I-O DATA offers a wide range of advanced network equipment including wireless LAN devices, which are very useful for comfortable PC life, and gigabit Ethernet devices, which will generate ever growing demand by the developing of infrastructure. We help you build an advanced network environment whether at home or in the office. I-O DATA provides simple solutions for storing and managing of crucial data through innovative storage products, which are compatible with the latest. The I/O subsystem of a computer provides an efficient mode of communication between the central system and the outside environment. It handles all the input-output operations of the computer system. The ETH32 is a general purpose I/O device which communicates using TCP/IP over an ethernet network. This device is ideally suited for remote data acquisition or device control; all that is needed is a connection to an ethernet network. The ETH32 supports up to five simultaneous TCP/IP connections, allowing multiple computers to communicate with the ETH32 device at one time.

Short for input/output (pronounced “eye-oh”). The term I/O is used to describe any program, operation or device that transfers data to or from a computer and to or from a peripheral device. Every transfer is an output from one device and an input into another. Input/output virtualization is a methodology to simplify management, lower costs and improve performance of servers in enterprise environments. I/O virtualization environments are created by abstracting the upper layer protocols from the physical connections. The technology enables one physical adapter card to appear as multiple virtual network interface cards and virtual host bus adapters. Virtual NICs and HBAs function as conventional NICs and HBAs, and are designed to be compatible with exist.
