The primary function of the BUS is
Explanation: The BUS is used to allow the passage of commands and data between cpu and devices.
The classification of BUSes into synchronous and asynchronous is based on
Explanation: The BUS are classified into different types for convenience of use and depending on the device.
The device which starts data transfer is called
Explanation: The device which starts the data transfer is called as initiator.
The device which interacts with the initiator is
Explanation: The device which recieves the commands from the initiator for data transfer.
In synchronous BUS, the devices get the timing signals from
Explanation: The devices recieve their timing signals from the clock line of the BUS.
The delays caused in the switching of the timing signals is due to
Explanation: The time taken for the signal to reach the BUS from the device or the circuit accounts for this delay.
The time for which the data is to be on the BUS is affected by
Explanation: The time for which the data is held is larger than the time taken for propogation delay and setup time.
The Master strobes the slave at the end of each clock cycle in Synchronous BUS.
Which is fed into the BUS first by the initiator..??
_____________ signal is used as an acknowledgement signal by the slave in Multiple cycle transfers.
Explanation: The slave once it recieves the commands and address from the master strobes the ready line indicating to the master that the commands are recieved.
The master indicates that the address is loaded onto the BUS,by activating _____ signal.
Explanation: The signal activated by the master in the asynchronous mode of transmission is used to intimate the slave the required data is on the BUS.
The devices with variable speeds are usually connected using asynchronous BUS.
Explanation: The devices with variable speeds are connected using asynchronous BUS, as the devices share a master-slave relationship.
The MSYN signal is initiated
Explanation: This signal is activated by the master to tell the slave that the required commands are on the BUS.
In IBM’s S360/370 systems _____ lines are used to select the I/O devices.
Explanation: The signal is used to scan and connect to input or output devices.
The meter in and out lines are used for
Explanation: The line is used to monitor the devices usage for a process.
MRDC stands for _______
Explanation: The command is used to initiate a read from memory operation.
The BUS that allows I/O,memory and Processor to coexist is _______
The transmission on the asynchronous BUS is also called as _____
Explanation: The asynchronous transmission is termed as Hand-Shake transfer because the master intimates the slave after each step of the transfer.
Asynchronous mode of transmission is suitable for systems with multiple peripheral devices.
Explanation: This mode of transmission is suitable for multiple device situation as it supports variable speed transfer.
The asynhronous BUS mode of transmission allows for a faster mode of data transfer.
