●At a basic level, cloud computing is simply a means of delivering IT resources as (71).Almost all IT resources can be delivered as a cloud service: applications, compute power, storage capacity, networking,programming tools,even communication services and collaboration (72)。
Cloud computing began as large-scale Internet service providers such as Google,Amazon,and others built out their infrastructure. An architecture emerged: massively scaled, (73) distributed system resources,abstracted as virtual IT services and managed as continuously configured, pooled resources. In this architecture, the data is mostly resident on (74)“somewhere on the Intemet”and the application runs on both the "cloud servers”and the user's browser.
Both clouds and grids are built to scale horizontally very efficiently. Both are built to
withstand failures of (75) elements or nodes. Both are charged on a per-use basis. But while grids typically process batch jobs, with a defined start and end point, cloud services can be continuous. What's more, clouds expand the types ofresources available —— file storage, databases, and Web services —— and extend the applicability to Web and enterprise applications.
(71) A. hardware
B. computers
C. services
D. software
(72) A.computers
B.disks
C.machines
D.tools
(73 ) A. horizontally
B. vertically
C. inclined
D. decreasingly
(74) A. clients
B. middleware
C. servers
D. hard disks
(75) A.entire
B.individual

A transport layer protocol has several responsibilities. One is to create a process-to-process (program-to-program) communication; TCP uses port (71) to accomplish this. Another responsibility of a transport layer protocol is to create a (72) and error-control mechanism at the transport level. TCP uses a sliding (73) protocol to achieve flow control. It uses the acknowledgment packet, time-out, and retransmission to achieve (74) control. The transport layer is also responsible for providing a connection mechanism for the application program. The application program sends (75) of data to the transport layer. It is the responsibility of the transport layer at the sending station to make a connection with the receiver.（71）A．numbersB．connectionsC．diagramsD．resources
