Exam 7: Input Output

A set of I / O modules is a key element of a computer system.

A multipoint external interface provides a dedicated line between the I / O module and the external device.

The disadvantage of the software poll is that it is time consuming.

The 8237 DMA is known as a _________ DMA controller.

The Thunderbolt protocol _________ layer is responsible for link maintenance including hot-plug detection and data encoding to provide highly efficient data transfer.

________ is when the DMA module must force the processor to suspend operation temporarily.

There are four types of I / O commands that an I / O module may receive when it is addressed by a processor: control,test,write,and _________.

The ________ is a single-chip,general-purpose I / O module designed for use with the Intel 80386 processor.

The most common means of computer / user interaction is a __________.

The rotating interrupt mode allows the processor to inhibit interrupts from certain devices.

The categories for the major functions or requirements for an I / O module are: control and timing,device communication,data buffering,error detection,and _________.

An I / O module must recognize one unique address for each peripheral it controls.

The U.S.national version of the International Reference Alphabet is referred to as __________.

A Thunderbolt compatible peripheral interface is no more complex than that of a simple USB device.

In a _________ interface there are multiple lines connecting the I / O module and the peripheral and multiple bits are transferred simultaneously.

An I / O module that takes on most of the detailed processing burden,presenting a high-level interface to the processor,is usually referred to as an _________.

A ________ connects InfiniBand subnets,or connects an InfiniBand switch to a network such as a local area network,wide area network,or storage area network.

With isolated I / O there is a single address space for memory locations and I / O devices.

The ________ layer is the key to the operation of Thunderbolt and what makes it attractive as a high-speed peripheral I / O technology.

An I / O module that is quite primitive and requires detailed control is usually referred to as an _________.
