Appendix A Hardware and Software Basics
1. | Volatility is a protected memory space created by the CPU allowing the computer to create virtual machines.
True False |
2. | Complex instruction set computer chips limit the number of instructions the CPU can execute to increase processing speed.
True False |
3. | A computer is an electronic device operating under the control of instructions stored in its own memory that can accept, manipulate, and store data.
True False |
4. | The central processing unit (CPU) (or microprocessor ) is the actual hardware that interprets and executes the program (software) instructions and coordinates how all the other hardware devices work together.
True False |
5. | The arithmetic-logic unit includes instructions and literally tells the other hardware devices what to do, based on the software instructions.
True False |
6. | The control unit performs all arithmetic operations (for example, addition and subtraction) and all logic operations.
True False |
7. | Gigahertz is the number of millions of CPU cycles per second.
True False |
8. | Megahertz is the number of billions of CPU cycles per second.
True False |
9. | Complex instruction set computer (CISC) chip, is a type of CPU that can recognize as many as 100 or more instructions, enough to carry out most computations directly.
True False |
10. | Complex instruction set computer chips limit the number of instructions the CPU can execute to increase processing speed.
True False |
11. | Primary storage is the computer’s main memory, which consists of the random access memory (RAM), cache memory, and read-only memory (ROM) that is directly accessible to the CPU.
True False |
12. | Random access memory (RAM) is the computer’s primary working memory, in which program instructions and data are stored so that they can be accessed directly by the CPU via the processor’s high-speed external data bus.
True False |
13. | Volatility refers to a device’s ability to function with or without power. RAM is volatile, meaning it must have constant power to function; its contents are lost when the computer’s electric supply fails.
True False |
14. | Cache memory is a small unit of ultra-fast memory that is used to store recently accessed or frequently accessed data so that the CPU does not have to retrieve this data from slower memory circuits such as RAM.
True False |
15. | Random access memory is the portion of a computer’s primary storage that does not lose its contents when one switches off the power.
True False |
