Question 1

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

Accepted Answer

In a client-server network, the presentation logic or user interface is handled by the client computer, while the application and data management logic is managed by the server.

Question 2

An application architecture is the way in which the functions of the application layer are performed solely by the clients in the network.

Accepted Answer

An application architecture determines how the functions of the application layer are distributed between clients and servers in a network. It includes the design of the application components, their interactions, and the environment in which they operate. Therefore, it is not solely performed by clients in the network, making option A false.

Question 3

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

Accepted Answer

The distributed computing model uses the "thin" client approach, where most processing and data storage occurs on the server side.

Question 4

Host-based and client-based networks are similar in that the client computer performs most of the work.

Accepted Answer

Host-based networks rely heavily on the resources of the central host computer, while client-based networks distribute the workload among both the client and host computers. Therefore, the statement that client computers perform most of the work in client-based networks is false.

Question 5

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

Accepted Answer

The standard protocol for communication between a Web browser and a Web server is the Hypertext Transfer Protocol (HTTP).

Question 6

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

Accepted Answer

Middleware acts as a bridge between the client and server application software, allowing them to communicate and share data.

Question 7

The World Wide Web was conceived at University of Utah as part of the development of the Internet.

Accepted Answer

The World Wide Web was actually developed by Sir Tim Berners-Lee while working at CERN in Switzerland as a way to share information among scientists around the world. However, the development of the Internet did play a crucial role in the growth and spread of the World Wide Web.

Question 8

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.

Accepted Answer

Only the request line is required for every HTTP request; the request header and request body are optional and depend on the type of request being made.

Question 9

A server farm is a group of computers that are linked together so they act as a one computer.

Accepted Answer

A server farm is designed to work as a single computing entity, even though it is made up of multiple computers. These computers work together to distribute workloads and provide redundancy in case of failure.

Question 10

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.

Accepted Answer

This statement accurately describes the two main functions of middleware.

Question 11

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

Accepted Answer

Scalability refers to the ability of a system or infrastructure to keep up with increasing or decreasing demands by adding or removing resources such as servers, storage, or network devices.

Question 12

The four general functions of any application program are: data storage, data access logic, application logic and presentation logic.

Accepted Answer

This statement is true. The four general functions of any application program are data storage (i.e. storing and organizing data), data access logic (i.e. retrieving and manipulating data), application logic (i.e. performing specific tasks and operations) and presentation logic (i.e. displaying and formatting data on a user interface).

Question 13

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

Accepted Answer

The statement is not entirely accurate. While host-based computing can be a solution for some network applications, it may not be the best solution for all scenarios. Other options such as cloud-based computing or distributed computing may be more appropriate depending on the specific needs and requirements of the application.

Question 14

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.

Accepted Answer

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.

Question 15

The earliest data communications networks were client-server networks.

Accepted Answer

The earliest data communications networks were not based on the client-server model but were simple point-to-point communication systems, such as telegraph and telephone systems, which do not fit the client-server model.

Question 16

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

Accepted Answer

A "thin client" approach places most of the application logic on the server, not the client. The client typically only handles user input and display of information.

Question 17

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.

Accepted Answer

A request header in an HTTP request does not start with a command; it is the request line that starts with a method like GET and ends with the HTTP version. The headers follow the request line and contain additional information.

Question 18

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

Accepted Answer

A Web browser operates at the application layer, not the data link layer, to enable users to access and navigate the Web.

Question 19

Your typical web browsing scenario where a person using a web browser accesses a web page from a server on the Internet is a good example of a client-server application architecture.

Accepted Answer

When a person uses a web browser to access a web page, the browser acts as the client and requests data from the server on the Internet. The server then responds and sends the requested data back to the client, following the client-server architecture model.

Question 20

The Simple Mail Transfer Protocol is the least commonly used e-mail standard.

Accepted Answer

The Simple Mail Transfer Protocol (SMTP) is actually the most commonly used e-mail standard for transmitting and receiving messages between servers. It is responsible for the delivery of around 90% of all emails on the internet.

Quiz 2: Application Layer

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

An application architecture is the way in which the functions of the application layer are performed solely by the clients in the network.

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

Host-based and client-based networks are similar in that the client computer performs most of the work.

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