第1题：

MIDI enables people to use(11)computers and electronic musical instruments. There are actually three components to MIDI, the communications"(12).", the Hardware Interface and a distribution(13)called "Standard MIDI Files". In the context of the WWW, the most interesting component is the(14)Format. In principle, MIDI files contain sequences of MIDI Protocol messages. However, when MIDI Protocol(15)are stored in MIDI files, the events are also time-stamped for playback in the proper sequence. Music delivered by MIDI files is the most common use of MIDI today.

A．personal

B．electronic

C．multimedia

D．network


正确答案：C

第2题：

以下是有关MIDI设备的叙述： I．所有遵循MIDI标准的数字式电子乐器统称为MIDI设备 II．可将MIDI键盘演奏时产生的MIDI消息通过声卡输入PC中 III．可将多个MIDI设备以菊花链方式串接起来 IV．MIDI设备有三种不同的端口：MIDI in、MIDI out、MIDI thru 上述叙述中，哪些是正确的?

A．仅I、II和III

B．仅I和IV

C．仅II和III和IV

D．全部


正确答案：D
解析：遵循MIDI标准的数字式电子乐器(称为MIDI设备)可以相互连接，也可以通过声卡与计算机进行连接，作为计算机的输入/输出设备。MIDI设备的端口有3种：MIDI in、MIDI out和MIDI thru，它们都是5芯DIN插座，相互之间以菊花链方式连接。

第3题：

●A user interface can be defined as the combination of hardware and software that helps people and computers (72) with each other.

(72) A．intercourse

B．intercommunion

C．communicate

D．intercommunicate


正确答案：C

【解析】用户界面可以定义为软件和硬件的结合，它帮助人与计算机进行交互。

第4题：

MIDI enables people to use（ ）computers and electronic musical instruments.There are actually three components to MIDI,the communications"（ ）",the Hardware interface and a distribution（ ）called"Standard MIDI Files".In the context of the WWW,the most interesting component is the（请作答此空）Format.In principle,MIDI files contain sequences of MIDI Protocol messages:However,when MIDI Protocol（ ）are stored in MIDI files,the events are also time-stamped for playback in the proper sequence.Music delivered by MIDI files is the most common use of MIDI today.

A.Video
B.Faxmail
C.Graphic
D.Audio

答案：D
解析：
MIDI使得人们能够使用多媒体计算机和电子乐器。实际上MIDI有3种元素：通信协议、硬件接口和被称为标准MIDI文件的发布格式。在WWW环境中，最重要的元素是音频格式。在原理上，MIDI文件包含了MIDI协议报文序列。然而当MIDI协议报文被存储在MIDI文件中时，事件都被加上了时间戳，以便于按照适当的顺序回放。由MIDI文件提供的音乐是MIDI当前最通常的应用。

第7题：

Cloud computing is a phrase used to describe a variety of computing concepts that involve a large number of computers （ ）through a real-time communication network such as the Internet．In science，cloud computing is a （ ）for distributed computing over a network，and means the （ ）to run a program or application on many connected computers at the same time．The architecture of a cloud is developed at three layers： infrastructure，platform，and application，The infrastructure layer is built with virtualized compute，storage，and network resources．The platform layer is for general-purpose and repeated usage of the collection of software resources．The application layer is formed with a collection of all needed software modules for SaaS applications．The infrastructure layer serves as the（请作答此空）for building the platform layer of the cloud． In turn，the platform layer is a foundation for implementing the（ ）layer for SaaS applications．

A.network
B.foundation
C.software
D.hardware

答案：B
解析：
云计算是用来描述各种计算概念的短语，包括大量计算机通过网络相互连接以实现分布计算，意思是同时在很多互联的计算机上运行程序或应用的能力。云的架构分为基础设施层、平台层和应用层三层。基础设施层由虚拟计算、存储和网络资源构成。平台层用于一组软件资源重复使用的通用目的。应用层由一组所需的软件模块构成，即软件即服务（SaaS)。基础设施层作为构建平台层的基础。相反，平台层是应用层的基础，为SaaS应用实现应用层。

第10题：

An operating system also has to be able to service peripheral（ ）,such as timers,motors,sensors,communicationdevices,disks,etc.All of those can request the attention of the OS（ ）,i.e.at the time that they want to use the OS,theOS has to make sure it's ready to service the requests.Such a request for attention is called an interrupt.There are twokinds of interrupts:Hardware interrupts and Software interrupts.The result of an inteiTup:is also a triggering of theprocessor,so that it jumps to a（ ）address.Examples of cases where software interrupts appear are perhaps a divide by zero,a memory segmentation fault,etc.So this kind of interrupt is not caused by a hardware event but by a specificmachine language operation code.Many systems have more than one hardware interrupt line,and the hardwaremanufacturer typically assembles all these interrupt lines in an interrupt（请作答此空）.An Interrupt（ ）is a piece of hardware that shields the OS from the electronic details of the interrupt lines,so that interrupts can be queued and none of themgets lost.

A.vector
B.array
C.queue
D.ist

答案：A
