Oldest type of motherboard, still used in some systems Table Types of motherboards What manuals (most likely in PDF format) are found on the CD ?. For example, Figure shows a server motherboard with three types of slots. The two long .. This guide can be a PDF file stored on the CD or DVD that came . Motherboards come in different sizes, known as form factors. The most common motherboard form factor is ATX. The different types of ATX are.
During the late s and early s, it became economical to move an increasing number of peripheral functions onto the motherboard.
By the late s, many personal computer motherboards included consumer-grade embedded audio, video, storage, and networking functions without the need for any expansion cards at all; higher-end systems for 3D gaming and computer graphics typically retained only the graphics card as a separate component.
Business PCs, workstations, and servers were more likely to need expansion cards, either for more robust functions, or for higher speeds; those systems often had fewer embedded components. Laptop and notebook computers that were developed in the s integrated the most common peripherals.
This even included motherboards with no upgradeable components, a trend that would continue as smaller systems were introduced after the turn of the century like the tablet computer and the netbook.
Memory, processors, network controllers, power source, and storage would be integrated into some systems.
Design[ edit ] The Octek Jaguar V motherboard from Note the large AT keyboard connector at the back right is its only peripheral interface. The motherboard of a Samsung Galaxy SII ; almost all functions of the device are integrated into a very small board A motherboard provides the electrical connections by which the other components of the system communicate.
Unlike a backplane, it also contains the central processing unit and hosts other subsystems and devices. A typical desktop computer has its microprocessor , main memory , and other essential components connected to the motherboard.
Other components such as external storage , controllers for video display and sound , and peripheral devices may be attached to the motherboard as plug-in cards or via cables; in modern microcomputers it is increasingly common to integrate some of these peripherals into the motherboard itself. An important component of a motherboard is the microprocessor's supporting chipset , which provides the supporting interfaces between the CPU and the various buses and external components.
This chipset determines, to an extent, the features and capabilities of the motherboard. Modern motherboards include: Sockets or slots in which one or more microprocessors may be installed. As of [update] , some graphics cards e.
GeForce 8 and Radeon R require more power than the motherboard can provide, and thus dedicated connectors have been introduced to attach them directly to the power supply. Disk drives also connect to the power supply. Additionally, nearly all motherboards include logic and connectors to support commonly used input devices, such as USB for mouse devices and keyboards. Additional peripherals such as disk controllers and serial ports were provided as expansion cards.
This is achieved by transferring data on the up and down tick of clock cycle. It was designed by Rambus and uses a special high-speed data bus called Rambus channel to transfer data between memory and processor. It offers new features and functions that enable higher clock and data rate operations.
DDR2 transfer 64 bits of data twice every clock cycle. This is called dual-ported memory.
On the other hand DRAM is single ported, which means that the memory can be written to and read from, but one at a time and not simultaneously. VRAM is most commonly used on video accelerator because it outperforms the other memory type by being dual ported.
Flash Memory is used to quickly store data from electronic devices such as digital cameras and MP3 players. Embedded Memory is a small, dense format frequently used on electronic devices with small form factors, such as PDAs and cell phones.
While limited in storage capacity when compared with DRAM modules used on personal computers, embedded memory plays a crucial role in many electronic devices due to its small size. In Optical Memory, data is stored on an optical medium i.
While not currently practical for use in computer processing, optical memory is an ideal solution for storing large quantities of data 2 very inexpensively, and more importantly, transporting that data between computer devices.
