Question 2

Which of the following statements is true about a public cloud?

Accepted Answer

A public cloud is a service offered by third-party providers for use by any interested party on a pay-per-use or subscription basis. Option A and E are incorrect, as customizability and control over data and applications are typically lower in a public cloud environment, compared to a private or hybrid cloud. Option C is incorrect, as a public cloud is external to the organization, and option D is partially correct, as an organization still needs to manage their use of the cloud infrastructure, but the provider is responsible for the underlying infrastructure maintenance.

Question 3

________ is used to transmit voice and video communication over the Internet.

Accepted Answer

IP convergence is the process of combining voice, video, and data communication onto the same network infrastructure, allowing for the transmission of voice and video communication over the Internet.

Question 4

Networking hardware and software facilitate the interconnection of different computers,enabling collaboration within organizations,across organizations,and literally around the world.

Accepted Answer

Networking hardware and software allow for communication and sharing of resources between different computers, allowing for collaboration within an organization and between organizations across the globe.

Question 5

With respect to the recent trends in IS hardware infrastructure management,________ is moving processing and data storage away from a centralized location to the "corners" of a network.

Accepted Answer

Edge computing involves moving processing and data storage away from a centralized location to the "corners" of a network, such as on local devices or on the edge of a cloud network. Green computing refers to environmentally conscious computing practices, grid computing involves the coordination of multiple resources for distributed computing, trusted computing focuses on secure and trustworthy computing environments, and distributed computing involves the use of multiple computing devices to work together on a task.

Question 6

________ is used to solve large-scale computing problems.

Accepted Answer

Grid computing is a type of distributed computing that involves connecting multiple computers or servers to work together on a large-scale computing problem, often involving complex calculations or data analysis. This allows for faster processing and greater computing power than would be possible with a single computer, making it ideal for tackling large-scale problems such as those encountered in scientific research or financial modeling. Trusted computing, edge computing, and IP convergence are all related to different aspects of computing infrastructure and security, but are not specifically used for solving large-scale computing problems.

Question 7

The application software used for various business processes can directly interact with these various types of computer hardware.

Accepted Answer

The answer of The application software used for various business...

Question 8

Workstations are optimized for access by many concurrent users and therefore have more advanced microprocessors,more memory,a larger cache,and more disk storage than single-user computers.

Accepted Answer

Workstations are optimized for high performance and specialized tasks rather than for supporting many concurrent users. Servers, not workstations, are typically designed to handle multiple concurrent users with advanced processors, more memory, larger cache, and more disk storage.

Question 9

Transmission media refers to the physical pathway used to carry network information.

Accepted Answer

Transmission media refers to the physical pathway used to carry network information.

Question 10

ImmuneEarth,a research and development company,has a motto to "eradicate all diseases." It has numerous departments that research the cure of various diseases.One of its largest departments includes the AIDS department where more than 500 scientists are researching the cure for AIDS.ImmuneEarth has numerous computers that have been grouped into a cohesive system for this purpose.Recently,one of its computers was updated because it had low performance which had slowed the entire system.Which of the following is ImmuneEarth using to research the cure for AIDS?

Accepted Answer

ImmuneEarth is using grid computing, which is a type of distributed computing system that enables multiple computers to work together as a single cohesive resource. This allows for the parallel processing of large amounts of data and can speed up research in fields such as medical research.

Question 11

The name "Internet" is derived from the concept of wireless networking.

Accepted Answer

The name "Internet" is actually derived from the words "interconnected networks". It refers to the connection of various computer networks around the world, rather than wireless networking specifically.

Question 12

Application software helps to automate business processes,and enables processes that would otherwise not even be possible.

Accepted Answer

Application software is designed to automate routine processes and tasks in order to increase efficiency and productivity. It allows users to perform tasks that may not be possible manually, such as sorting and analyzing large amounts of data, sending automated email alerts, and generating reports.

Question 13

________,the use of the Internet protocol (IP)for transporting voice,video,fax,and data traffic,has allowed enterprises to make use of new forms of communication and collaboration,as well as traditional forms of communication,at much lower costs.

Accepted Answer

The term used to describe the use of the Internet protocol for transporting different types of communication traffic is IP convergence. This allows for a more efficient and cost-effective use of communication technologies within enterprises.

Question 14

The easiest way to understand computer networking is through the human communication model.

Accepted Answer

The human communication model involves the process of sending and receiving messages through a medium, which can be applied to computer networking.

Question 15

The fundamental information units of computers are called relays.

Accepted Answer

The fundamental information units of computers are called bits. Relays were used in early computing devices but have since been replaced by electronic components.

Question 16

Which of the following statements is true about the infrastructure as a service model?

Accepted Answer

In the infrastructure as a service (IaaS) model, the customer has to manage the licenses for the operating systems being used. This is because the customer is responsible for provisioning, configuring, and managing the virtual machines and the operating systems that run on them.

Question 17

A supercomputer is primarily used as the main,central computing system for major corporations.

Accepted Answer

While supercomputers may be used by some major corporations, they are primarily used for scientific research, weather forecasting, simulations, and other complex computational tasks that require high processing power.

Question 18

Which of the following differentiates grid computing from cloud computing?

Accepted Answer

The main differentiation between grid computing and cloud computing is that grid computing is applied to a single large problem, while cloud computing involves the provision of dynamically scalable and often virtualized resources over the internet for various purposes. The other options do not accurately differentiate between the two.

Question 19

________ is used to increase Web application performance.

Accepted Answer

Edge computing involves processing data closer to the source of the data, rather than relying solely on a centralized server. This can greatly increase the performance of Web applications, as data can be processed more quickly and with less latency.

Question 20

Information systems infrastructure consists of hardware,system software,storage,networking,and data centers.

Accepted Answer

Information systems infrastructure includes hardware, system software, storage, networking, and data centers.
