Question 1

Individuals and organizations can use the open-source Linux code to create their own distribution of Linux.

Accepted Answer

Yes, individuals and organizations can use the open-source Linux code to create their own distribution of Linux. This is one of the benefits of open-source software.

Question 2

A multicore microprocessor combines two or more independent processors into a single computer so that they can share the workload and boost processing capacity.

Accepted Answer

A multicore microprocessor is designed to have multiple processing units (cores) within a single physical processor, allowing for parallel processing and increased processing power compared to a single-core processor. Each core can execute tasks independently or in collaboration with other cores to handle complex workloads more efficiently.

Question 3

​As the difference among computer manufacturers in the arenas of price and performance narrows,support for green computing is emerging as a new business strategy for these companies to distinguish themselves from the competition.

Accepted Answer

The statement is true as per the given information.

Question 4

An operating system with multiuser capabilities allows two or more users to run programs at the same time on the same computer.

Accepted Answer

An operating system with multiuser capabilities allows multiple users to access and use the resources of a computer at the same time. Each user can run their own set of programs and the operating system manages and coordinates the sharing of resources between the different users. Examples of multiuser operating systems are Unix/Linux and Windows Server.

Question 5

Compared to secondary storage,main memory offers the advantages of non-volatility,greater capacity,and greater economy.

Accepted Answer

Main memory is volatile, meaning it requires a constant flow of electricity to maintain its contents. Secondary storage, such as hard drives or flash drives, are non-volatile and can retain their contents even without power. While main memory may have faster access times, secondary storage typically offers greater capacity and economy (cost per unit of storage).

Question 6

When making hardware decisions,the overriding considerations of a business should be technology cost.

Accepted Answer

While technology cost is an important consideration when making hardware decisions, it should not be the overriding consideration. Other factors such as the technology's compatibility with existing systems, reliability, security, and ease of use should also be taken into account. Additionally, the specific needs and goals of the business should be considered when making hardware decisions.

Question 7

RAM stands for random access memory,a form of memory that holds its contents even if the current is turned off or disrupted.

Accepted Answer

RAM is a volatile form of memory, meaning it loses its contents when the power is turned off or disrupted.

Question 8

Application software is a set of programs designed to coordinate the activities and functions of the hardware and various programs throughout the computer system.

Accepted Answer

Application software is designed to perform specific tasks for users, such as word processing or browsing the internet, not to coordinate hardware and system functions. That role is typically filled by system software, like an operating system.

Question 9

The components responsible for processing-the central processing unit (CPU)and memory-are housed together in the same box or cabinet,called the system unit.

Accepted Answer

The statement is true.

Question 10

The ability to process (organize and manipulate)data is a small aspect of a computer system.

Accepted Answer

Processing data is a fundamental and essential aspect of a computer system, and it is not a small aspect. Other crucial components of a computer system include storage, input/output devices, operating systems, and software applications.

Question 11

Because of the electromechanical processes involved in using primary storage,it is considerably slower than secondary storage.

Accepted Answer

Primary storage, such as RAM, is electronic and faster than secondary storage, which often involves mechanical processes like those in hard drives.

Question 12

Organic light-emitting diode (OLED)monitors use less power than light-emitting diode (LED)monitors.

Accepted Answer

OLED monitors use organic materials to emit light, which allows for more efficient use of energy compared to LED monitors that use a backlight to illuminate the display.

Question 13

To run,applications request services from the operating system through a defined application program interface (API).

Accepted Answer

Applications do request services from the operating system through a defined application program interface (API). This is how applications interact with the operating system and utilize its resources.

Question 14

With the redundant array of independent/inexpensive disks (RAID)approach,data can be split and stored on different physical disk drives using a technique called mirroring to evenly distribute the data.

Accepted Answer

RAID approach uses mirroring for redundancy, but the technique used to evenly distribute the data on different drives is called striping.

Question 15

Disk mirroring is a method of storing data that generates extra bits of data from existing data,allowing the system to create a "reconstruction map" so that if a hard drive fails,it can rebuild lost data.

Accepted Answer

Disk mirroring, also known as RAID 1, involves copying data identically from one disk to another, creating a mirror image, rather than generating extra bits of data for reconstruction.

Question 16

Optical mark recognition (OMR)is a technology from the 1950s still used to speed up the processing of checks.

Accepted Answer

Optical mark recognition (OMR) technology is still used today, but not mainly for processing checks. It is commonly used for survey forms, questionnaires, and multiple-choice exams.

Question 17

Information systems that operate within the workgroup sphere of influence support a firm in its interaction with customers,suppliers,shareholders,competitors,special-interest groups,the financial community,and government agencies.

Accepted Answer

Information systems that operate within the workgroup sphere of influence primarily support a firm's internal operations and communication within the workgroup or department. They are not typically designed to support external interactions with customers, suppliers, shareholders, etc. Instead, systems such as customer relationship management (CRM), supply chain management (SCM), and enterprise resource planning (ERP) are used for those purposes.

Question 18

The clock speed of a central processing unit (CPU)is independent of machine cycle time.

Accepted Answer

The clock speed of a CPU is directly related to the machine cycle time, as it determines how many cycles per second the CPU can execute.

Question 19

The operating system controls how memory is accessed and maximizes available memory and storage.

Accepted Answer

The operating system manages how memory is allocated and used, and it also optimizes storage usage to maximize available space.

Question 20

The overall trend in secondary storage is toward use of indirect access methods and increased volatility.

Accepted Answer

The trend in secondary storage is towards direct access methods and increased stability, with technologies like SSDs providing faster and more reliable storage solutions.
