Exam 7: Input Output

Bus arbitration makes use of vectored interrupts.

We can broadly classify external devices into three categories: human readable,communication,and __________.

The ________ command is used to activate a peripheral and tell it what to do.

The _________ contains logic for performing a communication function between the peripheral and the bus.

________ is a digital display interface standard now widely adopted for computer monitors,laptop displays,and other graphics and video interfaces.

The I / O function includes a _________ requirement to coordinate the flow of traffic between internal resources and external devices.

A disadvantage of memory-mapped I / O is that valuable memory address space is used up.

With a daisy chain the processor just picks the interrupt line with the highest priority.

When large volumes of data are to be moved,a more efficient technique is direct memory access (DMA).

The most recent,and fastest,peripheral connection technology to become available for general-purpose use is __________,developed by Intel with collaboration from Apple.

A ________ machine is an instance of an operating system along with one or more applications running in an isolated memory partition within the computer,enabling different operating systems to run in the same computer at the same time,as well as preventing applications from interfering with each other.

I / O channels are commonly seen on microcomputers,whereas I / O controllers are used on mainframes.

The ________ contains I / O protocols that are mapped on to the transport layer.

An I / O channel has the ability to execute I / O instructions,which gives it complete control over I / O operations.

The _________ command causes the I / O module to take an item of data from the data bus and subsequently transmit that data item to the peripheral.

In a ________ interface there is only one line used to transmit data and bits must be transmitted one at a time.

________ enables servers,remote storage,and other network devices to be attached in a central fabric of switches and links,connecting up to 64,000 servers,storage systems,and networking devices.

A ________ controls multiple high-speed devices and,at any one time,is dedicated to the transfer of data with one of those devices.

A ________ is used to connect storage systems,routers,and other peripheral devices to an InfiniBand switch.

It is the responsibility of the processor to periodically check the status of the I / O module until it finds that the operation is complete.
