Attached to the motherboard will be a mass storage device. The traditional disc drive has been experiencing a transition to the solid-state drive (SSD) system, as they have become more dense and lower cost.
The application and use that the computer will be used for will determine the physical layout of the motherboard as well as the technical requirements. Desktop computers are usually configured with a motherboard that accepts plug-in cards for ease of expansion and reconfiguration. This makes it possible to install more video memory, higher quality sound cards, or take advantage of newer and more current standards, as they are made available. For example, wireless network cards can be installed that allows the user to communicate with a wireless network or hub. Motherboards that are designed for laptops usually have less capability for expansion due to the limitation of space considerations. A motherboard in a laptop will have all the associated circuitry required integrated into the design of the board.
Whether the board is to be used in a desktop or a laptop, certain features and circuitry will reside on the motherboard. Each board is designed to accommodate a particular microprocessor and the board will have a socket and the necessary driver circuitry for it. The board will have the appropriate crystals and clock circuits that are needed to drive the processor at the required speed. Random access memory and the electronics it takes to move data between the processor and memory will also reside on the motherboard.
The mass storage device in a computer has traditionally been a disc drive, but recent innovations have seen a move towards SSDs. The technology to make highly dense memory has been able to produce drives that rival the capacity of traditional discs. In addition, they consume far less power and are highly reliable. Traditional discs that relied on rotating magnetic discs were prone to failure, and the power that they consume contributed to reduced battery life that is an important aspect of a laptop computer.
In conclusion, the application that the computer will be used for will determine the style and configuration of the motherboard. It will determine the speed, power consumption, size, and upgrade capabilities of the final system. Many motherboards, especially laptops, come with a set of integrated chipsets that perform a variety of functions such as video, sound, and networking. However, many also provide a bus that accepts plug in cards for upgrading and expansion. The most modern storage units attached to the computer are SSDs, which provide a high-density medium in a smaller and lower power unit than the traditional disc drive.
One of the most important considerations to be made in regards to configuring a computer system is the selection of an appropriate processor. The style and model of the processor will determine the speed of the computer and the memory capability of the computer. In addition, it will dictate a major portion of the power requirements for the system. Because it is a user of a considerable amount of power, operating temperature and power dissipation requirements also are factors to be considered. The processor resides on a motherboard that has a socket, pin outs, and the required support circuitry needed to run the specific model processor.
