Multimedia is usually recorded and played, displayed or accessed by information content processing devices, such as computerized and electronic devices, but can also be part of a live performance. Multimedia (as an adjective) also describes electronic media devices used to store and experience multimedia content. Multimedia is distinguished from mixed media in fine art; by including audio, for example, it has a broader scope. The term "rich media" is synonymous for interactive multimedia. Hypermedia can be considered one particular multimedia application.

There are many types of application software:

• An application suite consists of multiple applications bundled together. They usually have related functions, features and user interfaces, and may be able to interact with each other, e.g. open each other's files. Business applications often come in suites, e.g. Microsoft Office, OpenOffice.org, and iWork, which bundle together a word processor, a spreadsheet, etc.; but suites exist for other purposes, e.g. graphics or music.

• Enterprise software addresses the needs of organization processes and data flow, often in a large distributed environment. (Examples include Financial, Customer Relationship Management, and Supply Chain Management). Note that Departmental Software is a sub-type of Enterprise Software with a focus on smaller organizations or groups within a large organization. (Examples include Travel Expense Management, and IT Helpdesk)

• Enterprise infrastructure software provides common capabilities needed to support Enterprise Software systems. (Examples include Databases, Email servers, and Network and Security Management)

• Information worker software addresses the needs of individuals to create and manage information, often for individual projects within a department, in contrast to enterprise management. Examples include time management, resource management, documentation tools, analytical, and collaborative. Word processors, spreadsheets, email and blog clients, personal information system, and individual media editors may aid in multiple information worker tasks.

• Content access software is software used primarily to access content without editing, but may include software that allows for content editing. Such software addresses the needs of individuals and groups to consume digital entertainment and published digital content. (Examples include Media Players, Web Browsers, Help browsers, and Games)

• Educational software is related to content access software, but has the content and/or features adapted for use in by educators or students. For example, it may deliver evaluations (tests), track progress through material, or include collaborative capabilities.

• Simulation software are computer software for simulation of physical or abstract systems for either research, training or entertainment purposes.

• Media development software addresses the needs of individuals who generate print and electronic media for others to consume, most often in a commercial or educational setting. This includes Graphic Art software, Desktop Publishing software, Multimedia Development software, HTML editors, Digital Animation editors, Digital Audio and Video composition, and many others.[2]

• Product engineering software is used in developing hardware and software products. This includes computer aided design (CAD), computer aided engineering (CAE), computer language editing and compiling tools, Integrated Development Environments, and Application Programmer Interfaces.

Basic multimedia communication technology tends to cover a range of multimedia devices, such as sound cards and graphic cards that allow users to create visual presentations that output sound and /or images. Multimedia generally means the combination of two or more continuous media. The two media are normally audio and video, sound plus moving pictures. For example the digital camera may be used externally to the PC, and allows the user to record images. When connecting the camera to the computer, using a cord, images will be formatted and printed. Various computers have sound cards stored within them, this allows output of sound from speakers through the use of CD's, and other formats that may have music attached to it. Sound cards allow individuals to listen to music played or stored on their computer.

Whereas Communications technology refers to the transmission of data from one computer to another from one device to another. Computer systems refer to an entire working computer. All computer systems consist of various components they include the case of the computer the power supply and many other components.

The Motherboard in a computer that manages the communication and function of all information. The Processor is another term for (CPU) Control Panel Unit. A microprocessor chip, the CPU is the brain of the computer; it uses mathematical functions to perform calculations.

Random Access Memory

Also referred to as the (RAM) holds the application programs and data in current use, it may also be occupied by software as operating systems and interpreters.

Computer systems also include a Bus, the Hard Drive which has encoding data on the hard drive there has been two approaches firstly being the MFM, and the next being RLL. Other components include Peripherals, Monitor, Keyboard, and various Pointed Devices including Joysticks.

Computer Networks

Computer networks are able to achieve communication between a couple of computers. Networks are split into three parts.

Local Area Network

A Local Area Network is also known as a (LAN) they are privately owned networks within a single building or campus. LANs are distinguished from other kinds of networks by three characteristics (1) their size, (2) their transmission technology, and (3) their topology.

Hub

Bridge

Router

Network Interface Card

The Network Interface Card allows devices to connect to the network. They provide connections for any type of networking media, including wireless media. Internal hardware installed within computer amongst other devices that allow them to communicate on a network.

Metropolitan Area Network

This is constructed of LANs that are interconnected across a city or metropolitan area. An example of a MAN is the cable television network available in many cities. MANs require routers, telephone and ATM switches, and microwave antennas. They produce single points of connection between each LAN.

ATM Switch

A network device which is used by telecommunications companies like the local telephone company to support multiple connections on an ATM network.

Wide Area Network

This is also referred to as a (WAN) Two or more LANs or MANs, which are interconnected using slow-speed connections over telephone lines.

Modem

types of businesses, including mass media research (Wimmer& Dominick, 2003). But we can say that the effects of the Internet are obvious in almost every field of Human Life.

The Internet has had a dramatic affect on the way people communicate, conduct business, and process information, and it has affected mass media and research as well. For instance, the Internet has:

• Created new methods for gathering Mass Media data (Web search).

• Changed the way researchers search for and disseminate information.

• Simplified collaboration and interaction among researchers.

• Provided new material for analysis (Ibid)

In spite of research, Internet offers exciting opportunities and possibilities for users like: -

• Use of broadband Internet access people can easily download movies, songs, games,

informative data about new trends, cooking recipes, etc. From any library or organization

of the world.

• Interaction with the different peoples with the help of chat rooms, e-mails, e-cards, net

SMS, etc. one can easily communicate in less expensive way.

• E-commerce – involves buying and selling goods and services across the Internet, rather

than traditional outlets such as retail stores etc., also called online marketing to reach the

potential buyers across the globe through Internet. (Jones, 2003, P.162)

• Online journalism-offers a level of interactivity-direct communication between news

organizations and audiences made possible by news forums (Ibid P. 356.). Publishing a

high volume daily newspaper is an intricate business requiring the synchronization of

many different activities. Publishing online can both open new avenues in information

dissemination and build a more dynamic relationship with the reader. This provides

European Journal of Social Sciences – Volume 6, Number 4 (2008)

immediacy, multi-paging, multi media, flexible delivery platforms, and facilities like

archiving. (Adams & Clark, 2001, PP.29-32)

• Learning and sharing cultures-Mcluhan believed that Hollywood and the industry of

advertisers and marketing specialists provided the content for collective hallucination.

Many media were deliberately used to manufacture demand by saturating popular culture

with commercial messages. The resulting polluted mental environment was the most

dangerous consequence of many new Media (Jones, 2003, P.305). Likewise the concepts

of westernization, global culture, pop culture and feminism are penetrated in the

developing countries with the help of New Media.

• Net conferencing-as conference is a task-oriented meeting between two or more people.

Likewise net conferencing mediated by network computers, with or without video or its

like interpersonal or small group communication through which multinational companies

work all over the globe and big celebrities transmit their messages to their associate by

sitting in any corner of the world and get connected via the internet. (Adams& Clark,

2001)

• Researching on the Internet locating the exact data according to your needs by net.

any kind of academic or non-academic information from the Internet. Since these tools

search through vast databases, they are more likely to give you too many results than not

enough. (Ibid)

• Web creating / designing – every individual or organization can easily creates its own

web site and get connected with the world and be the member of exciting cyber space

literally wrap yourself in media and not have to see what’s really going on around you

(William Gibson) (http://www.w3c.com).

• Online books/E-Books -one cannot only consult E-newspaper and e-magazines but lots of books are also available online. Online booksellers give you a variety of books, which can be purchased online (http://www.amazon/e-books.com).

• Internet radio and recordings- making the airwaves surfer friendly. As the speed of the net has been increased, it has made it possible for richer media to be transmitted over the

web. No longer limit to text, we can now send audio and video as well. But one of the

more significant advances has been the development of streaming audio (files can be

playing during down loads) (http://realaudio/realoneplayer.internetradio).

• Internet film – micro cinema movement- term coined in 1991 is a community of independent film makers who produce everything from animated shorts to feature length

movies at a fraction of the cost of the major studios. With digital equipment, these films

are now rivaling the quality of multimillion-dollar productions. Web as distribution medium, the micro cinema community is rapidly growing (http://www.automfilms.com).

The aforesaid uses also shows that how Internet is affecting human life and provide new

insights in the field of mass media.

Hub

This is a LAN device that broadcasts the information it receives to all attached devices and segments of the network.

This limits the collision domain, can extend network distances, and can also filter packets on their MAC addresses and ease congestion.

Router

These have two functions firstly to determine the best path to a destination and to share path information the "route" with other routes. A router can also connect networks using different media and architectures, which enable them to determine the best path for a packet to reach another network. They can also filter broadcasts.

The Network Interface Card allows devices to connect to the network. They provide connections for any type of networking media, including wireless media. Internal hardware installed within computer amongst other devices that allow them to communicate on a network.
