Question 1

The process of converting human-readable data into machine-readable form is called _____.

Accepted Answer

Data entry is the process of converting human-readable data into a machine-readable form, typically by inputting it into a computer system or database.

Question 2

Which of the following statements is true of organic light-emitting diode (OLED)?

Accepted Answer

OLED enables improved contrast than LCD because it doesn't require a backlight and each pixel is self-illuminating. Therefore, in areas where the image is meant to be black, the pixel can simply be turned off, resulting in true blacks and improved contrast. Option B is incorrect because OLED consumes less power than LED due to its self-illuminating technology. Option C is incorrect because OLED doesn't require a backlight. Option D is incorrect because OLED produces vibrant and bright images.

Question 3

_____ involves the simultaneous execution of two or more computer instructions at the same time.

Accepted Answer

The answer of _____ involves the simultaneous execution of two...

Question 4

_____ is a type of high-speed memory that a processor can access more rapidly than main memory.

Accepted Answer

Cache memory is a type of high-speed memory that a processor can access more rapidly than main memory. It stores frequently accessed data and instructions closer to the processor, reducing the time it takes for the processor to access them. Virtual memory is a technique used by the operating system to enable a computer to use more memory than might be physically available, while cloud memory is a type of storage that is accessed over the internet. Volatile memory refers to a type of memory that loses its contents when power is removed, such as RAM.

Question 5

Clock speed of the central processing unit (CPU) is often measured in billions of cycles per second also known as _____.

Accepted Answer

The answer of Clock speed of the central processing unit...

Question 6

_____ are used to support engineering and technical users who perform heavy mathematical computing, computer-assisted design (CAD), video editing, and other applications requiring a high-end processor.

Accepted Answer

Workstations are designed specifically for heavy computing tasks and are equipped with high-end processors, graphics cards, and memory. Desktops could also be used for these tasks, but workstation components are more specialized for engineering and technical applications. Netbooks and notebooks generally do not have the necessary components to support these types of tasks.

Question 7

A(n) _____ bus enables the central processing unit (CPU) to communicate with a system's primary storage.

Accepted Answer

An internal bus is used to connect the CPU with the primary storage (RAM) in a computer system. This bus is responsible for carrying data and instructions between the CPU and memory.

Question 8

_____ is a computing model in which an organization outsources the equipment used to support its business operations, including storage, hardware, servers, and networking components.

Accepted Answer

Infrastructure as a Service (IaaS) is a computing model where a company leases or rents their computing infrastructure from a cloud provider instead of maintaining their own data center. This includes servers, storage, networking, and hardware components. The cloud provider is responsible for maintaining the hardware and infrastructure, while the organization is responsible for managing and maintaining their software applications and data.

Question 9

A _____ is a low-cost, centrally managed computer with no internal or external attached drives for data storage with limited capabilities.

Accepted Answer

A thin client is a low-cost, centrally managed computer with no internal or external attached drives for data storage and limited capabilities. It relies heavily on a server to perform very basic operations like connecting to the internet or running applications. This type of computer is commonly used in businesses to reduce costs and increase security.

Question 10

The _____ unit of the central processing unit (CPU) performs mathematical calculations and makes logical comparisons.

Accepted Answer

The answer of The _____ unit of the central processing...

Question 11

_____ is a hard disk drive storage device that is set up with its own network address and provides file-based storage services to other devices on the network.

Accepted Answer

Network-attached storage (NAS) is a hard disk drive storage device that is set up with its own network address and provides file-based storage services to other devices on the network. NAS devices are often used in small to medium-sized businesses and homes as a central location to store and share files, media, and backups.

Question 12

A _____ is a computer employed by many users to perform a specific task, such as running network or Internet applications.

Accepted Answer

A server is a computer or device on a network that manages network resources and provides services to other computers or devices on the network. It is designed to perform a specific task or set of tasks, such as running network or Internet applications, hosting websites, storing data or managing email. The other options (A, B, and D) do not accurately describe a computer employed by many users to perform a specific task.

Question 13

The ability to increase the processing capability of a computer system so that it can handle more users, more data, or more transactions in a given period is known as _____.

Accepted Answer

The answer of The ability to increase the processing capability...

Question 14

Which of the following is related to Moore's Law?

Accepted Answer

Moore's Law refers to the principle that the number of transistors that can be placed on a microchip doubles every 18-24 months. This is a key factor in chip manufacturing and has driven the development of smaller, faster, and more powerful computer hardware.

Question 15

Which of the following statements is true of the European Union's Restriction of Hazardous Substances Directive?

Accepted Answer

The directive implements a plan to manage products at the beginning of their life cycle in an environmentally safe manner.

Question 16

The faster the clock speed of the central processing unit (CPU), _____.

Accepted Answer

As the clock speed of the CPU increases, it requires more power and generates more heat, which can cause issues with the stability and longevity of the processor. This is why cooling solutions such as fans or liquid cooling are often necessary to keep the CPU running at high speeds without overheating. The other choices are not directly related to the clock speed of the CPU.

Question 17

A(n) _____ is a server that houses many individual computer motherboards that include one or more processors, computer memory, computer storage, and computer network connections.

Accepted Answer

The answer of A(n) _____ is a server that houses...

Question 18

_____ is an advanced optical disc technology that can store up to 3.9 terabytes, roughly 75-150 times more data than the Blu-ray optical disc system although it is the same size and shape as a regular digital video disc (DVD).

Accepted Answer

The holographic versatile disc has the capacity to store up to 3.9 terabytes of data, which is significantly more than the capacity of other optical disc technologies like the Blu-ray. It is the same size and shape as a regular DVD. Therefore, option A is the correct answer.

Question 19

_____ are the most powerful computers with the fastest processing speed and highest performance.

Accepted Answer

Supercomputers are specifically designed for performing complex calculations at the highest speeds and processing power. They are typically used in scientific and research fields for tasks such as weather forecasting, modeling and simulation, and drug discovery. Blade servers and workstations are also powerful computing systems, but they do not have the same level of performance as supercomputers. Mainframe computers are designed for handling large amounts of data and transaction processing, but their processing speed and performance is not as high as that of supercomputers.

Question 20

_____ are used in standardized tests, including the SAT and GMAT tests, and to record votes in elections.

Accepted Answer

Optical mark recognition (OMR) systems are specifically designed for reading filled-in bubbles or checkboxes on forms, making them ideal for standardized tests and recording votes in elections. Magnetic Ink Character Recognition (MICR) devices are typically used to read the magnetic ink on checks, while optical character recognition (OCR) systems are designed for reading printed text. Speech recognition devices are used to convert spoken words into text.
