Question 1

Cloud computing is a form of hardware/software leasing in which organizations obtain server resources from vendors that specialize in server processing.

Accepted Answer

Cloud computing is a form of leasing hardware and software resources from specialized vendors who provide server processing services. This helps organizations to avoid the need to invest in and manage their own server infrastructure.

Question 2

The most frequently used data and instructions are placed in cache memory.

Accepted Answer

Cache memory is a high-speed memory that stores frequently used data and instructions for faster access by the CPU. When the CPU needs to access data or instructions, it first checks the cache memory to see if the required information is available there. If it is not available, the CPU retrieves it from the main memory. Therefore, the most frequently used data and instructions are placed in cache memory to improve the overall performance of the system.

Question 3

Ubuntu, a Windows-like desktop operating system, is an open source program.

Accepted Answer

Ubuntu is an open source desktop operating system similar to Windows.

Question 4

Magnetic disk is the most common form of storage hardware.

Accepted Answer

Magnetic disk is the most common form of storage hardware. It is used in hard disk drives, which are found in most personal computers and servers.

Question 5

Thick-client applications are preferred to thin-client applications because they require only a browser.

Accepted Answer

The statement is false. Thick-client applications are different from thin-client applications, as they require more than just a browser to work. Thick-client applications run on a user's computer or device and require local installation, while thin-client applications run on a remote server and are accessed via a web browser or app.

Question 6

Vertical-market application software provides capabilities that can be applied across all organizations and industries.

Accepted Answer

Vertical-market application software is designed for specific industries or organizations and cannot be applied across all industries or organizations.

Question 7

Servers need a great deal of RAM and storage space.

Accepted Answer

Servers need a great deal of RAM and storage space to efficiently store and process data, handle multiple requests, and run various applications and programs. Without sufficient RAM and storage space, server performance and reliability can be compromised.

Question 8

The distinguishing characteristic of a LAN from a WAN is that it is confined to a single geographic location.

Accepted Answer

A LAN (Local Area Network) is a network that connects devices within a single physical location such as a home, school, or office building. On the other hand, a WAN (Wide Area Network) is a network that connects devices across different geographic locations, such as connecting offices in different cities. Therefore, the distinguishing characteristic of a LAN from a WAN is that a LAN is confined to a single geographic location.

Question 9

Special function cards are added to computers to augment their basic capabilities.

Accepted Answer

Special function cards, such as graphics cards or network interface cards, are commonly added to computers to extend their capabilities beyond their basic functionalities.

Question 10

Hardware refers to both electronic components and the related gadgetry that input, process, output, and store data.

Accepted Answer

Hardware includes electronic components such as processors, memory, and input/output devices as well as the gadgets that are used to interact with them, such as keyboards and displays.

Question 11

The CPU stores results of operations on the flash drive.

Accepted Answer

The CPU does not store results on the flash drive, it stores them in registers and cache memory. The flash drive is a storage device used for long-term storage of data.

Question 12

Servers in a farm coordinate their activities in a highly sophisticated and complex way.

Accepted Answer

Servers in a farm need to work together and communicate with each other to distribute workloads, ensure redundancy and failover, balance resources, and handle requests efficiently. This requires a complex and sophisticated coordination mechanism that involves various protocols, algorithms, and tools, such as load balancing, clustering, replication, data synchronization, fault tolerance, and monitoring. Therefore, the statement is true.

Question 13

MAC OS is the operating system used on the iPhone, iPad, and iPod Touch.

Accepted Answer

MAC OS is the operating system used on Macintosh computers, while iOS is the operating system used on the iPhone, iPad, and iPod Touch.

Question 14

A kilobyte is exactly 1,024 bits.

Accepted Answer

A kilobyte is actually 1,024 bytes, not bits. Each byte consists of 8 bits, so a kilobyte is 8,192 bits.

Question 15

Custom software developed in-house is the first choice of most companies due to its low costs.

Accepted Answer

Custom software is typically more expensive than off-the-shelf solutions because it is tailored to specific needs and requires more resources for development and maintenance.

Question 16

Machine code is understandable by humans.

Accepted Answer

Machine code is written in binary form, which is not readable or understandable by humans. It is the lowest level of programming language and is used directly by computers to execute instructions. However, it can be interpreted by a machine or computer processor.

Question 17

Unix is generally regarded as being more easy to use than Windows.

Accepted Answer

This statement is generally false. While Unix may have an advantage in certain areas such as command line interface and scripting, Windows has a more user-friendly graphical user interface (GUI) and is more widely used and familiar to most people. Ease of use may also depend on the individual user's experience and familiarity with the operating system.

Question 18

RAM, or the main memory of a computer, is considered nonvolatile.

Accepted Answer

RAM is actually considered volatile, meaning that its contents are lost when the power is turned off. Nonvolatile memory includes things like hard drives, solid state drives, and flash drives, which retain their contents even when the power is turned off.

Question 19

The CPU is considered "the brain" of the computer.

Accepted Answer

The CPU (Central Processing Unit) is responsible for performing most of the calculations and processing tasks in a computer, similar to how the brain is responsible for processing and controlling many functions in the human body. Therefore, it is often referred to as "the brain" of the computer.

Question 20

Special function cards are examples of input hardware.

Accepted Answer

Special function cards are examples of output hardware, as they are used to enhance the capabilities of a computer by providing additional functionalities like graphics or sound processing.
