With all the advancements made in technology, motherboards have not stood still. They have become smaller, more versatile, and more convenient. Motherboards have evolved from the basic storage and data interface that they once were to become a complete computer system that can be integrated into a personal computer or a network server. The old SCSI bus cards could be replaced by SATA or serial ATA controllers that would attach directly to the hard drive, eliminating the need for a separate card. File systems, application software, and operating systems could all be accessed through the same hard drive.
Early motherboards used SCSI ports which used parallel cables to transport data storage and bus signals between the CPU and the platters of the hard drive. Motherboards also had serial port interfaces that handled parallel data transfers to other hardware devices. USB and FireWire ports were also available for connecting the motherboard to peripheral devices.
Today’s modern motherboards interface with the USB, FireWire, and parallel port bus that drives modern-day drives such as HD, DVD, and CD players. Some even have their own eSATA ports that connect to external hard drives or other data storage drives. In addition, most have standard audio and video ports that allow connections to a headset, computer mouse, or other input device.
Motherboards interface with the existing SCSI bus hard drives. SCSI stands for Small Computer System Interface. SCSI was designed so that it could support small computer systems without requiring expensive, big, power-hungry machines. Modern hard drives are very small, often less than one inch in size. This smallness made them easy to incorporate into a standard computer system. Modern operating systems also use SCSI to allow the user to open any drive on the computer.
The typical integrated circuit on a computer today is a bipolar microprocessor. The microprocessor performs basic logic operations such as adding, subtracting, and multiplying numbers. These operations are carried out by the central processing unit or CPU. The speed at which the CPU performs these operations determines the speed with which the computer will run. The speed of the CPU is determined by its architecture and is an integral part of the motherboard.
The integrated-circuit board or motherboard contains the various components of the computer system unit. The various components of the mother board include the computer system unit, main memory chip, boot ROM chip, random access memory chip, system board, voltage control circuit board, and external peripherals such as printers, scanners, keyboards, and CD-ROMs. Each component has a specific function that enables it to work properly with the other components. A good example of a component is the power component. The motherboards supply the power to the various components and the power plug usually connects to the Motherboard. The video subsystem contains a processor that controls the video outputs on the computer motherboard.
Motherboards can be built with a variety of different types of hard drive connectors. The most common hard drive connectors are SATA cable, FireWire cable, USB cable, eSATA connector, single cable, double cable, multi-lane cable, DVD-ROM drive, CD-RW drives, and others. Some motherboards also have built-in flash drive capability that can be utilized for the installation of data files. This kind of installation is referred to as NAS installation.
Other types of hard drives that can be attached to a Motherboard are the following: erratic hard disk, solid state drives, memory sticks, flash drives, and others. An important thing to note about a USB flash drive is that it cannot be recognized by Windows. Therefore, you need to install additional software to assist in USB storage. For Windows operating systems, you can use Microsoft External Storage Device Runner which is an application that detects USB flash drives and identifies which one is the right one for you.
