Since its invention in the late 1940’s, computers have passed through a long list of variations. Motherboard had always been the most basic component of all computers as there is no other way to bring down all other components of computer in touch with each other. In its early days, computer used to have a huge motherboard as large as the floor of a large room or hall. Since the technology was not so advanced and the technical and technological approach was also not so developed, therefore there had been a trend to using a separate connector (port) for every peripheral device. Even the sound card and the graphic card were also installed on the motherboard as an external component through slots on it.
Later, as technology developed and new research revealed the effectiveness of high level of integration to bring smarter, faster and more compact computer parts, computers reduced in their sizes and gained high efficiency and speed. Initially, the processor was also installed on the motherboard as an external component but now most of the computer manufacturers emphasize on building it as an on-board component due to its additional benefits in terms of speed and reliability. The invention of USB port played a great part in reducing the size of motherboard because this port is designed to connect almost every peripheral device for which a separate port was required in the past. Latest motherboards have now high bus speed, support for a greater RAM, built in graphic card and sound card (http://www.computervalley.ca/information-technology/multimedia-devices/sound-cards) and on board processor.
RAM which is one of the most vital parts of all computers has also passed through different variation. SDRAM had been an old technology which was slow and less reliable but now DDR1, DDR2 and DDR3 are the latest innovations in this regard aimed to provide high performance by the processors. Older versions of RAM were able to perform at only a few megabytes but now the modern versions of RAM can work even at 8 gigabytes which is really a tremendous speed.
Graphic card is meant to provide the visual display to the video display unit. Initially when the computers worked with command based interfaces, there was no need of a high capacity graphic card but now since it’s an age where everything is presented graphically whether its preparing documents, presentations, models, maps, animations, and all desktop and web applications now involve use of high resolution graphics for which a modern graphic card can provide up to 1 GB support because the modern applications like social media websites, company softawers, animations, media presentations, and other applications need high resolution graphics.
Sound card is also an essential component. There may not be any application that does not involve sounds and for that purpose, a sound card is a pre-requisite. Initially the sound card was also installed on the motherboard (http://www.computervalley.ca/information-technology/electronic-components/motherboards) as an external component on either an ISA slot or a PCI slot but later the emphasized was laid on having a built-in sound card. Another advancement in this regard is that most of the motherboards support a sharing of RAM for the graphic card as well as the sound card to bring the best for the computer users.
