Hardware interfaces

Hardware interfaces exist in computing systems between

many of the components such as the

variousbuses, storage devices, otherI/O devices, etc. A hardware interface is described by the mechanical,

electrical and logical signals at the interface and the

protocol for sequencing them (sometimes called

signaling).[1]

Hardware interfaces

A standard interface, such as SCSI, decouples the design

and introduction of computing hardware, such

as I/O devices, from the design and introduction of other

components of a computing system, thereby allowing

users and manufacturers great flexibility in the

implementation of computing systems.[1]

Hardware interfaces can beparallel where performance is

important orserial where distance is important.

SCSI: Small Computer System

Interface SCSI is actually an acronym for Small Computer System Interface

and it is pronounced as "skuzzy". It is the second-most popular hard

disk interface used in PCs today. It's a high-speed,

intelligent peripheral I/O bus with a device independent protocol

for transferring data between different types of peripheral devices. The SCSI bus connects all parts of a computer system so that they

can communicate with each other. The bus frees the host processor

from the responsibility of I/O internal tasks. A SCSI bus can be either

internal, external, or cross the boundary from internal to external. The

SCSI protocol is a peer-to-peer relationship: one device does not

have to be subordinated to another device in order to perform I/0

activities. Only two of these devices can communicate on the bus at

any given time.


56/56

Each SCSI bus can connect up to 8 or up to 16 peripherals; one of

those devices will always be the computer or the SCSI card, because

they too are devices on the SCSI. SCSI devices are designated as

either initiators (drivers) or targets (receivers) and the interface to the

host computer is called the host adapter. Every device connected to

the bus will have a different SCSI ID, ranging from 0 to 7. The host

adapter takes up one ID leaving 7 ID's for other hardware. SCSI

hardware typically consists of hard drives, tape drives, CD-ROMs,

printers and scanners
