I/O Interface

I/O or, alternatively known as input/output refers to any operation, device or program that creates linking or communication between a computer system and outer objects. Input means to enter data to the system, and output is the sent data from the system. Basically, data transferred from or to the host and from or to a secondary device is termed as I/O. In doing so, several input and output devices are used. For example, mouse, keyboard, CD/DVD drives, punch card, etc., are input devices that enter the data to the system. Alternatively, display monitor, printers, etc. are the output devices. Alternatively, DVD-R/W acts as both an input and output device accordingly.

In order to accomplish the desired communication, an I/O interface s required. And to do so, the interface should have the required logic that is capable of interpreting the device location engendered by the main processor. HP, Sun Microsystems, Dell, Compaq is some of the renowned brands that provide such I/O boards

Main Logic Board

Generally, logic is the methodical study of the basic principles of legitimate inference and appropriate interpretation. In case of computers, logic is the systematic arrangements of procedures and principles related to mathematical and arithmetic calculations required to perform different operations. Main logic is implemented on the main board of a computer to accumulate all the necessary logical instructions from diverse primary and secondary components.

Main logic boards act as the heart for any computer system. Various complex calculations, measurements, signaling, different analyses are done with the direct interference of main logic. The microprocessor is one kind of logically structured component that performs all the execution accordingly.

Things to Know About Controllers

Generally, a controller is known as the system or device that controls several components in order to achieve maximum performance. Computer controllers are referred as the devices that control any kind of data transfer from the host to other secondary devices like display screens, disk drives, printers, keyboards, etc. For any kind of personal computer, the controller is designed to work with the computer’s extension bus.

Basically, when a new computer system is assembled, it consists of all the indispensable and standard controllers required to enable the peripheral devices as stated above, and many others as well. Usually, the controllers are single chips that control all the devices linked with a personal computer.

In general, there are three types of bus structural design available for personal computers, namely the PCI (Peripheral Component Interconnect), the AT bus, and the SCSI. Numerous brands of controllers are available nowadays with affordable prices such as Compaq, IBM, Adaptec, Mylex, and many others. You should purchase the controllers that support your computer’s bus architecture to get the best performance.
