What is multimedia?
Multimedia merujuk kepada kandungan yang menggunakan yang menggunakan gabungan yang berbeza. Multimedia merupakan maklumat komputer yang boleh diwakili melalui audio, video dan animasi serta media tradisional iaitu sebagai contoh teks, lukisan grafik, imej atau bentuk kandungan interaktif dan sebagainya.
Multimedia terbahagi kepada lima kategori iaitu:
Text
It may be an easy content type to forget when considering multimedia systems, but text content is by far the most common media type in computing applications. Most multimedia systems use a combination of text and other media to deliver functionality. Text in multimedia systems can express specific information, or it can act as reinforcement for information contained in other media items. This is a common practice in applications with accessibility requirements. For example, when Web pages include image elements, they can also include a short amount of text for the user's browser to include as an alternative, in case the digital image item is not available.
Image
Digital image files appear in many multimedia applications. Digital photographs can display application content or can alternatively form part of a user interface. Interactive elements, such as buttons, often use custom images created by the designers and developers involved in an application. Digital image files use a variety of formats and file extensions. Among the most common are JPEGs and PNGs. Both of these often appear on websites, as the formats allow developers to minimize on file size while maximizing on picture quality. Graphic design software programs such as Photoshop and Paint.NET allow developers to create complex visual effects with digital images.
Audio
Audio files and streams play a major role in some multimedia systems. Audio files appear as part of application content and also to aid interaction. When they appear within Web applications and sites, audio files sometimes need to be deployed using plug-in media players. Audio formats include MP3, WMA, Wave, MIDI and RealAudio. When developers include audio within a website, they will generally use a compressed format to minimize on download times. Web services can also stream audio, so that users can begin playback before the entire file is downloaded.
Video
Digital video appears in many multimedia applications, particularly on the Web. As with audio, websites can stream digital video to increase the speed and availability of playback. Common digital video formats include Flash, MPEG, AVI, WMV and QuickTime. Most digital video requires use of browser plug-ins to play within Web pages, but in many cases the user's browser will already have the required resources installed.
Animation
Animated components are common within both Web and desktop multimedia applications. Animations can also include interactive effects, allowing users to engage with the animation action using their mouse and keyboard. The most common tool for creating animations on the Web is Adobe Flash, which also facilitates desktop applications. Using Flash, developers can author FLV files, exporting them as SWF movies for deployment to users. Flash also uses ActionScript code to achieve animated and interactive effects.

Pembinaan Negara dan Bangsa yang Merdeka - Sistem Ahli
Pengertian Sistem Ahli.
Sistem ahli merupakan satu sistem yang melatih penduduk tempatan untuk mengetahui pentadbiran Tanah Melayu. Sistem ini dilaksanakan pada bulan Januari 1951 hingga Jun 1955. Idea penubuhan Sistem Ahli telah dicetuskan oleh Dato' Onn Jaafar setelah berunding dengan Sir Henry Gurney di Kuala Lumpur.
Dato' Onn Jaafar
Sir Henry Gurney juga mencadangkan agar model negara Kenya dan Rhodesia Utara dilaksanakan di Tanah Melayu. Cadangan ini selaras dengan hasrat British untuk menjalankan dasar Dekolonisasi. Sistem ahli telah dibincangkan dan dipersetujui dalam Mesyuarat Majlis Raja-raja Melayu pada bulan Februari 1950. Sir Henry Gurney telah menjemput Dato'Onn Jaafar (Yang Dipertua Umno) Dato Hamzah Abdullah (Menteri Besar Selangor), Raja Uda dan Dato' Nik Ahmed Kamil yang mewakili Umno dan juga orang melayu, Dato' E.E.C. Thuraisingam mewakili kaum India serta Encik Yong Shook Lin dan Dr. Lee Tiang Keng yang mewakili masyarakat Cina. Mereka telah bersetuju dengan pendekatan Sistem Ahli.
