A plug-in board or circuitry on the motherboard acting as the interface between a computer system bus and the drive. Typically used with embedded controller drives, such as SCSI and IDE.
The controller that routes data to and/ or from the CPU.
An adapter that provides connectivity with an expansion bus. A host adapter is different from a "controller" as it simply acts as a go-between, the controller actually resides on the device. An IDE "controller" is actually a host adapter.
A plug-in board or circuitry on the motherboard that acts as the interface between the system bus and a peripheral device. IDE and SCSI are examples of peripheral interfaces that call their controllers host adapters.
The circuit board that controls a SCSI bus supporting as many as seven or fifteen separate devices. The host adapter controls communication between the SCSI bus and the PC.
A plug-in board that acts as the interface between a computer system bus and the disk drive.
Circuitry that translates between a processor¹s internal bus and a different bus, such as SCSI
This term is synonymous with SCSI adapter. It refers to an add-in board, such as a PCI SCSI card, that allows PCs to communicate with SCSI devices.
A printed circuit board that installs in a standard microcomputer and provides a SCSI bus connection so that SCSI devices can be connected to the microcomputer.
A host adapter implements communication between the computer's bus and the controller for a device. (Hard-disk drive controller subsystems include integrated host adapter circuitry.) To add a SCSI expansion bus to your system, you must install or connect the appropriate host adapter.
A bus-based (PCI, EISA, ISA) hardware device, such as an add-in card or ASIC, that converts the timing and protocol of a host's memory bus and an I/O bus.
In computer hardware, a host adapter or host bus adapter (HBA) connects a host system (the computer) to other network and storage devices. The terms are primarily used to refer to devices for connecting Fibre Channel, eSATA, and SCSI devices (see SCSI host adapter), but devices for connecting to ESCON, Ethernet, and other systems may also be called host adapters. Recently, the advent of i SCSI has brought about Ethernet HBAs, some including TCP Offload Engines.
