Question 1

An operating system is a set of programs that controls the computer hardware and acts as an interface with applications.

Accepted Answer

An operating system (OS) is indeed a set of programs that manages the computer hardware and provides services to applications. It is responsible for allocating resources, managing memory, executing programs, and providing a user interface for interacting with the system.

Question 2

Utility programs help to perform maintenance, correct problems, merge and sort sets of data, keep track of computer jobs, and compress data files.

Accepted Answer

Utility programs are designed to perform various tasks related to the maintenance, organization, and optimization of a computer system. Some of the common functions of utility programs include disk cleanup, virus scanning, data compression, file management, backup and recovery, and system optimization.

Question 3

The primary function of application software is to apply the power of the computer to enable people, workgroups, and the entire enterprise to solve problems and perform specific tasks.

Accepted Answer

The statement is true. Application software is designed to provide specific functionality to users, workgroups, and organizations to solve problems or perform tasks. It may include tools for productivity, communication, data management, and more.

Question 4

The need for additional data storage capacity is one of the factors driving the growth in data centers.

Accepted Answer

The need for additional data storage capacity is a significant factor driving the growth in data centers. As businesses and organizations collect, process, and analyze more data, they require more storage capacity to store and manage this information. This demand for data storage is a primary driver of the expansion of data centers.

Question 5

Suppose your friend, who is a small business owner, wants to computerize her business functions such as accounting, payroll, and inventory management. She would need to purchase separate software to meet each functional requirement.

Accepted Answer

Many software solutions offer integrated systems that can handle multiple business functions like accounting, payroll, and inventory management within a single platform.

Question 6

A command-based user interface employs icons and menus that people use to send commands to the computer system.

Accepted Answer

A command-based user interface relies on users typing commands directly into the system rather than using icons and menus.

Question 7

Corporate executives often object to the use of open-source software because it lacks formal technical support, even though information and solutions regarding the software are usually readily available online.

Accepted Answer

Corporate executives often see formal technical support as essential for their software needs and may feel more comfortable paying for it rather than relying on information and solutions available online. Therefore, they may object to the use of open-source software which typically lacks such formal support. However, the open-source community often has active support forums and documentation available online, making solutions and information readily accessible to users.

Question 8

Some smartphones allow you to take notes and to "write" emails or text messages by speaking into the phone . These are examples of speech-recognition technology.

Accepted Answer

Speech-recognition technology allows users to dictate messages and notes using their voice instead of typing. This technology is becoming increasingly common in smartphones and other devices.

Question 9

A software suite is a collection of programs packaged together as a bundle and typically includes a word processor, spreadsheet program, graphics program, and more.

Accepted Answer

This is a correct definition of a software suite.

Question 10

As the difference among computer manufacturers in the areas 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.

Question 11

Operating systems provide a measure of security by allowing users to access to those resources they've been cleared to use as well as other users' resources if those resources are beneficial.

Accepted Answer

Operating systems provide security by restricting access to resources based on user permissions, not by allowing access to other users' resources without proper authorization.

Question 12

Each programming language has a set of rules, called the program code of the language.

Accepted Answer

Each programming language has a set of rules called the syntax of the language, not the program code.

Question 13

You have lots of images on your hard drive totaling 500 million bytes. A 2 Gigabyte storage device will be adequate to store those photos

Accepted Answer

2 Gigabytes is equal to 2,000,000,000 bytes. Since the total size of the images on the hard drive is only 500 million bytes, a 2 Gigabyte storage device will be more than enough to store those photos.

Question 14

If a large organization wants software that will benefit the entire organization-what's known as enterprise application software-the organization must develop it specifically for the business in order to get the functionality required.

Accepted Answer

Enterprise application software can be purchased off-the-shelf from vendors and customized to meet the specific needs of a business, rather than being developed entirely from scratch.

Question 15

In a typical computer configuration, secondary storage has a much larger capacity than the volatile random access memory.

Accepted Answer

This is true in a typical computer configuration where the secondary storage, such as a hard disk drive, has a much larger capacity than the volatile random access memory (RAM), which is used for temporary data storage.

Question 16

The operating system's application programming interface (API) provides software developers with tools they use to build application software without needing to understand the inner workings of the operating system and hardware.

Accepted Answer

This statement is true. The API abstracts away the complexities of the underlying system and provides a simplified interface for software developers to interact with.

Question 17

Solid state storage devices (SSDs) store data in hard disk drives or optical media rather than memory chips.

Accepted Answer

This statement is incorrect. Solid state storage devices (SSDs) store data in memory chips rather than hard disk drives or optical media. SSDs do not have any mechanical or moving parts, which makes them faster and more durable than traditional hard disk drives.

Question 18

Most operating systems support virtual memory which allocates space on the hard disk to supplement the immediate, functional memory capacity of RAM.

Accepted Answer

This is true. Virtual memory is a technique used by operating systems to allow programs to use more memory than they physically have available. It is implemented by allocating space on the hard disk to temporarily store data that can't fit in the physical RAM.

Question 19

Depending on the brand of tablet you purchase, you may be able to enter data by typing on a keyboard, writing on the screen with a stylus, or speaking into the tablet's microphone.

Accepted Answer

Different brands of tablets offer different methods of data input, including typing, stylus input, and voice recognition.

Question 20

A liquid crystal display (LCD) functions by exciting organic compounds with electric current to produce bright and sharp images.

Accepted Answer

LCD functions by manipulating light using liquid crystals and polarizers, not by exciting organic compounds with electric current.
