Which of these is faster than RAM?
file paths
L caches
input devices
cloud memory
L caches
Which statement is MOST accurate?
Faster memory is more expensive.
All kinds of memory cost the same.
Slower memory is easier to find.
In the cloud, memory is free.
The statement "Faster memory is more expensive" is the most accurate. Generally, memory technologies that offer higher speeds and better performance tend to be more expensive than slower memory options.
Which part of the computing process occurs before storage is used?
input
networking
output
updating
The input part of the computing process occurs before storage is used. Input refers to the stage where data or instructions are received from external sources and prepared for processing or storage. Once the data is inputted, it can then be stored in storage devices.
Which computing component is responsible for coordinating memory management?
the hardware
the operating system
the applications
the user
The operating system is responsible for coordinating memory management in a computing system. Memory management involves allocating and deallocating memory resources, managing the virtual memory system, and ensuring efficient utilization of available memory. The operating system handles these tasks to optimize memory usage and provide necessary memory resources to applications and processes.

Carla wants to learn more about how CPUs work. Which of these videos would be the MOST useful to her?
“How Input Devices Work”
“Storage Devices for Beginners”
“Computer Output Devices 101”
“Introduction to Computer Processing”
The video titled "Introduction to Computer Processing" would be the most useful for Carla if she wants to learn more about how CPUs work. This video is specifically focused on computer processing and would provide the most relevant information about CPUs and their functioning in a computer system.
What is the MAIN advantage of solid-state drives?
They are very easy to fix.
They are very affordable.
They are very fast.
They are very secure.
The main advantage of solid-state drives (SSDs) is that they are very fast. Compared to traditional hard disk drives (HDDs), SSDs have significantly faster read and write speeds, which results in faster boot times, quick file access, and overall improved system performance.
What is the difference between hardware and software?
Software is physical; hardware is not.
Hardware is physical; software is not.
Software is open-source; hardware requires a license.
Hardware is open-source; software requires a license.
The difference between hardware and software is that hardware refers to the physical components of a computer system, such as the processor, memory, and peripherals, while software refers to the programs and instructions that are executed by the hardware to perform specific tasks. In other words, hardware is physical and tangible, whereas software is intangible and consists of instructions and code.
Which of these BEST describes a built-in solid-state drive?
an input device
an output device
a storage device
a processing device
A built-in solid-state drive (SSD) is best described as a storage device. It is a type of non-volatile memory that is used for data storage in computers and other electronic devices. Unlike traditional hard disk drives (HDDs), which use mechanical parts, SSDs use flash memory technology to store data, making them faster, more reliable, and more durable for storing and retrieving data.
Which of the following statements BEST describes a computer?
It is a thinking machine.
It is a mathematical machine.
It is a mechanical converter.
It is a quantum technology.
The statement "It is a mathematical machine" best describes a computer. Computers are devices that manipulate and process data using mathematical operations. The underlying architecture and principles of computer systems are based on mathematical concepts and algorithms. Computers are designed to perform calculations, solve problems, and execute instructions based on mathematical operations and logical reasoning.
What is the MAIN advantage of a hard drive?
It offers the fastest way to access data.
It doesn’t require magnetization.
It is the most secure storage method.
It is very affordable.
The main advantage of a hard drive is that it provides a relatively affordable storage method. Hard drives, also known as hard disk drives (HDDs), have been widely used as a primary storage medium in computers due to their lower cost per gigabyte compared to other storage options like solid-state drives (SSDs). Although hard drives may have advantages in terms of capacity and durability, their main advantage is typically associated with affordability.
What is a computer’s primary memory MOSTLY used for?
communicating with peripherals
loading the operating system
providing short-term storage
managing the solid-state drive
A computer's primary memory, also known as RAM (Random Access Memory), is mostly used for providing short-term storage. RAM is a volatile memory type that allows the computer to temporarily store data that is actively being used by the CPU. It holds instructions and data for quick access and retrieval by the processor, enabling faster execution of programs and tasks. However, RAM does not handle long-term storage of data or manage the solid-state drive.
What are the three main operating systems?
Chrome, Firefox, and Bing
Amazon, Facebook, and Apple
Microsoft, Google, and Adobe
Windows, macOS, and Linux
