Suzi is a writer who is using her keyboard to type a story. When she saves her work, her computer issues a command and returns the results, which she checks to ensure that her work has been saved properly.
The __________ in Suzi’s computer is responsible for the operation sent to it by the software.
- CPU
- RAM
- ROM
- keyboard
RATIONALE
When Suzi clicks to save her work, this command is sent to the computer’s central processing unit (CPU). The CPU manages the operations or instructions it receives from software programs. Random-access memory (RAM) and read-only memory (ROM) indicate the locations where the data is stored in the computer, but do not manage instructions sent to them by software.

Which of the following statements about the relationship between hardware and software is true?
- Software consists of instructions that tell the hardware what to do.
- A flash drive is an example of software.
- Hardware can be present in intangible form.
- Software and hardware can act independently of each other.
RATIONALE
It is true that software consists of instructions that tell hardware what to do. Software controls and commands hardware.
The other statements are false. Software and hardware cannot function without each other. Without software, computer hardware is useless. Conversely, software cannot be used without supporting hardware. Hardware is the physical, tangible components of a computer; software comprises the intangible components. A flash drive is an example of computer hardware.

Select the file size that is the SMALLEST.
- 6,000 GB
- 90,000 KB
- 3 TB
- 2 MB
RATIONALE
If we consider the units only, the order (smallest to largest) is KB, MB, GB, and TB. However, we must also consider the number of units. We can rewrite each example in the same unit and order, as follows:
2 MB = 0.002 GB
90,000 KB = 0.09 GB
3 TB = 3,000 GB
6,000 GB = 6,000 GB
The smallest file size is 2 MB.
