The key features of the SCSI BUS is
Explanation: The SCSI BUS can overlap various data transfer requests by the devices.
In a data transfer operatioon involving SCSI BUS, the control is with ______
Explanation: The initiator involves in arbitration process and after winning the BUS it’ll handover the control to the target controller.
In SCSI transfers the processor is not aware of the data being transfered.
Explanation: The processor or the controller is unaware of the data being transfered.
The DB(P) line means,
The BSY signal signifies
Explanation: This signal is generally initiated when the BUS is currently occupied in an operation.
The SEL signal signifies
Explanation: This signal is usually asserted during the selection or reselection process.
________ signal is asserted when the initiator wishes to send a message to the target.
Explanation: The ATN signal is short for attention, which is used to initimate the target that the initiator sent a message to it.
The MSG signal is used
_____ is used to reset all the device controls to their startup state.
The SCSI BUS uses ______ arbitration.
Explanation: The SCSI uses distributed arbitration to select the device to give the BUS control.
SCSI stands for ________
Explanation: The SCSI BUS is one of the expansion BUSes used in a system.
ANSI stands for _________
Explanation: This a standard for designing BUSes and other system components.
A narrow SCSI BUS has _____ data lines.
Explanation: The SCSI BUS which is narrow is capable of transfering 8 bits of data at a time.
Single ended transmission means
Explanation: These type of signals are a common feature of the SCSI BUS.
HVD stands for _________
Explanation: This is a type of signaling which uses 5v of current.
For better transfer rates on the SCSI BUS the length of the cable is limited to ______
Explanation: To increase the transmission rate in SCSI in SE mode of transfer the wire length is restricted to 1.6m.
The maximum number of devices that can be connected to SCSI BUS is ______
THe SCSI BUS is connected to the processor through _____
Explanation: This is used to co-ordinate and monitor the data transfer over the BUS.
The mode of data transfer used by the controller is _____
The data is stored on the disk in the form of blocks called _____
Explanation: The data is stored on the disk in the form of a collection of blocks called as sectors.
