Question 1

Software that manages the resources of the computer is called

Accepted Answer

Operating system software is responsible for managing the computer's resources, including memory, CPU, and input/output devices. Examples of operating systems include Windows, macOS, and Linux. Application software, on the other hand, is designed to perform specific tasks or functions, such as word processing or photo editing. Data management software is used to organize and manipulate large amounts of data, while network software is used to manage communication between computers in a network.

Question 2

Specifications that establish the compatibility of products and the ability to communicate in a network are called

Accepted Answer

The answer of Specifications that establish the compatibility of products...

Question 3

A SAN is a ________ network.

Accepted Answer

SAN stands for Storage Area Network, which is a specialized network designed to provide access to consolidated, block-level data storage. It is used to enhance storage devices, such as disk arrays, tape libraries, and optical jukeboxes, that are common of direct-attached storage (DAS). Therefore, SAN is a storage area network.

Question 4

In a multi-tiered network

Accepted Answer

In a multi-tiered network, the work is balanced over several levels of servers. This means that the processing is split between the different tiers of servers, rather than being centralized or handled by remote clients. This helps to improve performance, scalability, and reliability of the network.

Question 5

________ unleash powerful economies of scale and result in declines in manufactured computer products.

Accepted Answer

Technology standards help in creating uniformity and compatibility, which leads to mass production and reduced costs, thus unleashing powerful economies of scale.

Question 6

Which of the following is not an IT infrastructure service component?

Accepted Answer

Operating system software is not considered an IT infrastructure service component; it is a part of the software layer that runs on the hardware, whereas the other options are services related to managing and supporting the infrastructure.

Question 7

The network standard for connecting desktop computers into local area networks that enabled the widespread adoption of client/server computing and local area networks and further stimulated the adoption of personal computers is

Accepted Answer

Ethernet is the network standard for connecting desktop computers into local area networks. It enabled the widespread adoption of client/server computing and local area networks, and further stimulated the adoption of personal computers. TCP/IP is a protocol used for internet communication, COBOL is a programming language, and ASCII is a character encoding scheme.

Question 8

All of the following are current hardware platform trends except

Accepted Answer

While green computing, virtualization, and cloud computing are current hardware platform trends, Unix is an existing operating system and is not considered a trend.

Question 9

Which type of infrastructure services provides voice and video connectivity to employees, customers, and suppliers?

Accepted Answer

Telecommunications services provide voice and video connectivity to employees, customers, and suppliers.

Question 10

Today's nanotechnology-produced computer transistors are roughly equivalent in size to

Accepted Answer

Today's nanotechnology-produced computer transistors are roughly equivalent in size to a virus, which is on the nanometer scale.

Question 11

Which of the following factors provides an understanding of why computing resources today are ever more available than in previous decades?

Accepted Answer

All of the factors listed contribute to the availability of computing resources today.

A) Network economics refers to the idea that the value of a network increases as more people use it, which has led to the proliferation of online platforms and increased access to computing resources.

B) The law of mass digital storage predicts that the amount of data that can be stored on a given amount of physical space will double approximately every two years, while Moore's law states that computing power will double approximately every 18 to 24 months. These trends have allowed for the development of more powerful and efficient computing technologies.

C) Declining communications costs, universal standards, and the Internet have all contributed to the ease of accessing and sharing computing resources across a variety of platforms, making it easier to collaborate and share information.

Question 12

Which of the following is not an example of the emerging mobile computing platforms?

Accepted Answer

CRM (customer relationship management) is not a mobile computing platform. It is a software that helps manage customer interactions and data related to customers. The other options (tablets, the Kindle, and cell phones) are all examples of mobile computing platforms.

Question 13

A client computer networked to a server computer, with processing split between the two types of machines, is called a(n)

Accepted Answer

In a two-tiered client/server architecture, the client and server each handle part of the processing, with the client handling the user interface and the server managing database functions.

Question 14

The multitasking, multi-user, operating system developed by Bell Laboratories that operates on a wide variety of computing platforms is

Accepted Answer

The description matches that of Unix, which was developed by Bell Laboratories and is known for being a multitasking, multi-user operating system that can run on various computing platforms. Linux is similar to Unix but was not developed by Bell Laboratories. OS X is a specific operating system developed by Apple for their devices. COBOL is a programming language and not an operating system.

Question 15

The introduction of the minicomputer

Accepted Answer

The introduction of the minicomputer allowed for computers to be customized to the specific needs of different departments or business units, enabled decentralized computing, and offered new, powerful machines at lower prices than mainframes. Therefore, all of the above choices are correct.

Question 16

As referred to in the text, legacy systems are

Accepted Answer

Legacy systems are traditional mainframe-based business information systems.

Question 17

Legacy systems are still used because they

Accepted Answer

The answer of Legacy systems are still used because they
...

Question 18

Which of the following is a leading networking hardware provider?

Accepted Answer

Cisco is a leading provider of networking hardware, including routers, switches, and firewalls. Dell, Seagate, and IBM may offer some networking hardware, but they are not primarily known for it.

Question 19

Place the following eras of IT infrastructure evolution in order, from earliest to most recent: 1. Cloud Computing Era; 2. Client/Server; 3. Enterprise Era; 4. Personal Computer; and 5. Mainframe and Minicomputer.

Accepted Answer

The correct order is: Personal Computer, Mainframe and Minicomputer, Client/Server, Enterprise Era, Cloud Computing Era.

Question 20

Interpretations of Moore's law assert that

Accepted Answer

Moore's Law refers to the observation that the number of transistors on a microchip doubles approximately every two years, which leads to an increase in computing power. While it is not an exact law, it has held true for several decades and is often used as a benchmark for technological progress in the computer industry.
