The earliest data communications networks were client-server networks.

Answer... Hide Answer: False

Difficulty: Easy

Reference: Host-Based Architectures

As the demand for more and more network applications grow; host-based computing becomes the best solution.

One major drawback to a client-server network lies in the fact that client-server networks enable software and hardware from different vendors to be used together.

Answer... Hide Answer: False

Difficulty: Moderate

Reference: Client-Server Architectures

In a client-server network, the presentation logic is the responsibility of the client computer.

Answer... Hide Answer: True

Difficulty: Easy

Reference: Client-Server Architectures

The two functions of middleware are to: 1) provide a standard way of communicating that can translate between software from different vendors, and 2) manage the message transfer between clients and servers so that clients do not need to ‘know’ which server contains the application’s data.

Answer... Hide Answer: True

Difficulty: Moderate

Reference: Client-Server Architectures

Middleware is the software that sits between the application software on the client and the application software on the server.

Answer... Hide Answer: True

Difficulty: Easy

Reference: Client-Server Architectures

In the three-tier architecture, the software on the client computer is responsible for the presentation logic, an application server is responsible for the application logic and a separate database server is responsible for the data access logic and data storage.

Answer... Hide Answer: True

Difficulty: Moderate

Reference: Two-Tier, Three Tier, and n-Tier Architectures

A “thin client” approach places most of the application logic on the client.

Answer... Hide Answer: False

Difficulty: Easy

Reference: Thin Clients versus Thick Clients

The application architecture called the distributed computing model uses the “thick” client approach.

Answer... Hide Answer: False

Difficulty: Moderate

Reference: Thin Clients versus Thick Clients

Scalability refers to the ability to increase or decrease the capacity of the computing infrastructure in response to changing capacity needs.

Answer... Hide Answer: True

Difficulty: Easy

Reference: Scalability

To use the Web, each client computer requires a data link layer software package called a Web browser.

Answer... Hide Answer: False

Difficulty: Easy

Reference: How the Web Works

The standard protocol for communication between a Web browser and a Web server is the web protocol.

Answer... Hide Answer: False

Difficulty: Moderate

Reference: How the Web Works

A request header for an HTTP request starts with a command, such as GET, and ends with the HTTP version number that the browser understands.

Answer... Hide Answer: False

Difficulty: Easy

Reference: Inside an HTTP Request

All three parts (request line, request header, request body) of an HTTP request from a web browser to a web server are required when a request is made.

Using the POP standard for client to server e-mail communication, the e-mail messages remain on the server computer.

Answer... Hide Answer: False

Difficulty: Easy

Reference: Two-Tier E-mail Architecture

Web-based e-mail like Hotmail is an example of three-tier client-server architecture that provides access to e-mail messages.

Answer... Hide Answer: True

Difficulty: Moderate
