as: C = A + 8
which is obviously much more readable, quicker to write and less error-prone. As with assembly languages the computer does not understand these high-level languages directly and hence they have to be processed by passing them through a program called a compiler which translates them into internal machine language before they can be executed.
Another advantage accrues from the use of high-level languages if the languages are standardized by some international body. Then each manufacturer produces a compiler to compile programs that conform to the standard into their own internal machine language. Then it should be easy to take a program which conforms to the standard and implement it on many different computers merely by re-compiling it on the appropriate computer. This great advantage of portability of programs has been achieved for several high-level languages and it is now possible to move programs from one computer to another without too much difficulty. Unfortunately many compiler writers add new features of their own which means that if a programmer uses these features then their program becomes non-portable. It is well worth becoming familiar with the standard and writing programs which obey it, so that your programs are more likely to be portable.
As with assembly language human time is saved at the expense of the compilation time required to translate the program to internal machine language. The compilation time used in the computer is trivial compared with the human time saved, typically seconds as compared with weeks. Many high level languages have appeared since Fortran II (and many have also disappeared!), among the most widely used have been:

AIOU CODE 1431 SOLVED ASSIGNMENT 2 SPRING 2017 COMPILER AND INTERPRETER

COMPILER AND INTERPRETER
Just understand the concept of the compiler and interpreter
1. We give complete program as input to the compiler. Our program is in the human readable format.
2. Human readable format undergoes many passes and phases of compiler and finally it is converted into the machine readable format.
3. However interpreter takes single line of code as input at a time and execute that line. It will terminate the execution of the code as soon as it finds the error.
4. Memory requirement is less in Case of interpreter because no object code is created in case of interpreter.

COMPILER:-
1:- Compiler Takes Entire program as input
2:- Intermediate Object Code is generated
3:- Conditional Control Statements are Executes faster
4:- Memory Requirement: More (Since Object Code is generated)
5:- Program need not be compiled every time
6:- Errors are displayed after entire program is checked
7 Example:- C Compiler

FIND THE:- AIOU SOLVED ASSIGNMENT 1 CODE 1431 SPRING 2017

INTERPRETER:-
1:- Interpreter Takes Single instruction as input.
2:- No Intermediate Object Code is generated
3:- Conditional Control Statements are Executes slower
4:- Memory Requirement is less
5:- Every time higher level program is converted into lower level program
6:- Errors are displayed for every instruction interpreted (if any)
7:- Example: BASIC
