Exam 10: System Architecture

Middleware provides a transparent interface that enables system designers to integrate dissimilar software and hardware.

A main disadvantage of server-based processing is that only one type of terminal can communicate with the mainframe, and the design is tied to a specific hardware platform.

Discuss cloud computing at length, including its advantages and disadvantages. Be sure to include a definition of all relevant terms in your explanation

Most companies resolved the problems of stand-alone computing by joining clients into a(n) ____________________ that allows sharing of data and hardware resources.

In the OSI (Open System Interconnection) model, data proceeds up through the layers on the receiving computer. _________________________

Client/server designs take only one form, regardless of the type of server or the relationship between the server and the clients.

In a(n) ____ design, the remote user's keystrokes are transmitted to the mainframe, which responds by sending screen output back to the user's screen.

A(n) ____________________ spans long distances and can connect LANs that are continents apart.

Every information system involves ____.

A(n) ____ is relatively inexpensive to install and is well-suited to workgroups and users who are not anchored to a specific desk or location.

____ describes how data actually moves from an application on one computer to an application on another networked computer.

____________________ translates the logical design of an information system into a physical structure that includes hardware, software, network support, and processing methods.

One disadvantage of a hierarchical network is that if a business adds additional processing levels, the network becomes more complex and expensive to operate and maintain.

The ____ topology allows the expansion of wireless access over a wide area.

-At the center of the network shown in the accompanying figure is the ____, which manages the network and acts as a communications conduit for all network traffic.

List at least five guidelines for developing an e-commerce site in-house.

MATCHING Identify the letter of the choice that best matches the phrase or definition. -In most companies, workstations that use these have replaced character-based terminals.

File sharing designs are efficient only if ____.

In its wireless configuration, the ____ point is similar to a hub in the LAN star topology, except it provides network services to wireless clients instead of wired clients.

-In a(n) ____________________ client/server design, as illustrated in the accompanying figure, the user interface resides on the client, all data resides on the server, and the application logic can run either on the server, on the client, or be divided between the client and server.
