What is cloud computing?

• A type of memory that stores instructions waiting to be executed

• An environment of servers that provide access to resources via the Internet

• A type of computer chip that performs arithmetic and logical operations

• A storage device that uses rotating disks to store data

Why do home and business users choose cloud computing? (Choose all that apply)

• To reduce the floor space needed for equipment

• To save costs on software and hardware

What is the difference between analog and digital signals?

• Analog signals are continuous and vary in strength, while digital signals are in one of two states: on or off

• Analog signals are in one of two states: on or off, while digital signals are continuous and vary in strength

• Analog signals use binary digits (0 and 1), while digital signals use continuous wave forms

• Analog signals are used in computers, while digital signals are used in human speech

What is the purpose of cache memory?

• To store frequently used instructions and data for faster access

• To permanently store data and instructions

• To provide network connections to peripheral devices

• To convert output to video signal for the monitor

What is the difference between volatile and nonvolatile memory?

• Volatile memory loses its contents when power is removed, while nonvolatile memory retains its contents

• Volatile memory retains its contents when power is removed, while nonvolatile memory loses its contents

• Volatile memory is used for long-term storage, while nonvolatile memory is used for temporary storage

• Volatile memory is faster than nonvolatile memory

What is the purpose of a hard disk drive?

• To store and retrieve data using rotating disks

• To provide network connections to peripheral devices

• To convert output to video signal for the monitor

• To store frequently used instructions and data for faster access

What is the difference between a solid state drive (SSD) and a hard disk drive (HDD)?

• SSDs are lighter and more durable, while HDDs have larger storage capacity

• SSDs have rotating disks, while HDDs use flash-based storage

• SSDs are more expensive, while HDDs are cheaper

• SSDs have a longer battery life, while HDDs consume more power

What is the purpose of an optical drive?

• To read and write data onto CD, DVD, or Blu-Ray discs

• To provide network connections to peripheral devices

• To convert output to video signal for the monitor
